ADC12 New Energy Storage Battery Pack End Plate - ESS Parts from China Suppliers and Factory
Aluminum die casting
Material: A380
- Furnace temperature: 670°±20°, Material handle: 20±2MM;
- Secondary materials cannot be used;
- Test the material composition to confirm that it is OK and can be produced;
- First piece confirmation is required after die-casting.
- The filling quality of the surface needs to be confirmed. No cold insulation, no bulging, or lack of material for the pillars.
- Pay attention to the surface to avoid sticking molds, drawing molds, or poor ejector pin convexity.
- 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.
Remove spout (Saw spout and knock out slag bag)
- Pay attention to the surface without crushing or shortage of materials.
- Control the appearance and size.

Frequently Asked Questions (FAQ)
We use high-grade A380 aluminum alloy processed on a 280T aluminum die casting machine. The furnace temperature is strictly maintained at 670°±20° with a material handle requirement of 20±2MM.
For CNC machining (including tapping of 2 through holes for M3 teeth), operators must verify that there is no over-cutting, missing processing, surface scratches, or burrs. We also guarantee strict dimensional and form tolerances during this stage.
Laser engraving is performed on two O-port location planes. The engraved area must be completely clean, free from oil or black marks, and the edges of the O-shaped orifice must not contain any burrs, particles, or aluminum chips.
To prevent scratches, dents, and surface dirt, products are placed in a customized knife card/blister tray, covered with flat cardboard or white rice paper, and securely packed into cartons using bubble bags.
We perform FQC and OQC inspections using calibrated measuring tools (caliper, projection, needle gauge, tooth gauge). We verify compliance with SIP and customer requirements, match the shipping quantity to the order, label/stamp the outer box, and provide a detailed shipping report.
