Gibraltar MT7704-G Straight Ejector Pin 6mm 400mm Steel

Product Description

The GIBRALTAR MT7704-G is a straight ejector pin used in injection mold tooling and die work. It drives molded parts out of the cavity at the end of each cycle. The pin measures 6 mm in diameter and 400 mm in overall length, with a 395 mm pin length and a 12 mm head diameter. The head stands 5 mm tall, providing a positive shoulder seating against the ejector plate. Constructed from steel with a nitride finish, the MT7704-G offers surface hardness and wear resistance suited to high-cycle mold environments. Mold makers, tool-and-die technicians, and injection molding maintenance personnel are the primary installers.

This ejector pin is suited for use in plastic injection molds, die casting dies, and similar tooling where a straight-through ejection path is required. The 6 mm diameter fits standard ejector pin bushings and guide bores machined to that nominal size. The nitride finish reduces galling and extends service life in abrasive or high-temperature mold conditions. Sold individually, the MT7704-G is a direct stock replacement or new-build component for molds requiring pins of this diameter and length specification.

Key Features

• 6 mm pin diameter fits standard 6 mm ejector pin bores
• 400 mm overall length with a 395 mm active pin length
• 12 mm head diameter with a 5 mm head height for positive plate seating
• Steel construction with nitride finish for surface hardness and wear resistance
• Straight ejector pin geometry for direct, unobstructed part ejection

Compatibility

Designed as a standard straight ejector pin replacement or new-build component for injection molds and die tooling machined to accept a 6 mm diameter ejector pin with a 12 mm head diameter.

Installation Notes

Installation is performed by mold makers or tool-and-die technicians during mold maintenance or new tooling builds. The mold must be removed from the press and fully de-energized before ejector pin service begins. Pins should be inspected for straightness before installation, and the ejector pin bore should be checked for wear or damage. Follow shop-standard procedures for ejector plate assembly and pin retention.
