Switching from Solid Carbide to Indexable Tooling Permits Lights Out Mold Base Manufacturing
Since 1965, Craftsman Tool & Mold has specialized in creating large, close tolerance, complex, high precision, custom mold bases for the aerospace/defense, appliance, automotive, computer/business equipment, electronics/electrical, hydraulic/pneumatic/controls, lawn and garden, medical/optical/dental, telecommunications, toys/recreational/sporting goods industries. Its 50-person team focuses mainly on stack mold bases and rotational spin stack mold bases for the multi-shot plastic injection mold industry across North and South America. Other services include large-capacity gun drilling, Grinding, CNC Milling, die sets, bolster plates, and specialty machining.
According to Jason Long, Craftsman Tool & Mold product manager, the team needed a solution to create small, deep pockets in its large mold bases. They were using solid carbide mills, which resulted in repeated breakage issues. On top of that, given the unreliability of the cutters, Long was extremely reluctant to allow unattended machining. The shop always had an operator at the machine to monitor progress, adding an expense for each project.
