Gibraltar MLP970-G Die Mold Leader Pin 1.249in Steel

Product Description

The GIBRALTAR MLP970-G is a die mold leader pin used in injection mold and die tooling assemblies to align mold halves with precision during each press cycle. The pin measures 1.249 inches in pin diameter and 5.25 inches overall length (OAL), with a head diameter of 1.49 inches and a head height of 5/16 inch. The OAL tolerance is +0.0000 / -0.0600 inches, providing a close fit for consistent mold alignment. Constructed from steel, this leader pin is suited for production tooling environments where dimensional repeatability and wear resistance are required. Mold makers and tooling technicians are the primary installers.

This leader pin is designed for use in die mold assemblies, particularly in applications where precise guide alignment between the cavity and core halves is critical. It fits into standard leader pin bushings within injection mold bases. The MLP970-G is sold individually and is appropriate for both new mold builds and replacement of worn or damaged leader pins in existing tooling. It is well suited for production shops running thermoplastic or thermoset injection molding operations.

Compatibility

Designed as an OEM-style replacement leader pin for standard die mold bases requiring a 1.249 inch diameter guide pin with a 5.25 inch OAL.

Installation Notes

Installation is performed by mold makers or tooling technicians. Before replacing a leader pin, ensure the press is locked out and the mold is fully cooled and depressurized. Press or drive the pin into the leader pin retainer pocket using appropriate tooling — do not strike the head directly with a hammer without a brass drift or protective block. Verify the mating leader pin bushing for wear before reinstalling the mold into service.
