Gibraltar MEP1100-G Straight Ejector Pin Steel Nitride

Product Description

The GIBRALTAR MEP1100-G is a straight ejector pin used in injection mold tooling to push finished parts out of the mold cavity at the end of each cycle. It features a 12.2 mm pin diameter, a 308 mm pin length, and a 315 mm overall length. The pin is machined from steel and finished with a nitride surface treatment that improves hardness and wear resistance at the contact surface. A 20 mm head diameter and 7 mm head height seat the pin securely in the ejector plate. This component is installed and maintained by moldmakers and tooling technicians in production and repair environments.

Straight ejector pins like the MEP1100-G are used in injection molding, die casting support tooling, and similar mold base applications where consistent, repeatable part ejection is required. They are common in both OEM mold builds and replacement tooling maintenance. The nitride finish makes this pin well suited for higher-cycle mold applications where surface wear is a concern. Tooling shops and mold maintenance teams keep standard-diameter ejector pins on hand for rapid turnaround during mold service.

Key Features

• 12.2 mm pin diameter for precise fit in standard ejector pin bores
• 308 mm pin length with 315 mm overall length including head
• 20 mm head diameter and 7 mm head height for positive ejector plate retention
• Steel construction provides strength and durability under cyclic loading
• Nitride finish increases surface hardness and extends service life
• Sold individually, with no minimum order above one piece

Compatibility

Designed as an OEM-style replacement or new-build component for standard ejector plate assemblies in injection molds and similar tooling that accept a 12.2 mm straight ejector pin.

Installation Notes

Ejector pins are installed by moldmakers or tooling technicians with the mold fully de-energized and hydraulic or pneumatic press circuits depressurized before disassembly. Pins must be seated fully in the ejector plate and backed plate to prevent movement during cycling. Verify bore clearance and pin-to-bore fit before closing the mold. Do not force or hammer a pin that does not slide freely, as this may indicate an undersized bore or contamination.
