Casting Machining

. Description Sand casting refers to a casting method in which castings are produced in sand molds. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting methods. The basic raw materials for making sand molds are foundry sand and sand binder. The most commonly used foundry sand is siliceous sand. When the high-temperature performance of silica sand cannot meet the requirements

42CrMo Steel Auto Harmonic balancer puller Silica sol casting. Description In silica sol casting, the pattern is made by wax and other easily soluble materials, and several layers of refractory materials are coated on the pattern to complete the shell. The pattern is formed by melting and casting, and then it is subjected to high temperature baking to achieve better application effects. Casting belongs to the category of near-net shape technology, which can produce high

. Description Investment casting, also known as lost wax casting, includes processes such as pressing wax, repairing wax, assembling trees, dipping slurry, melting wax, casting molten metal, and post-treatment. Lost wax casting is to use wax to make a wax mold of the part to be cast, and then coat the wax mold with mud, which is a mud mold. After the clay mold is dried, put it in hot water to melt the internal

A380 Aluminium with PVD coating Gravity die casting and Machining parts. Description Gravity casting refers to the process of injecting molten metal into a mold under the action of the earth's gravity, also known as gravity casting. The generalized gravity casting includes sand casting, metal casting, investment casting, lost foam casting, mud casting, etc. The narrow gravity casting mainly refers to metal casting. PVD (Physical Vapor Deposition) coating technology is mainly

Description Zinc alloys are alloys based on zinc added with other elements. Commonly added alloying elements include aluminum, copper, magnesium, cadmium, lead, and titanium. Zinc alloy has low melting point, good fluidity, easy to weld, braze, and plastic processing. It is corrosion resistant in the atmosphere. The residual material is easy to recycle and remelt. However, its creep strength is low

. Description The traditional die-casting process is mainly composed of four steps, or it is called high-pressure die-casting. These four steps include mold preparation, filling, injection, and sand falling, which are also the basis for various improved die casting processes. During the preparation process, a lubricant needs to be sprayed into the mold cavity. In addition to helping to control the
