New technology cleans parts with dry CO2 granules

For in-line dry component cleaning applications, ACP systems is releasing itsPowerSnow QuattroClean technology. The process compresses recycled liquid CO2 into cleaning granules using an integral unit. Compressed air then accelerates the granules, fed through a purpose-designed nozzle, for blasting on to surface that requires cleaning. Thanks to the elimination of the customary external pellet production and logistical effort associated with conventional dry ice cleaning, it is possible to realise a fully-automated and uninterrupted cleaning or deburring process.

The new cleaning process efficiently removes stubborn particulate and filmic contamination from virtually all materials and material combinations. Using cleaning granules made from recycled liquid CO2, the process can clean entire surfaces or selected areas in a reproducible manner. Applications range from surface finishing in body-in-white automotive processes and the removal of welding beads, to the fine deburring of medical instruments and fine-tolerance watch components.

Cylinders or tanks feed the mediato the QuattroClean PowerSnow system, thus offering unlimited shelf life.The jet of compressed air containing the granules has a temperature of around -78°C.

On impacting on the surface, four effects occur. A thermal effect leads to sudden local cooling, where the different expansion coefficients between the substrate and the contaminants cause cracks to form in the latter. A mechanical effect also takes place, where the transfer of momentum detaches impurities. When the snow granules impact on the surface, they undergo a transition from the solid to the gaseous phase, with an abrupt increase in volume of around 600 times. This so-called sublimation effect creates micro-pressure waves that also detach contaminants. In addition, during the transition phase, a solvent effect removes filmic/organic contamination.

MEETING CURRENT AND FUTURE COMPONENT CLEANING REQUIREMENTS THROUGH DIVERSIFICATION INTO HYDROGEN TECHNOLOGY

The economy is undergoing a transformation that poses challenges for many areas of industry. New products and various megatrends require adjustments to manufacturing technologies, as well as to the range of products and services available. Ecoclean GmbH is proactively addressing this change through greater diversification of its solution portfolio for industrial component cleaning and by introducing the new business area of hydrogen technology.

Energy transition, sustainability, demographic change, mobility, automation and digitalisation, and security: these megatrends are resulting in technological and social changes. And at an increasingly rapid pace. This development demands increasingly higher flexibility and agility from companies, particularly in the field of industrial parts cleaning. Whereas yesterday it felt like the automotive industry was setting the standards in terms of cleanliness requirements, today it is completely different industrial sectors, each with its own specific requirements.

Ecoclean, a global specialist in the supply of equipment and systems for industrial component cleaning, surface treatment and automation, is responding to these changes with a future- and market-oriented diversification strategy. The course for this approach was set several years ago with corresponding financial and personnel investments. As a result, new solutions for high-tech industries are now available, in addition toequipment and systems for tasks in the previous sectors, such as automotive and its associated supply chain, mechanical engineering, joining technology, the jewellery and watchmaking industry, and the aerospace arena.

Also included in this ensemble is the semiconductor industry and its suppliers.To be able to manufacture ever smaller and more powerful microchips by means of EUV lithography, means placing extremely high demands on the components required for the production equipment in terms of purity. In addition to ultra-fine particulate residual impurities in the nanometre range and extremely strict specifications regarding filmic contamination, outgassing rates for organic substances and residual moisture as well as ‘prohibited’ substances/elements play a quality-critical role. Likewise, it is necessary to meet stringent cleanliness requirements for vacuum technology components in the UHV, XHV and UCV range –such as those required in high-power laser systems, high-tech measuring instruments and analysis equipment, for example.

Precision optics, micro-optical parts and sensor systems, among others for semi-automated and autonomous driving as well as industrial digitalisation applications, also require avery high degree of cleanliness for lasting fault-free function. For these challenging tasks, Ecoclean offers industry and application-specific solutions from pre-cleaning to intermediate and final cleaning connected to or integrated in a cleanroom. For the design of process and plant technology, the company has its own High Purity Test Centre with a validated clean room and corresponding measurement technology.

High cleanliness requirements have always been commonplace in medical technology. With the introduction of the European Medical Device Regulation (MDR), the requirements for cleaning medical devices such as implants, instruments and equipment, as well as for qualification, documentation and traceability of the processes, have become even stricter. In the meantime, the US Food & Drug Administration (FDA) is planning to harmonise its quality system regulation with the MDR, so that uniform regulations will apply regardless of market access.

To solve the very different tasks in medical technology in a requirement-oriented, efficient and sustainable manner, Ecoclean offers a complete and globally available portfolio of qualified cleaning systems. Co-operation with renowned partners also enables the realisation of turnkey projects with corresponding packaging and cleanroom solutions.

Software specially developed for medical technology, RFID technology and audit trails ensure the complete fulfilment of all specifications regarding component identification, documentation and traceability. In addition, the company’s experts provide support with qualification (IQ, QQ and PQ) on request. Thanks to the Ecoclean’s comprehensive medical technology and regulatory know-how, combined with extensively equipped technology centres (including a cleanliness laboratory and validated cleanroom), it becomes possible to devise the technically and economically optimal solution for every cleaning task. The potential duplication of this solution for further production sites is straightforward, a process that subsequently accelerates qualification and commissioning.

By entering into the development, manufacture and sale of electrolysers for the production of green hydrogen and solutions for its use, the company is opening up a new business area. To this end, Ecoclean and the Zentrum für Sonnenenergie und Wassersoff-Forschung Baden-Württemberg (ZSW) are pooling their expertise in the joint ‘EcoLyzer BW’ project. Based on robust and well-tested system technology for alkaline pressure electrolysis developed by the ZSW and Ecoclean’s expertise and decades of qualification in process engineering and industrial production technology, electrolysers are designed as modular systems with compact standard modules.

With power classes initially ranging from 1-10 MW, they enable the simple and cost-efficient construction of electrolysers adaptable to a wide range of applications. Typical uses include those for industry, mobility, energy supply for neighbourhoods and storage of re-generatively produced surplus energy from wind power and photovoltaic plants.

A first solution in this area came to fruition in September 2023 with a test rig for alkaline pressure electrolysis. It will make it possible to test and validate electrolysis stacks with an output of up to 500 kW and a diameter of 1200 mm.Through this diversification strategy, Ecoclean is helping to meet the challenges associated with disruptive developments, as well as various megatrends.

First-rate contacts, new projects and concrete deals

Technical discussions, a strongly attended expert forum and a positive overall mood on all three days of the trade fair testified to the fact that the recently concluded 20th parts2clean exhibition fulfilled all expectations. More than 3000 trade visitors came to the event, the majority of them armed with tasks and projects, as well as a thirst for new information. This resulted in numerous high-quality contacts, new projects and even direct business deals for the more than 150 exhibitors (from 14 countries) at the event.

“We placed a stronger focus on the range of solutions offered at parts2clean for tasks where the highest cleanliness requirements need to be met,” reportedChristoph Nowak, project director at Deutsche Messe, “We thus succeeded in attracting more visitors from this segment of the industry to parts2clean.”

This was confirmed by Dr Günther Schmauz, board member at ACP systems: “With our high-purity snow-blast cleaning solutions, we were previously more of a niche supplier at parts2clean. At this year’s event, however, we were able to welcome a large number of trade fair guests from the fields of EUV lithography, including system partners and suppliers, as well as e-mobility.”

Rainer Straub, board of management and VPsales andcustomer service at
Ecoclean, expressed similar sentiments: “Parts2clean was significantly more successful for us this year than in 2022, certainly due to the ‘high-purity’ theme, which is a focal point in our programme.”

According to Manfred Holzleg, general manager of Safechem Europe “parts2clean always provides the opportunity to meet a diverse audience. This year, we were able to hold numerous discussions, especially with visitors from industries that are new to us. As a result, we can open up new fields of business.”

Eight times faster shot blasting at ML Constructie

The lack of flexibility and unsatisfactory powder coating qualities at external job shops induced a Dutch manufacturer of industrial furniture to bring its coating operation in-house. Unlike its competitors, ML Constructie decided to also perform paint preparation by shot blasting in-house with an automatic shot blasting machine from Rösler. Compared with manual processes, the shot blasting cycle times are not only eight times faster, the
automatic solution also produces better qualities at lower costs.

Since manual blast operations are hard and exhausting, it is very difficult to find and keep the people for this kind of work. With the Rösler blast machine, however, employees must only place workpieces onto the respective fixtures and remove them after the blast process.

Another significant contribution towards a better working environment is the low noise emissions, which are considerably lower than manual blast rooms. Moreover, the automated shot-blast process is eight to 10 times faster, while another benefit is the blast machine’s two rails in ‘Y’ design. This configuration allows the operator to place workpieces onto the fixture at one rail branch, while workpieces from the other rail branch undergo blasting. Therefore, unproductive idle equipment times aremore or less a thing of the past. Last but not least, the overall blast cleaning quality is considerably better.

“In the automated shot-blast process, blast media gets into even the tiniest workpiece
corners,” says Ben Luizink, co-owner atML Constructie.”This is nearly impossible with manual shot-blasting operations. Furthermore, the Rösler shot-blast machine is very
tight and emits practically no dust. Since we are coating the workpieces in the same production hall, this is a huge benefit.”

IMI Truflo Marine invests in MecWash system

The addition of the MecWash MWX300aqueous cleaning system has made a dramatic impact at IMI Truflo Marine, increasing cleaning productivity by over six times while reducing the operational manpower required. IMI Truflo Marine noted a significant improvement in both efficiencies and the standard of cleaning, helping the business to meet global demand. This historic naval valve manufacturer makes flow control solutions, with over 120,000 valves in service on 24 of the world’s naval fleets.

The precision cleaning and sophisticated drying processes offered by the MWX300 ensures components produced by IMI Truflo Marine are free of contaminants, preserving the critical tolerances necessary. The company’s parts have very tight tolerances, and even small amounts of dirt or contamination can prevent them from functioning properly.

Kurtis Smith, continuous improvement engineer at IMI Truflo Marine, says: “Truflo needed a machine that could provide a consistent and high-quality finish on valves in sensitive materials used in marine systems. It was important for the business that the new system could improve productivity with less manpower required in the parts washing process.

“Since the installation in 2022, the MWX300 has delivered impressive cleaning results, especially considering its size,” he continues.“The cleaning process has always been challenging due to the sensitivity of the parts and the mirror finish required. Previously, we could only clean three valve kits in a 30-minute cycle; using the MWX300 we are cleaning 12 kits within 18 minutes, with a smooth and polished finish.”

The previous cleaning method at IMI Truflo Marine was manual and required the blow drying of parts with air guns after washing. Now, the company simply loads baskets of parts into the MWX300 and presses start.
