Calculate and Optimise Clamping Force

Resource-saving Production of Parts with iQ clamp control

Mould breathing is the basis for iQ clamp control. If this is too high or too low, defective parts can result from burners or burr formation. Wear in the mould is also a consequence. The intelligent iQ clamp control software calculates the optimal clamping force. Resource-saving production reduces the load on the machine and saves energy.

Up to 35%

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 for clamping force build-up can be reduced. This saves energy and cycle time.

Less wear

Using iQ clamp control protects the mould and the injection moulding machine. The mould needs to be serviced less often. The mould 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 through automatic impression taking

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

Reduce waste with automatic clamping force adjustment

If the clamping force is too high, burns may occur. If it is too low, burr formation may result. By automatically determining the mould 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 mould is required. Operation is simple, using the CC300 control unit of the injection moulding machine.

You want to calculate and set the clamping force intelligently?

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

How the Intelligent Clamping Force Calculation Works

In this video you can see how iQ clamp control calculates and optimises the clamping force based on mould breathing.

5 Steps to the Optimum Clamping Force
  1. Activate iQ clamp control directly via the CC300 control unit

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

  3. Set lower closing force limit as safety limit

  4. Start production

  5. Clamping force is calculated and set automatically.


  • Less scrap

  • Better surface quality

  • Energy savings

  • Less wear

What our Customers Say About iQ clamp control
Picture shows production manager at Dallmer Germany

With iQ clamp control, we increase the quality and reproducibility of our products. We can eliminate overmoulding and burr formation. Mould ventilation is improved and wear is reduced.

Andreas Föltz, Production Manager at Dallmer Germany
Customer interview: BIC about iQ clamp control

BIC uses the intelligent iQ clamp control software to calculate the optimum clamping force. A reduction in clamping force means less wear on the moulds and lower energy consumption, while the quality of the plastic components remains the same.

    Using Breathing Signals for Process Optimization

    Mold breathing provides useful information about the processes that occur in the mold and the cavity. Mold-maker Schneider Form and injection molding machine-maker ENGEL have recognized the potential which this process variable offers and have worked intensively on it for several years, albeit by adopting different approaches.
