What Is Mold Clamp Bolt Torque?

To understand mold clamp bolt torque, one needs to understand what torque is and how it is determined.

Torque is the stretching of the bolt and platen threads to maximize the strength of the fastener or mold clamp.

The mold clamp bolt torque will be much higher than the maximum torque requirements of the platen, so the machine torque specifications are important to follow. Often, mold setup engineers will have a false sense of security and will over tighten the mold clamp bolts believing the mold clamps will hold more weight. This is actually the opposite of what is occurring. The strength of the mold clamp declines when the bolt is torqued over the torque specification. The over-torquing of the mold clamp bolts strip the platen threads and actually raises the area around the threads and may cause the mold to sit unparalleled in the platen. Once you have over-torqued mold clamp bolt threads, the threads do not relax to the original condition. This is what causes Gaulding of the threads.
