Gibraltar MT7708-G Straight Ejector Pin 8mm 125mm Steel

Product Description

The GIBRALTAR MT7708-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. Machined from steel with a nitride finish for wear and corrosion resistance, this pin measures 8 mm in diameter with a 120 mm pin length and a 125 mm overall length. The head diameter is 14 mm with a 5 mm head height, providing a solid bearing surface against the ejector plate. It is installed and replaced by toolmakers, mold technicians, and precision machinists during mold maintenance or build operations.

This ejector pin is suited for use in plastic injection molds across a wide range of production environments, including both prototype tooling and high-volume production molds. Its straight profile and standard head geometry make it applicable wherever a consistent, reliable ejector pin is required in the 8 mm diameter class. The nitride surface treatment supports extended service life in demanding cycle environments.

Key Features

• Straight ejector pin profile for standard mold ejection applications
• 8 mm pin diameter with 120 mm pin length and 125 mm overall length
• 14 mm head diameter and 5 mm head height for positive ejector plate engagement
• Steel construction with nitride finish for wear and corrosion resistance
• Sold individually, no minimum quantity requirement beyond single-unit purchase

Compatibility

Designed as a standard-geometry straight ejector pin for use in plastic injection molds requiring an 8 mm diameter ejector pin with a 125 mm overall length.

Installation Notes

Ejector pin replacement and installation is performed by qualified toolmakers or mold technicians with the mold fully removed from the press and all hydraulic and mechanical energy locked out. Pins should be inspected for straightness and surface condition before installation, and the ejector pin bore in the mold should be verified for proper fit and clearance. Do not force pins into undersized bores, as this can cause galling or mold damage.
