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.
