Castech specialises in the hardsand process which involves blending sand, binder and catalyst together in a continuous mixer. The sand mixture sets hard over the pattern tooling which in turn creates a mould that is ready to pour. By using a finer grain sand, we are able to produce a superior finish to our castings.
The moulders take great care in the preparation and manufacture of the mould with every detail carefully inspected before casting. An accurate mould reqires less machining making it more viable and economical for the customer.
