Gibraltar MEP1108-G Straight Ejector Pin 12.5mm Steel

Product Description

The GIBRALTAR MEP1108-G is a straight ejector pin used in plastic injection mold tooling to push finished parts out of the mold cavity at the end of each cycle. Machined from steel with a nitride finish for surface hardness and wear resistance, this pin measures 12.5 mm in diameter with a 623 mm pin length and a 630 mm overall length. The head measures 20 mm in diameter and 7 mm in height, providing positive retention in the ejector plate. Toolmakers, moldmakers, and mold maintenance technicians select this pin for high-cycle production mold applications where dimensional consistency and surface durability are required.

This ejector pin is suited for use in injection mold bases requiring a 12.5 mm diameter straight pin with a flanged head. It is a standard-profile pin appropriate for medium-to-large mold frames in both prototype and production tooling environments. The nitride surface treatment improves resistance to galling and extends service life in abrasive or high-frequency cycling conditions. Installation is performed during mold build or scheduled mold maintenance by qualified toolroom personnel.

Key Features

• 12.5 mm pin diameter for precise fit in standard ejector pin bores
• 630 mm overall length with 623 mm usable pin length for deep mold frames
• Steel construction with nitride finish for surface hardness and wear resistance
• 20 mm head diameter and 7 mm head height for positive ejector plate retention
• Straight ejector pin profile compatible with standard ejector plate systems

Compatibility

Designed as a standard straight ejector pin replacement for injection mold tooling requiring a 12.5 mm pin diameter and 630 mm overall length with a flanged head configuration.

Installation Notes

Installation and replacement of ejector pins is performed by toolmakers or mold maintenance technicians during mold disassembly. The mold must be fully de-energized and all hydraulic or mechanical clamp pressure released before ejector system work begins. Pins should be inspected for straightness and surface condition before installation. Follow the mold manufacturer's specifications for ejector plate assembly and pin retention.
