Gibraltar HEP3591-G Straight Ejector Pin 17/64 in Steel

Product Description

The GIBRALTAR HEP3591-G is a straight ejector pin designed for use in injection mold tooling and die applications. It transfers ejection force from the mold's ejector plate to push molded parts cleanly out of the cavity. Machined from steel with a nitride finish for surface hardness and wear resistance, this pin measures 17/64 inches in diameter with a 10-inch overall length and a 7/16-inch head diameter. The head height is 1/4 inch and the usable pin length is 9-3/4 inches. Mold makers, toolmakers, and die maintenance technicians install this component during mold builds or routine pin replacement.

This ejector pin is suited for precision mold tooling environments including plastic injection molds and die casting applications. The nitride surface treatment reduces galling and extends service life in high-cycle molds. It is a standard straight-type pin, appropriate for conventional ejector plate systems where consistent pin diameter and accurate length are critical to part quality and mold function.

Key Features

• Straight ejector pin geometry for standard ejector plate systems
• 17/64 inch pin diameter with 9-3/4 inch pin length
• 7/16 inch head diameter and 1/4 inch head height for positive ejector plate seating
• Steel construction with nitride finish for surface hardness and galling resistance
• 10-inch overall length accommodates common mold base thicknesses
• Lightweight at 0.19 pounds for easy handling during pin layout and installation

Compatibility

Designed as a standard OEM-style straight ejector pin for use in injection mold tooling and die assemblies requiring a 17/64 inch diameter straight pin with a 10-inch overall length.

Installation Notes

Ejector pins are installed and serviced by toolmakers or mold maintenance technicians. Always ensure the mold is fully de-energized, de-pressurized, and cooled before disassembling the ejector system. Verify pin diameter and length against the mold drawing before installation to confirm proper fit and ejector plate alignment. Pins should move freely without binding in their bores; forced installation can cause pin breakage or mold damage.
