Gibraltar MEP1041-G Straight Ejector Pin 5.5mm 315mm Steel

Product Description

The GIBRALTAR MEP1041-G is a straight ejector pin used in injection mold tooling to push finished parts out of a mold cavity after each cycle. It features a 5.5 mm pin diameter, a 315 mm overall length, and is manufactured from steel with a nitride finish for hardness and wear resistance. The head measures 10 mm in diameter and 3 mm in height, providing a positive seating surface against the ejector plate. This pin is a standard component installed and maintained by toolmakers and mold technicians in production tooling environments.

Straight ejector pins are used across a wide range of injection molding applications, including thermoplastic and thermoset mold tooling in both production and prototype environments. The 5.5 mm pin diameter and 312 mm pin length make this pin appropriate for deeper mold cavities requiring extended reach. It is suited for use in molds requiring precise, repeatable ejection of molded parts with minimal gate or surface marking.

Key Features

• 5.5 mm pin diameter for precise fitment in corresponding mold bore
• 315 mm overall length with 312 mm usable pin length for deep-cavity applications
• Nitride finish provides surface hardness and corrosion resistance for extended service life
• 10 mm head diameter with 3 mm head height for positive retention against ejector plate
• Steel construction withstands repeated ejection cycles under high clamping and ejection loads

Compatibility

Designed as a standard straight ejector pin for use in injection mold tooling requiring a 5.5 mm pin diameter and 315 mm overall length with a nitrided steel finish.

Installation Notes

Installation should be performed by a qualified toolmaker or mold technician with the mold fully removed from the press and all hydraulic or mechanical ejection systems fully de-energized and locked out. The pin bore in the ejector plate and mold plate should be checked for diameter tolerance and alignment before installing the replacement pin. Refer to the mold design drawings for correct pin placement and ejector plate travel limits. Do not modify pin length by grinding unless the head-to-pin geometry is verified against the original mold specification.
