Gibraltar HEP3641-G Straight Ejector Pin 0.75 in Steel

Product Description

The GIBRALTAR HEP3641-G is a straight ejector pin designed for use in injection mold tooling applications. It features a 0.75-inch pin diameter, an overall length of 18 inches, and a pin length of 17.75 inches. Constructed from steel with a nitride finish, this pin is built to withstand the repeated mechanical stress and heat cycles common in production mold environments. The nitride surface treatment improves hardness and wear resistance, extending service life in high-cycle tooling. Toolmakers, mold technicians, and die shop professionals will recognize this as a standard straight-type ejector pin suited for precision mold base assemblies.

This ejector pin is used in plastic injection mold tooling where controlled, repeatable part ejection is required. The 1-inch head diameter and 0.25-inch head height allow it to seat properly in standard ejector plates and retainer plates. Its 18-inch overall length makes it suited for deeper mold cavities or tooling requiring extended ejector travel. It is appropriate for both prototype tooling and production mold applications across a range of industries where steel mold components are specified.

Key Features

• Straight ejector pin type for straightforward installation in standard ejector plate assemblies
• 0.75-inch pin diameter provides substantial cross-section for higher ejection loads
• Steel construction with nitride finish for improved surface hardness and wear resistance
• 1-inch head diameter and 0.25-inch head height for proper seating in ejector retainer plates
• 17.75-inch pin length with 18-inch overall length accommodates deep mold cavities

Compatibility

Designed as a standard straight ejector pin replacement for injection mold tooling that accepts a 0.75-inch diameter straight ejector pin with a 1-inch head diameter and 18-inch overall length.

Installation Notes

Installation is performed by qualified toolmakers or mold technicians during mold build or maintenance. The mold must be fully de-energized, cooled, and safely staged before ejector system disassembly. Confirm pin fit and travel clearance within the ejector plate before closing the mold. Do not force or modify the pin geometry during installation, as dimensional integrity is critical to proper ejection function and mold surface protection.
