The innovation for polymerisation The PolyMaster is a polymerisation device for the casting/pressing technique using cold curing polymer. No acrylic flash is produced, which means no more raised bites. The retention system incorporates a magnet to ensure reliable repositioning of the model. The simple handling permits a time saving of 25 minutes over other techniques available on the market. The ease of investing the models makes for gentler handling and prevents incorrect pressing.
