Gibraltar HEP3519-G Shoulder Ejector Pin 1/16 in Steel

Product Description

The GIBRALTAR HEP3519-G is a shoulder ejector pin designed for use in injection mold tooling and die sets. This pin features a 1/16 inch pin diameter, an overall length of 10 inches, and a nitride finish applied to hardened steel for improved wear and corrosion resistance. The shoulder design provides a positive stop at the mold plate, keeping the pin precisely located during repeated ejection cycles. Toolmakers and mold maintenance technicians install this type of component when rebuilding or replacing worn ejector pin sets in production molds.

This shoulder ejector pin is suited for use in plastic injection molds, die casting tooling, and stamping dies where controlled pin positioning is required. The 1/8 inch shoulder diameter and 2 inch shoulder length allow the pin to seat in standard ejector retainer plates. With an 8 inch pin length and 1/4 inch head diameter, this part fits applications requiring a longer reach from the ejector plate to the mold parting surface. It is sold individually and is appropriate for both new mold builds and maintenance replacement work in a shop environment.

Key Features

• Shoulder ejector pin design provides positive seating in ejector retainer plates
• 1/16 inch pin diameter with 8 inch pin length for deep-reach ejection applications
• 1/4 inch head diameter and 1/8 inch head height for standard retainer plate pockets
• 1/8 inch shoulder diameter with 2 inch shoulder length for secure plate registration
• Nitride finish on steel construction for enhanced surface hardness and wear resistance
• 10 inch overall length accommodates thicker mold base configurations

Compatibility

Designed as an OEM-style replacement or new-build component for injection mold ejector systems requiring a shoulder ejector pin with a 1/16 inch pin diameter and 10 inch overall length.

Installation Notes

Shoulder ejector pins are installed and replaced by toolmakers and mold technicians during mold maintenance or rebuild operations. Before servicing an ejector system, disconnect all hydraulic, pneumatic, and electrical connections to the press and relieve any stored energy in the ejector mechanism. Pins should be checked for straightness and fit in the ejector plate bore before installation to avoid binding or premature wear. Consult the mold design drawings to confirm pin diameter, shoulder dimensions, and overall length before replacing components.
