To complete a production-ready tool the semi-finished castings require parting lines to be matched, surfaces prepared, frames clamps and special insert holders fitted.

In order to achieve precise parting lines the aluminium shells are stress relieved before matching together.

The moulding surfaces will be prepared according to the customers’ specifications. Common surface treatments ranging from sandblasting and/or shotpeining for which we have set up dedicated blasting chambers, to grinding and polishing to various grit levels. In addition we offer a number of surface coating options such as PTFE or our own Black-Maus-Coatings.

Typically a mounting frame is fitted to all mould halves. Fabricated from steel tube the frame is fixed directly to ‘mounting posts’ which are part of the casting, thus providing extra strength and protecting the mould shells. Clamps for keeping the mould closed are applied directly to the mounting frame providing an equal distribution of the clamping forces o the flanges.

For many moulds there will also be thread insert retainers or holding magnets applied.
