Gibraltar HEP3563-G Straight Ejector Pin 1/8 in Steel

Product Description

The GIBRALTAR HEP3563-G is a straight ejector pin designed for use in injection mold tooling applications. Machined from steel with a nitride finish for improved surface hardness and wear resistance, this pin measures 1/8 inch in pin diameter and 14 inches in overall length, with a usable pin length of 13.875 inches. The head diameter is 1/4 inch and the head height is 1/8 inch. It is intended for installation by moldmakers, tool and die technicians, and maintenance machinists working on injection mold assemblies or progressive die sets that require reliable, consistent ejection performance.

This straight ejector pin is suited for use in standard ejector plate assemblies found in plastic injection molds and similar tooling. The 1/8 inch diameter makes it appropriate for small-feature ejection points where precision fitment is critical. Its steel construction and nitride surface treatment make it a practical choice for moderate- to high-cycle mold applications in production shop environments.

Key Features

• Straight ejector pin configuration for standard ejector plate mounting
• 1/8 inch pin diameter with a 1/4 inch head diameter for positive retention in the ejector plate
• 13.875 inch pin length with 14 inch overall length for deep-draw or extended ejection stroke applications
• Steel construction with nitride finish for surface hardness and corrosion resistance
• 1/8 inch head height provides low-profile seating in standard ejector plate counterbores

Compatibility

Designed as an OEM-style replacement or new-installation ejector pin for standard ejector plate assemblies requiring a 1/8 inch diameter straight ejector pin with a 1/4 inch head diameter.

Installation Notes

Installation is performed by moldmakers or tool and die technicians during mold build or maintenance. The mold should be fully de-energized, hydraulic pressure relieved, and the ejector system reset to the home position before removing or installing ejector pins. Pins should be inspected for straightness and surface condition before installation. Do not force pins into undersized bores; verify hole tolerances match pin diameter to avoid galling or binding during operation.
