Gibraltar MT7742-G Straight Ejector Pin 16mm 315mm Steel

Product Description

The GIBRALTAR MT7742-G is a straight ejector pin designed for use in injection molds and die casting tooling. It drives molded parts out of the cavity at the end of each cycle, allowing clean, repeatable part ejection. This pin measures 0.63 inches in pin diameter and 12.4 inches in overall length, with a pin length of 12.13 inches. The head diameter is 0.87 inches and the head height is 0.28 inches. Manufactured from steel with a nitride finish, it delivers surface hardness and wear resistance suited for high-cycle mold environments. Mold makers, toolroom machinists, and die maintenance technicians are the primary installers.

This ejector pin fits applications in plastic injection molds and progressive die tooling where a straight pin profile is required. It is suited for both prototype and production mold builds across a range of part geometries. The nitride finish reduces friction and galling during repeated ejection strokes, making it a practical choice for medium to high production runs where pin wear and surface degradation are common concerns.

Key Features

• Straight ejector pin profile for direct part ejection in injection molds and die tooling
• Steel construction with nitride finish for improved surface hardness and wear resistance
• 16 mm pin diameter with 308 mm pin length for deep cavity or long-stroke applications
• 22 mm head diameter and 7 mm head height for positive retention in ejector plates
• Sold individually, allowing single-pin replacement without purchasing a full set

Compatibility

Designed as a standard straight ejector pin for use in injection molds and die casting tooling requiring a 16 mm pin diameter. Confirm ejector plate bore diameter, pin length, and head pocket dimensions against your specific mold design before installation.

Installation Notes

Ejector pin installation and replacement is performed by mold makers or toolroom machinists working on press tooling. Always de-energize and lock out the press before accessing the mold. Pins should be checked for proper fit in the ejector plate bores and guided bushings before reassembling the mold stack. Do not force pins into undersized bores, as this can cause galling, pin damage, or mold damage.
