Alloy castings manufacturers _ Public Li Xin casting company (certified) _ casting factory provided by Li Xin Machinery Co., Ltd. Linyi congregation. 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 precision castings manufacturers, producing more material high temperature resistance, corrosion resistance, wear resistance, oxidation resistance alloy steel castings. The products are widely used in metallurgy, mining, chemicals, shipbuilding, paper, machinery, military and other industries. Production process and quality in a leading position, with metal spectrometer, and other advanced detection equipment. The company can design according to user needs, manufacturing a variety of standard and non-standard special foundry products. In the machinery and equipment in a large proportion of liquid molded parts, machine tools, internal combustion engines, mining machinery, heavy machinery in liquid molding pieces 70% to 90% by weight of the total; 50% to 70% in cars, tractors; and in Agricultural machinery accounted for 40% to 70%. Liquid molding process can be so widely used, because it has the following advantages: (1) can be manufactured lumen rough shape very complicated. Such as various cabinet, machine bed, cylinder block, cylinder head and so on. (2) process flexibility, wide adaptability. The size of the liquid molding parts manufacturer virtually unlimited castings, its weight by a few grams to several hundred tons, and its wall thickness by about 0.5mm to 1m. The industry who can melt into liquid metal material can be used for liquid molding. For poor ductility of cast iron, is the only liquid molding process for producing blanks or parts thereof. (3) lower cost liquid molding member. Direct use of waste liquid molding parts and chips, lower equipment costs. Meanwhile, the liquid molding pieces small allowance, saving metal. Shandong Linyi Public Li Xin Machinery Co., Ltd. is a set design, production, processing, marketing as one of modern science and technology enterprise valve castings manufacturers, the use of advanced international casting today (EPC) of a negative real casting process, the production of multi-resistant material high temperature resistance, corrosion resistance, wear resistance, oxidation resistance alloy steel castings, including heat-resistant steel castings, alloy steel castings, wear-resistant steel castings, corrosion resistant castings, heat treatment castings. Casting due to a variety of factors affect the mechanical castings manufacturers, often there will be holes, pinholes, slag, cracks, dents and other defects. Repair equipment commonly used for welding machines, resistance welding machines, cold welding and the like. For less demanding quality and appearance of the casting defects can be used welding machines and other heat capacity, speed welder to repair. But in the field of precision casting defect repair, due to the large argon welding heat affected will cause distortion when casting repair, reduce the hardness, trachoma, local annealing, cracks, pinholes, abrasion, scratching, biting edge, or a combination of force is not enough and the inner stress injury and other secondary defects. Cold welding just overcome the above disadvantages, its advantages mainly in the heat-affected zone is small, casting no warm, at room temperature cold welding repair, and therefore no distortion, undercut and residual stress, no local annealing, does not change the casting of metal organizational status. Thus surface defect cold welding for precision castings of repair.
