Through our Companies commitment and engineering knowledge, we are positioned to be our customers trusted business partner.


Castle have their own anodising plant readily available for use across all components that require an anodising finish standard.

This type of integration not only makes the control of materials easier, but offers customers reduced turnaround times and cost reduction opportunitites. Anodising traditionally is a 3rd party process where minimum charges can increase the cost of components considerably or be hidden in within finishing cost buckets that do not give the customer true cost transparency of the component. 

We aim to deliver complete products with no additional 3rd party process required after receipt from us, with the cost of anodising built into our finished component price.
