For a customer in Mexico, we have constructed an interesting special DEUTROMAT DAS-1U machine for fluorescent magnetic particle testing of drive shafts and ring-shaped parts. This enables the routine testing of safety-relevant components with a high throughput, as usual in the automotive sector.

Two short parts (up to 280 mm) at the same time or one longer part (up to 600 mm) can be magnetised. Magnetisation is carried out using interchangeable mandrels, each with an internal flushing, and a flexible centre contact.

After magnetisation, the contacts are automatically released, the parts fall onto a chute specially designed for gentle handling and then slide directly into a inspection cabin at the rear of the system. After visual evaluation, the tested parts pass through a demagnetisation tunnel.

By parallelising several individual processes (magnetisation / extraction / viewing / demagnetisation), a throughput of approx. two parts every 10 s is possible. The system can also be equipped with a pneumatic mechanism for testing ring-shaped parts, which automatically pushes the part to be tested off the mandrel after the test cycle has been completed.
