Gibraltar MT7721-G Straight Ejector Pin 10mm 500mm Steel

Product Description

The GIBRALTAR MT7721-G is a straight ejector pin used in injection mold tooling to push finished parts out of the mold cavity at the end of each cycle. This pin features a 10 mm diameter shaft, a 495 mm pin length, and a 500 mm overall length. The steel construction with a nitride finish provides wear resistance and surface hardness suited for high-cycle mold applications. Mold makers, tool and die technicians, and moldbuilders install these pins during mold build and maintenance operations.

This ejector pin is applicable to injection mold bases and die sets requiring a straight pin configuration. It fits ejector retainer plates with a standard head pocket accepting a 16 mm head diameter and 5 mm head height. The 495 mm pin length allows use in deep mold frames or extended ejector stroke assemblies common in both prototype and production tooling environments.

Key Features

• Straight ejector pin configuration for standard mold ejection systems
• 10 mm shaft diameter for use in matched ejector plate bore sizes
• 495 mm pin length accommodates deep mold frames and long ejector travel
• Steel construction with nitride finish for surface hardness and wear resistance
• 16 mm head diameter and 5 mm head height for secure retention in ejector plates

Compatibility

Designed as a direct-fit replacement or new-build component for injection mold assemblies requiring a straight ejector pin with a 10 mm shaft diameter and 500 mm overall length in a standard headed configuration.

Installation Notes

Installation is performed by qualified mold makers or tool and die technicians during mold build or scheduled maintenance. The mold should be fully de-energized, cooled, and separated before ejector plate disassembly. Pins should be checked for proper fit and free movement in the ejector plate bore before closing the mold. Do not force or modify the pin geometry to fit non-matching plate configurations.
