Steel Castings | Public Li Xin Machinery (certified) | Rural counties castings from Linyi Public Li Xin Machinery Limited. Linyi Public Li Xin Machinery Co. (www.lyzlx.com) is specialized in the "steel castings, cast steel, heat-resistant steel, ordinary steel castings" of the enterprise, the company adhering to the "honesty, hard service" concept, for you provide the highest quality products and services. Welcome to inquire! Contact: Peng. Linyi Public Li Xin Machinery Co., Ltd. located in Junan County Economic and Technological Development Zone, located in the southeast of Shandong Province Rusu junction, is the design, production, processing, marketing as one of modern science and technology enterprises, the use of advanced international cast today Process (EPC) a negative real casting process, production and more material high temperature, corrosion, abrasion, oxidation resistance alloy steel castings. Solution casting shrinkage defects in castings slipway, the most fundamental focus is the "thermal equilibrium." The methods are: (1) in the thickest section of the machine tool castings and thermal structure formation, the implementation of the rapid solidification, artificially basic balance throughout the machine tool castings temperature field. Inside and outside the cold iron, partial use of heat storage capacity of zircon sand, chromite sand or special coatings. (2) reasonable process design. Runner located in Pu wall opposite the casting machine, and distributed multi hours. So the first to enter the thick of the lead solidified molten metal, solidified thin-walled office to enable them around fundamental equilibrium solidification. Casting machine for uniform wall thickness, using a plurality of inner runner and vents. Multi-runner casting, casting dispersion and uniform gate valve, so that the overall heat balance. Fine and more vents that exhaust unobstructed underway cooling effect. (3) changes in the position of runner Linyi Public Li Xin Machinery Co., Ltd. located in Junan County Economic and Technological Development Zone of steel castings, located in Shandong Province in southeastern Rusu junction, is the design, production, processing and sales of Modern science and technology enterprises, using today's advanced casting (EPC) a negative real casting process to produce more material high temperature resistance, corrosion resistance, wear resistance, oxidation resistance alloy steel castings. Investment casting, also known as "casting" or "lost wax casting" and "cast" can be very extensive melting of the material, but also the shape of the complex structure of the product is not restricted. The most important feature is its size control precision, machining cutting margin rarely, smooth surface, with the gradual introduction of new advanced equipment and technology, the scope of which can be applied more widely. In the field of thermal processing, drawing hard or difficult pieces molded parts as well as some high processing costs of forgings, investment casting applicable; and in the field of casting, investment casting, some products can be used to replace other forms of casting, reduce processing cutting allowance to reduce costs and improve the dimensional accuracy and surface roughness and mechanical properties of the material, so as to achieve the purpose of upgrading product quality.
