COMPANY PRODUCTS SUPPORT CONTACTS NEWS EN LIFTING EXPECTATIONS ABOUT US A cutting edge company moving towards the future Our integrated production process is based on modern machinery and cutting edge technologies. It begins with the steel coil annealing and ends with the packing of the finished products. Our QA laboratory is equipped with sophisticated systems and advanced tools whose use is enhanced by consolidated working routines. Kito Italia’s team of technicians, designers and engineers carries out R&D on products and processes. We also collaborate with universities and research centers. CHAINS Kito Chain Italia is specialized in production of high resistance industrial chains and rod steel. All chains are produced in compliance with technical regulations and highest quality standards and can be used for lifting, slings and lashing applications. The raw material used in the production of chains is wire rod, which is stored in large coils. A first step consists in cleaning and preparing the wire for the subsequent phases in a process called pickling. Subsequently, the wire rod undergoes an annealing process which allows obtaining a better crystalline structure and, consequently, a more malleable material. Once the wire rod is drawn and its diameter is reduced to the approximate size, it is bent into links of specific diameters depending on the type of chain. The extremities of each link are welded together, after the individual links have been connected to form the chain. The welding process requires the application of high voltage current to heat the rod and press the ends together. At this point, the chain is complete; however, the process so far described does not guarantee flawless links, thus the need to check each chain visually to substitute or to repair defective links. For the following process of hardening and tempering of the chain we use an induction treatment furnace. Once the chain is tempered to the designed degree, it is sandblasted and then calibrated by applying a load which is 2.5 times the weight of the chain. The calibration further guarantees that each single link has been properly welded. It also stretches the links to their specified length. The final inspection tests and validates the mechanical properties of the chain on a section taken from the final product. The selected section is put under strain with the use of special machinery until it brakes; the load at the breaking point should be equal or greater than the minimum required by law. The final phase consists in painting the chain in the desired colors. Subsequently, we stock the chain in our warehouse until it is time for shipment to our clients all over the world. ACCESSORIES AND MASTER LINKS New synergies and investments have allowed us to expand into a new type of product: hooks of different sizes, connectors and master links for use with bridge cranes, hoists and various applications. All the components for the final slings are hot worked from alloyed steel rods of different diameters according to the size of the final product. The master links or rings are produced in a manner similar to the chains using wire rods and coils or alloyed steel bars. The rings with the diameter of less or equal to 20mm are cold formed and the extremities are welded by electric resistance. Larger diameter rings between 20 and 70mm are hot formed and welded with flash welding machinery. Excess material, ragged edges and protrusions from the welding processes are removed with special trimming devices. Information that allows for the identification of the type of ring and the lot it belongs to is stamped onto each ring. After marking, the rings go through a tempering phase which we carry out in four high tech computer controlled furnaces. In this tempering process the metal, which is first heated and then quickly cooled in oil, acquires the physical properties necessary to withstand continuous mechanical stresses. The temperature of tempering process is selected according to the type of the final application the rings will be employed to. Hooks and other forged accessories before tempering undergo drilling, machining and upsetting procedures according to their need. For this types of process we use computer numerical control machines, which allow for obtaining calibrated holes, precision smoothing and rounding off. In the end hooks, rings and links are degreased, washed and phosphate coated before being painted by a powder coating process with poly epoxide in our high tech plant. As for the chain, hooks and rings must satisfy precise quality standards and technical regulations. Therefore, they must be validated for proper resistance and dimensions. Any possible deviation from the norm is eliminated; this affords us to guarantee the optimal quality of our products.
