Precision castingThe method refers to the general term for forging methods that use non-metallic materials for casting molds, and the product size accuracy is higher than that of ordinary sand mold castings. It includes three categories: dewaxing casting method, plaster mold method and porcelain mold method.

Dewaxing casting methodFeatures and advantages

(1) The length of the larger boundary of the casting is700Mm,The strengths of Yi Zuo are200mmWithin. The larger net weight of the casting is about100Kilograms, usually10Within kilograms.

(2) Dimensional tolerance of castings20Mm±0.13Mm,100Mm±0.30mm,200mm±0.43Mm,The dimensional accuracy of small parts is not easy to achieve±0.10Mmwithin. The viewing angle tolerance is±0.5~±2.0Degree, the minimum thickness of the casting0.5~1.5Mm.The thickness of the surface of the casting is aboutRmax4sshop~12S.

(3)Cast off waxCasting materialhardlyLimited, such as aluminum alloy profiles, die-cast aluminum, titanium metal, alloy copper, various stainless steel plates, cobalt-based and nickel-based heat-resistant alloys, and hard raw materials.

(4) It can produce complicated-looking product workpieces, with excellent dimensional accuracy and less drilling and processing.

(5) Consumption of raw materials is saved, and many productions are possible. Dewaxing high-precision castings are widely used in spout engines, gas turbochargers, steam turbochargers, airport parts, gas turbines, cars, food machinery and equipment, printing equipment, paper machinery and equipment, refrigeration compressors, various valves, and help Pu, measuring instrument, electric sewing machine, weaponry, business management equipment, andOtherEquipment parts.
