About PCS

PCS is a manufacturer of mold components and tooling accessories, with a product line that includes ejector pins, leader pins, bushings, and related hardware for injection molding and die-casting operations. The brand's catalog is built around standard and precision components that meet common dimensional and tolerance requirements in mold bases and tooling assemblies. PCS products are typically specified by nominal diameter, overall length, head dimensions, and material condition, allowing engineers to match components to existing mold designs without custom fabrication. The ejector pins in the PCS line are made from nitrided steel, which provides a wear-resistant surface for high-cycle production environments. These pins are available in both inch and metric sizes, with nominal diameters ranging from 1 mm to 9/32 in and overall lengths from 100 mm to 10 in. Head diameters and thicknesses are held to tolerances such as +0.062/-0.000 in for inch sizes and +2.0/-0.0 mm for metric sizes, ensuring proper seating in ejector plates. Surface finishes on some pins are specified between 4 uin and 10 uin, which supports smooth ejection and reduces friction against mold surfaces. The pins are intended for use in injection molds and die-cast tooling, where they push finished parts out of the cavity after solidification. PCS also supplies leader pins and bushings that guide mold halves during opening and closing, maintaining alignment and protecting cavity surfaces. These components are available in various diameters and lengths to fit standard mold bases. 3G Electric stocks over 180 PCS SKUs, covering ejector pins, leader pins, bushings, and other mold components. The product range includes both inch and metric options, with multiple head styles and tolerance classes. For plant engineers and maintenance managers, this means access to replacement components that match original specifications without waiting for custom orders. Procurement specialists can source PCS mold components through 3G Electric's global distribution network, with the ability to compare specifications across SKUs and request quotes for volume purchases. The catalog is structured to support MRO and production needs, with components that are commonly used in plastics processing, die casting, and other industrial molding applications. 3G Electric provides technical documentation and specification details for each PCS SKU, including nominal dimensions, tolerances, material condition, and surface finish where applicable. This allows buyers to verify compatibility with existing tooling before ordering. The PCS line is positioned as a source for standard mold components that meet common industry tolerances, reducing downtime when replacements are needed. For operations running multiple molding machines, maintaining an inventory of PCS ejector pins, leader pins, and bushings can help minimize production interruptions caused by worn or broken tooling components. 3G Electric supports this by offering the full range of PCS SKUs with global shipping and technical support for specification questions.

Common Applications

• Injection molding — PCS nitrided ejector pins (e.g., NP13-10 OS) for ejecting plastic parts from mold cavities in high-cycle production.
• Die casting — PCS straight ejector pins (e.g., JMP03-150) for pushing solidified metal parts out of die-cast tooling.
• Mold maintenance — PCS leader pins and bushings to restore alignment in worn mold bases and prevent flash or mismatch.
• Plastics processing — PCS oversized ejector pins (e.g., NP19-10) for molds requiring increased bearing surface or repair of worn ejector holes.
• Tooling assembly — PCS metric ejector pins (e.g., MP015-100) for use in molds built to metric standards.
• High-wear applications — PCS nitrided ejector pins with 4–10 uin surface finish for reduced friction and extended service life in abrasive molding compounds.
