Flex Films launches web metalised surface inspection system

By 24 Jul 2018

US-based Flex Films, the manufacturing arm of Noida-based Uflex, has developed an optical surface inspection technology and defect classification system called web metalised surface inspection system to reveal and quantify defects of its FlexMetProtect films. The system checks the entire web and allows for rapid and accurate detection of defects on the film. The inspection system is located in a strategic part of the slitting process just near to the winding roll comprised of smart, line-scan cameras that can analyse 100% of the web for defects in real time.

Deepak Mehta, technical manager at Flex Films (USA), said, “The web metalised surface inspection system will address any defect related to metal deposition such as the areas with high defect density or those having periodic defect or the ones with continuous defect and even contamination. The system measures and records the data in real time at very high web speed, generating a comprehensive report including mapping, defect characteristics like area, width, defect, light intensity, etc which helps the operator to address any quality related issues. This improves production efficiency and product quality and in-turn helps customers with less product wastage and downtime.”

Vijay Yadav, business head, Flex Films (USA), said, “The web metalised surface inspection system is designed for the inspection of non-patterned materials which are manufactured in continuous web processes. It performs the actual inspection and reports the inspection results that are reviewed prior to sending roll to the customer. It’s kind of a closed-loop system with slitting and metallising operations working in harmony to produce the best quality product, thereby assuring our customers of FlexMetProtect that the roll shipped to them is always of A-grade.”

Anantshree Chaturvedi, vice-chairman and CEO, Flex Films International, said, “This state-of-the-art web inspection system helps evaluate the entire web surface of FlexMetProtect generating a superior quality material that will give peace of mind to the customer and has the possibility to be used on AlOx coated transparent film too and we are in the process of acquiring new system to characterise bare film and we assure the quality of our product as always to our customers.

Ashok Chaturvedi, chairman and managing director, Uflex, said, “The good instincts of my engineers at Flex Films helped them acquire this new system of automatic defect monitoring which enables precise surface flaw detection and indeed makes it a commendable achievement.”
