Hot Runner 1.2343 Precision Sprue Bush
The sprue bushing is the part that allows the plastic material to be injected into the mold from the nozzle.
Regarding materials, SKD61 and S45C are commonly used. S45C is a medium carbon steel with excellent wear resistance, but its ductility is reduced, and the quenching performance is not good. The hardness after quenching is HRC42. Therefore, it is used to make runner bushings for low-end molds. It needs to be sprayed to prevent rust at high temperatures. Oil or other anti-rust treatment to prevent rust.
The relationship between the runner bushing size and the tonnage of the injection molding machine is as follows. The type of plastic material used for injection molding has little effect on them.
