Gibraltar MEP1107-G Straight Ejector Pin Steel Nitride

Product Description

The GIBRALTAR MEP1107-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 12.5 mm in diameter with a 493 mm pin length and a 500 mm overall length. The head measures 20 mm in diameter and 7 mm in height, providing a positive shoulder for seating in ejector plates. Mold makers, toolmakers, and die maintenance technicians install and replace these pins during mold builds and preventive maintenance cycles.

Straight ejector pins are a standard component in injection mold bases across plastics manufacturing, die casting support tooling, and metal stamping operations. This pin is suited for applications requiring a longer pin length in a medium-diameter configuration. It fits standard ejector plate assemblies where the head seats flush and the pin body passes through the ejector retainer plate and into the mold core.

Key Features

• Nitride surface finish improves hardness and wear resistance for extended service life in high-cycle molds
• 12.5 mm pin diameter suits medium-bore ejector through-holes in standard mold bases
• 500 mm overall length accommodates deep mold cores and long-stroke ejector travel
• 20 mm head diameter with 7 mm head height provides solid seating in ejector retainer plates
• Steel construction handles the compressive and bending loads typical of ejector pin service
• Single-piece quantity available for replacement of individual pins without purchasing full sets

Compatibility

Designed as an OEM-style replacement or new-build component for standard injection mold ejector plate assemblies requiring a straight ejector pin with a 12.5 mm pin diameter and 500 mm overall length.

Installation Notes

Ejector pin installation and replacement should be performed by qualified toolmakers or mold maintenance technicians with the mold fully de-energized, press locked out, and hydraulic pressure relieved before disassembly. The ejector plate assembly must be removed to access and seat the pin head properly in the retainer plate. Inspect the ejector through-hole in the mold core for wear or damage before installing a replacement pin. Follow the mold builder specifications for ejector plate clearance and pin fit to prevent galling or premature failure.
