Round Head Ejector Pins and Sleeves with Polished Surface Treatment
Round head ejector pins and sleeves with polished surface treatment are precision components designed for mold ejection systems. Sleeves, also known as top tubes or hollow sleeve pins, are available in straight and stepped configurations to accommodate various mold requirements.
Product Overview
These components are engineered for round through-holes or blind holes in products where ejection mechanisms require metal fittings. The system consists of a cylinder and sleeve pin assembly, with the sleeve mounted on the ejector plate and the sleeve pin secured to the bottom plate. During mold operation, the sleeve ejects the material from the sleeve pin after mold opening.
When wear or machining tolerance issues occur in sleeves, holes, or shafts, these components can be telescopically adjusted and restored to original specifications using cylinder sets, ensuring continued precision performance.
