Investment Casting Process is also known as lost wax casting, including waxing, grouping, dipping, melting wax, casting molten metal and post-treatment. Lost wax casting is a wax mold in which a part is to be cast with wax, and then the wax mold is coated with mud, which is a mud mold. After the mud mold is dried, the internal wax mold is melted by placing it in hot water. The mud mold from which the wax mold has been melted is taken out and baked into a ceramic mold. Once roasted. In the general clay mold, the pouring port is left, and the molten metal is poured from the pouring port. After cooling, the required parts are prepared.

Parameter

1. Casting classification: Sand casting; Precision casting; Vacuum process casting etc.

2. Gray iron, ductile iron, alloy steel,alumium,etc.

3. Adoption standard: BS, DIN, ASTM GB etc.

Features

The Investment Casting Process product features variable wall thickness and requires tighter tolerances. This type of process has fewer steps from raw materials to finished products, and has a fast production cycle, which not only reduces material waste, but also has a long tool life.

Investment Casting Process castings are generally more complex in shape, with a minimum diameter of 0.5 mm for casting holes and a minimum wall thickness of 0.3 mm for castings. In the production, some parts that were originally composed of several parts can be directly cast by investment casting by changing the structure of the parts and designed as an integral part. This can save the processing time and the consumption of metal materials, so that the part structure is more reasonable.
