Product Description
Introduction
Ejector Plate Guide Bushing is a precision mold component designed to ensure accurate alignment and smooth movement of ejector plates in injection molds and die systems. It works together with guide pillars to maintain stable positioning of the ejection system during repeated opening and closing cycles. This helps improve molding accuracy, reduce mechanical deviation, and ensure consistent production quality in high-volume manufacturing environments.
Manufactured from high-quality bearing steel or hardened tool steel, Ejector Plate Guide Bushing provides excellent wear resistance, high strength, and long service life. Advanced CNC machining, precision internal grinding, and heat treatment processes ensure tight dimensional tolerances up to ±0.002 mm. The finely polished inner surface actively reduces friction between moving components, allowing smooth guiding performance even under continuous high-speed operation. This enhances system stability and reduces maintenance requirements over long-term use.
Ejector Plate Guide Bushing is widely applied in injection molding, plastic product manufacturing, automotive components, household appliance parts, and precision industrial tooling systems. It is suitable for both standard mold bases and customized mold structures, offering flexible design options such as inner diameter, outer diameter, length, and lubrication features. Its reliable performance makes it an essential component for maintaining stable ejector movement, improving mold efficiency, and ensuring long-term operational durability in demanding industrial environments.
