The AutoInspect consortium, a European Framework 7 (FP7) funded project, has developed a digital radiographic system for the real time inspection of Metal Injection Moulded (MIM) and Powder Metallurgy (PM) parts, both in the sintered and green state. This technique has been developed in order to detect small cracks, flaws and density variations in-line in parts produced in a factory environment.
The AutoInspect system is able to inspect MIM and PM parts in seconds. Embedded Time Delay Integration (TDI) linear X-ray detectors allow the supply conveyor to run continuously while a row of parts is simultaneously scanned.
The TDI technique creates very low noise X-ray images with resolution up to 10 μm pixel size, depending on X-ray set-up magnification. A dedicated image analysis algorithm for the automatic detection of defects with pre/post processing and an enhancement algorithm is used to determine good and bad components.
TWI Ltd, a consortium partner based in Wales, UK, hosted a prototype demonstration on December 12th at the company’s premises in Port Talbot.
Partners in the AutoInspect project are:
- Accent Pro 2000 s.r.l
- MIMTech ALFA SL
- Polkom Badania
- TWI Ltd
- Brunel Innovation Centre
- Vienna University of Technology
