Ersa gearbox selector forks manufactured using investment casting


Aluminium tools are designed and manufactured in-house. These are used for investment casting.

A wax part is produced from the tool, this is shelled in ceramic and baked in an oven. The metal is then poured into the ceramic shell. When the metal cools, the ceramic is removed revealing a high quality, high definition part. This allows parts to be produced in high tensile steel. Examples are suspension components, steering arms, uprights and engine parts.
