Gibraltar MLP969-G Die Mold Leader Pin Steel

Product Description

The GIBRALTAR MLP969-G is a die mold leader pin used to align mold halves during the closing and opening cycles of injection molds and die casting tooling. Machined from steel, this leader pin measures 1.249 inches in pin diameter with an overall length of 4.75 inches and a head diameter of 1.49 inches with a head height of 0.3125 inches. The OAL tolerance is +0.0000 / -0.0600 inches, providing controlled fit for repeatable mold alignment. Toolmakers and mold technicians install this component when building or refurbishing press tooling that requires precise pin-and-bushing guidance systems.

This leader pin is suited for use in injection mold bases, compression molds, and die casting tooling where accurate mold half alignment is critical to part quality and tooling longevity. The steel construction provides durability under repeated press cycles. It is sized for applications requiring a 1.249-inch diameter pin and is sold individually, making it practical for single-pin replacements as well as new tool builds.

Installation Notes

Installation is performed by qualified toolmakers or mold technicians during mold build or repair. Ensure the press or molding machine is fully de-energized and locked out before removing or installing leader pins. The leader pin should be pressed or driven into the mold plate bore to the designed seating depth using appropriate tooling to avoid damaging the head or bore surfaces. Verify pin and bushing clearances according to the mold design specifications before returning the tool to production.
