- Die manufacturing : A negative replica of the component is prepared in the form of metallic die.
|
- Disposable wax pattern is proced by injecting wax from PLC controlled horizontal wax injection machines in the semi automatic, water circulated Die(Tool).
|
- Produced Wax pattern from single or multicavity die(tool) are then assembled to form a tree structure having feeding gate,runners, & sprue.
|
- Sucessive coats of ceramic slurries & refractory sand are applied with intermediate drying time to form a shell.
|
- Wax pattern invested in "shell" is melted out by applying heat sourse during de-waxing stage to form a hollow shell.
|
- The specified molten metal is poured in the hot baked hollow shell.
|
- Upon cooling the precision castings are achieved after usual operations like gate removal, cleaning,etc &subjected to further processing such as heat treatement,surface treatement etc.
