Precision steel mechanical parts

Precision steel machinery parts precision casting precision casting process design include: precision casting, precision stainless steel castings and precision castings. Precision casting process design: First, we make the three-dimensional shape of the product according to samples or drawings, with this three-dimensional map production of aluminum or steel molds. News detailed precision castings include: precision casting, precision stainless steel castings and precision castings. Here I plant to introduce precision casting process design: we design according to customers samples or drawings mold design CAE simulation pouring casting systems software. Tooling: We make three-dimensional modeling products based on samples or drawings, with this three-dimensional map production of aluminum or steel molds. NOTE wax: the liquid wax and solid wax mixing into a burnt-like paste wax, wax injection gun with paste wax injected into the mold after it has cooled remove the wax. Wax piece assembly: heating stainless steel welding knife, the wax in the press gate stick welding process design requirements. Sticky pulp: the wax cylinders immersion member group comprising water glass coating, the coated paint. After completion of the coated paint pouring wax member group of quartz sand, and then immersed in the hardening bath containing ammonium chloride and magnesium chloride and other hardening material was dried, and then the next level of operation, this process is repeated about six times: pouring sand . Dewaxing: The surface coating of the hardened wax member group placed in the lost wax bath, with steam heated to dissolve the wax off, the remaining shell sand mold. Firing the shell mold: placing the mold shell fired roaster to increase its strength. Casting: The molten material into the electric furnace, adding a metal-free vegetarian recipes were material, the temperature rose to about 1600 degree molten steel, chemical analysis of blast furnace melting qualified after ladle of molten steel poured into the mold through the shell, so steel fluid filled cavity and then cooled, and sampled after final inspection done furnace. In addition to housing: the casting surface of the sand by removing vibration method. Cutting: oxygen - acetylene flame pouring from the cut rod casting. Polished: The grinder mill except Riser; grinder grinding with poor surface. Heat treatment: Casting Material requirements normalizing, annealing, quenching and tempering, induction hardening, carburizing, nitriding and other heat treatment. Machining: the processing performed by drawing with CNC. Final inspection: The tensile testing machine, impact testing machines, hardness and other testing equipment to test rods for testing the mechanical properties; with X-ray, ultrasound, magnetic particle testing and other testing equipment for non-destructive testing sample; and with coordinate measuring tools and calipers and other gage final inspection of the product size. Package sent: qualified product surface rust treatment done after loading glued wooden box or tin trunk after shipment.
