Many machine components are made from aluminum. When you buy
these parts from the manufacturer they are invariably expensive (and on back order). Aluminum die casting is a relatively simple process requiring commonly available materials like a gas burner, sand / clay for molds and scrap aluminum. Cost : $100 for gas burner & tank. Higher quality products can be obtained using special molding materials, a crucible and pure aluminum ingots. These are usually available in national capitals. Total cost : less than $400. |
