Extrusion Asia Edition 1-2020

39 Extrusion Asia Edition 1/2020 ISRA VISION AG Industriestr. 14, 64297 Darmstadt, Germany www.isravision.com/de/ SMASH 提供前所未有的精细程度，可探测的最小划痕减小到 <10 µm SMASH provides a previously unattainable degree of precision in detection of smallest scratches down to <10 µm 对路产品的产量。第三，产品的性能得到全面监视，可从产 生缺陷的源头加以纠正。最后一点，工厂操作员可以有效地 进行产品变换，从而节约了成本。胶线、气泡、颜色偏差、 光畸变和划痕等缺陷全部都可以通过在线监测系统加以避 免。 在康得新的案例中，伊斯拉特别针对这个项目开发了一 套光学配置方案，并已被证实对客户非常有价值。康得新以 最佳化的成本实现了质量控制的所有目标，这得益于其经济 有效的解决方案：生产线短暂的调整时间和较低的废品率显 著提高了产品产量。 在现场，通过伊斯拉服务工程师的合作以及在来自德国 总部专家的协助下，系统顺利完成了安装。目前，生产人员 非常有效地使用着该系统。伊斯拉定期检查系统的状态，并 采纳客户宝贵的反馈意见，用于持续的性能改善和系统开 发。远程访问可以方便地向客户提供服务和进行快速调整。 胡先生对于系统的性能和良好的分类结果感到非常满 意，他说：“我们现在能够避免连续的缺陷，减少废料和在线 调整的时间。伊斯拉的 SMASH系统可以在线检测缺陷并精 确定位。它可以根据历史记录和数据统计，显示每天的产品 质量，并能根据数据立即进行调整。” 伊斯拉最近对系统进行了升级，从而获得了所能够实现 的最佳性能。 T he decision to integrate SMASH at the Zhangjiagang site, Jiangsu Province, was well-founded for KDX. The optical film branch works with the highest requirements for surface quality. For example, window film is used in the automotive or the construction sectors to reduce solar radiation. Even very tiny scratches affect the intended features of these products, which are cost-sensitive for customers. Both aspects account for a product that needs high-end inspection before it can be delivered and further processed. Therefore KDX identified the need to introduce a new inspec- tion system to improve quality. ISRA had been recommended to KDX by contacts and business partners in the industry as a glo- bally leading company of surface vision. Mr. Hu, the Production Director, said: “ISRA’s system can detect surface defects like small scratches in real-time and classify the shape and location of such defects. It replaces manual methods for inspection en- tirely, significantly increases the production efficiency, reduces the production cost, and ensures the film quality.” Mr. Hu ad- ded that competitors’ systems are often just able to detect eith- er scratches or parts of defects. ISRA’s SMASH is used for surface inspection of optical film and detects the defects in real-time. Four advantages can be identi- fied: First, the system, ensures that end customers receive only flawless material. Second, waste is reduced and the marketable production volume can be increased. Third, product properties are fully monitored and defect sources corrected. And last, plant operators can make product changes efficiently, thereby saving costs. Defects as glue line, bubbles, color deviations, light distortion and scratches can all be avoided with the inline inspection system. In the case of KDX, an optical configuration was developed by ISRA especially for this project and has proven to be very valu- able to the customer. KDX has reached all of its objectives in quality control at optimal costs due to the affordable and effi- cient solution: The short adjustment time of the production line and lower waste rate significantly increased output. With the cooperation on the on-site ISRA service engineers and additio- nal expert assistance from the Germany headquarters, as well as the initial maintenance support, the system set-up smooth. Today the manufacturing staff uses system very efficiently. ISRA checks the system status regularly and applies the customer’s valuable feedback for continuous performance refinement and system development. Remote access enables easy service and fast adjustments. “We are now able to avoid continuous defects, to reduce waste and in-line adjustment time. ISRA’s SMASH can detect the defects in-line and locate them precisely. It can show the product quality each day based on the history records and data statistics, which allow immediate adjustments,” Mr. Hu said about the very satisfying performance and the good classifica- tion results. Today, the technical department adjusts process parameters according to the data. ISRA upgraded the system recently, thereby the best possible performance.
