Gibraltar MEP1101-G Straight Ejector Pin 12.2mm 400mm Steel

Product Description

The GIBRALTAR MEP1101-G is a straight ejector pin designed for use in injection mold tooling applications. Machined from steel with a nitride finish, this pin provides the hardness and wear resistance required for high-cycle mold ejection. It features a 12.2 mm (0.480 inch) pin diameter, a 20 mm head diameter, and a 400 mm overall length with a usable pin length of 393 mm. The nitride surface treatment reduces friction and extends service life in demanding production environments. This component is installed by toolmakers, mold builders, and precision machining professionals who require consistent, reliable ejector pin performance.

Straight ejector pins are a standard component in injection molding, die casting, and stamping tooling. This pin is suited for use in mold bases where a 12.2 mm bore is specified and a 400 mm overall length is required. It is appropriate for both new mold builds and replacement of worn or damaged ejector pins in existing tooling. Industrial toolmakers and mold maintenance technicians working in plastics processing, rubber molding, and similar manufacturing environments are the primary installers of this type of component.

Key Features

• 12.2 mm pin diameter for precise fit in standard ejector pin bores
• 393 mm pin length with 400 mm overall length including 7 mm head height
• 20 mm head diameter provides positive seating against ejector plate
• Steel construction with nitride finish for enhanced surface hardness and wear resistance
• Straight pin type for straightforward drop-in installation in compatible mold bases

Compatibility

Designed as a standard straight ejector pin replacement or new-build component for injection mold tooling requiring a 12.2 mm pin diameter and 400 mm overall length.

Installation Notes

Installation is performed by qualified toolmakers or mold maintenance technicians. Before servicing any mold, ensure the press is locked out and all hydraulic and pneumatic circuits are fully depressurized. Ejector pins should be inspected for bore fit and plate seating before the mold is returned to service. Do not modify pin length by cutting unless the cut end is properly deburred and finished to maintain fit tolerances.
