PVB Film

Meet safety requirements by delivering only flawless products: With more than 25 years of experience in the inspection of PVB film and a large global market share, ISRA offers systems that accurately distinguish between surface characteristics and actual defects.

The systems reliably detect and classify even low-contrast defects that are virtually invisible to the human eye but are associated with high follow-up costs. The results are available in real time and allow operators to directly intervene in the manufacturing process and eliminate defect causes. This makes it possible to meet highest quality standards and achieve zero defects in customer deliveries. Additional benefits are waste reduction, curbing energy consumption and optimizing production processes in the long term.

The consistent documentation of all material properties is available over the entire life cycle of the production. 100% inspection and 100% documented quality guarantee the product safety. Additional tools support users in successfully conducting all relevant customer audits.

100% Inline Surface Inspection of PVB Film

The system is designed for the automatic inspection and specific requirements of all PVB materials. Important quality data is available online, offering a powerful tool for operators that allows them to minimize defect sources and reduce waste immediately. Only flawless material is delivered to customers.

Beyond Inspection Tools

ISRAs optional SMASH system add-ons deliver more than inspection: The Beyond Inspection Tools process the recorded inspection data and realize additional opportunities in optimization, validation, and data evaluation.

The following SMASH options achieve these potentials:

Full documentation of the entire surface area offers real-time information on material properties such as reflectivity and gloss. As a result, products like food or cosmetic packaging always meet the required quality specifications, eliminating costly customer complaints.

Verifying, optimizing and creating inspection recipes offline without having to shut down the production line reduces set-up times considerably, maximizing inspection efficiency and minimizing costs. The settings can be managed and standardized in a global and centralized manner, guaranteeing uniform quality specifications in every production line around the world.

Analysis of defect images and correct classification of all defects in predefined defect classes: Based on a wide variety of defect characteristics, this tool is an essential element in analyzing defects and their causes in the best possible way and preventing defects with minimal effort. The intuitive user interface helps operators to complete their tasks while ensuring that only flawless products are delivered to customers.

The software uses inspection data regarding the number and severity of defects, the quality of individual sections as well as the entire roll. It thereby classifies the roll condition according to various quality levels. This clearly indicates whether a roll meets the necessary specifications and can be delivered to the end customer.

The Rewind Manager enables users to control a rewinder with high precision, navigate accurately to surface defects such as insects or dirt spots, repair defects in a targeted way, and remove foreign particles. By turning waste into marketable products at low cost, you can improve your production yields and ensure customer satisfaction.

Calibration tools that can be integrated into the line quickly and easily, combined with dedicated software solutions. The ideal camera and lighting settings are checked and verified to ensure inspection results with increased repeatability.

Online validation tools for checking and documenting the correct function of the overall system: The software constantly monitors the accuracy of all geometric alignments and settings of the cameras, lighting, and parameters, even during the inspection process. 

Software for yield-boosting analysis of inspection data: The data can easily be prepared for statistical purposes, allowing you to create user-specific reports, e.g. in Excel.

Software solution designed to use inspection data to achieve maximum material yield: When calculating the ideal cut, the system also takes material distortion into account and automatically ejects only those areas identified as waste. It also ensures that the quality of the cut products can be easily matched to customer orders.

These two tools access both historic and current data and make it available for further analysis. They also allow users to monitor and modify inspection parameters. Multiple users can access the password-protected data simultaneously from various locations.
