Gibraltar BW8632-G Die Mold Sprue Bushing Series B

Product Description

The GIBRALTAR BW8632-G is a Series B die mold sprue bushing machined from steel, designed for use in injection mold and die casting tooling applications. It features a 1-inch shank diameter with a shank length of 3-29/32 inches, a 2-inch head diameter, and an overall length of 4-25/32 inches. Additional dimensional details include a 7/8-inch head height, a 7/32-inch hole diameter, a 3/16-inch cavity depth, and a 3/4-inch corner radius. Mold technicians and toolmakers install this bushing to guide and channel molten material into the mold cavity during the injection or die casting cycle.

This sprue bushing is suited for production tooling environments where consistent gate geometry and reliable material flow are required. It is appropriate for use in both prototype and high-volume production molds. The steel construction provides the hardness and wear resistance needed to withstand repeated injection cycles. Toolmakers working with standard Series B mold bases will find this bushing dimensionally consistent with that system family.

Key Features

• Series B designation for compatibility with standard mold base configurations
• Steel construction for durability and resistance to wear under repeated cycling
• 1-inch shank diameter with 3-29/32-inch shank length for secure mold seating
• 2-inch head diameter with 7/8-inch head height for positive locating surface
• 7/32-inch hole diameter and 3/16-inch cavity depth for defined gate geometry
• 3/4-inch corner radius for smooth material transition at the sprue entry

Compatibility

Designed as an OEM-style replacement sprue bushing for Series B mold base tooling applications in injection molding and die casting setups.

Installation Notes

Installation is performed by qualified mold technicians or toolmakers. The mold must be fully disassembled and all hydraulic or injection pressure relieved before bushing removal or installation. Standard mold-making hand tools and a press may be required to seat the bushing properly. Verify dimensional fit against the mold plate bore before pressing to avoid damage to the mold or bushing.
