Low pressure aluminum injection molding

EMP also utilizes a 75KW melt unit for a low-pressure aluminum injection molding machine. This process is well suited to products with requirements for ductility in up to a 20-inch diameter.  Steel or iron injection tooling is used, with normal casting weights of 1 to 20 pounds. The combination of competitive Mexico labor rates and efficient machinery makes the investment in high production casting tooling worthwhile.

Parts up to 20 inches in diameter
Weights up to 20 pounds
Excellent mechanical properties
Not suitable for small parts with fine detail, since pressure is limited to 16 psi
Tooling is typically made of iron or tool steel, requiring significant annual production quantities to amortize the cost of the dies.
