Valmet has been manufacturing shoe press belts for the global industry since the mid-1990s. Nowadays, Valmet Black Belts are known for their outstanding substance combine, extensive life time and good dewatering capacity. To fulfill the demands of today’s paper creation, Valmet has a short while ago designed yet another belt type: Valmet Black Belt Valmet Black Belt H is actually a superior-effectiveness belt for all shoe presses. On account of its high longevity and mechanical strength, it can be Similarly well suited for both speedy- and gradual-working paper and board equipment. “As compared to our other belts, the new H type has greater dewatering Attributes and minimized crack growth mainly because of the new elastomer formulation and versatile paper aspect reinforcement. The partly clear elastomer allows exact Charge of the casting course of action and high-quality,” clarifies Satu Hagfors, Product or service Group Manager for Belts at Valmet. Very carefully chosen Uncooked elements guarantee outstanding belts. The new reinforcement yarn was decided on just after thorough work. “The new H-sort yarn has better toughness, better flex Attributes and decrease deformation hazard than preceding reinforcement yarns, generating much better mechanical strength even beneath Serious machine disorders,” Hagfors says.
Quality by no means goes from fashion
During the last several years, Valmet has invested appreciably in the quality of the shoe push belt production system. The casting process is extremely fragile, and for that reason vulnerable to any changes from the disorders on the manufacturing facility, such as temperature and humidity. The listing of advancements built while in the casting process is considerable. “For instance, we now have knowledge logging methods including substantial-pace HD cameras to acknowledge any casting disturbances. The info loggers comply with up about a hundred parameters throughout casting. The on-line graphs are visible within the operators’ Command screens all over the course of action and they are double-checked Later on by good quality personnel. To more increase the Charge of our casting system excellent, We now have created our belts partly clear making sure fabricsystems that we might also inspect the critical yarn structure just before finalizing the belt,” Hagfors explains. Launching new items isn’t done overnight, as references are really critical inside our organization. Even immediately after we get our belts running, we may have to wait for a year for getting knowledge from your applied belt. Via screening, we are able to present the new Valmet Black Belt H retains its mechanical Attributes even beneath Intense loads the place other belts shed their power and dimensional steadiness as the reinforcement fibers get broken,” Hagfors states.
The most up-to-date investments at Valmet’s creation web site in Tampere, Finland, have amplified the level of automation within the creation system. “We now have computerized techniques to make sure exact dosage and homogenous mixing of the many polyurethane elements and procedure additives. Also, the finishing equipment is upgraded having a new automation system to make sure the surface area top quality,” Hagfors proceeds.
Inspection and Investigation Engage in vital roles in product or service growth
Valmet is Similarly considering providing great belts to its prospects and acquiring new merchandise for potential requires. For that purpose, Valmet has improved the particular manufacturing course of action, and creating other revolutionary techniques to inspect the concluded item and comply with it up all through its life cycle. “By way of example, we make use of a Distinctive scanner to observe the grooves on our belts right before shipping, throughout shutdowns, and at our laboratory once the removing from the belt. The knowledge is used for even more merchandise development,” Hagfors states. Launching new merchandise takes time A further proof of Valmet’s innovativeness will be the examination equipment produced only for belt improvement needs. “Inside of a check, samples are run for sure moments via a nip less than three distinct pressures. The temperature and length with the samples are monitored through the exam. Also, the tensile Homes in the samples are calculated as new and once the take a look at,” Hagfors describes.
The exam equipment is a true asset in new item launches.
“Launching new items isn’t done overnight, as references are really critical inside our organization. Even immediately after we get our belts running, we may have to wait for a year for getting knowledge from your applied belt. Via screening, we are able to present the new Valmet Black Belt H retains its mechanical Attributes even beneath Intense loads the place other belts shed their power and dimensional steadiness as the reinforcement fibers get broken,” Hagfors states. The new Valmet Black Belt H retains its mechanical Qualities even under Intense masses. All in for The purchasers The belt manufacturing approach is rather fragile, plus the product itself can be fantastic-tuned with different area designs. “The uniqueness with the belts highlights the importance of having committed income personnel and solution supervisors. We must know our shoppers and have our ears huge open up. I’m happy to say Now we have An excellent team and point out-of-the-artwork machines to make sure top-good quality items and repair for our buyers. This can be how we Dwell Valmet’s values: we generally go the extra mile to move shoppers’ general performance forward,” Hagfors concludes.
