Gibraltar MEP1103-G Straight Ejector Pin 12.5mm 160mm

Product Description

The GIBRALTAR MEP1103-G is a straight ejector pin used in injection mold tooling to push finished parts out of a mold cavity at the end of each cycle. This pin features a 12.5 mm diameter pin body, a 153 mm pin length, and a 160 mm overall length, with a 20 mm head diameter and 7 mm head height that seats securely in the ejector plate. Constructed from steel with a nitride finish, it offers surface hardness and wear resistance suited to repetitive cycling in production mold applications. Installation and replacement are performed by mold technicians and toolmakers during scheduled mold maintenance or part changeovers.

This ejector pin is designed for use in plastic injection molds across a range of production environments, including both high-volume and short-run tooling setups. It is a direct-fit replacement for worn or damaged straight ejector pins of matching dimensions. The nitride finish reduces galling and extends service life in demanding cycling conditions. Mold shops, toolrooms, and production facilities stocking standard ejector pin sizes will find this pin fits common mold base configurations requiring a 12.5 mm pin diameter.

Key Features

• 12.5 mm pin diameter for a precise fit in matching mold ejector bores
• 160 mm overall length with 153 mm usable pin length
• 20 mm head diameter and 7 mm head height for positive seating in ejector plates
• Steel construction with nitride finish for surface hardness and wear resistance
• Straight ejector pin geometry for standard mold ejection applications

Compatibility

Designed as a standard straight ejector pin replacement for injection mold tooling requiring a 12.5 mm pin diameter and 160 mm overall length.

Installation Notes

Ejector pin replacement is performed by qualified mold technicians or toolmakers. Always ensure the mold is fully cooled, depressurized, and the press is locked out and tagged out before accessing the ejector assembly. Pins should be inspected for proper fit and smooth travel in the ejector bore before returning the mold to production. Consult the mold design documentation to verify pin placement and ejector plate alignment prior to reassembly.
