Gibraltar MT7685-G Straight Ejector Pin 4.5mm 200mm Steel

Product Description

The GIBRALTAR MT7685-G is a straight ejector pin designed for use in injection mold tooling applications. It features a 4.5 mm pin diameter and a 200 mm overall length, making it suitable for a range of standard mold configurations. Constructed from steel with a nitride finish, this pin offers surface hardness and wear resistance suited to high-cycle mold operation. The head measures 8 mm in diameter and 3 mm in height, with a pin length of 197 mm. Mold technicians and tool-and-die professionals install this component during mold builds or maintenance cycles.

This ejector pin is used in plastic injection molds where straight-pin ejection is required to push molded parts from the cavity. It fits mold bases that accept standard straight ejector pin configurations. Typical installation environments include production toolrooms, mold shops, and on-site mold repair settings. The nitride surface treatment helps extend service life in abrasive or high-temperature mold conditions. Sold individually, this pin is suitable for single-position replacement or new mold builds.

Installation Notes

Ejector pins are installed and replaced by mold technicians or tool-and-die professionals. Power down and de-energize the molding machine and release any hydraulic or pneumatic pressure before accessing the ejector assembly. Pins should be checked for proper fit and free movement in the ejector plate before returning the mold to service. Consult applicable toolroom safety procedures and machine manufacturer guidelines during mold disassembly and reassembly.
