Gibraltar MT7730-G Straight Ejector Pin 12mm 500mm Steel

Product Description

The GIBRALTAR MT7730-G is a straight ejector pin designed for use in injection mold tooling and die casting applications. It features a 12 mm pin diameter and a 500 mm overall length, making it suited for deeper mold cavities that require extended reach. The pin is machined from steel and finished with a nitride treatment to improve surface hardness and wear resistance. A 20 mm head diameter and 7 mm head height provide a positive seating surface against the ejector plate. This component is installed and maintained by toolmakers, moldmakers, and mold maintenance technicians.

Straight ejector pins of this type are a standard component in plastic injection molds and die casting dies. They are used to push finished parts clear of the mold cavity after each cycle. With a 493 mm pin length and a robust steel construction, the MT7730-G is appropriate for use in larger production molds where consistent ejection performance across high cycle counts is required. It suits both OEM mold builds and replacement applications in existing tooling.

Key Features

• 12 mm pin diameter for high-load ejection duty in larger mold cavities
• 493 mm pin length with 500 mm overall length including the head
• 20 mm head diameter and 7 mm head height for secure ejector plate engagement
• Nitride finish improves surface hardness and extends service life in repetitive cycling
• Steel construction provides the strength and machinability standard in toolroom applications

Compatibility

Designed as a standard straight ejector pin replacement for injection mold and die casting tooling that specifies a 12 mm pin diameter and 500 mm overall length with a 20 mm head diameter.

Installation Notes

Installation is performed by qualified toolmakers or mold maintenance personnel. The mold must be fully depressurized, cooled, and de-energized before any ejector system service. Pins should be checked for proper fit and free movement within the ejector plate bore before the mold is returned to production. Consult the mold design drawings for correct pin placement and ejector plate clearance tolerances.
