Bespoke castings since 1862

The fundamentals of the manufacturing process remain unchanged despite recent investments in the Foundry.

Silica sand mixed with sodium silicate is used to make the moulds for Castings and hardened off with carbon dioxide. The surface of the mould is treated to prevent sand binding to the casting and enhance the surface finish. The running, gating and filtering systems used are designed minimise the inclusions and porosity.

We operate 2 Induction Furnaces, each with a capacity of 120kg. Using a Holding Ladle we can combine the melts from both Furnaces to give a maximum capacity of 240kg, allowing for the running system this equates to a maximum casting size of 200kg.

Castings are fettled, and where required shot-blasted, prior to despatch.
