IMS CCS Pinhole Detection System Metal Service Centres


Pinhole Detection System

The IMS pinhole detection system is ideal as high-performance solution especially for rolling mills and processing lines (e.g. for aluminum, copper and steel).

The measurement method is based on the detection of finest quantities of light by CMOS photo sensors. In this way, the CCS pinhole detector reliably detects, locates and classifies even the smallest perforations that can occur in the production of strips and foils.

Dipl. Engineer

…to the verifiability of flatness previously required, your best customer suddenly also needs the exact geometry of the plates to be delivered. Do you now lose the order or is there a possibility to retrofit a measuring system despite the cramped conditions? What advantage does this investment bring me, apart from the fact that it satisfies just this one customer?

Not only in slitting and cut-to-length lines, but also in pickling lines, recoiling lines and inspection lines, it is necessary to meet growing customer demands on product quality. These are challenges that I am confronted with every day and for which we at IMS have developed a product portfolio specially tailored to metal service centres.

We set new standards with our systems and reach new dimensions with our efficient, digital and durable measurement technology. The systems are designed precisely for your application, and with our Life Cycle Partnership you are always on the safe side.”
