Product Description
Introduction
Plastic Mold Bush is a precision guiding component used in injection mold systems to ensure accurate alignment between guide pillars and mold plates. It helps maintain stable movement during mold opening and closing cycles, reducing friction and preventing misalignment. By supporting smooth guiding performance, it improves molding accuracy and overall production consistency in high-volume plastic manufacturing.
The product is manufactured from high-quality materials such as bearing steel, alloy steel, or bronze, followed by heat treatment and precision grinding processes. These manufacturing steps ensure excellent hardness, dimensional stability, and wear resistance under continuous operation. The inner surface is finely finished to provide smooth sliding with the guide pillar, even in high-speed and high-load molding conditions.
Plastic Mold Bush is widely applied in plastic injection molds, automotive components, electronic product housings, household appliance molds, and precision industrial tooling systems. It is compatible with international standards such as MISUMI, HASCO, DME, DIN, and ISO, and can also be customized according to drawings or special requirements. With reliable performance and long service life, it is an essential part for improving mold accuracy and reducing maintenance costs.
