Bearing Steel SUJ2 Materials type C Sprue Bushing Heat Resistant Wear Resistant for Injection Molding
Description
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.

Materials
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.
