Chill Roll & Winding Unit

Optical Control Systems (OCS) range of quality control products for the polymer industry.
OCS supplies customised and complete solutions in the fields of digital image processing, optical measurement and automation. The systems ensure maximum product quality control. With the aid of precision cameras in conjunction with high performance online image processing, the smallest defects in polymer products are detected, located and analysed in detail.

The applications for OCS systems range from laboratory use to complete integration into the production process.

The product range is extensive and covers the following areas:
Detection of gels and black specks in Pellets, Powder, Films (reflection / transmission mode) & Molten polymer
Extrusion systems
Chill-Rolls and winding units
FTIR Spectroscopy
Pellet size and shape distribution
On-Line haze measurement
• Fluorescent detection
Colour measurement
• Physical properties
