Surface inspection equipment

Surface defect inspection system automatically find the nonconforming product

With our surface defect inspection system, the product quality raised

We can inspect the front and back surfaces of the slit strip by setting a defect inspection system at the deflector roll, which is right after the slit cutter but before the recoiler.

We never ship out the nonconforming product that result from mother coil's surface defect
If the inspector observe the products by using eyes, the judgement may varies according to personal experience. However, it is possible to create a passing standard with the surface defect inspection system.
Ultimately, the yield rate improves
Product on hold usually come from the type of product that has strict quality specification. As a result, the yield rate become lower. We can provide information about the surface defect (such as blister, scratch, and etc.) so that the next coil processing can go on more smoothly.
Skip the coil inspection process
If the customer has to wind the coil in order just to inspect the defect, that step can be excluded.
