Dayton Lamina Ljb 75 300 Ejector Mold Die Blank

Product Description

The DAYTON LAMINA LJB 75 300 is an ejector mold die blank designed for use in injection mold and die tooling applications. It features a 0.75-inch shank diameter, a 31/32-inch machinable length, and a 3-inch overall length (OAL), making it a precision component suited for mold base assemblies. Constructed from A2 tool steel, this blank delivers the hardness and dimensional stability required for demanding toolroom and production environments. A 1/16-inch pin extension length and ball lock retention style are built into the design. Toolmakers and mold technicians are the primary installers of this component.

This ejector die blank is applicable in plastic injection mold assemblies where ejector pin systems require a standardized, machinable blank for custom fitting. The ball lock configuration allows secure retention within the mold base. The A2 tool steel construction supports use in both prototype tooling and production mold sets where wear resistance and machinability are priorities. It is suited for shops building or maintaining single-cavity and multi-cavity mold configurations.
