Die Casting

Precision Die Casting Manufacturing, Honoring Classic Craftsmanship

Mature Expertise Full-Process Control Multi-Material Mastery

Die casting utilizes high-pressure injection of molten metals (aluminum/zinc alloys) into steel molds, enabling mass production of precision components with complex geometries.Delivering dimensional stability and superior surface finish , it minimizes post-processing.

Core Manufacturing Process

Melting & Die Casting

Aluminum alloys: 660 - 720°C melting + standard die casting (60-100MPa pressure)

Zinc alloys: 380 - 420°C melting + high-fluidity die casting Magnesium alloys: Flame-retardant melting (SO2 gas shielding)

Quality: Vision inspection (burrs/overburn)、CMM sampling for critical dimensions

Machining Technical Parameters

CNC machining centers (FANUC/Brother systems): Positioning accuracy ±0.01mm

Key operations: Milling, drilling/tapping, cylindrical turning

Surface Finishing

Painting: Primer + topcoat + UV curing (500h salt spray resistance) | Materials: Al/Mg alloy housings

Electroplating: Zn alloy Ni/Cr plating (mirror finish) | Al alloy anodizing (15-25μm thickness)shielding

Quality Assurance

Key Inspection Criteria:

Dimensional Tolerance of Molded Parts（±0.05mm）；Internal Porosity（X-ray inspection）；Material Impact Resistance

Testing Equipment:

Industrial CT Scanner（3D reconstruction of internal defects）；Melt Flow Indexer（Material consistency verification）；Thermal Shock Chamber（Extreme temperature cycling tests）
