Gibraltar MT7718-G Straight Ejector Pin 10mm 250mm Steel

Product Description

The GIBRALTAR MT7718-G is a straight ejector pin used in injection mold tooling to push finished parts out of a mold cavity at the end of each cycle. Machined from steel with a nitride finish, this pin measures 10 mm in diameter and 250 mm in overall length, with a 245 mm pin length and a 16 mm head diameter. The nitride surface treatment improves hardness and wear resistance at the pin face and along the shaft, extending service life under repetitive ejection cycles. Mold makers, toolroom machinists, and mold maintenance technicians are the primary installers.

This ejector pin is suited for use in plastic injection molds in both production tooling and prototype tooling environments. It is sized for applications requiring a 10 mm bore in the ejector plate and retainer plate assembly. The 5 mm head height allows proper seating against the ejector retainer plate. Typical applications include residential and commercial mold shops running thermoplastic parts where consistent, repeatable ejection is required.

Key Features

• 10 mm pin diameter for compatibility with standard 10 mm ejector pin bores
• 250 mm overall length with a 245 mm working pin length
• 16 mm head diameter and 5 mm head height for positive retention in ejector plate assemblies
• Steel construction with nitride finish for improved surface hardness and wear resistance
• Straight ejector pin profile for direct, vertical part ejection

Compatibility

Designed as a standard straight ejector pin replacement for injection mold tooling requiring a 10 mm pin diameter and 250 mm overall length. Confirm ejector plate bore diameter and retainer plate pocket dimensions before installation.

Installation Notes

Installation is performed by mold makers or toolroom machinists during mold assembly or preventive maintenance. The mold must be fully de-energized, cooled, and removed from the press before ejector plate disassembly. Pins should be inspected for straightness before installation, as a bent pin can cause galling in the bore or incomplete part ejection. Refer to the mold design specifications to confirm pin length, head seating depth, and ejector stroke clearance.
