--The die-casting production cycle is short, suitable for medium and large batch manufacturing of thousands to hundreds of thousands of pieces;
--Long mold life, unit cost significantly reduced with the increase of batch.
--Achieve dimensional accuracy of ±0.05mm;
--High repeatability, strong consistency of molded parts, suitable for assembly and batch assembly.
--Aluminum alloy: light weight, high strength, corrosion resistance, excellent thermal conductivity;
--Zinc alloy: high density, suitable for high-strength small parts.
--The surface of aluminum alloy die-castings can be anodized, sandblasted, painted, and laser engraved;
--Zinc alloy parts support decorative treatments such as electroplating, baking varnish, UV, and high-gloss polishing.
Standard production process
1. The engineering team conducts drawing review and structural evaluation, and issues DFM analysis according to 3D drawings;
2. Customize molds according to product structure, including mold frame, core, and cooling system design;
3. Use high-pressure die-casting machine to inject molten metal for die-casting, Short molding time, high precision, and excellent strength consistency;
4. If there are high-precision holes, threads, and tolerance surfaces, perform CNC secondary finishing or tapping;
5. Aluminum parts support anodizing, electrophoresis, spraying, sandblasting, and laser engraving; Zinc parts support electroplating (nickel/ chromium/ gold color, etc.), PU coating, and polishing;
