Frequently Asked Questions
The primary function of a sprue bushing is to guide molten plastic into the mold cavity while ensuring a steady, controlled flow of material throughout the injection process.
They are typically manufactured from high-temperature and wear-resistant materials, such as premium-grade steel or aluminum alloys, to withstand harsh injection molding environments.
Sprue bushing design must take into critical account the flowability of the plastic material, precise temperature control, and the overall structural strength of the mold.
By optimizing material flow and temperature control, a well-designed sprue bushing effectively minimizes common molding defects such as air bubbles and cold material.
Sprue bushings operate under high-temperature and high-pressure conditions. High wear resistance ensures they maintain shape and performance over long production runs without degrading.
