Gibraltar HEP3561-G Straight Ejector Pin 1/8 in Steel

Product Description

The GIBRALTAR HEP3561-G is a straight ejector pin designed for use in injection molds and die casting tooling. It drives molded or cast parts out of the mold cavity at the end of each cycle. The pin features a 1/8 inch pin diameter and a 10 inch overall length, with a 9-7/8 inch usable pin length. A nitride finish hardens the surface for wear resistance and extends service life in high-cycle mold environments. This pin is manufactured from steel and is intended for installation by toolmakers, moldmakers, and maintenance personnel working on production tooling.

This ejector pin is suited for plastic injection molds and similar tooling applications where precise, consistent part ejection is required. The 1/4 inch head diameter and 1/8 inch head height allow it to seat properly in standard ejector plate configurations. It is typically used in both prototype and production mold sets where a 1/8 inch pin diameter is specified by the tool design. Sold individually, it is well suited for replacing worn or broken pins during mold maintenance without purchasing in bulk.

Key Features

• 1/8 inch pin diameter for precise fitment in standard mold ejector bores
• 10 inch overall length with 9-7/8 inch pin length for deep mold applications
• 1/4 inch head diameter and 1/8 inch head height for standard ejector plate seating
• Steel construction with nitride finish for surface hardness and wear resistance
• Sold as a single pin — suitable for targeted replacement during mold maintenance

Compatibility

Designed as an OEM-style replacement ejector pin for injection molds and die casting tooling requiring a straight ejector pin with a 1/8 inch pin diameter and 10 inch overall length.

Installation Notes

Installation is performed by qualified toolmakers or mold maintenance technicians. Before replacing ejector pins, the mold must be fully cooled, the press locked out, and hydraulic pressure relieved per applicable safety procedures. Pins should be checked for straightness before installation and seated fully in the ejector plate without forcing. Verify pin clearance in the mold bore to prevent binding or premature wear during operation.
