Cetim Engineering

Your expectations

You manufacture products and components for which cleanliness is an important criterion.

As a player in sectors such as mobility (aerospace, automotive), energy, health (medical), space, defence, etc., you need to guarantee a certain level of cleanliness for your products in order to meet customer specifications and comply with the increasingly stringent current standards (ISO 16232, VDA 19).

More particularly, the development of hydrogen (H2) and the electrification of transport involve new issues in terms of components cleanliness.

In this context, you are looking in particular to:

Understand the requirements and specifications of your customers in terms of cleanliness
Measure the level of cleanliness of your parts (particulate and chemical cleanliness)
Control the cleanliness of your production site (sources of contamination and pollution, etc.)
Develop your staff’s skills
Acquire or develop appropriate cleaning processes

Our solutions

Our Cetim experts assist you throughout your project to control the quality and reliability of your products and secure your investments:

Measurement of the particulate cleanliness of your parts, in accordance with customers' specifications. Our testing resources allow us to analyse all types of parts, from micro-engineering to tubes and including components weighing up to 100 kg and 1 m in size.

Audit of your processes
Setting up an optimal, cost-effective organisation for the “Cleanliness” function within your company:
- Determination of the best processes and practices
- Definition of working environments adapted to your context
- Cleanliness measurement equipment selection
- Cleaning equipment selection
- Implementation of a “Cleanliness” culture (training, change management, etc.) Cetim Academy® training courses

ZOOM ON HYDROGEN

HyMEET, our technological platform dedicated to H2, provides mechanical engineering with resources and skills needed to master low-carbon hydrogen production, distribution, storage and utilization technologies. HyMEET combines an ambitious R&D program with a €25 million investment in resources dedicated to characterization and validation tests (up to 1000 bar and in a range of temperatures from deep cryogenics to high temperatures) as well as consulting and training.

Its activities are dedicated to:

Characterizing the behavior of materials in contact with hydrogen
Development of specific test methods
Characterization of specific mechanical equipment and systems in severe hydrogen environments.

Our equipment enables:

Mechanical characterization of materials using fatigue machines in a high-pressure hydrogen environment
Control of sealing systems and plant containment, with test benches developed to study gas diffusion phenomena, resistance to rapid decompression and sealing performance under severe conditions
The study of the ageing of test specimens in high-pressure autoclaves
Tests under cryogenic conditions for the use of hydrogen in liquid form, with several cryostats fed by a helium-hydrogen liquefier
Multiphysics tests with pressure, temperature and .... cycling.
Manufacture of thermoplastic composite parts (tanks, tubes) by in-situ deposition and consolidation (in real time, with no further steps required) using our HySPIDE TP robotized cell.

Our specific services dedicated to control the parts cleanliness :

Support and assistance in controlling the cleanliness function for the H2 sector
Choice of measurement equipment and analysis of particulate cleanliness
Selection and definition of cleaning protocols adapted to the H2 sector

Your benefits

Our laboratory is accredited by COFRAC (COFRAC accreditation No. 1-7263 – Scope available at www.cofrac.fr) for particulate cleanliness measurement.

Our pragmatism and independence guarantee you a tailored answer that will meet your specific requirements.

With our 20 years of multisector expertise and our cutting-edge equipment, we provide you with assistance regarding all your cleanliness-related issues.

We are the 1^st laboratory in France equiped with an analysis bench for large parts (up to 100 kg and 1 m).

Our experts are members of standardisation committees and thus allow you to anticipate future changes

Case studies

Aeronautical industry

Airbus Helicopters

Bearings and drive systems are amongst the key components of a helicopter. Airbus Helicopters has made efforts to reduce the particulate pollution of a number of its parts during the production stage in order to enhance the reliability of these components.

Aeronautical industry

Eaton S.A.S

Further to an audit of the manufacturing process of its seals and suitable training of its employees, Eaton S.A.S. was able to achieve the high level of cleanliness recently required by its customer in just two months.

S.T.Dupont

The S.T. Dupont company was obliged to bring its degreasing activities into compliance with regulations, Cetim therefore proposed a set of solutions which will allow it to reduce its VOC emissions by 90%.

Mechanical components Energy Equipments

Danfoss Commercial Compressors

Danfoss Commercial Compressors optimised it parts cleanliness measurement activity. This industrial company gains a more efficient tool to guarantee the quality of its parts washing process and of its whole production.

Automotive

Flexitech Europe

The major instructing parties in the automobile sector require that their subcontractors implement measures making it possible to assess particle contamination of parts delivered to their customers. Flexitech Europe called on the experts from Cetim's Quality, Safety and Environment division in order to provide a rapid response to this request.

Transport Aeronautical industry Mechanical components Energy Equipments

DFD-Dense Fluid Degreasing

DFD-Dense Fluid Degreasing manufactures innovative cleaning and degreasing machines for mechanical parts. With these machines, jointly developed with Cetim, the company makes the most of the specific properties of supercritical carbon dioxide (CO₂) in a cost-efficient manner for industrial manufacturers.
