Process
1
Aluminum 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)
What equipment and materials are used in the primary aluminum die casting stage?
We utilize a 280T aluminum die casting machine and A380 material. The process requires a strictly controlled furnace temperature of 670°±20° and a material handle of 20±2MM.
What surface quality defects are monitored during die casting and spout removal?
We inspect for filling quality issues, ensuring there is no cold insulation, no bulging, or lack of material for the pillars. During spout removal, we ensure the surfaces are free from crushing or material shortages.
What are the key requirements for CNC machining and laser engraving?
For CNC, we ensure no over-cutting, no missed processing, and prevent surface scratches while maintaining strict dimensional tolerances. For laser engraving, the location planes must be free of burrs, particles, and aluminum chips, with no oil or black mark contamination.
How are quality control inspections structured throughout the process?
Quality checks are integrated at multiple stages: IPQC inspections occur after spout removal, shaping, and laser engraving; a 100% visual inspection is performed before packaging; and final FQC and OQC shipping inspections guarantee compliance with SIP and customer requirements.
What packaging standards are used to protect the finished products?
We use protective packaging materials including blister trays, white rice paper, knife cards, flat cardboard, bubble bags, and cartons to ensure the surfaces remain free of dirt, scratches, dents, and defects during transit.
