High return on investment in the cost-intensive production of stretch films: ISRA inspection systems ensure high throughput rates and maximum quality in production lines, while also preventing extended production downtimes and shortening start-up times following product changes.
Our systems are suitable for use at the beginning of the process directly after extrusion, where they prevent web breaks in downstream production steps by eliminating quality-related defects. In addition, they can be used after stretching or in between stretching sections to ensure the desired end product quality. They reliably detect defects such as scratches, gels and contamination, even at maximum web speeds.
Reports and data analyses can be generated on each daughter roll based on the inspection data generated, making it possible to ensure the specified quality in accordance with individual customer requirements or to reject defective material prior to delivery.
100% Inline Surface Inspection of Stretch Film
The system is designed to inspect transparent, opaque, translucent, colored and colorless materials automatically. By providing real-time information about material properties, it offers a quick and cost-effective alternative to elaborate and time-consuming laboratory tests. The data obtained enables you to meet all customer requirements reliably and remain confident when it comes to potential customer complaints.
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.
