Gibraltar MT7663-G Straight Ejector Pin 3mm 200mm Steel

Product Description

The GIBRALTAR MT7663-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. It features a 3 mm pin diameter, a 6 mm head diameter, and a 200 mm overall length. Constructed from steel with a nitride finish, this pin is built for repeated cycling in production mold environments where dimensional consistency and surface hardness are critical. It is installed and replaced by moldmakers, toolroom machinists, and maintenance technicians servicing injection mold assemblies.

This ejector pin is suited for use in standard injection molds requiring a 3 mm diameter ejector pin with a 197 mm pin length and a 3 mm head height. It fits into ejector pin retainer plates using a standard head pocket. Common applications include plastic injection molds in both prototype and production tooling environments. The nitride surface treatment improves wear resistance and reduces galling during repeated ejection strokes.

Key Features

• 3 mm pin diameter for use in precision-bored ejector pin holes
• 197 mm pin length with 200 mm overall length including head
• 6 mm head diameter and 3 mm head height for standard retainer plate pockets
• Steel construction with nitride finish for improved surface hardness and wear resistance
• Straight ejector pin geometry for direct, vertical part ejection

Compatibility

Designed as a standard straight ejector pin replacement for injection mold assemblies requiring a 3 mm diameter pin with a 200 mm overall length and a nitrided steel finish.

Installation Notes

Installation is performed by moldmakers or toolroom technicians during mold maintenance or pin replacement. The mold must be fully de-energized, cooled, and removed from the press before ejector pin service begins. Pins should be inspected for straightness and proper seating in the retainer plate before reassembly. Do not force a bent or oversized pin into a bored hole, as this can damage the mold plate.
