MIGRATION TRENDS IN KAZAKHSTAN: EXPLORING MIGRATION CAUSES AND FACTORS
Authors: BOKAYEV Baurzhan , TOREBEKOVA Zulfiya , DAVLETBAYEVA Zhuldyz , KANAFINA Aigerim
Published: June 2021

The article examines the issues of emigration of the population of Kazakhstan, the reasons and factors influencing the decision of citizens to leave the country. The analysis was based on the fall 2018 sociological poll results, which comprised responses from 3,215 Kazakhstani citizens and in-depth interviews with 143 experts in different civil service, science, education, and economics branches. The results thus obtained showed that labor migration predominated: people were driven by the desire to earn more, to realize their professional potential, to receive better education and professional training. We have also discovered that the low quality of education and lack of favorable conditions for the development of the younger generation are the two other causes of the outflow of Kazakhstanis from their homeland. The state is not doing enough to persuade young specialists and scientists to remain in the country, which explains the gradual increase of intellectual migration and brain-drain. The results brought us to a conclusion that certain political factors, including poorly protected legitimate rights, corruption and certain related reasons, are fairly important for those determined to leave. Many of those who are ready to leave, the older generation in particular, are kept back by family and friendly ties and the habitual life style.
RETURN MIGRATION TO TAJIKISTAN: FORMS, TRENDS, CONSEQUENCES
Authors: RYAZANTSEV Sergey , KHONKHODZHAYEV Farrukh , AKRAMOV Sharif , RYAZANTSEV Nikita
Published: June 2021

This paper aims to study the trends of labor migration (voluntary and forced) from Russia to Tajikistan and the peculiarities of the reintegration of returning migrants into Tajik society. Labor migration is the main driver of economic growth for Tajikistan and the most effective tool in the national fight against poverty. However, many migrants from Tajikistan do not have a formally documented status in Russia, which makes their predicament extremely difficult and vulnerable. One of the most sensitive measures for Tajik labor migrants was the introduction of administrative penalties through expulsion and the imposition of a massive ban on labor migrants from entering the Russian Federation. This has led to an increase in the return migration of Tajik migrants to their homeland. The article clarifies the concept of return migration, reveals the reasons for the return of labor migrants from Russia to Tajikistan and identifies the specific features of reintegration and the socio-economic situation of returning migrants in Tajikistan. The authors establish that a significant share of returning migrants have already reached retirement age after working in Russia for decades, but they do not receive a pension either in Tajikistan or in Russia. Unfortunately, as of today the Government of Tajikistan has not developed any special programs for the reintegration of returning migrants due to lack of funds and lack of experience in this area. Most returning migrants are forced to solve their problems on their own or resort to the help of their families and relatives. In fact, the government does not hold an interest in the massive return of labor migrants, since the increase in their number worsens the socio-economic situation and the general state of the labor market.
A Generalization of Stiebitz-Type Results on Graph Decomposition
Authors: Zeng Qinghou , Zu Chunlei
Published: June 2021

In this paper, we consider the decomposition of multigraphs under minimum degree constraints and give a unified generalization of several results by various researchers. Let $G$ be a multigraph in which no quadrilaterals share edges with triangles and other quadrilaterals and let $\mu_G(v)=\max\{\mu_G(u,v):u\in V(G)\setminus\{v\}\}$, where $\mu_G(u,v)$ is the number of edges joining $u$ and $v$ in $G$. We show that for any two functions $a,b:V(G)\rightarrow\mathbb{N}\setminus\{0,1\}$, if $d_G(v)\ge a(v)+b(v)+2\mu_G(v)-3$ for each $v\in V(G)$, then there is a partition $(X,Y)$ of $V(G)$ such that $d_X(x)\geq a(x)$ for each $x\in X$ and $d_Y(y)\geq b(y)$ for each $y\in Y$. This extends the related results due to Diwan, Liu–Xu and  Ma–Yang on simple graphs to the multigraph setting.

Published: June 2021

In this paper, we prove $\mathrm{ex}(n, C_{2k})\le (16\sqrt{5}\sqrt{k\log k} + o(1))\cdot n^{1+1/k}$. This improves on a result of Bukh and Jiang from 2017, thereby reducing the best known upper bound by a factor of $\sqrt{5\log k}$.
A Geometric and Combinatorial Exploration of Hochschild Lattices
Authors: Combe Camille
Published: June 2021

Hochschild lattices are specific intervals in the dexter meet-semilattices recently introduced by Chapoton. A natural geometric realization of these lattices leads to some cell complexes introduced by Saneblidze, called the Hochschild polytopes. We obtain several geometrical properties of the Hochschild lattices, namely we give cubic realizations, establish that these lattices are EL-shellable, and show that they are constructible by interval doubling. We also prove several combinatorial properties as the enumeration of their $k$-chains and compute their degree polynomials.

DISPARITIES IN THE PERCEPTION OF BUSINESS RISKS IN CONNECTION WITH THE ACHIEVED EDUCATION OF THE OWNER/MANAGER AND DOING BUSINESS
Authors: Dvorský Ján , Belás, Jr. Jaroslav , Çera Gentjan , Bilan Svitlana
Published: June 2021

The article aims to identify disparities in the perception of business risks connected with the achieved education of the owner/manager and doing business in the SME segment. The study's empirical part was realised on 1585 fulfil questionnaires of SMEs in the Visegrad countries (V4). The Chi-square test and Z-test verified the formulated statistical hypotheses. The research results brought a common and different perception of business risks between the examined groups of entrepreneurs. The results showed that the relationship between education and the entrepreneur's business area is not a statistically significant factor in the perception of market, financial and legal risk sources. On the contrary, disparities are significant in the perception of selected sources of management, strategic and personnel risk, between groups of entrepreneurs regarding the relationship between education and the business of the entrepreneur. Entrepreneurs whose education is related to the area of business perceive the sources of personnel risk (employee turnover and the effort of employees to increase their performance) more positively than entrepreneurs whose education is not related to business.
PUBLIC PROCUREMENT IN THE CONDITIONS OF THE SLOVAK REPUBLIC WITH REGARD TO THE PARTICIPANTS IN THE PROCUREMENT
Authors: Bednárová Lucia , Michalková Silvia , Vandžura Stanislav
Published: June 2021

Public finances are a term used to denote specific financial relations and operations taking place within the economic system between public administration institutions, on the one hand, and other entities, on the other. From an economic point of view, a public contract means an efficient allocation of resources with the aim of material and material provision of public administration bodies with such services that these bodies cannot or do not want to secure themselves. Through public procurement, a relatively high volume of public spending is realized in each developed country. Public procurement of goods, services and works by public institutions currently accounts for a relatively high percentage of GDP, estimated at more than 15% in the economies of Central and Eastern Europe. The area of procurement is one of the key areas where the public and private sectors interact financially with each other. As part of the paper, we primarily deal with below-limit and above-limit contracts in public procurement in the Slovak Republic. As part of the research, we focused on the period from 2016 to 2019. The paper provides an overview of the number of procedures in public procurement for the period from 2016 to 2019. In this comparison of data, we try to demonstrate the strength of public procurement in the public sector as well as the volume of financial flows spent on procurement. Within the issue of our research, the acquisition of relevant documents as well as verified procedures is very problematic, as we do not have a significant number of sources of professional and science publications related to these topics in the Slovak Republic.
ENTREPRENEURIAL ORIENTATION IN SUPPLY CHAIN MANAGEMENT: A SYSTEMATIC REVIEW
Authors: Cortes Andres Felipe , Lee Younggeun , Cortes Juan David , Liñan Isidro
Published: June 2021

Companies around the world need to reconcile the need to differentiate their offerings and remain entrepreneurial in a competitive environment while also running extremely efficient and effective operations. Surprisingly, however, limited studies have provided a synthesis and overview of existing research exploring important links between the entrepreneurship and supply chain management (SCM) fields. In this paper, we aim to address this issue by developing a systematic review of research exploring the link between entrepreneurial orientation (EO) and SCM, while synthesizing the most relevant findings in this intersection. We also aim to promote the development of this topic by providing relevant future research directions. To do so, we conducted a systematic review on the topic of EO published in SCM journals from 1989 to April 2020. We summarize 14 relevant articles on EO in SCM and conclude that research joining these fields is surprisingly scant despite the development of both EO and SCM literature over extended periods of time. We find that although existing research recognizes that entrepreneurial behavior is key for a successful supply chain orientation and to develop more efficient and value-creating supply chains, theoretical development and empirical examination in specific supply chains and multiple industries is required. We uncover and propose specific opportunities to advance this research effort.

Published: June 2021

Undoubtedly, entrepreneurial knowledge is a prerequisite for the survival of every business organization. To this, the contribution of Small and Medium Enterprises (SMEs) in the socio-economic development in most developing economies cannot be underestimated. Both developed and developing countries are living testimonies of their contributions to their nation’s growth and development. However, extant literature shows that as competition and innovation intensify in the global business market, many SMEs in developing countries are constrained by external forces that hinder the sustainability of these businesses.   Hence, this paper aims to find out the mitigating factors warranting SMEs’ sustainability from the viewpoint of entrepreneurs and business owners, particularly in the manufacturing sector of Ghana, a Sub-Saharan Africa region. To achieved this objective, the study deployed a simple random sampling technique with 370 valid responses through a structured questionnaire for the analysis. Relying on PLS-SEM (partial least square and structural modeling) with the aid of ADANCO 2.2.1 software version revealed that factors such as financial challenges, technology; market penetration & acceptability; and research & development are barriers facing SMEs sustainability in the Ghanaian manufacturing sector. This study would be beneficial to entrepreneurs and business owners of SMEs in most developing countries and provide deeper insight into the SME literature at large. This study would further strengthen SME entrepreneurs and business owners to fully devise strategies that can help them to override such migrating challenges and equipped them to effectively stay competitive in the long term for the firm’s growth and survival. The limitation and future research directions are equally presented in the paper.

The development of the use of advanced technology in the form of computerized applications has become a trend and is widely used in all fields. One of the fields that take advantage of the use of automated technology is the library. However, not all of these applications can run well by the application creation hypothesis. For this reason, application testing is required before implementation to avoid bugs or errors. Consider the application testing phase importance, testing with the black box method was carried out on library applications using the Boundary Value Analysis (BVA) technique in this study. These testing methods and techniques were chosen. When the application is implemented, there will be no more errors caused by differences in the value data during the input process with the stored value data, after testing using the black box method with the BVA technique and documentation of each test. All the library application functions have been running according to the initial application plan made, and there are no more bugs or errors when the application is run.

Published: June 2021

Clean water is a basic human need that is used for daily activities. However, as the population increases, the need for water also increases. One method of conserving water resources is Rainwater Storage. Conventional rainwater storage cannot be appropriately monitored, maintain water quality, and only works like a container, which, if left to continue, can result in the collected rainwater becoming a source of disease and dangerous for users. This research aims to create an automatic rainwater collection system and water quality monitoring that can control the flow of water that will enter the reservoir to keep the water entering the reservoir of good quality. In the manufacture of this system, three sensors are used, including a pH sensor, a water turbidity sensor, and a TDS (Total Dissolved Solids) sensor. In determining water quality, the k-Nearest Neighbor (k-NN) method is used to classify whether the water is feasible, less feasible, or not suitable for consumption. Data transmission uses the ESP8266 WiFi module, and monitoring data can be viewed on the website. Testing the system using an experimental method, and in testing, it is found that this system can classify water quality with an accuracy rate of 70%.

Published: June 2021

As a result of geophysical survey in Hovsan field it was revealed that Miocene sediment rocks consist of the alternation of sand and aleurite clays and a small amount of limestone. The clay is predominantly grey, solid sands and aleurites are small-grained. In the geophysical logging survey it was defined that the oil is basically accumulated in the sands and aleurites. Alongside with industrial oil in the well No 1879, a great amount of gas has been obtained as well. The porosity in Miocene rocks in the well No 1867 is equal to 24 % and it fluctuates between 6 and 30 % in the well No 1879, the permeability in both wells varies up to 10 mkm2.

Numerous research surveys justified that the major purpose of well stimulation is the productivity increase by means of elimination of bottomhole damages in formation and well. This process appears directly by creating a certain structure in formation. Thus, in field conditions as a stimulation method the fracturing, acid treatment of reservoirs, as well as acid treatment of cracks (acid fracturing) are generally applied. Field studies showed that due to the radial nature of the flow the pressure decrease is basically occurs near the well and in the bottomhole. The analysis justifies that any damage in this area significantly increases the pressure reduction and the effect of such damages may be presented by means of “skin-factor”. The authors present more generalized concept of “skin factor” combining the most important aspects of bottomhole zone damages of production well. These processes create additional resistance decreasing production. From our perspective, the well stimulation is the productivity increase. In this case there is scientific-practical sense to consider the stimulation as a method for “skin-effect” value reduction. The paper offers a new parameter of “generalized skin-effect” or “generalized skin-factor” showing positive results with negative values, i.e. increases performance and productivity.

For transportation of natural gas through the pipelines of compressor stations, its pressure increases. Up to 10 percent of this energy is used for the slipping by the pipeline walls and the most to the gas pressure reduction. The paper reviews the issues of efficiency increase of gas provision network of our Republic due to the decrease of energy losses in transportation, distribution and regulation systems of natural gas. For this purpose, the energy losses associated with the decrease of natural gas pressure in gas distribution plants and gas control units have been studied, as well as using efficiency of this energy justified. It was defined that the pressure of natural gas being transported to the customers through the delivery main, reduces down to the set value via throttle valves in gas distribution plants at first and in gas control units subsequently, which leads to the loss of significant portion of initial energy delivered through compressor stations during gas compression. The studies showed that using special traditional throttling valves instead of expansion units, so-called detanders, enables obtaining electrical energy via environmentally-friendly method with minimum investments due to the surplus gas pressure.

Published: June 2021

The distribution of thermal waters in the structures of Middle Kur depression is different. Thus, Barda, Terter and Aghjabedi studied structures are characterized with the highest water inflow. The water temperature reaches up to 50 оС in the flow. Chloride-natrium methane waters are distributed here predominantly. The migration of thermal waters is largely effected by thermo-lift and gas factor. The most prospective water-bearing complexes are the Cretaceous and Miocene (Maikop, Chokrak) sediments. According to the results of technical-economic feasibilities (temporary and permanent conditions) of Barda, Terter and Aghjabedi studied areas the thermal waters from Maikop horizon have healing properties. It is necessary to enhance the further research surveys on these areas of Middle Kur depression.

The article deals with the problems associated with the ""invasion"" of produced water into the composition of drilling muds in the process of drilling wells in anomalous conditions. It is marked that various types of complications, particularly, debris and collapses, emersion and adsorption cause very serious problems in the well construction, for the elimination of which large investments are required. For example, drilling mud influenced by produced water was used in some fields of the Republic. The electrical conductivity parameter was estimated based on the carried out research. This indicator allows evaluating the physical-chemical properties of the drilling mud before and after the treatment with formation fluid. It should be noted that the good electrical conductivity of the drilling mud is also significant for geophysical surveys. In order to preserve required properties of the drilling mud under conditions of ingress into the composition of the produced waters, the treatment of the drilling mud with salt-resistant polymeric reagents is recommended.

Authors:   ", Jafarov R.R. ,   Oil-Gas Scientific Research Project",   Institute, Azerbaijan Republic
Published: June 2021

The capacity method is prevalently applied for reserves calculation of oil-gas fields in Azerbaijan. Siazan section consists of oil-bearing suits and horizons, in lithological respect is characterized with terrigenic and fractured reservoirs. To mark oil-bearing interlayers in the section is quite hard and in some cases even impossible. Thus, oil reserves in Siazan-Nardaran, Sadan and Amirkhanly areas of Siazan monocline were calculated via the statistic way alongside with capacity methods. The comparison of obtained results justified that in conditions of cracked reservoirs the methods show comparatively better performance.
New well-head device for shock-wave treatment of bottomhole zone
Authors:   Project Institute ", Baspaev E.T. ,   OPTIMUM",   LLC, Aktau, Kazakhstan
Published: June 2021

For the implementation of shock-wave treatment on bottomhole zone of formation, there are various devices not providing efficient resonant shakedown of borehole fluid column creating shock waves of pressure and vacuum, which is not efficiently productive and reliable as well. To reduce filtration resistances and reset hydrodynamic relation of the reservoir and well, a new construction of wellhead device for shock-wave treatment on bottomhole zone, which may be used for increasing oil recovery rate via the effect through the well on Productive Series during completion and repair of producing well, has been developed. By developing a reliable and constant pressed airflow with low pressure, the paper solves the task of increasing the frequency of closing and opening of wellhead device, enabling to use it for creating shocking waves of pressure and vacuum in the well. The implementation of developed device improving hydrodynamic relations and hereby, simplifying filtration in the “reservoir-well” system, puts in production low permeable and isolated zones of Productive Series, which promotes the oil recovery rate increase and reduce oil prime cost as well.
Diagnosis of the rheological properties of oil emulsions considering watercut and temperature factors
Authors:   Azerbaijan State University of Oil and Industry, Zeynalova G.A.
Published: June 2021

It is well known that one of the factors adversely affecting the operational efficiency of infield technological oil pipelines is persistent oil emulsions formed due to the oils watercut. These hardly demulsifible emulsions with abnormal rheological features show non-Newtonian properties. Depending on the temperature and watercut degree, the viscosity of these emulsions varies widely. The specification of viscosity and other physical-chemical properties in oil-field experience is carried out via laboratory testing of oil samples according to the standards. Based on the roto-viscosimetric studies of oil samples with various temperatures, an empiric formula for the specification of oil emulsions viscosity depending on watercut degree is offered. It was defined that the offered formula enables with permissible error to specify the viscosity of abnormal emulsions considering the changing watercut and temperature aspects.

El Sistema Nacional Anticorrupción mexicano en "El Libro Vaquero". Deficiencia estructural y solapamiento de responsabilidades
Authors: Hernández Nieto Laura Nallely , Rubinstein Iván Facundo
Published: June 2021

El presente artículo indaga en la construcción discursiva del llamado Libro Vaquero Anticorrupción a través del análisis socio-semiótico de su estructura formal, su narrativa y su modo de abordar el lanzamiento del Sistema Nacional Anticorrupción (SNA) en México. La principal conclusión a la que se arriba es que el discurso oficial del SNA responsabiliza de forma casi exclusiva a la sociedad civil por las condiciones actuales en relación a la corrupción. De esta forma, se invisibilizan las causas estructurales, principalmente en relación a los actores del campo de poder (entendido como la conjunción del campo político y económico).

El cómic como experiencia (un Beta-test de la narratividad del medio a partir de la obra de Begoña García-Alén)
Authors: García López Óscar
Published: June 2021

Las particularidades del cómic pueden favorecer su empleo como soporte en el que desarrollar un relato pero esta circunstancia no implica que ese potencial narrativo se imponga como condición exclusiva y excluyente. Las obras de un grupo emergente de autoras y autores que están poniendo a prueba los convencionalismos del medio y expandiendo sus fronteras hacia nuevos territorios han reavivado un debate sobre el estatuto del cómic en el que late de fondo una pregunta: ¿qué es la narrativa? Adoptando como herramienta de análisis la teoría narratológica de Monika Fludernik —que reformula desde una perspectiva cognitiva los criterios estructuralistas empleados para definir lo narrativo—, este texto intenta trazar un itinerario por esas nuevas manifestaciones liminales del cómic —en cuyo última frontera podríamos situar la abstracción— utilizando como mapa la obra de Begoña García-Alén.

Instinto queer y escenas camp en Arsène Schrauwen de Olivier Schrauwen
Authors: González de Ozaeta Mara
Published: June 2021

Este artículo estudia los aspectos queer y camp en Arsène Schrauwen (2014) de OlivierSchrauwen. El autor utiliza el artificio, la parodia y el vínculo entre narración gráficay convencional para representar sexualidades alternativas y turbaciones propias delcuestionamiento histórico y la dominación masculina.En Contra la interpretación (1969), Susan Sontag nos invita a ignorar la exégesis tradicionalpara hacer una erótica del texto. Gracias a que Olivier Schrauwen vinculaerotismo y lectura, puede analizarse como lo hubiera querido la ensayista estadounidense.Además, lo camp desarticula el dominio de la lógica, la ética y los patronesestéticos constituyéndose al margen de la alta cultura y estableciendo el epítome dela libertad creadora: esa ciudad ideal que el imperio del hombre occidental deseaconquistar.
Lo individual y lo social en el Joker de Batman: el caballero de la venganza
Authors: Plana Alsina Meritxell
Published: June 2021

La separación entre Batman: el caballero de la venganza y la tradición de personajescomo Batman o Joker es abismal. Para analizar dicha obra es esencial comparar laversión tradicional con la de este cómic y así proseguir con el estudio intrínseco deesta última versión. Lo más complejo de la obra es la propia creación del personaje deJoker en un laberíntico entramado de construcción social y política que llevan a unamadre cariñosa a convertirse en un/a criminal con todas las implicaciones inherentesa la trama.

Entre la forgerie y el pastiche: la obra tributo a Tintín de Yves Rodier
Authors: Pérez-Gómez Miguel Ángel
Published: June 2021

Entre los apócrifos de Las aventuras de Tintín existen aquellos que, por imitación del estilo gráfico y el narrativo, citan la obra de Hergé desde la seriedad. Podemos definirlos como una imitación de un estilo sin la función satírica; entre estos podemos incluir los textos de segundo grado que están pensados como una continuación o extensión de una obra preexistente. Yves Rodier ha realizado diferentes pastiches/forgeries imitando el estilo de Hergé. A través de este artículo se analizan su uso de la forgerie y el pastiche para crear obras apócrifas que pueden leerse como si formaran parte del universo oficial.
Más que superhéroes: filosofía del lenguaje, perennialismo y los cimientos de la realidad en Grant Morrison
Authors: Ramos Vera Mario
Published: June 2021

Los planteamientos especulativos que, desde el ámbito de la filosofía del lenguaje, ha propuesto el guionista de cómics y ensayista Grant Morrison resultan pertinentes y relevantes por su profundidad teórica. Por medio del género de superhéroes, concebido como vehículo narrativo, es posible acceder a una propuesta nítida que recurre a la filosofía del lenguaje para tantear una vertiente ontológica. Para ello, resulta pertinente abordar las relaciones que Morrison sugiere entre pensamiento y lenguaje, entre las palabras y los signos en su vínculo y correspondencia con la realidad. Desde una pluralidad de perspectivas, congruentes con su planteamiento posmoderno, el superhéroe es capaz de incardinar en sí mismo cuestiones filosóficas y lingüísticas de enorme trascendencia que han traslucido en todo momento y en todo lugar, con diferentes ropajes, para hacer llegar un mensaje ético y ontológico concreto.
El vecino. Historias. Desplazando el significado de los superhéroes
Authors: Pérez García Juan Carlos
Published: June 2021

El vecino. Historias (2019) es una novela gráfica de Santiago García y Pepo Pérez. Forma parte de la serie El vecino (2004-hoy), desarrollada en formatos y tonos narrativos variables; su argumento parte del contraste entre dos mundos, el cotidiano (la vida corriente de unos vecinos) y el fantástico (uno de ellos es un superhéroe). El vecino. Historias recopila historias cortas cuyas estrategias artísticas son analizadas en este ensayo. Cada una plantea diferentes juegos formales y tonales, a menudo desde perspectivas metalingüísticas que cuestionan las convenciones y formatos del cómic. También se exploran los significados ideológicos implícitos en los códigos de superhéroes.
Entrevista con Paco Roca
Authors: Claudio Esther
Published: June 2021

Paco Roca es probablemente el autor más conocido de España. Saltó a la fama con la adaptación cinematográfica de Arrugas (Astiberri, 2007) y desde entonces sus novelas gráficas han sido un éxito de crítica y público. Los surcos del azar (Astiberri, 2013), El invierno del dibujante (Astiberri, 2010) o La Casa (Astiberri, 2015) entre otras muchas ya forman parte de la producción española más destacada a nivel nacional e internacional, especialmente desde que comenzaron a publicarse en inglés por Fantagraphics. En cada obra se propone un acercamiento diferente a la naturaleza humana, siempre con la delicadeza y la sobriedad de un estilo que se aleja de dramatismos para profundizar en los matices que facilitan la empatía del lector o lectora con los personajes. La memoria, el pasado, la historia y la creación artística son ejes fundamentales de su narrativa y en esta entrevista exploramos Regreso al Edén, recién publicada por Astiberri (2020), probablemente su reflexión más elaborada en torno a cada uno de estos temas. Además, comentaremos dos de sus últimas publicaciones y muy relacionadas con Edén: La Casa y El tesoro del Cisne Negro (Astiberri 2018).
Spritzgießtribometer: Produktivität rauf – Zykluszeiten runter
Authors: Gogoll Volker
Published: June 2021

Ein gespritztes Kunststoffformteil muss am Zyklusende soweit abgekühlt sein, dass es korrekt entformt werden kann. Das heißt, das Teil muss frei fallen oder mit Handlingunterstützung sauber entnommen werden können. Aber nicht nur die Abkühlung der Werkzeugoberflächen entscheidet allein über das zuverlässige Entformen aus der Auswerferseite. Ein entscheidender Parameter ist die Haftung zwischen der Werkzeugwand und dem spritzgegossenem Formteil, die so gering wie möglich sein muss. Erreichen lässt sich das über funktionale Werkzeugoberflächen.
