Manufacturers and buyers expect flawless products. Procedures for seamless quality management are therefore essential in every industry. Even the smallest defects, such as scratches, pores, dents, blowholes or impact marks in the surface can therefore lead to expensive complaints, safety defects, loss of function and even functional failures. If these are only detected later in the production process, they cause high costs. Complex geometric or safety- or function-critical components must also be manufactured reliably with consistently high quality in order to ensure that the company’s reputation is not damaged.
Higher quality thanks to automatic optical inspection
The inspection of very small components with different surface characteristics places high demands on the inspection process used: They should be highly productive and flexible with maximum quality, as well as inspect cost-efficiently and without interference. However, complex object geometries and a wide variety of material properties are increasingly placing limits on conventional optical inspection methods: If, for example, the surface structure of a test piece is irregular or its reflective characteristics fluctuate greatly, it is often no longer possible to reliably detect and evaluate defects. This increases the risk of defects on the one hand and the proportion of pseudo rejects in quality inspection on the other. For the manufacturer, additional downstream manual inspections result in additional costs that could be avoided with optimized systems. Advanced vision systems work quickly, precisely and objectively: based on optimized technologies, they provide exact information regardless of the surface quality of the test object – even with high inspection throughput and short throughput times.
