Nondestructive inspection solutions for the automotive industry

LINQcase and Ceit have developed a solution, funded by the Hazitek program, to improve the inspection of defects in hardening and grinding processes in automotive axles.

Non-destructive techniques, which allow the quality of parts to be evaluated in a non-aggressive way, are used to evaluate a large number of industrial processes. They are processes that do not alter the microstructure and mechanical properties of the material, such as hardening, grinding or hot or cold stamping. In other words, currently the only way to determine if a part has appropriate mechanical properties for these processes is to cut it and analyze it, rendering it unusable. These methods are costly, slow and can only be used as statistical process control, not guaranteeing adequate traceability of part quality.

LINQcase was founded with the intention of responding to this problem. The value proposition of business is to perform 100% control of parts using electromagnetic non-destructive techniques. For example, for a line producing 250,000 parts/year, LINQcase's solution would result in a reduction of the defect rate by 7%; an increase of 17,500 parts and a saving of 5 M €/year.

At framework of the Hazitek program, LINQcase and Ceit have developed a system for the inspection of automotive camshafts and, more specifically, of the hardening and grinding processes of these parts. It is a monitoring system that, by means of electromagnetic sensors, will avoid the destructive inspection of parts and the statistical control of the process, making possible a unitary traceability of the components.

The system is part of the project called LITEBURN, for the reduction of quality defects in camshafts, in which LINQcase and Ceit, member of the Basque Research&Technology Alliance (BRTA) participate, and which has been financed thanks to the Hazitek program of aid for projects of research industrial or development experimental of the Basque Government.
