Extrusion International 1-2026

35 Extrusion International 1/2026 SURFACE TREATMENT Cleaning solutions for MDO rollers In addition to the quick roller change, Hosokawa Al- pine will also be offering an integrated web cleaning system to remove deposited particles from the surface. The film tube is cleaned using an extraction system with vacuum nozzles. This significantly reduces contamina - tion of the roller surfaces and extends the cleaning in- tervals considerably. Additionally, an ultrasonic bath will be available for the deep cleaning of vacuum rollers. With ultrasonic cleaning at a temperature of 60 °C, even heavily soiled vacuum rollers are deep-cleaned and, depending on the degree of contamination, are as clean as new after ap- prox. two to four hours. In future, Hosokawa Alpine will also be using a doctor blade to scrape off initial impurities. "The new doctor blade scrapes off dirt on the roller surface and removes excess particles. An internal study has shown that this significantly optimises the cleaning process. And that in turn leads to an increase in service life," explains Bayer.

A ccording to Anders Dueholm, Support and Spare Parts Manager at Vetaphone, the best manufactur- ing suppliers take a 360° view of their customers. It’s no longer sufficient to sell, supply and install technology, the responsibility goes further. This is especially the case with an ancillary process like surface treatment, which is often required, but less often understood. “To many people involved in package print produc- tion, the corona treater is a ‘set and forget’ element in the overall line, and modern systems are more reliable than their predecessors – but all technology requires care and maintenance, and the corona unit is often for- gotten until it causes a problem,” he explained. In a market sector where high-speed, high-tech, and high-cost technology works hard to keep pace with de- mand and at the same time show a profit, reliability and the reduction of expensive downtime are major consid- erations. And this is where a planned program of ongo- ing support makes all the difference because it builds cus- tomer confidence by ensuring consistent performance. “Our Preventative Maintenance Contracts offer pre- dictable costs for the user, including discounted parts and reliable technical support to resolve any issues. This support is provided locally in person or remotely on a 24-hour basis, and the service includes scheduled visits organized and carried out by fully trained staff,” he added. Vetaphone tailors its contracts to suit different re- quirements. For example, some users do not have their own in-house maintenance team, but some do, others are users with multiple units but are lacking in technical knowledge about corona, while some, known as ‘high- end’ users, require regular inspections to verify the operational condition of the equipment and its safety.
