Thickness gauges for (flat-) film and sheet extrusion as well as automatic systems for extrusion-dies have been produced in Hollabrunn / Austria at SBI’s site since 1999.
Highly accurate, non-contact and radiation-free measuring devices are offered, which are used also for thickness control.
For thickness control, the thickness gauges are equipped with the necessary software for perfect thickness profile and hardware to control extrusion-dies.
Automatic systems for extrusion-dies:
Various control elements are available for equipping extrusion-dies with automatic systems. Some die manufacturers utilize SBI's systems to offer automatic extrusion-dies , but also existing extrusion-dies can be retrofitted
Inline thickness gauges for film and sheet extrusion:
SBI’s thickness gauges are accurate, non contact and free from radioactive sources for sensors. Because of its accuracy they are utilized for controlling extrusion-dies for thickness control in sheet extrusion.
KAPA I und KAPA II: capacitive system for films up to 3 mm thickness, as well as for sheet up to 6 mm.
KAPA IR: Thickness gauge for measurement of barrier layer, for thickness profile of an EVOH layer in a PP barrier sheet
SHADOW: direct measurement (not depending on sheet properties), for sheet up to 3,5 mm and more
STG: for rigid sheet up to 40 mm
Automatic system for extrusion-dies.
Various actuators are installed in SBI’s automatic systems, enables to move die-lip up to 2 mm
