What is Sprue Bushing Type A?
Sprue bushings are also called sprue bushes, spouts, and sprinklers.
Sprue bushings are hardened-steel mold components that accept an extrusion nozzle and provide the opening used to transfer molten plastic to the mold cavity. They help reduce cooling times and produce more rigid sprues.
The sprue bushing is a metal fitting used by a plastic mold to connect the injection molding mold and the injection molding machine.
Models of the sprue bushings: A type, B type, C type, D type, E type, etc., commonly used are A, B, and C types of sprue bushings.

Sprue bushing type A manufacturing material
- SKD61 hot work dies steel can produce high-end and very durable sprue bushing, and the hardness can reach 48~52HRC. The sprue bushing made with SKD61 has the characteristics of high-temperature resistance and durability, and the quality of the molded product is excellent.
- SUJ2-bearing steel is a commonly used manufacturing material for middle-end sprue bushing. The heat treatment hardness is about HRC52.
- S45C, the material used in the low-end mold, after the high temperature, spray anti-rust oil, and other anti-rust treatments to prevent rust.
