For the first time, the all new BLANKING MASTER is able to precisely detect and classify surface defects on blanking parts.  The illumination from two sides, transmission for contour shape recognition and reflection for defect recognition, enables defect detection just within the mold. An initially preconfigured and at the same time adaptive software reliably detects and classifies all defects such as scratches, roll impressions, and scores. Surface inspection after cutting the preforms reduces costs and increases yield: Information on the actual quality of the product avoids unnecessary safety downgrades.

A BLANKING MASTER system usually pays for itself within weeks.

Constant Pass-Line distance technology is an add-on to the SURFACE MASTER that allows inspection at the coiler, often the only available inspection position. The sensor maintains a constant distance to the inspected surface during the entire winding or unwinding process. This is the only way to ensure reliable inspection with a changing diameter of the coil.

The slab is highly structured and has a temperature of around 1,000°C. Nevertheless, the SLAB MASTER can detect defects that would be invisible to contrast-based 2D inspection technology.

Based on laser triangulation, the 3D inspection system detects and classifies all relevant defects, such as cracks or inclusions. It also measures their depth on the top, bottom and sides of the slab. Automatic surface inspection begins from the first production step, ensuring that only flawless material is transferred to downstream processes.

The ISRA  InstantClassifierTM includes over 80% of all typical defect classes with its standard installation.

In addition to identifying surface defects, the inspection system calculates the size (volume and weight) of the slab.

A SLAB MASTER system typically has a payback period of just a few weeks.
