Requirements in automotive
In the automotive sector, component cleanliness is an integral part of quality requirements along the supply chain. Oils, greases, chips and filmic residues have to be removed process-reliably — often inline and in series.
In the automotive industry, the benchmark for component cleanliness is VDA 19 (closely linked to ISO 16232): the rule set of the German Automotive Industry Association (VDA) covers both particulate and filmic contamination and defines the corresponding measurement and analysis methods. This defined, verifiable cleanliness is exactly what our cleaning processes target.
Suitable processes
Which process fits best depends on the part, the contamination and the batch size — we advise on a technology-neutral basis. For this industry, the following are particularly relevant:
- Wet-chemical cleaning — aqueous or solvent-based cleaning, also for oils and greases
- High-pressure cleaning — cleaning and deburring with the high-pressure water jet
- Laser cleaning — selective, contactless removal of defined contamination
- Plasma & corona pre-treatment — cleaning and surface activation before bonding or coating
- CO₂ snow blasting — dry, residue-free cleaning in step with the cycle
