High Heat Resistance Sprue Bushing HASCO Standard Injection Mould Parts
Sprue bushings are essential flow path components that facilitate the injection of molten plastic material from the injection molding machine nozzle into the mold interior. The bolt-type nozzle design ensures secure fixation using two bolts, preventing displacement due to injection pressure.
Available in multiple models including A type, B type, C type, D type, and E type, with A, B, and C being the most commonly used. Manufactured from SKD61 hot work die steel, these components offer exceptional heat resistance and wear-resistant properties. The feed port features an R arc angle design to prevent plastic material leakage.
Our precision manufacturing capabilities ensure that domestically produced plastic mold parts meet international leading standards for accuracy and durability.
