Thickness Profiling
The TSM film thickness profiling system fitted to your blown film extrusion line will provide a real time read out of film thickness profile, allowing timely action to ensure product consistency.
Features & Benifits:
- Economical concept to increase productivity while reducing scrap, saving resin and improving product quality
- Measurement is only made when film has cooled to ambient temperature so the system measures exactly what the customer is paying for
- No contact with film, therefore no scratching
- On-spec film thickness increases customer and end user satisfaction
- On-spec film thickness improves print consistency
Operational Description:
- The Thickness Profiling System measures the film at the edge of the lay-flat film
- The film glides through the spacing between two electrodes without making contact
- The blown film thickness is determined by measuring the capacitive changes that occur in the space between the electrodes as the film glides through
- An electronic signal corresponding to the capacitive changes is transmitted to the process control as a thickness profile
- This profile can be correlated to the die bolts of the extruder by taking into account the rotation and zero position of the blown film line
- To cope with fluctuating film edge position, the option of an automatic edge positioning device is available to ensure measurement consistency. It also allows automatic reset to zero at regular intervals
