Gibraltar MEP1055-G Straight Ejector Pin 6.5mm 500mm Steel

Product Description

The GIBRALTAR MEP1055-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. Machined from steel with a nitride finish for surface hardness and wear resistance, this pin measures 6.5 mm in diameter and 500 mm in overall length, with a 495 mm pin length. The 12 mm head diameter and 5 mm head height seat securely in the ejector plate, keeping the pin indexed during operation. Mold builders, toolmakers, and die maintenance technicians use ejector pins like this one as precision consumable components in production tooling.

This ejector pin is suited for plastic injection molds requiring a 6.5 mm pin diameter and a 500 mm overall length. It is a direct drop-in style replacement for straight ejector pin positions in two-plate and three-plate mold bases. The nitride surface treatment improves galling resistance at the pin-bushing interface, making it appropriate for higher-cycle molds where pin wear is a concern. Sold individually, this pin is typically ordered as a replacement during scheduled mold maintenance or unplanned downtime repair.

Key Features

• 6.5 mm pin diameter with 495 mm usable pin length for deep-draw cavity applications
• Nitride finish increases surface hardness and reduces wear at the pin-guide interface
• 12 mm head diameter and 5 mm head height for positive retention in ejector plates
• Steel construction provides the strength and machinability expected in production tooling
• 500 mm overall length covers long-draw mold configurations
• Sold as a single pin, allowing targeted replacement without buying a full set

Compatibility

Designed as a straight ejector pin replacement for injection mold tooling requiring a 6.5 mm pin diameter and 500 mm overall length. Verify ejector plate bore diameter, head pocket dimensions, and pin length against existing tooling drawings before installation.

Installation Notes

Ejector pin replacement is performed by toolmakers or mold maintenance technicians with the mold fully de-energized, cooled, and removed from the press. The ejector plate must be disassembled to access pin head pockets; inspect guide bushings for wear before installing new pins. Do not force a pin into an undersized or damaged bushing, as this can cause galling or pin breakage during the next production run. Follow applicable shop safety procedures for handling tooling steel components and mold assemblies.
