Shorter lead times and better quality tests at Scania's engine factory

In Scania’s engine factory in Södertälje, random tests are made on the engine blocks to guarantee that they are of sufficiently high quality. A manual random test has a 3 hour lead time. Elektroautomatik has helped Scania with an automatic solution where each random test now only takes 3 minutes.

 

Quality test by manual tests

In Scania’s engine factory in Södertälje, the engine blocks are quality assured in the form of random tests where an operator measures the engine block at several predetermined points. Because the work is done manually, the process is both heavy and very time consuming for the operator.

– We realised that we needed to find a solution to the problem and received inspiration from one of our factories in Brazil, says Fredrik Zelazny, responsible from Scania’s side. We had parts of the solution ourselves, but we needed to find a supplier who could help us finalize our ideas.

“Elektroautomatik helped us to finalize our idea and even came up with important additions that we hadn’t thought of ourselves. As a customer, it feels good when a supplier questions our requirements because it’s an acknowledgement that they really have thought about it.”

During the procurement of a supplier, Elektroautomatik was an unknown actor for Fredrik and his department.

– Elektroautomatik had delivered several automation solution to other parts of Scania earlier, but in our department, the company was a completely unknown supplier, Fredrik says. Naturally, we talked with internal references, but we also made a reference visit to one of their largest customers who talked very well about them. So, from several candidates, the choice fell upon Elektroautomatik.

From 3 hours to 3 minutes

The solution became an extension of the existing station, which means that the engine blocks no longer must be lifted off the line for measurement. Instead, the actual measurement can be performed using a so-called measurement arm that makes the predetermined measurements and then stores the information.

As a result, the lead time for a random test is shortened from 3 hours to 3 minutes. In addition, the measurement results are of higher quality and can be stored in a traceable way.

– The challenge of the project was not to risk the safety in the rest of the line, Fredrik says. When you add or remove something, it always involves a risk. However, everything went well and Elektroautomatik could even carry out the installation during production.
