A single hopper is mounted on each extruder which is supported by a load cell. The throughput rate is determined from this signal and with an encoder suppling line speed the weight per length of material is calculated. Each extruder speed is adjusted to maintain the correct layer percentage plus the overall average thickness is controlled. Product memory up to 250 products and screw yield information included.
All throughput rates are available
Host computer/plc communications
Printer, shift/roll reports
Automatic shrink/stretch calculation of film
Trim scrap software for film.
Independent from bulk density of material
Shorter start-up, typically 2-3 minutes to be at target
Retrofit of all existing lines or for new installations
Fast return on investment, typically under 2 months
Considerable reduction of scrap produced
Increased production time due to faster start-up
Increase in yield by typically 4-5% of resin usage
Field proven experience has shown LRC systems to operate with an accuracy of +/-0.5% in average of better of the desired target.
