Expertise in High-Performance Molding
From Design to Production
Vacuum casting begins with master model preparation, followed by silicone mold creation, polyurethane resin pouring, and vacuum degassing. After curing, parts undergo demolding and finishing for final production-ready components.
From Design to Production
The die-casting process begins with mold design and CNC machining of steel dies. Molten alloy is injected under high pressure, rapidly cooled, and ejected. Post-casting steps include trimming, deburring, and surface finishing for precision metal components.
Price Evaluation & Negotiation
Receive and review customer part drawings, clarify project requirement, and price negotiation.
Design Analysis
Conduct DFM and mold flow analysis to identify design issues and improve manufacturability.
Mold Design
Design parting surfaces, structure and injection systems based on requirements and analysis results.
Mold Making
Use milling, turning, and EDM to produce all mold components accurately.
Mold Assembly
Assemble all components with proper alignment and precision adjustments.
Mold Trial
Perform mold trials and inspect T1 samples to verify mold function and quality.
Mold Tuning
Modify mold based on feedback and testing results, confirm performance and apply surface finish.
Production Run
Production of alloy components using die-casting molds.
