Hot Runner Manual for Robust Molding of Semi-crystalline Resins
Maximizing productivity is an important factor in determining part cost. One way to improve productivity is using a hot runner system. The decision when to use a hot runner system is mainly influenced by “yield” as hot runners can add complexity and cost to molds and require additional maintenance. Due to continuous improvement in the hot runner design a robust molding process is possible even with traditionally more thermally sensitive thermoplastic resins.

Safety Restraint Systems
Dupont's Delrin® grades with highest mechanical performance allow reduction in part size while increasing safety with high-impact parts in the seat belt. Delrin® E-grades used for low emissions are available in three basic melt flow series that vary in their melt viscosity helps to reduced noise from seatbelt retractor parts to enhance driver experience and can withstand temperatures of -40°C to +95°C and are used in Pillar Loop, Retractors, Push Buttons and Seat Belts.
