Gibraltar MEP1033-G Straight Ejector Pin 5.2mm 160mm Steel

Product Description

The GIBRALTAR MEP1033-G is a straight ejector pin designed for use in injection mold tooling and die applications. It features a 5.2 mm pin diameter, a 157 mm pin length, and a 160 mm overall length with a 10 mm head diameter and 3 mm head height. Constructed from steel with a nitride finish, this pin provides consistent dimensional accuracy and wear resistance under the repeated thermal and mechanical cycling typical of production molding environments. Moldmakers and toolroom machinists rely on this style of pin for part ejection in standard mold base configurations.

This ejector pin is suited for use in plastic injection molds, die casting tooling, and similar precision tooling applications where straight ejector pins are required for part release. The nitride surface treatment improves surface hardness and reduces galling at the pin-bore interface, extending service intervals in high-cycle molds. It is installed and maintained by moldmakers, tool and die technicians, and toolroom personnel working in production or job-shop environments.

Key Features

• 5.2 mm pin diameter for precise fit in standard ejector pin bores
• 160 mm overall length with 157 mm usable pin length
• 10 mm head diameter and 3 mm head height for positive retention in ejector plates
• Steel construction with nitride finish for improved surface hardness and wear resistance
• Straight ejector pin geometry for straightforward drop-in replacement or new mold build

Compatibility

Designed as a standard straight ejector pin for use in injection mold tooling and die applications requiring a 5.2 mm pin diameter and 160 mm overall length.

Installation Notes

Installation and replacement of ejector pins should be performed by qualified moldmakers or tool and die technicians with the mold fully de-energized, cooled, and safely supported in a press or on a workbench. Verify the ejector pin bore diameter and plate pocket dimensions before installation to ensure proper fit and clearance. Avoid forcing pins into undersized bores, as this can cause galling or bore damage. Follow shop safety protocols and applicable tooling standards when working on mold components.
