Challenge accepted: Maximum cleanliness, shortest cycle times, fragile components.
We take the example of bipolar plates and ask our expert from the Ecoclean Center of Competence in Monschau, Germany, Joachim Ritter:
Why is this a special topic for industrial parts cleaning?
Bipolar plates consist of 2 layers (cathode and anode), usually made of uncoated stainless-steel alloys or coated stainless steel carriers, which are extremely thin and very sensitive. The raw material for manufacturing metal bipolar plates is usually unwound from a coil. This means that impurities of an unknown nature may already be present on the raw material. The material for the plates is formed, cut, and stamped using special oils.
In addition to filmic contamination, these processes also generate particulate contamination such as flake burrs, cutting chips, fibers and general contaminants from the air.
The requirements for cleanliness are very high, as any particle that is not removed can later cause a problem in the functional process.
In addition, such plates are manufactured at very high production speeds - the cycle time per part plays a very important role. Part cleaning solutions must be optimally integrated into this process.
How important it is to know the exact origin of the contaminants we want to remove?
To answer this question, we need to look at one of the most important steps in the production of bipolar plates: In a process known as "joining," the anode and cathode plates are placed on top of each other and typically welded together by laser. The welding process can be a source of contamination, which can adversely affect the subsequent performance of the fuel cell.
As can be seen in the picture above, one of the possible contaminants that can appear on such a bipolar plate are sootmarks.
These are usually caused by residual organic matter or oil particles on the surface that burn off during the welding process.
We at Ecoclean go back a few steps in the production cycle and take a close look at all the process steps.
We do this because it is important to know in advance what kind of contaminants are involved.
With our experience, we can advise our customers at this stage to use oils that can be removed later without leaving any residue.
Our solutions are therefore not just about parts cleaning, but also about improving production processes.
What else can we get clean with the industrial parts cleaning technology developed for bipolar plates?
With our technology, we can clean not only flat bipolar plates, but also cubic components such as electronic components or housings, i.e. various metallic materials with high cleanliness requirements and short cycle times.
This also includes components such as battery cell cups, heat sinks or battery connectors.
The cleaning of small parts, pre-punched as an endless belt, can also be cleaned in one piece.
Every particle that is not removed can cause problems later. Therefore, cleaning requirements are very high and require experience and expertise.
Let's take a look at how Ecoclean can support the manufacturing process, using the production of bipolar plates as an example:
For example, bipolar plates for automotive fuel cells are made from pressed graphite powder or stainless steel alloys.
The surfaces of these workpieces are usually contaminated with various substances and elements generated during the manufacturing process.
We have a lot of experience in this area - the following production steps involve forming and cutting the coil material. Oils and emulsions used in these processes can also contaminate the plates.
As mentioned earlier, oxides and sootmarks can also occur later when the plates are joined.
It is extremely important to clean the plates before subsequent processes such as coating, etc. We are able to guarantee the required particulate purity, degreasing and removal of contaminants.
This is the only way to ensure that a dense and perfectly coated bipolar plate is later used in the fuel cell and that the maximum power yield is achieved. We are active in final cleaning, surface preparation and treatment. Here we offer very efficient solutions.
What cleaning processes are applied?
There are several cleaning processes on the market. Each manufacturer must carefully weigh the pros and cons before making a decision.
For example, one solution on the market is CO2 blasting. However, we view this very critically because the bipolar plates are typically used in PEM (proton-exchange membrane) fuel cells to minimize CO2 emissions.
The use of CO2 blasting as a cleaning process is possible, but in our opinion contradictory when you are producing something that should be a more environmentally friendly solution.
Also, the high consumption of CO2 gas and compressed air is a cost factor that needs to be evaluated before a decision is taken. We see this process as more of a partial solution, good for selectively removing traces of smoke on a manageable scale. We do not recommend relying on it for the entire cleaning process.
Other solutions that manufacturers can use either individually or in combination.
We have obtained very good results in cleaning bipolar plates with steam, i.e. hot air processes. It is a fast process that is very effective, especially in removing stains and substances, while using very little liquid. When used correctly, this process allows the oil to evaporate without leaving any residue. The right temperature curves are crucial here.
Depending on the surface, we have also achieved good results with our hydro-cleaning process. We use nozzles that release the medium at a certain pressure and temperature.
To complement the cleaning process, we use other technologies such as ultrasonic cleaning, pressure-cycling rinsing or plasma cleaning, depending on the level of contamination and requirements.
In addition to water- or solvent-based chamber systems such as the EcoCwave or EcoCcore or one of the ultrasonic in-line immersion systems from UCM AG, we now offer the GEN-2 series EcoCbelt as a system for cleaning bipolar plates.
This is a continuous cleaning system in which all possible process variants such as spray cleaning, steam cleaning, plasma cleaning, hydro cleaning, CO2 blasting and drying can be implemented as required in the system concept.
The transport system is designed for sensitive components such as electronic components, bipolar plates, etc.
Is it possible to test component, contamination, and the production requirements in advance?
At our Center of Competence in Monschau, Germany, we are able to perform tests on originally contaminated components under very close to production conditions. Our laboratories are equipped with test methods such as surface tension, fluorescence analysis and infrared spectroscopy. Not only the cleaning processes but also the cycle times are tested in our facilities.
Medical Device Manufacturing - Cleaning, Passivation and Final Packaging Solutions for the Medical Device Industry
Fabio Cordaro takes us on a deep dive into the most relevant topics in medical device manufacturing.
Why is the cleaning of implants prior to coating a critical step in the manufacturing process?
Prior to coating, implants must be thoroughly cleaned of any contaminants such as oils, greases, machining fluid residues, or particles that can interfere with coating adhesion and lead to uneven coatings. And improving surface adhesion also plays an important role in durability. Effective cleaning helps to create a clean and uniform surface to which the coating can better adhere. This is essential for the long-term stability and functionality of the implant..
Thorough cleaning eliminates potential sources of contamination that may occur during the manufacturing process This is especially important to ensure implant sterility and prevent patient infection.
What about compliance with regulations and standards?
When it comes to "cleaning, passivation and final packaging," medical device manufacturers need to focus on the FDA (Food and Drug Administration) in America or the MDR (Medical Device Regulation) in the EU, depending on the country. Here are some of the reasons compliance is so important to the medical device industry:
- Proper parts cleaning procedures, passivation processes, and sterile packaging are critical to avoid contamination and ensure product integrity throughout its lifecycle - protecting patient health. These regulations ensure high quality standards in the manufacturing process.
- Regulations require the documentation and traceability of materials and processes used in the manufacture of medical devices. This helps manufacturers to identify problems that may occur during the manufacturing process. In other words, always know exactly what, where and when.
- Compliance with FDA and MDR regulations is often a prerequisite for market access, not only in the United States and the European Union, but also in many other countries around the world. As MedTech manufacturers go global, they must comply with these regulations and need a supplier that can help them navigate the regulatory landscape, rather than just selling equipment detached from the overall process.
Ecoclean has developed a passivation process called Pulsated Pressure Passivation (PPP) to meet the specific needs of the medical industry. How does it work and what are the benefits for MedTech manufacturers?
As far as parts cleaning is concerned, we already work with a process called PPC (Pulsated Pressure Cleaning), which consists of reducing and increasing the pressure in the process chamber filled with the cleaning medium to reach the areas to be cleaned or rinsed, taking advantage of the air contraction once the chamber is ventilated. We have used our experience in this process to offer a technology for the passivation process that we call PPP (Pulsated Pressure Passivation), which allows the surface to be treated with a protective layer regardless of the geometry of the component, since this change in pressure inside the process chamber causes the passivation to chemically flow into all the cavities and holes.
The new passivation process from SBS Ecoclean Group is a quantum leap for medical and high-end technologies.
Traditional atmospheric methods only clean and passivate the external geometry of the parts.
With the new process we are able to clean and passivate implants and instruments even in capillaries, internal geometries and blind holes.
We would be happy to invite you to our application laboratory to demonstrate this groundbreaking process.
PPC and PPP are patented, exclusive cleaning and passivation processes developed by Ecoclean!
