Molded Tool Steel Cavity
JB Tool, Die & Engineering, Inc. experienced mold makers and our state of the art machinery were what a plastics industry client was looking for when in need of a mold to produce a large diameter plastic closure. Our engineers worked closely with this client to design the precision mold.
The 70 mm mold cavity was made of H13 ESR tool steel to create the wide-mouth closure. Employing CNC turning and machining capabilities, we produced the 4-¼” diameter mold cavity that had a wall thickness of .045″ to .078″. The engraving was produced using our in-house EDM and high speed milling capabilities. To increase the wear life of the mold, a chromium nitride plus flash chrome finish was applied per the customer’s requirements.
Our die and mold making capabilities provide a custom service for design and manufacture. Please contact us today to learn more or refer to the table below.
