Among die and mold manufacturers, high-speed milling of hardened tool steel is one of the most important technologies. At JB Tool, Die & Engineering, Inc. we know how important it is and have the skill and experience to tackle the most complicated high-speed CNC milling projects. With this in mind, a plastics industry client came to JB Tool & Die for a core pin constructed from 440C stainless that would be used in the making of plastic closures.
Our design team created a CAD model as the basis for the manufacture of this forming pin. The process included CNC turning and machining, heat treatment and high-speed milling. We finished the 28 mm forming pin by polishing to a surface finish of 4 micro. The finished product measured 1-1/8″ diameter and we worked within tolerances of ± .0002″.
