Gibraltar KEP-4518 Straight Ejector Pin 3/16 in 18 in Steel

Product Description

The GIBRALTAR KEP-4518 is a straight ejector pin used in injection mold tooling and die work to push finished parts out of a mold cavity after each cycle. It features a 3/16 inch pin diameter, an 18 inch overall length (OAL), and a 3/8 inch head diameter with a 3/16 inch head height. Machined from steel, this pin is built to withstand the repeated mechanical stress of high-cycle molding operations. It is a direct-replacement component for toolmakers, mold repair technicians, and machine shop personnel maintaining or rebuilding injection mold sets.

Straight ejector pins like the KEP-4518 are used in plastic injection molds, die casting tools, and stamping dies across both job shop and production environments. The 18 inch length suits deeper mold bases where standard shorter pins would not reach the parting line. This pin is sold individually and is appropriate for maintenance, emergency tooling repair, or new mold builds requiring off-the-shelf ejector components.

Key Features

• 3/16 inch (0.1875 inch) pin diameter for precision fitment in standard ejector pin bores
• 18 inch overall length suits deep mold bases and long-reach ejection applications
• 3/8 inch head diameter with 3/16 inch head height for positive seating in ejector plates
• Steel construction provides durability under high-cycle mechanical loading
• Sold as a single unit for targeted replacement without excess inventory

Compatibility

Designed as an OEM-style replacement straight ejector pin for use in standard injection mold, die casting, and stamping tooling applications that accept a 3/16 inch diameter ejector pin.

Installation Notes

Ejector pin replacement is typically performed by a toolmaker or mold technician with the mold fully removed from the press and all hydraulic or mechanical clamping pressure relieved. The ejector plate must be disassembled to seat the head of the pin correctly before reassembly. Inspect the ejector pin bore for wear or damage before installing a new pin, as an oversized or scored bore will cause premature pin failure. Follow your facility safety procedures for handling heavy mold components during disassembly.
