home Production Cast tips Photo gallery Contacts Production The Precision Billet Plant produces steel and iron castings using the gasified casting method. Model production For our model production, the main technology for obtaining models for serial and repeated orders is the method of "baking" models from pre-foamed granular polystyrene - the prepared material is blown into a mold, followed by a short exposure in an autoclave under the influence of temperature and pressure, and, finally, cooling the mold and extracting the model. For one-time or small-batch orders, the technology of manufacturing models of castings from solid expanded polystyrene by the method of 3D milling is used. The 3D milling method applied to the production of models from expanded polystyrene opens up a number of possibilities: unlimited possibilities in terms of the shape of castings; the ability to manufacture castings of complex body parts without the manufacture of expensive model equipment; high accuracy of making models - the permissible deviation of the position of the cutting tool is not more than 0.01 mm; unconditional repeatability of models, provided by software and hardware; a differentiated approach to accounting for the shrinkage of the material poured into the mold, depending on the local degree of difficulty in shrinkage; quick correction of shapes in case of unsatisfactory results of filling; reduction of the lead time for the order for the supply of castings to 3-4 working days in special cases. Melting section The melting section of our foundry is equipped with a melting unit ITPE-0.4 / 0.35 TG2 manufactured by OOO Termolit, Melitopol. The installed pair of alternately operating melting units can significantly reduce the loss of working time for technological operations of maintenance and replacement of crucibles. The smelter has a modern laboratory complex for express analysis of the chemical composition of materials in the process of smelting and analysis of selected samples for issuing quality passports for products. At the moment, to determine the composition of the samples, instruments are used: Spectrometer DFS-71 from OKB “Spektr” , St. Petersburg and carbon analyzer “METAVAK-CS10”, OOO NPO “EKSAN”, Izhevsk. Foundry section The technology of casting according to gasified models (LGM), implemented in the conditions of our enterprise, makes it possible to obtain castings of a complex configuration weighing from 100 grams to 400 kilograms, dimensional and weight accuracy up to class 7 in accordance with GOST 26645-85.
