Gibraltar MLP965-G Die Mold Leader Pin 1.249in Steel

Product Description

The GIBRALTAR MLP965-G is a die mold leader pin used to align mold halves during the closing cycle in injection molding and die casting operations. Machined from steel, this leader pin measures 1.249 inches in pin diameter and 2.75 inches in overall length (OAL). The head measures 1.49 inches in diameter with a head height of 5/16 inches. An OAL tolerance of +0.0000 / -0.0600 inches ensures controlled fit within the mold base. Toolmakers, mold builders, and die maintenance technicians install this component as part of mold alignment systems.

This leader pin is suited for use in die molds and injection mold bases where precise alignment between core and cavity halves is required. It is installed in the leader pin bushing bores of the mold base plates. Typical applications include production tooling in plastics processing and metal die casting facilities. The single-unit package quantity makes it straightforward to order as a direct replacement during mold repair or maintenance cycles.

Key Features

• 1.249-inch pin diameter for controlled fit in standard leader pin bushings
• 2.75-inch overall length with a tight OAL tolerance of +0.0000 / -0.0600 inches
• 1.49-inch head diameter and 5/16-inch head height for positive seating on the mold plate
• Steel construction for durability under repeated mold cycling loads
• Single-unit package quantity supports targeted replacement without excess stock

Compatibility

Designed as a direct-replacement die mold leader pin for mold bases requiring a 1.249-inch nominal pin diameter in this OAL range. Verify bushing bore diameter and plate thickness before installation.

Installation Notes

Installation is typically performed by a toolmaker or mold maintenance technician. Ensure the mold is fully de-energized, depressurized, and cooled before disassembly. The leader pin should be pressed or driven into the mold plate bore to the correct seating depth, with the head flush against the plate surface. Inspect the mating leader pin bushing for wear before installing a replacement pin.
