Process
Step 01
Aluminum die casting
Material: ADC12
Equipment: 1250T aluminum die-casting machine
Process characteristics:
a. Material handle: 20±2mm, furnace temperature: 670°±20°
b. The use of secondary items is not allowed
c. Verify through testing that the material composition is suitable and can be manufactured
d. After die casting, first piece confirmation is required
Preventive measures:
a. Verify the filling quality of the surface. It’s not the bulge, it’s not the cold insulation, it’s not the lack of material in the pillars.
b. Pay attention to the surface to prevent poor ejector pin crown, mold pulling or mold sticking.
c. For non-machined surfaces and machined surfaces, the ejector pins are concave by 0-0.2 mm. The ejector pin must have a 0-0.2 mm convex shape.

Tools: CNC machine tools, drill bits, tap processing fixtures, flat bottom milling cutters.
B. Burr: To achieve a smooth appearance, the product's sharp corners are chamfered, deburred, and non-machined ejector pins are sharpened and polished.
Tools: sandpaper (120#), wind grinder, file.
Tools: sandpaper (120#), wind grinder, file.
C. Appearance visual assessment and 100% material inspection.
Precautions:
a. Avoid over-cutting or improper processing;
b. Be careful not to produce burrs or damage the surface;
c. Verify that the treated surface has Ra0.8 polish and dimensional and shape tolerances. The R corners should be connected smoothly, no burrs or sharp corners should be removed, and no processing should be missed;
d. The surface of the product must be free of burrs, blisters, lack of material and other undesirable features;
e. Use the go gauge and stop gauge to detect;
f. Verify product flatness against design;
g. To avoid deformation, please handle with care.
