Leading companies across the globe specify Delrin® acetal resin from Dupont for high-load mechanical applications, including gears, safety restraints, door systems, conveyor belts, healthcare delivery devices, and other demanding products and parts. Delrin® acetal (Polyoxymethylene POM) is an ideal ingredient in parts designed to replace metal. It combines low-friction and high-wear resistance with the stiffness and strength such applications require. It provides a wide operating temperature range (-40° C to 120° C) and exceptional colorability. It also mates well with metal and other polymers, and it offers dimensional stability in precision molding. Compared to acetal copolymer, Delrin® acetal homopolymer offers higher tensile strength, stiffness, creep and fatigue resistance, and significantly higher impact resistance. The combination of these excellent mechanical properties in a single material allows for thinner, lighter-weight parts, shorter molding cycles, and potential cost savings thanks to its higher impact resistance. Authentic Delrin® acetal resin is available exclusively from DuPont distributors, in stock shapes (sheets, rods, tubes).

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.
