Gibraltar MLP903-G Die Mold Leader Pin 0.5 in Steel

Product Description

The GIBRALTAR MLP903-G is a die mold leader pin engineered for precision tooling and mold alignment applications. It features a 0.5 inch pin diameter, an overall length of 3.25 inches, and a head measuring 0.625 inches in diameter by 0.1875 inches in height. Constructed from nickel chromium molybdenum steel, this leader pin delivers the hardness and wear resistance required in high-cycle die and mold operations. It is a standard component used to guide and align mold halves during the press cycle, maintaining precise registration between mold components. Toolmakers, die setters, and mold technicians install and service these pins during mold building or maintenance operations.

This leader pin is suited for use in injection molds, compression molds, and progressive die sets where repeatable alignment is critical. It is installed in the leader pin bushing or guide bushing of a mold base to ensure consistent part-to-part registration. The 0.5 inch pin diameter and 3.25 inch overall length make it appropriate for medium-frame mold bases in both production and prototype tooling environments.

Key Features

• 0.5 inch pin diameter for standard medium-frame mold base fitment
• 3.25 inch overall length accommodates typical mold plate stack heights
• 0.625 inch head diameter by 0.1875 inch head height for positive seating against the mold plate
• Nickel chromium molybdenum steel construction provides high hardness, toughness, and wear resistance
• Single-piece solid pin design for consistent dimensional accuracy

Compatibility

Designed as a standard OEM-style replacement or new-install leader pin for die and mold bases requiring a 0.5 inch pin diameter guide component.

Installation Notes

Installation is performed by qualified toolmakers or die technicians. Ensure the press or molding machine is fully de-energized and locked out before accessing the mold base. The leader pin is typically pressed or slip-fit into the mold plate bore to the appropriate interference or clearance specification for the mold base design. Inspect the corresponding leader pin bushing for wear before installing a new pin to avoid premature wear or misalignment.
