Gibraltar MT7673-G Straight Ejector Pin 3.5mm Steel

Product Description

The GIBRALTAR MT7673-G is a straight ejector pin used in injection molding and die casting tooling. It features a 3.5 mm pin diameter, a 315 mm overall length, and a nitride finish applied to a steel body. The nitride surface treatment improves hardness and wear resistance at the pin-mold interface, extending service life under repeated cycling. The 7 mm head diameter seats securely in the ejector plate, and the 3 mm head height provides proper retention without excessive stack height. Toolmakers and mold technicians install this type of pin during mold assembly or maintenance to replace worn or broken ejector pins in production tooling.

This ejector pin is suited for use in injection molds, compression molds, and die casting dies where a straight-style pin is specified. It fits applications requiring a 3.5 mm bore in the ejector system. The 312 mm pin length accommodates deeper mold bases and longer shut heights. This pin is typically selected during toolroom maintenance, mold repair, or new mold build-outs where standard straight ejector geometry is required.

Key Features

• 3.5 mm pin diameter for precise bore fitment in ejector plates and mold bases
• 315 mm overall length with 312 mm usable pin length for deep mold applications
• Nitride finish improves surface hardness and wear resistance at the mold interface
• Steel construction provides strength under cyclic ejection loads
• 7 mm head diameter and 3 mm head height for secure seating in standard ejector plates
• Single-piece straight ejector geometry for straightforward installation and replacement

Compatibility

Designed as a direct-replacement straight ejector pin for injection molds, compression molds, and die casting tooling requiring a 3.5 mm pin diameter and a 315 mm overall length in a standard straight ejector configuration.

Installation Notes

Ejector pin installation and replacement should be performed by a qualified toolmaker or mold technician with the mold fully de-energized, cooled, and secured in a safe working position. Verify bore diameter and ejector plate pocket dimensions before installation to confirm proper fit and prevent galling. Do not force the pin into an undersized bore. Inspect the ejector plate and retainer for wear or damage before reassembly.
