Gibraltar HEP3750 Straight Ejector Pin 18 Inch Steel

Product Description

The GIBRALTAR HEP3750 is a straight ejector pin used in injection mold tooling and die assemblies. It features an 11/64 inch (0.1719 inch decimal) pin diameter and an 18 inch overall length, making it suited for deep mold cavities that require extended reach. The head measures 11/32 inch in diameter and 3/16 inch in height, providing a solid seating surface against the ejector plate. Constructed from steel, this pin delivers the hardness and wear resistance required for repeated ejection cycles in production tooling environments. Installation and replacement are handled by toolmakers and mold technicians as part of scheduled mold maintenance or emergency repair.

This ejector pin is used in plastic injection molds, die casting tooling, and similar metal forming or molding equipment. Its straight profile and standard head geometry make it a general-purpose replacement component for ejector systems where an 11/64 inch diameter pin and 18 inch length are specified. It is applicable in both production shop and tool room environments where mold components are regularly serviced or rebuilt.

Key Features

• 11/64 inch (0.1719 inch) pin diameter for precise fit in standard ejector pin bores
• 18 inch overall length suits deep mold cavities and extended ejector systems
• 11/32 inch head diameter and 3/16 inch head height provide positive retention against ejector plates
• Steel construction delivers hardness and durability through high-cycle production use
• Sold individually, compatible with standard ejector pin replacement workflows

Compatibility

Designed as a standard straight ejector pin replacement for injection mold and die tooling that specifies an 11/64 inch pin diameter and 18 inch overall length. Verify head diameter and head height against existing tooling drawings before installation.

Installation Notes

Ejector pin replacement is performed by qualified toolmakers with the mold removed from the press and all energy sources locked out and tagged out per OSHA lockout/tagout procedures. Inspect the ejector pin bore and ejector plate pocket for wear or damage before installing the new pin. Do not force the pin into an undersized or damaged bore. Confirm pin length and head dimensions match the original mold specification before closing the mold and returning it to service.
