Gibraltar MEP1021-G Straight Ejector Pin 3.2mm 400mm Steel

Product Description

The GIBRALTAR MEP1021-G is a straight ejector pin designed for use in injection mold tooling applications. Machined from steel with a nitride finish, this pin provides hardness and wear resistance suited to high-cycle mold operations. It measures 3.20 mm in pin diameter and 397 mm in pin length, with an overall length of 400 mm. The head is 6 mm in diameter and 3 mm in height, giving it a standard retained-head geometry compatible with common ejector plate configurations. Toolmakers, moldmakers, and mold maintenance technicians install this type of component during mold builds or ejector system rebuilds.

This ejector pin is suited for use in plastic injection molds, die casting tooling, and similar precision mold assemblies where controlled ejection of formed parts is required. The nitride surface treatment helps resist galling and premature wear in high-frequency cycle environments. It is appropriate for both production mold builds and repair applications where a standard straight ejector pin of this diameter and length is required.

Key Features

• 3.20 mm pin diameter for standard ejector plate fitment
• 397 mm pin length with 400 mm overall length for deep-draw mold applications
• 6 mm head diameter and 3 mm head height for retained-head ejector plate use
• Steel construction with nitride finish for hardness and wear resistance
• Straight ejector pin geometry for direct part ejection

Compatibility

Designed as a standard straight ejector pin for use in injection mold tooling assemblies requiring a 3.20 mm diameter retained-head pin with a 400 mm overall length.

Installation Notes

Ejector pins of this type are installed and serviced by moldmakers or toolroom technicians. The mold should be fully depressurized, cooled, and safely secured before any ejector system disassembly. Pins should be inspected for straightness and surface condition before installation, and the ejector plate bores should be cleaned and checked for proper clearance. Do not force a bent or oversized pin into the bore, as this can damage the mold plate.
