Gibraltar HEP3713 Straight Ejector Pin 13/32 in 18 in Steel

Product Description

The GIBRALTAR HEP3713 is a straight ejector pin used in injection mold tooling to push finished parts out of the mold cavity at the end of each cycle. Machined from steel with a nitride finish, this pin measures 13/32 inches in diameter and 18 inches in overall length. The nitride surface treatment improves hardness and wear resistance, extending service life under repeated ejection cycles. The head measures 11/16 inches in diameter with a 1/4 inch head height, providing positive retention in the ejector plate. Mold technicians and toolroom machinists select this pin as a direct replacement or for new mold builds requiring this diameter and length combination.

This ejector pin is suited for use in plastic injection molds, die cast tooling, and similar mold base applications where a standard straight pin configuration is required. It fits into ejector plate assemblies in both production and prototype tooling. The 18 inch length accommodates deep-draw molds or tooling with extended ejector travel requirements. This pin is sold individually, making it practical for single-pin replacement without requiring bulk purchase.

Key Features

• 13/32 inch pin diameter for standard mold base fitment
• 18 inch overall length suits deep-draw and extended-ejector mold designs
• Nitride finish provides increased surface hardness and wear resistance
• 11/16 inch head diameter with 1/4 inch head height for secure ejector plate seating
• Steel construction for durability under high-cycle ejection loads
• Single-unit packaging allows targeted replacement without surplus stock

Compatibility

Designed as a standard straight ejector pin for use in injection mold and die cast tooling assemblies requiring a 13/32 inch diameter pin at 18 inches overall length.

Installation Notes

Installation is performed by toolroom machinists or mold technicians during mold maintenance or new build assembly. Always de-energize and lock out the molding press before accessing the ejector system. Verify pin hole diameter and ejector plate pocket dimensions against the pin head specs before installation. Do not force pins into undersized bores, as this can damage the mold base or cause pin galling during operation.
