Description du produit
Introduction
Ejector Pins are essential precision components used in plastic injection molds to release molded parts safely and consistently from the mold cavity after cooling. They are designed to provide smooth and reliable ejection while minimizing the risk of part deformation, ejector marks, Stuck, or damage during repeated production cycles. High dimensional accuracy, Droiture, and surface finish are especially important for stable mold operation and long service life.
Our ejector pins can be manufactured in a wide range of diameters, Durées, head dimensions, Tolérances, and material specifications to suit different mold designs and application requirements. Common material options include SKD61, H13, SKH51 and other tool steels, with heat treatment, Nitrage, Rectification de précision, and polishing available depending on the required hardness, Résistance à l’usure, and working conditions.
Ejector Pins are widely used in automotive, Électronique, Appareils électroménagers, Dispositifs médicaux, consumer products, and other injection molding applications. In addition to standard sizes, custom ejector pins can be produced according to customer drawings or samples, including special dimensions, stepped structures, Traitements de surface, and tight-tolerance requirements for demanding mold applications.
