Gibraltar HEP3502-G Shoulder Ejector Pin Steel Nitride

Product Description

The GIBRALTAR HEP3502-G is a shoulder ejector pin designed for use in injection mold tooling and die applications. This pin features a 1/32 inch pin diameter with a 3 inch pin length and a 6 inch overall length, making it suitable for molds requiring precise, controlled ejection stroke depth. The shoulder design provides positive seating and consistent alignment within the mold base. Constructed from steel with a nitride finish, the HEP3502-G offers surface hardness and wear resistance suited to repetitive cycling in production tooling. Installation and replacement are typically performed by toolmakers and mold maintenance technicians.

This shoulder ejector pin is used in plastic injection molds and progressive die tooling where accurate part ejection is required. The 1/4 inch head diameter and 1/8 inch head height allow the pin to seat flush within standard ejector retainer plates. The 1/8 inch shoulder diameter and 3 inch shoulder length provide the guided, supported fit needed to prevent lateral deflection under ejection force. This pin is sold individually and is appropriate for both new mold builds and replacement of worn or damaged ejector pins during mold maintenance.

Key Features

• Shoulder ejector pin design provides positive alignment and controlled seating in ejector retainer plates
• 1/32 inch pin diameter with 3 inch pin length for precise ejection depth
• 1/8 inch shoulder diameter and 3 inch shoulder length reduce lateral deflection during cycling
• Steel construction with nitride finish for surface hardness and extended wear life
• 1/4 inch head diameter and 1/8 inch head height for standard retainer plate compatibility
• 6 inch overall length accommodates standard mold base configurations

Compatibility

Designed as an OEM-style replacement or new-build component for injection mold and die tooling applications requiring a shoulder ejector pin with a 1/32 inch pin diameter and 6 inch overall length.

Installation Notes

Installation should be performed by a qualified toolmaker or mold maintenance technician with the mold fully depressurized and removed from the press before servicing ejector components. Verify that the ejector retainer plate bore and ejector plate clearance are dimensionally compatible with the head and shoulder of this pin before pressing into place. Inspect the pin for straightness and the mating bore for wear or damage prior to installation. Follow the mold manufacturer's documented ejector system service procedures.
