Gibraltar HEP3634-G Straight Ejector Pin 0.625in Steel

Product Description

The GIBRALTAR HEP3634-G is a straight ejector pin designed for use in injection mold tooling and die applications. Machined from steel with a nitride finish for surface hardness and wear resistance, this pin measures 0.625 inches in pin diameter and 18 inches in overall length, with a usable pin length of 17.75 inches. The 0.875-inch head diameter and 0.25-inch head height provide secure seating in standard ejector plate assemblies. Tool and die makers, mold technicians, and machinist shops rely on components like this for reliable part ejection cycles in production tooling.

This ejector pin is suited for plastic injection molds, die casting tooling, and stamping die assemblies where a straight-profile pin is required. The nitride surface treatment improves resistance to galling and extends service life under repeated cycling conditions. Installations are common in both prototype and production mold bases where standard ejector pin configurations are specified.

Key Features

• Steel construction with nitride finish for improved surface hardness and wear resistance
• 0.625-inch pin diameter for compatibility with standard ejector plate bores
• 18-inch overall length with 17.75-inch active pin length
• 0.875-inch head diameter and 0.25-inch head height for positive ejector plate retention
• Straight ejector pin profile for direct, uniform ejection force application

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard straight ejector pin applications in injection mold and die tooling assemblies requiring a 0.625-inch pin diameter.

Installation Notes

Installation is performed by qualified tool and die makers or mold technicians. Always ensure the mold or die assembly is fully de-energized, de-pressurized, and secured before removing or replacing ejector pins. Verify pin diameter, head dimensions, and overall length against the existing tooling drawing before installation. Do not force pins into undersized bores; consult the mold base specification sheet for proper fit and clearance tolerances.
