Reference curve control
You can use the reference curve control feature of the SELOGICA control system to ensure consistent, optimum moulded part quality. The holding pressure is very precisely controlled on the basis of the pressure pattern in the mould. Influencing variables, such as viscosity variations in the melt, have less influence over part quality.
The principle of reference curve control is based on the idea of recording the internal mould cavity pressure characteristic of a moulded part deemed to be of good quality and employing this as a target characteristic. The adjustment characteristic of the controller is also documented.
- Consistent part quality thanks to a constant pressure characteristic in the mould during the holding pressure phase
- Significantly reduced number of start-up cycles
- Easy determination of target characteristics Convenient parameterisation of the controller
