TSM Control Systems

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 & Benefits:

- 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
