CLEANING COMPONENTS.
TECHNICAL CLEANLINESS ACCORDING TO VDA AUTOMOTIVE STANDARDS.
Today, technical cleanliness is an important quality feature in the automotive industry, in medical technology and in the electrical industry.
We provide a specially developed cleaning process – the spray water degreasing – on plants of up to 60 meters in length. In the process, we remove particulate contamination, so-called residual dirt, and filmic contamination on metal parts.
WHAT EXACTLY IS RESIDUAL DIRT?
Technically, residual dirt refers to soluble substances or solid particles that are present on a component or part after it has completed the final production step. In this case, the residual dirt is usually introduced by components from suppliers or often arises unintentionally during the processing of parts. After carrying out assembly work, especially in a gearbox or engine for example, it is advisable to treat the parts with technical cleanliness. Inorganic, quite hard particles in particular could shorten the service life of a final product in the long term, either due to abrasion or the clogging of cooling channels, for instance.
RESIDUAL DIRT IS OMNIPRESENT IN PRODUCTION.
Common examples of residual dirt on production parts include mostly metals, minerals, organics, fats and oils, and salts. Freeing parts from such residual dirt is essential for downstream processing steps such as coating or painting, but also for assembly work that needs to comply with the tightest tolerances.
TECHNICAL CLEANLINESS AT HMT:
HOW WE CAN HELP YOU.
We define our respective process of technical cleanliness based on the degree and type of contamination of the component surface. For this purpose, we measure the number, composition and size of the dirt particles and determine the weight of the residual dirt. After that we recommend various thresholds which we can use for technical cleanliness. However, we leave it up to you to decide what is most important for your products. An inspection of technical cleanliness at HMT is carried out using state-of-the-art technology, drawing on the German Association of the Automotive Industry’s VDA Volume 19.

CLEANING TECHNOLOGY AT HMT.
Multifaceted approach to metal processing. However, the same applies to the contamination it leaves on the surfaces of parts: oils, greases, emulsions, abrasions, chips, metal flakes and more. We offer effective and cost-efficient cleaning of parts undertaken to the highest level of cleanliness. Thanks to our speedy sample production process, we can make a qualitative statement on the feasible thresholds for technical cleanliness within a very short time. Our dedicated spray cleaning process removes all contamination while parts are being cleaned.
PERMANENT CONTROLS IN THE LABORATORY.
In addition, we are experts for non-bulk goods with stringent requirements on cleanliness. This enables us to meet almost any stipulation efficiently and favourably. The results of our cleaning processes are subject to the stringent on-going controls of our in-house laboratory.

INSPECTORS FOR TECHNICAL CLEANLINESS.
THE HMT RESIDUAL DIRT LAB.
HMT has its own residual dirt laboratory. Here we draw on state-of-the-art analysis methods to assess the technical cleanliness of the most diverse parts and their components in accordance with VDA 19-1 and ISO 16232 specifications, complying with thresholds specifically applicable to the part in question, with processes validated by means of decay curves. Customers receive a detailed test report after each part has been examined.
OPTIMISING PROCESSES THROUGH COLLABORATION.
Close collaboration with customers’ respective departments enables processes to be optimised and secured. We would also be more than willing to examine your components based on current specifications.
