Challenge

Quality assurance backed by data

Quality checking at Schlote Saar GmbH is one of the core elements in the company’s entire production section. Every workpiece undergoes thorough, fully automated testing at a number of testing stations. All relevant data are recorded and documented on RFID tags on the products, depending on the customer’s requirements. Tolerances, tightness, surface quality – everything must be right before the components are delivered to the customers.

Quality from Saarland

Schlote Saar GmbH operates a state-of-the-art fleet of machines to process gearbox housings, torque converter bell housings, diesel injector pumps, and all rotating gearbox parts. Based in Saarbrücken, the company specializes in processing workpieces made of all kinds of materials using the latest technology. Its customers include many prominent companies in the automotive sector. Its manufacturing activities focus on cast and forged products, which are processed in complex manufacturing cells and lines.

We make increasing use of automated workflows, including integrated assembly processes. This means we can guarantee top quality standards for our customers, with the right processing skills in place to achieve them.

Solution

Sturdy, compact system for process documentation

Schlote uses SIMATIC and SINUMERIK controllers for its plant automation. The company also relies on Siemens quality with regard to data capture using the RFID system and on the machine control panels. The components work very well together and enable maximum transparency – important preconditions for process improvements. To continue to satisfy increasing demands, Schlote is working closely with logFOX to digitalize its manufacturing systems, and has already put in place a solution to trace gearbox components using RFID. 

Requirements from customers in the automotive sector for documentation are constantly growing, which adds to the range of tasks involved in quality assurance.

Benno Berger, logFOX CEO

Schlote and logFOX found the solution to ensure smooth process documentation in a robust industrial tablet PC that can be used in all areas of production. “We use the SIMATIC Industrial Tablet PC to collect data directly from the components and for the rational, real-time analysis of error data at the quality control stage, which lets us reflect all the blocking and release processes, including error analysis,” says Wolf. “It was important for us to have a reliable solution we could use to record data and access the information we needed at any time, even away from our regular desks or production work stations. That means we can save a lot of handling effort and thus a lot of time, which makes our quality control processes a whole lot more efficient.”

Customer benefit

Integrated platform with potential

A good working relationship with Siemens and the industrial skills offered by Siemens were the factors that convinced Schlote to opt for the SIMATIC tablet PC. The device offers the right quality and performance, helping make the processes more efficient. Schlote is therefore already planning the next steps with the tablet PC.
