Preh GmbH – Reliability guarantees high quality

The Challenge

Preh GmbH is a supplier to the automotive industry and manufactures vehicle control systems. With Preh GmbH demanding the highest quality standards, their visual inspection stations have a special relevance and make use of a PrehKeyTec solution to help them in this pursuit. These inspection stations are used to test control panels, paintwork, injection-molded parts and other internal items, defective parts are identified and rejected. Particularly important during the inspection process is that the results are recorded easily and reliably. The recorded results are then analyzed to improve the processes and also help improve the quality.

The Solution

By using a PrehKeyTec MCI 30 pre-programmed keyboard, which provides flexible key assignment, programming and labelling, the perfect keypad for visual inspection at Preh GmbH was developed. The keypad is directly connected to the PIRAT [Pre(h)mium Inspection Recording Analysis Tool] software. The whole system and process is designed to be extremely user friendly and easy to use, which minimizes input errors. Integration into the system eliminates the need for manual data entry by hand into tally sheets or any spread sheet applications. Preh can therefore rely on the numbers from the PIRAT system and adapt the processes as needed. This allows Preh to guarantee and maintain a high quality inspection process.



"The MCI 30 keyboard from PrehKeyTec helps us to perform the inspections of our products more efficiently and reliably."
