Linyi Public Li Xin Machinery Co., Ltd. is 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 enterprise, the use of advanced international casting today Process (EPC) a negative real casting process, production multi-material high temperature, corrosion, abrasion, oxidation alloy steel castings. Castings for internal defects, commonly used non-destructive testing methods are ray inspection and ultrasonic testing. Wherein said radiation detecting best purchasing machine tool castings, it is possible to obtain reflected internal defect types, shape, size and distribution of the visual image, but for large castings large thickness, ultrasonic testing is very effective, can be more accurately measured internal position of the defect, the size and distribution of equivalents. Linyi Public Li Xin Machinery Co., Ltd. is the design, production, processing, marketing as one of modern science and technology enterprise, the use of advanced international casting today (EPC) of a negative real casting process to produce more material temperature resistance corrosion, abrasion, oxidation alloy steel castings castings procurement, including heat-resistant steel castings, alloy steel castings, wear-resistant steel castings, corrosion casting, heat treatment of castings. In the casting process, the casting process of designing a great impact on the quality of the procurement bed casting foundry products, but the choice of selection method of gating system can not be ignored. Feeding system design is reasonable design riser and subsidies to compensate for the casting liquid produced during solidification and solidification shrinkage state, in order to obtain a sound engineering technology casting [1]. Cavity vent for discharging a gas, liquid metal to improve the filling ability, to exclude first charged into the cavities subcooled liquid metal and dross, may mark an observation cavity is poured full of [1]. _ Public Procurement body castings Li Xin casting company E (certified) _ Casting Linyi Public Procurement by Li Xin Machinery Limited.
