Raw materials such as metal, ceramic & wax are purchased from our qualified suppliers.All raw material are inspected by incoming quality control department for material composition analysis.
Tooling die can be supplied by our customers or produced by our experienced tooling technicians who make use of computerized machinery to achieved the best measurement of specification.
Mold Design
Hot wax is injected into an aluminum mould to create a wax pattern.
Injection of wax pattern inside metal mould
Wax patterns are removed from the die and assembled on a wax runner.
Assembly of clusters
Assembled wax patterns are dipped into ceramic slurry. Drained then coated with fined sand.
Covering the cluster with refractory mud
After drying this process in repeated up to 8 times. Once the ceramic shell mold'sdry.
Covering the cluster with granular refractory material
The wax is taken away from ceramic shell by an autoclave and most of the wax is melted out during this process.
Elimination of wax by means of pressure and heat
The ceramic shell is then preheated up to 1300 °C before filling with melted metal alloy. The remaining wax is completely combusted during this process.
High temperature cachinnation of the ceramic mold
Chemical compositionwill an alysisby spectrometer, all chemical composistion will be guarantee according to the material standard.
Material analysis
The shell is then pouring an cast in the desired alloy. Poured molds are settled to cooling for a specified minimum time.
Filling the ceramic mould with metal
The remaining ceramic is removed from the metal and blasting. tumbling or other chemical cleaning process.
Removal the refractory material
Separation of cluster parts by cutting
Sandpapering the on let channel
The parts are then carefully inspected for correct tolerance and shipped.
