Gibraltar HEP3508-G Shoulder Ejector Pin 3/64 in Steel

Product Description

The GIBRALTAR HEP3508-G is a shoulder ejector pin designed for use in injection molds and die casting tooling. It features a 3/64-inch pin diameter, a 1/4-inch head diameter, and an overall length of 6 inches with a 4-inch pin length. The pin is machined from steel and finished with a nitride treatment, which improves surface hardness and wear resistance. The shoulder design provides a precise fit in the ejector plate, maintaining alignment during repeated cycling. This pin is installed by toolmakers and mold technicians during mold assembly or repair operations.

This ejector pin is suited for plastic injection mold ejector systems in both prototype and production tooling environments. The 1/8-inch shoulder diameter and 2-inch shoulder length allow it to seat securely in the ejector retainer plate. It is well-suited for applications requiring tight dimensional control in high-cycle mold tooling where standard straight ejector pins are not appropriate.

Key Features

• Shoulder ejector pin design for precise ejector plate seating and alignment
• 3/64-inch pin diameter with 4-inch pin length for targeted part ejection
• 1/4-inch head diameter and 1/8-inch head height for proper retention
• 1/8-inch shoulder diameter and 2-inch shoulder length for secure fit in retainer plate
• Steel construction with nitride finish for improved hardness and wear resistance
• 6-inch overall length accommodates standard mold base configurations

Compatibility

Designed as an OEM-style replacement or standard component for injection mold ejector systems requiring a shoulder ejector pin with a 3/64-inch pin diameter and 6-inch overall length.

Installation Notes

Installation is performed by qualified toolmakers or mold technicians. Power down and lock out all press and mold equipment before accessing the ejector assembly. Verify that the ejector retainer plate bore matches the shoulder diameter and that the ejector plate pocket is the correct depth to accept the head height before pressing the pin into position. Do not force-fit pins into undersized bores, as this can cause plate damage or pin failure during cycling.
