Gibraltar HEP3616-G Straight Ejector Pin 7/16 in Steel

Product Description

The GIBRALTAR HEP3616-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, it measures 7/16 inches in pin diameter and 10 inches in overall length, with a pin length of 9-3/4 inches. The head measures 11/16 inches in diameter and 1/4 inch in height. The nitride finish improves surface hardness and wear resistance, extending service life in high-cycle mold applications. This pin is installed and serviced by toolmakers, mold technicians, and die maintenance personnel.

Straight ejector pins are a standard component in plastic injection molds, die casting dies, and compression molds. This pin is suited for use in mold bases that accept standard ejector pin configurations. It is typically installed in the ejector plate assembly and aligned with the ejector retainer plate. Applications span both prototype and production tooling in industrial and manufacturing environments.

Key Features

• 7/16 inch pin diameter for compatibility with standard ejector pin bores
• 10 inch overall length with 9-3/4 inch usable pin length
• 11/16 inch head diameter and 1/4 inch head height for secure retention in ejector plates
• Steel construction with nitride finish for improved hardness and wear resistance
• Straight pin geometry for straightforward installation and replacement

Compatibility

Designed as an OEM-style replacement straight ejector pin for use in standard injection mold and die tooling applications that accept a 7/16 inch pin diameter.

Installation Notes

Installation is performed by qualified toolmakers or mold maintenance technicians. Before servicing the ejector assembly, ensure the molding machine is fully powered down, de-energized, and any hydraulic or pneumatic pressure is relieved. Pins should be measured and verified for length and diameter against the mold specification before installation. Do not force pins into undersized bores, as this can damage the pin, the mold plate, or both.
