Gibraltar MEP1133-G Straight Ejector Pin 9mm 160mm Steel

Product Description

The GIBRALTAR MEP1133-G is a straight ejector pin designed for use in injection mold tooling and die sets. It provides a consistent, repeatable push force to eject formed parts from a mold cavity at the end of each press cycle. Machined from steel with a nitride finish for surface hardness and wear resistance, this pin measures 9 mm in diameter with a 155 mm pin length and a 160 mm overall length. The head measures 14 mm in diameter and 5 mm in height, seating securely in the ejector plate. Toolmakers and mold technicians specify this style of pin for high-cycle production molds where dimensional consistency and finish durability matter.

This ejector pin is suited for use in plastic injection molds, die casting tooling, and stamping die sets where a straight ejector pin configuration is required. It is a direct-fit replacement or new-build component for mold bases that accept a 9 mm pin diameter with a flat-head retention style. Typical installation environments include production machine shops, moldmaking departments, and tool-and-die facilities operating conventional or CNC-controlled press and injection equipment.

Key Features

• Steel construction with nitride finish for surface hardness and extended service life in high-cycle mold applications
• 9 mm pin diameter for consistent fitment in standard ejector plate bores
• 155 mm pin length with 160 mm overall length for adequate ejection stroke in medium-depth mold cavities
• 14 mm head diameter and 5 mm head height for positive retention in ejector plate counterbores
• Straight ejector pin profile — no taper or angle — for straightforward installation and alignment

Compatibility

Designed as an OEM-style replacement or new-build component for injection molds and die sets requiring a straight ejector pin with a 9 mm pin diameter and a 160 mm overall length with a flat retention head.

Installation Notes

Ejector pins are installed and replaced by toolmakers or experienced mold technicians. Always power down and lock out the press or injection molding machine before accessing the mold base or ejector assembly. Ensure the bore diameter in the ejector plate and the mold core is clean and free of debris before inserting the pin. Pins should slide freely without binding; forced installation can cause pin breakage or mold damage during operation.
