New Managing Director for Galvatek

Jarno Virtanen appointed new Managing Director of Galvatek

On March 1st 2020, Jarno VIRTANEN has officially been nominated Managing Director of Galvatek, thus replacing his predecessor Ulf PRÅHL in this position.

Over the course of the past 16 years, Jarno occupied various management functions within the company including that of the General Manager Aviation since March 2011. He now steps up to the Managing Director position of Galvatek. Located in Lahti, Finland, Galvatek has joined the John Cockerill Group in February 2019 and is one of the 3 entities of the Surface Treatment Division that has been created at the end of 2018.

Next to the standard duties and responsibilities of a Managing Director, Jarno is to help build and grow synergies among the different actors of the Surface Treatment Division, while relying on the Division’s global strategy. A strategy that is foreseeing a considerable and profitable growth in the years to come, and that he will have to support with the adequate resources, both in terms of quality and quantity. In parallel, assisted by his teams in Finland and Poland, Jarno will have to reinforce client and market orientation by adapting and expanding the company’s current product offering.

Ulf PRÅHL, who has been nominated Senior Advisor with immediate effect, will support Jarno in his new responsibilities and will lend him his support in order to ensure a fast and efficient integration of Galvatek into the John Cockerill Group.

Galvatek’s owner changes name from CMI Group to John Cockerill

Galvatek is now owned by Belgian company John Cockerill, formerly known as CMI Group. Galvatek was acquired by CMI Group/John Cockerill in February 2019. John Cockerill is an established engineering company with global activities in five continents, some 6000 employees and annual turnover of approximately €1.2 billion. Despite the owner’s name change, our customers can continue to identify and find us by the Galvatek name.

John Cockerill’s global industrial customer base and long experience in the project business in different environments and cultures are valuable assets for Galvatek too. Galvatek has been a part of bigger companies also in the past, but this time our owner is an internationally recognised and experienced industrial equipment and service provider with a lot to offer in terms of our future development and growth.

Galvatek’s business consists mainly of surface treatment plants for the aviation industry, where customer references, trust and financial strength are essential. John Cockerill therefore opens up new possibilities in this sector and strengthens our position in the global markets.

John Cockerill has introduced a strategy to develop the surface treatment industry globally and especially within the growing aviation industry. This is well in line with the efforts that Galvatek has made earlier on a smaller scale. John Cockerill now has three business units working towards this common strategy: Sleti in France, Tempro in China and Galvatek in Finland.

Joining forces with John Cockerill enables us to improve our service network for existing Galvatek customers, as well as to reach new customers in emerging markets. Galvatek welcomes the new ownership and company name and is excited to start working with our sister companies under the John Cockerill umbrella.

Best regards,
Ulf Pråhl

BCW Manufacturing Group invested in an automated anodising line


BCW Treatments Ltd on Innovation Drive in Burnley is an aluminium anodising facility opened in early 2015 to provide a full service to companies using the subcontract machining services of BCW Manufacturing Group’s machine shops on the same industrial estate. Anodising is carried out in a Galvatek automated finishing line supplied by Turbex, which was deemed to be the best all-round package of three alternatives considered. Currently, an average of 2,600 square metres of product per week are finished across more than 240 part lines.

The Galvatek automated anodising line at BCW Treatments, Burnley.

Anodizing of automotive aluminium castings, sheets and extrusions

One of BCW’s automotive contracts involves the production of aluminium components mainly from A365 castings, 6060 extrusion, superplastic 5083, and 5754 sheet for a premium automotive customer in the UK specialising in manufacturing luxury sports cars and grand tourers. More recently, the subcontractor has received further business from another prestigious UK automotive customer that produces high performance 4×4’s and special operations vehicles. The work will start at the end of 2018 and entail the installation in an adjacent factory of a line for passivating components as a corrosion resistant pretreatment. Enquiries have also been received for finishing lightweight components for aircraft, such as cabin seating, and for electric cars, hybrids, amphibious vehicles and lorries. Consequently, by the end of the decade, the firm is destined to become a major force in component finishing in the north of England.

Dr Andrew Wilson, managing director of BCW Treatments explained, “Although more than a century old, modern anodising is an exacting discipline requiring extremely close control to achieve the highest quality and even more importantly the correct film properties.”Some manufacturers’ car parts are adhesively joined rather than welded and a nominal thickness of the anodic layer of between two and 10 microns is required, above which there is a risk of components pulling apart under stress. A tolerance band of four to six microns is achieved in the Galvatek line, so precise is the process.”

Two overhead transporters dip flight bars carrying aluminium components into 15 tanks sequentially. Up to five jobs can be processed simultaneously in the line.

Automation and ventilation play an important role

An enterprise resource planning (ERP) system drives the finishing process in Burnley, raising each manufacturing order and triggering the issue of material. The line’s control system learns which aluminium products are mounted on which universal or part-specific jig by scanning the manufacturing order. Once it knows the part number, the correct program is automatically selected. There are four load/unload stations at one end of the line, where components are loaded onto flight bars that progress to a buffer station from where they are picked up by one of two overhead transporters and dipped into 15 tanks sequentially. Up to five jobs can be processed simultaneously in the line.

Automatic dosing stations are provided for metered dosing of chemicals into several of the tanks, the quantity being worked out automatically according to the amount of surface area to be anodised on each flight bar. The working environment is clean and fume-free, as each tank is hermetically sealed and the lid is not opened until a transporter is directly above it. Positive pressure pulls the fumes through the handling system and extracts them to a scrubbing unit. After processing, flight bars are returned to four load/unload stations adjacent to the loading area and the test pieces are taken away for analysis, which includes pull and shear tests after adhesive has been applied. Following each successful test, the ERP system is advised that the components are ready to deliver to the customer.

The anodising line sequence

As a conveyor is not involved in transporting flight bars around the system, the anodising process starts in the centre of the line and progresses initially away from the load/unload stations. Alkaline degrease takes up to one hour in the first tank for the most soiled castings and the solution is rinsed off in town water in the next two tanks, the water being recycled between the second and third stage.

A fight bar being lowered by one of the transporters into a tank.

Tank 4 is a chemical etch using sodium hydroxide to remove pre-existing aluminium oxide from the surface of components. Immersion time is controlled to avoid unduly changing of the geometry of the components. It also precludes the need to plug holes, resulting in a cost saving and eliminating the risk of parts being returned by the customer if plugs are inadvertently left in at the time of delivery. An eco-rinse cycle in town water is performed in the next three tanks, again with recycling between the stages. The following process, which takes place at the far end of the line in tank 8, is the removal in a mix of nitric acid and hydrofluoric acid of alloying elements on the surface of components, especially of castings, that remain after chemical etching. Two further eco-rinse immersions in tanks 9 and 10 brings the pre-treatment to a close, by which time the components have travelled back past the centre tank towards the load/unload stations.

The actual anodising stage of the process is in tank 11, which contains sulphuric acid, and lasts between eight and 10 minutes, during which time a nominal 4 to 6 microns film thickness is deposited. An ecological feature of the equipment is continuous dosing of the acid, instead of recycling the fluid when the aluminium content reaches say 20 grams per litre. Avoidance of waste is made possible by employing a pump to recirculate the fluid through a retardation unit, where the aluminium is filtered out. A clean rinse in three successive tanks containing deionised water, which is produced locally within the line, ends with an ultra-clean rinse to ensure that conductivity is less than 200 microsiemens.

The last stage, prior to the flight bar being taken back to the unload station, is hydrothermal sealing at 96°C in a proprietary chemical blend. Reserved for high-end applications and involving 30-micron particulate filtration, the process seals microscopically small pores created on the surface of components as a result of dielectric breakdown during anodising.

Harri Salo is your new spare parts contact

Harri Salo has been appointed After Sales Engineer at Galvatek. In this position he serves as the primary contact for customers looking for spare parts for their surface treatment plants.

“I have been studying and working in spare part operations for decades, but this job has the broadest description so far. It feels good to have total responsibility for the entire spare parts process, from purchasing to delivery,” says Harri Salo.

Salo previously worked in spare parts and service operations at Kempower, Finnsonic and Kemppi. Kempower supplied electrical power sources to Galvatek, while Finnsonic fabricates ultrasonic washing lines and non-destructive testing devices, so Galvatek was already familiar to him. His latest job was at Kemppi Oy measuring and analysing power electronic components.

Salo graduated with a degree in Automation Engineering from Lahti University of Applied Sciences and later earned an MSc in applied electronics and electrical drives from Lappeenranta University of Technology.

He lives in Lahti with his wife and likes to spend his leisure time outdoors hiking, boating, motorcycling and staying at his summer cottage in the countryside.

Galvatek warmly welcomes Harri to our team!

N3 has overhauled over 800 engines

Automated chemical cleaning line in action at N3 in Arnstadt, Germany.

10 years of operational experience and 20 years more life expectancy

N3 Engine Overhaul Services in Arnstadt, Germany, overhauls and repairs Rolls-Royce aircraft engines and their components. A joint venture of Lufthansa Technik AG and Rolls-Royce plc, N3 has been operating since 2007 and is one of the most modern maintenance operations in the world. N3 currently serves over 40 international airlines who appreciate the company’s quality, dependability and process orientation. Likewise, N3 relies on an automated cleaning line supplied by Galvatek to handle up to 250 engines per year.

N3 offers maintenance and repair services for Rolls-Royce engine types Trent 500 (Airbus A340), Trent 700 (Airbus A330), Trent 900 (Airbus A380) and Trent XWB (Airbus A350). For individual engine components, N3 also offers repair services for the Trent 800, Trent 1000 and RB211-535 series.

For the cleaning and subsequent conservation of various components and materials, N3 Engine Overhaul Services utilizes a wide range of advanced technological processes. The entrepiece of the chemical cleaning process is the cleaning facility, where component baskets are fed, computer-controlled, via a crane system into one of 27 cleaning tanks. Each tank has a capacity of over ten cubic meters and allows the processing of components with a diameter of up to 2 meters and weighing up to 500 kilograms. Depending on the application, the tanks are filled with different mediums and heated to temperatures of between 55 and 90 °C.

Three of the tanks have been additionally equipped with ultrasonic cleaning devices. Complemented by several flexible manual working stations, this enables the individually adapted cleaning of almost all components. Components susceptible to corrosion can also be vacuum packed after cleaning so they are ready for transport and storage.

N3 chemically cleans Roll-Royce Trent aircraft engines
N3 Engine Overhaul Services has been operating Galvatek chemical cleaning line successfully for over ten years.

Martin Spallek, Head of Component Repair, you have run a Galvatek chemical cleaning line for 10 years now. What kind of experiences have you had, and what kind of life expectancy you have for this facility?

“The reliable operations of our cleaning facilities are crucial for our business. After dismantling and prior to further processing, the engine components must be thoroughly cleaned and prepared for material testing and inspection. Any interruption at this point in the overhaul process causes delays in the turnaround time of the engines.

Overall, we have had positive experiences with the Galvatek chemical cleaning line. The period over the last ten years can be divided into three different phases. In the start-up phase of N3 Engine Overhaul Services, our focus was on starting up the operations of the cleaning line and on establishing fault-free working conditions. In the second phase, we maintained reliability with only a few unplanned interruptions in our daily business. In phase three, the current phase, we are focusing more on preventive maintenance to assure the availability of the cleaning line for the planned life expectancy of our facility, i.e. 20 more years.”


What is the role of the chemical cleaning line in your overall MRO process? What percentage of engine components can be run through the automated cleaning process?

“The cleaning line is N3´s single source for the automated cleaning of engine parts for the subsequent repair and NDT processes. Nearly 80 per cent of engine components pass through the automated cleaning line. A fast response from our assigned maintenance contractor helps us to keep availability at a high level in order to get all the parts cleaned in time.”


You have relatively big facilities for aero engine MRO and you also have ambitious growth plans. Is there enough capacity and reserve for your future needs?

“N3 Engine Overhaul Services initially started its operations in 2007. Today N3 serves more than 40 international airlines on behalf of Rolls-Royce. So far N3 has overhauled more than 800 engines in the Trent 500 (A340), Trent 700 (A330) and Trent 900 (A380) model ranges. With the new Trent XWB (A350 XWB) engine, output will increase from the current 100 engines per year to 150–200 engines per year in the coming years. This year it will already be 130 engines. The cleaning line is designed for a capacity of 250 engines per year, so it supports us growing our business.”


What are the benefits of the automated cleaning line compared to manual methods? How has the chemical cleaning line met your environmental and occupational safety needs?

“The benefits are obvious: With the automated cleaning line we are able to run 24/7 operations and guarantee a high output and fast processing time. The quality of the cleaning processes is sustainable high.

One of the main principles of N3 concerns the protection of the environment and the resultant obligation of supporting the well-being of our staff and the community. Environmental protection was considered when planning the company, and certification pursuant to ISO 14001 Environmental Management was established. Within the process of the continuous improvement of our operating procedures, the reduction or avoidance of negative effects on the environment plays a central role, in addition to an increase in quality and production efficiency.

The cleaning facility is equipped with a fully automated chemical water treatment system and a Candovent ventilation system in accordance with the current requirements for environmental protection. We are also able to save a lot of water with the cascaded water supply. But the main priority is on the health and safety of the workforce. Automated cleaning reduces contact between our operators and the chemicals to an absolute minimum. In addition, the chemical line prevents the release of chemical fumes and spillages.”
