Gibraltar MEP1137-G Straight Ejector Pin 9mm 500mm Steel

Product Description

The GIBRALTAR MEP1137-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. Machined from steel with a nitride finish, this pin measures 9 mm in diameter with a 495 mm pin length and a 500 mm overall length. The 14 mm head diameter and 5 mm head height seat the pin securely in the ejector plate. The nitride surface treatment improves hardness and wear resistance, extending service life under repeated cycling in production tooling environments. Mold makers and toolroom machinists are the primary installers and users of this component.

This ejector pin is suited for use in injection molds, die cast tooling, and similar mold base assemblies where a straight ejector profile is required. It is appropriate for both new mold builds and replacement applications in existing tooling. The 9 mm diameter and 500 mm overall length make it a fit for deeper mold cavities common in medium to large part production. Toolroom and mold maintenance technicians select this pin when matching existing ejector layouts or designing new ejection systems.

Key Features

• 9 mm pin diameter for precise fit in standard ejector pin bushings
• 500 mm overall length accommodates deep mold cavities
• Nitride finish increases surface hardness and reduces wear over extended cycling
• 14 mm head diameter and 5 mm head height for positive seating in ejector plates
• Steel construction provides the strength and machinability expected in production tooling

Compatibility

Designed as an OEM-style replacement or new-build component for injection mold and die cast tooling assemblies requiring a straight ejector pin with a 9 mm diameter and 500 mm overall length.

Installation Notes

Installation is performed by qualified mold makers or toolroom machinists. Ensure the mold is fully de-energized, cooled, and clamping pressure is fully relieved before accessing the ejector assembly. Verify the ejector pin bore diameter and ejector plate counterbore dimensions match this pin before installation. Do not force the pin into an undersized bore; resize or replace the bushing as needed to achieve proper fit and clearance.
