Casting Process

1. WAX INJECTION

  1. 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.

  2. Wax Injection: Inject the wax to form the patterns. Carefully remove the wax patterns from the mold.

  3. Cooling & Inspection: Submerge the patterns in cold water to prevent melting or deformation. Perform a 100% visual inspection of all wax patterns.

  4. Assembly: Weld the wax patterns onto a central sprue (tree) and hang the assemblies onto racks/trolleys.

2. SHELL MOLDING PROCESS (DIPPING)

  1. Slurry Dipping

  2. Stucco Coating / Sanding

  3. Shell Drying

3. WAX RECOVERY PROCESS (DEWAXING)

  1. Loading: Place the shell assemblies into the steam autoclave.

  2. Sealing: Securely close the autoclave door.

  3. Safety Lock: Engage the safety interlocking system.

  4. Alert: The alarm sounds upon cycle completion.

  5. Recovery: The recovered wax is channeled to the holding tank and pumped back to the wax injection machines

4. MOLD FIRING PROCESS

  1. Mold Preparation: Prepare the ceramic shells for firing.

  2. Loading: Place the molds into the furnace once the temperature reaches 1000–1250°C.

  3. Firing: Fire the molds at 1000–1250°C for a duration of 35–60 minutes.

  4. Unloading: Remove the molds from the furnace upon completion of the firing cycle

5. METAL POURING PROCESS

  1. Pouring: Pour the molten metal into the preheated molds.

  2. Melting: Melting time is approximately 40 minutes at a standard temperature of 1580–1600°C.

  3. Cooling: Place the casted molds on sand trays for cooling.

6. SHELL REMOVAL PROCESS (KNOCK-OUT)

  1. Preparation: Prepare the casted assemblies for shell removal.

  2. Shell Knock-out: Load the assemblies into the shell removal machine.

  3. Post-Removal Processing: Clean the components after the ceramic shell has been removed.

  4. Final Collection: Complete products are sorted and staged for individual part separation.

7. SHOT BLASTING PROCESS (VERTICAL & HORIZONTAL)

  1. Loading: Hang the components onto the machine hangers.

  2. Vertical Shot Blasting: Components are suspended for vertical blasting.

  3. Vertical Blasting Completion: Components are inspected after the first blasting cycle.

  4. Horizontal Shot Blasting: Components are moved to the horizontal blasting machine for final processing.

  5. Final Completion: Finished components after the horizontal blasting stage.

8. PART SEPARATION PROCESS

  1. Individual Separation: Separate each component from the sprue/tree.

  2. Transfer: Move components to the grinding and finishing stage.

9. SURFACE TREATMENT PROCESS

  1. Preparation: Organize components for the grinding stage.

  2. Precision Grinding: Individually grind and smooth the gate/cut-off points.

  3. Finished Treatment: Completed components after surface processing.

10. CLEANING & PICKLING PROCESS

  1. Loading: Place components into the rotating drum/barrel.

  2. Acid Pickling: Submerge and treat in the acid bath.

  3. Unloading: Transfer the components into collection baskets.

  4. Rinsing: Spray with clean water to remove chemical residues.

  5. Drying: Thoroughly dry the components.
