Gibraltar MEP1129-G Straight Ejector Pin 20mm 500mm Steel

Product Description

The GIBRALTAR MEP1129-G is a straight ejector pin designed for use in injection molds, die casting tooling, and progressive die sets. It features a 20 mm pin diameter and a 500 mm overall length, with a 26 mm head diameter and 8 mm head height that seat securely in the ejector plate. The pin body measures 492 mm in length and is machined from steel with a nitride finish, providing surface hardness and wear resistance under the high-cycle conditions typical of production mold work. Toolmakers and mold technicians specify this pin as a standard replacement or new-build component.

This ejector pin is suited for medium-to-large injection molds requiring a 20 mm diameter pin in a 500 mm length configuration. It is appropriate for both prototype and production tooling environments. The nitride surface treatment makes it a practical choice for high-volume runs where pin wear and galling are common concerns. Toolrooms serving automotive, industrial, and consumer-products molding operations will find this size relevant to deep-draw cavity work and large-part ejection systems.

Key Features

• 20 mm pin diameter with 492 mm usable pin length for deep mold applications
• 500 mm overall length accommodates thick mold base configurations
• 26 mm head diameter and 8 mm head height for positive ejector plate retention
• Steel construction with nitride finish for enhanced surface hardness and wear resistance
• Straight ejector pin geometry for standard through-hole ejection
• Sold individually — minimum order quantity of 1

Compatibility

Designed as a standard straight ejector pin for injection molds and die tooling requiring a 20 mm pin diameter and 500 mm overall length. Confirm ejector plate bore diameter and pin pocket depth against mold drawings before ordering.

Installation Notes

Ejector pin installation and replacement should be performed by a qualified toolmaker or mold technician with the mold fully de-energized, de-pressurized, and safely supported in a press or on a work surface. Inspect the ejector plate bores and guide bushings for wear before installing a new pin. Do not force the pin through a misaligned bore, as this can cause premature galling or pin breakage. Follow the mold manufacturer's maintenance procedures and applicable shop safety standards when working inside a mold assembly.
