Aluminum Sand Casting Part

Aluminum sand casting production technology process: Production plan → Sand mixing → Mould making → Modeling → Drying → Smelting → Pouring → Cooling → Open → Shakeout → Gas cutting → Polish → Repair welding → Checkout The precision of the Aluminum sand casting: ±1mm~ Smoothness of surface of rough part: Ra6.4; Shrinkage rate of aluminum sand casting products: 2%; Material wastage rate: 7%; General aluminum sand casting machining allowance: 2mm~3mm; Surface preparation methods: Sand blasted, Shot blasting, Powder coating, Painting, Plating, Electrophoresis, Polishing. Advantages and disadvantages of aluminum sand casting part: Generally use wooden and aluminum mold, far cheaper than metal mold casting mould. The price advantage is particularly prominent in small batch and bulk production. But the production efficiency is low; Low dimension accuracy of castings, the surface is rough.
