Gibraltar MEP1130-G Straight Ejector Pin 20mm 630mm Steel

Product Description

The GIBRALTAR MEP1130-G is a straight ejector pin used in injection mold tooling to push finished parts free from the mold cavity at the end of each cycle. Machined from steel with a nitride finish for surface hardness and wear resistance, this pin measures 20 mm in diameter with a 622 mm pin length and a 630 mm overall length. The 26 mm head diameter and 8 mm head height seat against the ejector plate, keeping the pin properly located during repeated actuation. Mold makers and tooling technicians specify this pin for high-cycle production molds where dimensional consistency and surface durability are critical.

This ejector pin is suited for use in plastic injection molds, die casting tooling, and similar mold base assemblies that require a straight ejector pin in the 20 mm diameter class. The nitride surface treatment improves hardness without significantly altering finished dimensions, making this pin a direct fit for standard ejector pin bores in mold bases. It is appropriate for both new mold builds and replacement of worn or damaged pins in existing tooling.

Key Features

• Straight ejector pin geometry for standard mold base ejector plate assemblies
• 20 mm pin diameter with close-tolerance ground finish for accurate bore fit
• 622 mm pin length provides extended reach for deep-draw or tall mold configurations
• 26 mm head diameter and 8 mm head height for positive seating in ejector plate counterbores
• Nitride finish increases surface hardness and wear life in high-cycle applications
• Steel construction resists deflection under ejection loads

Compatibility

Designed as a standard straight ejector pin for use in injection mold bases and tooling assemblies requiring a 20 mm diameter straight ejector pin with a 630 mm overall length.

Installation Notes

Installation is performed by mold makers or tooling technicians during mold build or maintenance. Confirm bore diameter and ejector plate counterbore dimensions match the pin head specs before assembly. Ensure the mold is fully de-energized, cooled, and secured before removing or installing ejector pins. Do not force the pin into an undersized bore; verify fit and alignment before pressing into final position.
