Casting Process
1. WAX INJECTION
-
Mold Preparation: Prepare the molds according to the customer’s specific part numbers. Ensure all mold components are perfectly aligned and interlocked before placing them into the injection machine.
-
Wax Injection: Inject the wax to form the patterns. Carefully remove the wax patterns from the mold.
-
Cooling & Inspection: Submerge the patterns in cold water to prevent melting or deformation. Perform a 100% visual inspection of all wax patterns.
-
Assembly: Weld the wax patterns onto a central sprue (tree) and hang the assemblies onto racks/trolleys.

2. SHELL MOLDING PROCESS (DIPPING)

-
Slurry Dipping
-
Stucco Coating / Sanding
-
Shell Drying
3. WAX RECOVERY PROCESS (DEWAXING)
-
Loading: Place the shell assemblies into the steam autoclave.
-
Sealing: Securely close the autoclave door.
-
Safety Lock: Engage the safety interlocking system.
-
Alert: The alarm sounds upon cycle completion.
-
Recovery: The recovered wax is channeled to the holding tank and pumped back to the wax injection machines

4. MOLD FIRING PROCESS

-
Mold Preparation: Prepare the ceramic shells for firing.
-
Loading: Place the molds into the furnace once the temperature reaches 1000–1250°C.
-
Firing: Fire the molds at 1000–1250°C for a duration of 35–60 minutes.
-
Unloading: Remove the molds from the furnace upon completion of the firing cycle
5. METAL POURING PROCESS
-
Pouring: Pour the molten metal into the preheated molds.
-
Melting: Melting time is approximately 40 minutes at a standard temperature of 1580–1600°C.
-
Cooling: Place the casted molds on sand trays for cooling.

6. SHELL REMOVAL PROCESS (KNOCK-OUT)

-
Preparation: Prepare the casted assemblies for shell removal.
-
Shell Knock-out: Load the assemblies into the shell removal machine.
-
Post-Removal Processing: Clean the components after the ceramic shell has been removed.
-
Final Collection: Complete products are sorted and staged for individual part separation.
7. SHOT BLASTING PROCESS (VERTICAL & HORIZONTAL)
-
Loading: Hang the components onto the machine hangers.
-
Vertical Shot Blasting: Components are suspended for vertical blasting.
-
Vertical Blasting Completion: Components are inspected after the first blasting cycle.
-
Horizontal Shot Blasting: Components are moved to the horizontal blasting machine for final processing.
-
Final Completion: Finished components after the horizontal blasting stage.

8. PART SEPARATION PROCESS

-
Individual Separation: Separate each component from the sprue/tree.
-
Transfer: Move components to the grinding and finishing stage.
9. SURFACE TREATMENT PROCESS
-
Preparation: Organize components for the grinding stage.
-
Precision Grinding: Individually grind and smooth the gate/cut-off points.
-
Finished Treatment: Completed components after surface processing.

10. CLEANING & PICKLING PROCESS

-
Loading: Place components into the rotating drum/barrel.
-
Acid Pickling: Submerge and treat in the acid bath.
-
Unloading: Transfer the components into collection baskets.
-
Rinsing: Spray with clean water to remove chemical residues.
-
Drying: Thoroughly dry the components.
