Gibraltar HEP3581-G Straight Ejector Pin 7/32 in Steel

Product Description

The GIBRALTAR HEP3581-G is a straight ejector pin used in injection mold tooling to push finished parts out of a mold cavity at the end of each cycle. Machined from steel with a nitride finish for surface hardness and wear resistance, this pin measures 7/32 inches in pin diameter, 13.812 inches in pin length, and 14 inches in overall length. The head measures 13/32 inches in diameter and 3/16 inches in height. It is installed and maintained by toolmakers, mold technicians, and tool-and-die professionals working on injection mold assemblies in manufacturing environments.

This ejector pin is suited for use in plastic injection molds, die casting tooling, and similar mold base assemblies where a standard straight ejector pin configuration is required. The nitride surface finish improves cycle life by reducing friction and resisting galling against the mold plate bore. It is appropriate for both new mold builds and replacement applications where an existing straight ejector pin of matching geometry has worn or failed.

Key Features

• Straight ejector pin design for standard mold base installations
• Steel construction with nitride finish for improved surface hardness and wear resistance
• Pin diameter of 7/32 inches with overall length of 14 inches
• Head diameter of 13/32 inches and head height of 3/16 inches for positive seating against ejector plates
• Pin length of 13.812 inches provides precise dimensional control in ejector plate assemblies

Compatibility

Designed as an OEM-style replacement or new-build component for standard straight ejector pin applications in injection mold and die tooling assemblies requiring a 7/32 inch pin diameter and 14 inch overall length.

Installation Notes

Ejector pins are installed and serviced by qualified toolmakers or mold technicians. Before servicing an ejector assembly, the mold must be fully de-energized, cooled, and safely secured in a press or on a work surface. Pins should be inspected for straightness and finish condition before installation, and bores should be checked for proper clearance to prevent binding or galling during operation.
