Clamping Force Calculation and Optimization

Resource-efficient Production of Parts with iQ clamp control

Mold breathing is the basis for iQ clamp control. If this is too high or too low, parts will show injection molding defects like burns or burrs. Mold wear is also a consequence. The intelligent iQ clamp control software calculates the optimum clamping force. Resource-saving production reduces the load on the machine and saves energy.

Up to 35%

Less Clamping Force

Advantages of the Optimal Clamping Force Calculation
Save energy

iQ clamp control reduces the clamping force to the minimum required while maintaining optimum part quality. This means that the drive energy needed to build up the clamping force is reduced. This saves energy and cycle time.

Less wear

Using iQ clamp control protects the mold and the injection molding machine. The mold requires less frequent maintenance. The mold quality remains constant, and repeated manual readjustment is no longer necessary. Your maintenance costs decrease and productivity increases due to extended production intervals.

Better surface quality thanks to automatic impression taking

Especially with highly polished cavities, it is important to work with optimum clamping force, as the flow lines are less visible. If you depend on very high impression accuracy, our iQ clamp control software is the ideal solution for clamping force calculation.

Reduce scrap by automatic clamping force adjustment

If the clamping force is set too high, burns may occur. Too low a clamping force may lead to burr formation. By automatically determining mold breathing, the clamping force is calculated and set in the best possible way. Scrap is significantly reduced.

No additional costs for equipment or training

iQ clamp control calculates the correct clamping force fully automatically, regardless of the operator's experience. Neither additional measuring equipment on the machine nor additional sensor technology on the mold is required. Operation is simple, the software is integrated in the CC300 control unit of the injection molding machine.

You want a smart way to calculate and set the clamping force?

Our experts will be happy to answer any questions you may have about clamping force optimization.

How the Smart Clamping Force Calculation Works

In this video you will see how iQ clamp control calculates and optimizes the clamping force based on mold breathing.

Video shows how the intelligent clamping force calculation works >
5 Steps to the Optimized Clamping Force Settings
  1. Activate iQ clamp control directly on the CC300 control unit

  2. Reference curves are determined at the touch of a button

  3. Set lower clamping force limit as safety limit

  4. Start production

  5. Automatic clamping force calculation and settings


  • Less scrap

  • Better surface quality

  • Energy savings

  • Less wear
