Step 1. MOLD DESIGN
- The mold will be designed by our engineer. The mold will be purchased from a mold factory.
Step 2. WAX INJECTION
- Injection molding produces wax designs for the desired castings. This process is called patterns.
Step 3 . ASSEMBLY TREE
- Casting clusters or assembly trees are formed by attaching patterns to a central wax stick, called a sprue.
Step 4. SHELL MAKING
- To build the shell, the assembly is immersed in a liquid ceramic slurry and then in a bed of extremely fine sand. Up to SEVEN layers can be applied in this manner.
Step 5. DEWAX
- When the ceramic is dry, the wax will be melted. The melted wax will flow out.
Step 6. CASTING
- During the conventional process, the shell is filled with molten metal by gravity pouring, which cools into solid parts, gates, sprues, and pouring cups.
Step 7. KNOCKOUT
- The ceramic shell will be broken off by vibration or a knock-out machine after the metal has cooled and solidified.
Step 8. CUT OFF
- A high-speed friction saw is used to cut away the parts from the central spruce.
Step 9. GRINDING
- The casting pouring part will be ground carefully after the casting has been cut off.
Step 10.Inspection and Post Treatment.
- Inspectors will inspect the casting according to the drawing and quality request. Unqualified parts will be repaired and inspected again if necessary.
Step 11. FINISHED CASTINGS
- The metal castings are ready for shipment after surface finishing operations making them identical to the original wax patterns.
