Frequently asked questions

Short and factual: the key questions about industrial parts cleaning — from process selection to the free trial.

Common questions about industrial parts cleaning. Your question not covered? Get in touch — technology-neutral, no-obligation advice.

Which cleaning process suits my application?

It depends on the part, the contamination, the material and the batch size. TeSe advises on a technology-neutral basis and recommends the right process from its entire portfolio — not its own product. The basis is always a trial on your original parts.

Aqueous cleaning or solvent — which is better?

It depends on the contamination. Following the principle of “like dissolves like”, solvents remove non-polar contamination such as oils and greases, while aqueous media handle polar contamination, salts and particles. Often the trial decides.

Can I test a process beforehand?

Yes. At our site in Nürensdorf we test your original parts: 1–2 hours of testing free of charge. In-depth feasibility studies cost CHF 1’200 per day and are 50% credited against a machine purchase.

What do technical cleanliness and residual contamination mean?

Technical cleanliness describes the permissible residual contamination on a part — for example particles or filmic residues. It is assessed gravimetrically (residual contamination weight) and by particle analysis (size and number of particles), among other methods; in industry, standards such as VDA 19 and ISO 16232 govern this. We assess the cleanliness of your parts in trials and through surface analyses.

How does working with TeSe unfold?

From clarifying the task to trial and process selection, through to commissioning and support. The “How we work” page describes the five-step process.

Which industries does TeSe serve?

Among others automotive, medical technology, precision and watchmaking industries as well as electronics and other manufacturing sectors. The right process depends on the part and the cleanliness requirement.
