 Background

    The sprue bush is a part that allows plastic material to be injected from the nozzle into the interior of the mold. The tapy A sprue bushing is fixed to the mold with 2 bolts to prevent it from falling off due to the injection pressure. In order to prevent leakage of plastic material, the feed port is generally designed in an arc shape. 

    Regarding the material, SKD61 and S45C are commonly used. S45C is a medium carbon steel with excellent wear resistance, but the ductility is reduced, the quenching performance is not good, and the hardness after quenching is HRC42, so it is used to make the sprue bushing of the low-end mold, after the high temperature, its need to spray anti-rust oil or other anti-rust treatment to prevent rust.

    The relationship between the size of the sprue bushings and the tonnage of the injection molding machine is as follows. the types of plastics materials being injection molded have a littell impact on them.
