Process
1, High Pressure Aluminium alloy die cast:
Equipment: 350T cold chamber aluminium die casting machine,
Material: ADC12 (US-383/Russia-AJ16/ German-AlSi8Cu3/UK-LM2/Italy-4520/Eu-ENAC-46400)
Process Features
a. Furnace temperature: 650°±20°, Material handle: 20±2MM;
b. Secondary materials cannot be used;
c. Test the material composition to confirm that it is OK before be produced;
d. First piece confirmation is required.
Precautions:
a. Confirm the filling quality of the surface . 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.
2, Degating（Saw gate and knock out slag bag）
Equipment : Sawing machine
Tools: wooden stick
Precautions:
