Gibraltar MT7661-G Straight Ejector Pin 3mm 125mm Steel

Product Description

The GIBRALTAR MT7661-G is a straight ejector pin used in injection mold tooling to push finished parts out of mold cavities at the end of each cycle. The pin measures 3 mm in diameter with a 122 mm pin length and a 125 mm overall length. The 6 mm head diameter and 3 mm head height seat securely in the ejector plate, maintaining positive retention during high-cycle operation. Constructed from steel with a nitride finish, this pin delivers surface hardness that resists wear and galling. Mold builders and toolroom technicians are the primary installers.

This ejector pin is suited for plastic injection molds used in production environments where tight dimensional tolerances and consistent part ejection are required. The straight pin configuration is one of the most common ejector types, fitting a wide range of standard mold base designs. The nitride surface treatment helps extend service life in abrasive or high-temperature molding conditions. Sold individually, it is a practical replacement or spare for worn or broken pins in existing tooling.

Key Features

• 3 mm pin diameter for use in standard ejector pin bores of the same size
• 125 mm overall length with 122 mm usable pin length
• 6 mm head diameter and 3 mm head height for positive ejector plate seating
• Steel construction with nitride finish for surface hardness and wear resistance
• Straight ejector pin configuration compatible with common mold base layouts
• Sold as a single unit with no minimum order beyond one piece

Compatibility

Designed as an OEM-style replacement or spare straight ejector pin for standard injection mold tooling that accepts a 3 mm diameter ejector pin with a 6 mm head.

Installation Notes

Ejector pin replacement is performed by mold builders or toolroom machinists with the mold fully de-energized, cooled, and removed from the press. Inspect the ejector plate bore and guide bushings for wear before installing a new pin. The pin should slide freely without binding throughout its full stroke. Follow your facility safety procedures and applicable toolroom practices when disassembling and reassembling ejector systems.
