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

To achieve precise parting lines we stress relieve the aluminium shells before matching together.

The moulding surfaces will be prepared according to customers' specifications. Common surface treatments ranging from sandblasting and/or shotpeening 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 to the flanges.

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