Customized Precision casting steel 316/304

The production process of precision casting/investment casting/Lost wax casting:

1. Make molds according to different shapes of products. The mold is divided into upper and lower concave molds, and is completed through comprehensive processes such as turning, planing, milling, etching, and EDM. The shape and size of the pit are the same as the half of the product. Because wax molds are mainly used for industrial lost wax casting pressing, aluminum alloy materials with low melting point, low hardness, low requirements, low price and light weight are used as molds.

2. Use aluminum alloy molds to produce a large number of industrial wax solid core models. Under normal circumstances, an industrial wax solid core model can only correspond to one rough product.

3. Refine the margin around the wax mold. After deburring, stick a plurality of single wax molds on the pre-prepared mold head (also known as group tree). This mold head is also an industrial wax solid produced by the wax mold. core model. (looks like a tree)

4. Coat the multiple wax molds fixed on the die with industrial glue and spray the first layer of fine sand (a kind of refractory sand, high temperature resistance, usually silica sand) evenly. The grains of this sand are small and fine, which ensures that the surface of the final blank is as smooth as possible.
