Gibraltar HEP3572-G Straight Ejector Pin 3/16 in Steel

Product Description

The GIBRALTAR HEP3572-G is a straight ejector pin used in injection mold tooling to push finished parts out of a mold cavity at the end of the molding cycle. Machined from steel with a nitride finish for surface hardness and wear resistance, this pin measures 3/16 inch in diameter with a 10-inch overall length and a 9.812-inch pin length. The 3/8-inch head diameter and 3/16-inch head height seat the pin securely in the ejector plate. Mold makers, toolroom machinists, and die maintenance technicians install these pins as standard components in ejector plate assemblies.

This ejector pin is suited for use in injection molds, die casting dies, and compression mold tooling across both production and prototype applications. The straight pin geometry fits standard through-bored ejector plate configurations. The nitride surface treatment helps resist galling and wear during high-cycle mold operation, making it appropriate for moderate- to high-volume production tooling environments where consistent ejection force and pin longevity are required.

Key Features

• Straight ejector pin geometry for standard ejector plate installations
• 3/16 inch pin diameter with 9.812 inch pin length and 10 inch overall length
• 3/8 inch head diameter and 3/16 inch head height for positive seating in ejector plates
• Steel construction with nitride finish for surface hardness and wear resistance
• Sold individually, compatible with single-pin replacement or full ejector plate builds

Compatibility

Designed as an OEM-style replacement or toolroom stock ejector pin for injection mold and die tooling assemblies requiring a straight pin with a 3/16 inch diameter and 10 inch overall length.

Installation Notes

Ejector pins are installed and serviced by mold makers and toolroom technicians. The mold should be fully cooled and all hydraulic or mechanical press pressure relieved before ejector plate access. Pins must be seated flush and square in the ejector plate to prevent binding or premature wear during mold cycling. Verify pin length and head dimensions against the mold blueprint before installation to confirm fit.
