After the powder has reached a specified thickness on the half, it’s cured into a polymeric film utilizing elevated temperatures (~200°C), in a convection oven. Thermosetting polymers will crosslink during the curing course of precision machining to improve performance, however thermoplastic varieties merely flow while heated to form the final coating. Media blasting makes use of a pressurized jet of abrasive media to apply a matte, uniform finish to parts. The most typical media used are various sizes of glass beads or sand, although for different levels of abrasion, plastic beads are also used.
