1.Manufacturing of injection mould

Create the original model by casting the parts. The model outlines the casting

2.Wax injection molding

Pour the wax into the mould and shake it around until the inner surface of the mould is covered with a uniform coating, which requires precise coordination between the injection pressure of the machine and the temperature of the wax to ensure higher dimensional accuracy and surface quality

3.Assembly of wax models

Multiple wax moulds can be created and assembled to form a wax tree for casting in a batch casting. Experienced staff carefully assembled to ensure that the casting parts of high quality

4.Impregnation, sandblasting, drying

The wax tree is repeatedly dipped into a ceramic sauce, coated with sand and dried to form a ceramic shell

5.Dewaxing

After the ceramic mold is fully cured, it is turned over and placed in a furnace or autoclave to melt and/or evaporate

6.firing

The die is then burned, heated to between 870 ° C and 1095 ° C to remove any moisture and residual wax, and the die is sintered

7.casting

The customer-specific alloy constituents required for each casting batch are compiled and melted in our induction furnace. The molten metal is then poured into the hot ceramic mould using a pouring ladle. The precise temperature control of the molten steel, pouring ladle and ceramic moulds assures the high material quality and surface finish even for thinwalled components with complex geometries.

8.Demoulding

Once the cluster has cooled, the ceramic shell is carefully removed.

9.separating

The casting is separated from the runner.

10.shot blasting

Any ceramic residues are removed from the surface of the castings in a blasting process.

Finally, they are polished, heat treated, dressed, machined and/or surface coated as required by the customer.

11.final inspection

Optical inspection of 100% of all investment casting products. The full set of standards and measures used in quality control are coordinated with customers according to their specific requirements.
