Precision Casting Parts

GooCasting® specializes in custom precision casting (investment casting) parts for aerospace, automotive, medical, and machinery industries. Our advanced investment casting process produces high-precision components with excellent surface finish and tight tolerances.

What is Precision Casting?

Precision casting, also known as investment casting or lost-wax casting, is a manufacturing process that produces metal parts with high dimensional accuracy and superior surface finish. The process involves creating a wax pattern, coating it with ceramic shell, melting out the wax, and pouring molten metal into the cavity.

Our Precision Casting Capabilities

• Materials: Stainless Steel (304, 316, 17-4PH), Carbon Steel, Alloy Steel, Aluminum Alloy, Copper Alloy, Superalloy
• Weight Range: 10g to 50kg
• Tolerance: CT4-CT6 (ISO 8062)
• Surface Finish: Ra 1.6-6.3 μm (as-cast)
• Minimum Wall Thickness: 2mm
• Production Capacity: 100 tons/month

Advantages of Precision Casting

• High Precision: CT4-CT6 tolerance, minimal machining required
• Excellent Surface Finish: Ra 1.6-6.3 μm reduces post-processing
• Complex Geometries: Intricate shapes, thin walls, undercuts
• Wide Material Range: Stainless steel, aluminum, superalloys, etc.
• Cost-Effective: Near-net shape reduces material waste and machining
• Consistent Quality: Repeatable process for high-volume production

Our Precision Casting Process

1. Pattern Injection: Wax patterns injected into aluminum molds
2. Cluster Assembly: Multiple patterns assembled on wax tree
3. Ceramic Shell: Tree dipped in ceramic slurry and stuccoed
4. Dewaxing: Shell heated to melt out wax patterns
5. Shell Firing: Shell fired at high temperature for strength
6. Metal Pouring: Molten metal poured into preheated shell
7. Cooling & Shell Removal: Casting cooled, ceramic shell broken off
8. Cut-off & Finishing: Parts cut from tree, gates removed
9. Quality Inspection: Dimensional check, X-ray, pressure testing
10. Post-Processing: Heat treatment, machining, surface finishing if required
