injection pressure minimizes the possibility of producing highly stressed parts. This is significant because many new thermoplastic polyurethane molded parts are painted, and paint systems require baking for 30 minutes at 122°C (250°F). Under these conditions, any molded-in stresses would relieve and the result would be a distorted part.

metal, undispersed fillers, etc.). Screens should be constructed from stainless steel wire for strength and corrosion resistance. Normally a screen pack makeup of 20-40-80-20 mesh screens is optimal. However, some processes have used up to 200 mesh with screen pack, but also serves as a mechanical seal between the barrel and the adapter to the die.
