What kind of defects does Helmee CSD® can find?
1. Various types of defects
Helmee CSD® can detect two kinds of defects mainly. First ones are defects influencing the reflection on the surface. If glossiness or reflectiveness is missing from the surface, it is possible to detect them, because Helmee CSD® technology detect defects by looking at reflection from the surface. For example, scratch, dot, missing coating, pinholes, spot, pore and burn mark type of defects in below are representative of these defects.
Another one is defects influencing shape of the surface. Helmee CSD® has various kind of image channels developed by Helmee specialists and they allow us to see shape changes on the surface. Dent, grain and bubble type of defects in below image are typical defects having shape.
These defect types are just examples, Helmee CSD® can find more. Sometimes our customers introduce new type of defects, this is how we are motivated to develop our technology. Thanks to our customers and skillful specialists, Helmee CSD®’s capability is growing rapidly.
2. Detectbale defects size
Usually OEMs in automotive industry set the inspection criteria for their suppliers. For instance, OEMs demand suppliers to keep biggest defects less than 0.3mm2. Helmee CSD® can detect 0.03mm2 size of defects whereas human eye can find 0.01mm1. However, finding small defects from reflective parts make human eyes tired. Because of this, human eye inspection outcome is usually not stable, and accuracy is not high compare to machine vision systems like Helmee CSD®.
Our customers have reported 80% accuracy on average per inspector.
Helmee CSD® has typically accuracy of more than 95%.
Hübner GmbH is a German company that manufactures decorative plated plastic parts with a high gloss surface. They offer their clients the whole production chain from the planning phase to assembly and all the way through final quality inspection. They promise their clients high-quality high gloss products and use certified and documented process chains. After finding Helmee's CSD®, they have been able to further improve both their quality control as well as their documentation.
– Before we had the Helmee CSD®, we inspected the plated parts manually. It is a very tiring and monotonic task, which has now been automated, explains David Renger, the Production Director at C. Hübner GmbH.
