| Quality Measurement and Control Systems for Plastics Industry |
| |
Seltek Quality Measurement and Control Systems (QCS) are used for different applications in Plastics industry such as:
 Cast Film Lines
BOPP lines
Sheet extrusion lines
Foam production lines
These systems measure certain quality parameters of the plastic products on-line such as:
Total thickness
Layer thickness
Nucleonic, Infrared, x-ray, laser principles are used for design of these sensors. Measurements are non-contact type.
O-Frame is the most common scanner used. Single beam scanners and C-Frame scanners are also available.
Electronics enjoy a distributed architecture and the cabling between the frame and the main CPU is minimal, being restricted to Ethernet cable and power cable.
Machine Direction Controls as well as Cross Direction Controls are available. Depending on the line technology; gap control, extruder speed control, line speed control, Automatic Profile Control (APC) can be used.
HMI (Human Machine Interface) is operator friendly. Fast and slow trend plots, profile pages, recipe page, rich maintenance page, controls page, roll report page, alarm and event log pages are all very easy to learn and self guiding. Roll data is stored numerically in MS SQL® database, which can be converted to Excel® format for use by mill staff.
