Optical Surface Inspection
The surface quality of a product - particularly in the automotive industry - constitutes an important criterion for the customer and is generally seen in close relation to the quality of the overall vehicle.Even inevitable disturbances at the early production stages prior to applying the paint work (e.g. in the press shop or body shop) may cause defects such as dents, bumps, sink marks, etc. which might not be visible to the eye while the vehicle is still unpainted.
ABIS IIWith its enhanced contrast sensor system, ABIS II quickly, reliably and ultra accurately detects 3D defects and contrast-sensitive defects on the inspected parts. |
ABISreflectABISreflect is a compact optical inspection system for the reliable and accurate quality assurance of glossy and reflective surfaces. |
On a glossy paint surface, however, even the slightest irregularities are clear to see with incident light from the proper angle, and constitute a reduction in quality. Particularly the intense competition among manufacturers demands an increase in the surface quality in conjunction with continuously decreasing production costs. The target freedom from defects is time-consuming and labor-intensive to achieve for automobile manufacturers.
It is not 100 % possible through conventional means so that defects that have gone unnoticed during the production process generate very high rework costs. Now, the early and complete detection of surface defects with the effective ABIS II high-precision surface inspection system opens up new perspectives in quality assurance.

Perfect surfaces and documented automotive body shell quality
Gestamp Polska and VW Nutzfahrzeuge use ABIS IIfor quality control
For the first time, an automotive supplier of car body shells is using ABIS II technology for quality control and documentation. Based on the close supplier-customer relationship between Gestamp Polska (press shop Wrzesnia/Poland) and VW Nutzfahrzeuge/Commercial Vehicles (Poznan/Poland), the responsible quality managers of both companies had investigated the technical possibilities for optical surface inspection. As a result, Gestamp and VW Nutzfahrzeuge decided to purchase an ABIS II offline system for on-site operation in the press shop of Gestamp Polska. read more ..
