Gibraltar MLP994-G Die Mold Leader Pin 1.5 in Steel

Product Description

The GIBRALTAR MLP994-G is a die mold leader pin manufactured from nickel chromium molybdenum steel for high-strength, wear-resistant performance in mold and die tooling applications. The pin measures 1.5 inches in diameter with an overall length of 6.25 inches. The head is 1.75 inches in diameter and 0.3125 inches tall, providing a secure seating surface within the mold base. At 3.26 pounds, this is a solid, precision-ground component intended for installation by tool and die makers, mold technicians, and industrial maintenance professionals working on injection molds, die cast tooling, and stamping dies.

Die mold leader pins are used to align mold halves during the closing cycle, maintaining precise registration between the cavity and core sides of the mold. The MLP994-G is suited for medium-to-large mold bases where a 1.5-inch leader pin diameter is specified. It is a direct replacement or spare component for production tooling in plastics injection molding and metal die casting environments. Tool rooms and mold shops stock leader pins of this size for scheduled maintenance and emergency repair situations.

Key Features

• 1.5-inch pin diameter for medium-to-large mold base fitment
• 6.25-inch overall length accommodates deeper mold base configurations
• 1.75-inch head diameter with 0.3125-inch head height for positive mold plate seating
• 3.26-pound solid construction supports heavy-duty tooling environments

Compatibility

Designed as an OEM-style replacement or spare leader pin for die and mold bases requiring a 1.5-inch diameter leader pin with a 6.25-inch overall length.

Installation Notes

Die mold leader pins are installed by qualified tool and die makers or mold technicians. The mold should be fully de-energized, cooled, and separated from the press before replacing any leader pin. Proper fit between the leader pin and bushing is critical to mold alignment; inspect the corresponding leader pin bushing for wear before installation. Do not force-fit the pin into the mold plate — consult the mold base manufacturer specifications for press-fit or slip-fit tolerances.
