Polystyrene
Machining
Semi-finished Polystyrene parts can easily be machined by a variety of different methods including punching, sawing, drilling, milling, and turning by using the tools and machines customary for metalworking or woodworking. Owing to the low thermal conductivity and the low softening temperature, the cutting surfaces must be cooled by a current of air or with water. The high-impact Polystyrenes have a lower tendency to splinter and can be machined much more easily.
