Linyi Public Li Xin Machinery Co., Ltd. is the design, production, processing, marketing as one of modern science and technology enterprises, using today's advanced international casting (EPC) of a negative real casting process, the production of high temperature casting material more resistant casting corrosion, wear resistance castings, alloy steel castings and other antioxidant. Production process and quality in a leading position, with metal spectrometer, and other advanced detection equipment. EPC (also known as solid casting) is combined with casting wax or similar size and shape foam bonded to model cluster model, brushing refractory coating and after drying, dry quartz sand buried in the shape of vibration resistant steel castings In vacuum casting, so that the model gasification, liquid metal model position occupied, the new casting method after the formation of casting solidification cooling. Linyi Public Li Xin Machinery Co., Ltd. is the design, production, processing, marketing as one of modern science and technology enterprises, using today's advanced international casting (EPC) of a negative real casting process, the production of high temperature casting material more resistant casting corrosion, wear resistance castings, alloy steel castings and other antioxidant. Production process and quality in a leading position, with metal spectrometer, and other advanced detection equipment. A sand casting process: 1 sand sand mixed system → → modeling, core → close box 2 metal smelting area, getting fit ingredients → smelting → → pouring molten metal pouring cooling → → → fight me remove the casting casting cleaning and sampling Linyi Public Li Xin Machinery Co., Ltd. is the design, production, processing, marketing as one of modern science and technology enterprise resistant steel prices, using the current international advanced casting (EPC) a negative real casting process, the production of multi-resistant material high-temperature casting, casting corrosion, abrasion castings, alloy steel castings and other antioxidant. Production process and quality in a leading position, with metal spectrometer, and other advanced detection equipment. 3.2.3.1 fracture cast microstructure examination will cast off, visually or 5 times magnifying glass heat-resistant steel casting section with or without defects, when necessary, carry out X-ray fluoroscopy. 3.2.3.2 low magnification inspection does not exceed 20 times the magnifying glass sample section, mainly the internal pinholes, loose, slag, cold flow, crack, Q / ZX 12.203.3 - 2001 3 patterns and other defects. 3.2.3.3 high-power high-power microscopic examination of castings inspection within the organization, our products generally do not have this test, except for special needs.
