The GIBRALTAR HEP3578-G is a straight ejector pin used in plastic injection molds and die casting tooling to push finished parts out of the mold cavity at the end of each cycle. This pin features a 7/32 inch pin diameter, an overall length of 6 inches, and a pin length of 5.812 inches. Constructed from steel with a nitride finish, it is designed to resist wear and galling under the high-cycle, high-contact conditions typical of production mold tooling. Installation and replacement are performed by toolmakers and mold maintenance technicians.
This ejector pin is suited for use in injection mold bases where a standard straight ejector pin configuration is required. The 13/32 inch head diameter and 3/16 inch head height fit standard ejector retainer plates used in common mold base systems. It is applicable in both prototype and production tooling across a range of part sizes and materials. The nitride surface treatment improves case hardness and extends service life in repetitive ejection applications.
Designed as an OEM-style replacement or maintenance stock ejector pin for standard injection mold and die casting tooling that requires a straight ejector pin with a 7/32 inch diameter and 6 inch overall length.
Ejector pin replacement is performed by qualified toolmakers or mold maintenance technicians with the mold fully de-energized, depressurized, and cooled before service. Pins should be checked for proper fit within the ejector retainer plate and guided bushing before the mold is returned to production. Verify pin length and head dimensions against the mold design drawings to confirm proper fit before installation. Do not modify pin length by cutting unless the cut end is properly finished and deburred.
