Gibraltar MT7670-G Straight Ejector Pin 3.5mm Steel

Product Description

The GIBRALTAR MT7670-G is a straight ejector pin designed for use in injection mold tooling applications. This pin features a 3.5 mm pin diameter and a 160 mm overall length, making it a standard-dimension component for mold base assemblies. Constructed from steel with a nitride finish, the MT7670-G offers surface hardness and wear resistance suited to repetitive molding cycles. Mold makers, tool and die technicians, and plastic injection mold maintenance professionals install this type of pin as part of the ejector system that pushes finished parts from the mold cavity after each shot.

This ejector pin is used in plastic injection molds where a straight pin style is required. The 7 mm head diameter seats into the ejector plate retainer, while the 157 mm pin length extends through the mold to contact and eject the molded part. It is suited for residential tooling shops, production mold departments, and maintenance crews performing ejector system rebuilds or pin replacements. The nitride finish helps reduce galling and extends service life in high-cycle mold environments.

Key Features

• Straight ejector pin style for standard mold base compatibility
• 3.5 mm pin diameter with 157 mm pin length and 160 mm overall length
• 7 mm head diameter and 3 mm head height for positive retention in ejector plate
• Steel construction with nitride finish for surface hardness and wear resistance
• Single-piece quantity packaging suited for spot replacement or tooling repair

Compatibility

Designed as a standard straight ejector pin replacement for plastic injection mold tooling assemblies requiring a 3.5 mm diameter pin with a 160 mm overall length.

Installation Notes

Ejector pin replacement is performed by mold makers or tool and die technicians with the mold fully de-energized, cooled, and removed from the press. The ejector plate assembly must be disassembled to access and swap the pin. Inspect the ejector plate bore and retainer pocket for wear before installing a new pin. Follow applicable shop safety and tooling maintenance procedures when working with mold components under spring or hydraulic tension.
