Process
1, Aluminum die casting
Equipment & Material
Equipment: 280T aluminum die casting machine, Material: A380
Process characteristics
- a. Furnace temperature: 670°±20°, Material handle: 20±2MM;
- b. Secondary materials cannot be used;
- c. Test the material composition to confirm that it is OK and can be produced;
- d. First piece confirmation is required after die-casting.
Precautions
- a. The filling quality of the surface needs to be confirmed. No cold insulation, no bulging, or lack of material for the pillars.
- b. Pay attention to the surface to avoid sticking molds, drawing molds, or poor ejector pin convexity.
- c. The ejector pins are concave by 0-0.2mm for non-machine-added surfaces and 0-0.2mm for machine-added surfaces. The thimble needs to be convex 0-0.2mm.

Frequently Asked Questions (FAQ)
Q1: What materials and machinery are used in your aluminum die casting process?
A1: We utilize high-quality A380 aluminum material processed through a robust 280T aluminum die casting machine. This ensures high structural integrity and dimensional consistency for all produced parts.
Q2: How do you guarantee the quality of CNC machined parts?
A2: We implement strict IPQC and FQC inspections, verify dimensions using calipers, projection systems, and tooth gauges, and ensure there is no over-cutting, scratching, or burrs left on the surface.
Q3: What precautions are taken during the laser engraving process?
A3: During laser engraving of the O-port location planes, we verify that no burrs, particles, or aluminum chips remain on the edges. The engraved surface must be clean and entirely free of oil and black marks.
Q4: How are the finished products packaged for shipping?
A4: Products are carefully placed inside blister trays or custom knife cards, protected with white rice paper or flat cardboard dividers, and then securely boxed in cartons with bubble bags to prevent any damage during transit.
Q5: What inspection steps are performed before the products are shipped?
A5: We conduct a 100% visual appearance inspection, FQC inspection, and a final OQC shipping inspection to verify that the quantities match the order, labels are correct, and all specifications meet customer requirements.
