Gibraltar MEP1081-G Straight Ejector Pin 10.2mm 500mm Steel

Product Description

The GIBRALTAR MEP1081-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. Machined from steel with a nitride finish for improved surface hardness and wear resistance, this pin measures 10.2 mm in pin diameter with a 495 mm pin length and a 500 mm overall length. The head diameter is 16 mm with a 5 mm head height, providing a positive seating surface against the ejector plate. Mold toolmakers, die makers, and tool and die technicians install this component during mold builds or maintenance cycles.

This ejector pin is suited for use in injection mold bases across a range of plastic molding applications. It is appropriate for both prototype tooling and production mold sets where a standard straight-body ejector pin with a flanged head is specified. The nitride surface treatment helps extend service life in high-cycle production environments by reducing galling and friction against the mold plate bore. Installations requiring a 10.2 mm diameter pin in a 500 mm overall length are the primary fit for this part.

Key Features

• Steel construction with nitride finish for improved hardness and wear resistance
• 10.2 mm pin diameter for consistent fitment in precision-bored ejector pin holes
• 500 mm overall length with 495 mm usable pin length
• 16 mm head diameter and 5 mm head height for positive retention in ejector plates
• Straight-body design compatible with standard ejector plate assemblies
• Single-piece quantity packaging suitable for individual replacement or toolroom stock

Compatibility

Designed as a standard straight ejector pin replacement for injection mold tooling requiring a 10.2 mm diameter pin at 500 mm overall length with a flanged head.

Installation Notes

Installation is performed by qualified mold technicians or tool and die makers. The mold should be fully de-energized, cooled, and removed from the press before ejector pin service begins. Verify bore diameter and ejector plate counterbore dimensions match the pin and head before pressing the pin into place. Do not force a pin into an undersized bore, as this can damage the mold plate and compromise pin alignment.
