Metal casting aluminum gravity die casting base

Product Description

Gravity die casting

In gravity die casting molten aluminium is poured into a metallic tool. The casting temperature is about 750°C. The tolerances and surface finish are good. The use of sand cores in gravity die casting enables casting of very complex components.

Gravity die casting method is competitive casting method when production quantity is relatively small or when heat treatment is needed to improve the mechanical properties. This casting method gives better tolerances and surface finish than sand casting. The tooling costs are somewhat higher than by sand casting.

Main Features

Good dimensional accuracy

Smoother cast surface finish than sand casting

Improved mechanical properties compared to sand casting

Thinner walls can be cast compared to sand casting

Reverse draft internal pockets and forms can be cast in using preformed sand core inserts

Steel pins and inserts can be cast in to the part

Faster production times compared to other processes.

Once the tolling is proven, the product quality is very repeatable.

Outsourced Tooling setup costs can be lower than UK sand casting.
