Gibraltar MEP1140-G Straight Ejector Pin 25mm Steel

Product Description

The GIBRALTAR MEP1140-G is a straight ejector pin designed for use in injection molds and progressive die tooling. It drives molded or stamped parts clear of the mold cavity at the end of each cycle. Machined from steel with a nitride finish, this pin delivers surface hardness and wear resistance suited to high-cycle mold environments. The pin measures 0.984 inches in diameter with a 1.260-inch head diameter, a 0.394-inch head height, and a 9.449-inch pin length for a 9.843-inch overall length. It is sized and finished for direct installation by toolmakers and mold maintenance technicians without secondary machining in standard applications.

This ejector pin is applicable to injection mold bases, compression molds, and transfer mold tooling in both production and prototype shop environments. The straight-pin geometry suits standard ejector plate systems where a uniform pin diameter along the full working length is required. The nitride finish reduces galling and extends service intervals compared to uncoated steel pins, making this pin suitable for medium- to high-volume production molds running abrasive or glass-filled materials.

Key Features

• Straight ejector geometry for standard ejector plate compatibility
• Steel construction with nitride finish for surface hardness and wear resistance
• 25 mm (0.984 inch) pin diameter for positive part ejection force
• 32 mm (1.260 inch) head diameter provides positive seating against ejector plate counterbore
• 250 mm (9.843 inch) overall length accommodates standard mold stack heights
• Single-piece package quantity supports individual replacement without overstocking

Compatibility

Designed as a direct-fit replacement straight ejector pin for injection mold and die tooling assemblies requiring a 25 mm pin diameter and 250 mm overall length with a 32 mm head diameter ejector plate seat.

Installation Notes

Installation is performed by toolmakers or mold maintenance technicians with the mold press locked out and at zero pressure per facility lockout/tagout procedures. Confirm ejector plate counterbore dimensions match the 32 mm head diameter and 10 mm head height before installation to ensure proper seating and flush fit. Do not force the pin into an undersized bore; light honing of the pin hole may be required to achieve proper sliding clearance. Verify pin length against mold stack height and ejector stroke before closing the mold.
