Polymer Fabricated Masks

The manual fabrication of plastic masks is labour intensive and extremely skilful. A number of polymer pieces are cut and bent to shape. They are then put together by means of a plastic welding process.

This method is typically used to produce prototypes or when a very low number of masks are required. The production of manually fabricated polymer masks is of great assistance in the development of long-term injection moulding projects. Preliminary coating trials and pre-production sampling may be carried out with the use of these masks. These are particularly helpful to determine the orientation of masks in planets as well as number of masks to be fitted per planet (for aluminising) or frame (for spray painting).
