Wemhöner short-cicle press-line for MFC panel & floring at Krono Swiss, Menznau/Switzerland
WEMHÖNER OPEN HOUSE, ON FRIDAY 13 JULY 2018 IN HERFORD / GERMANY
If you produce panels, furniture, kitchen-doors with membrane presses or laminate-flooring, you have to go at Wemhöner’s Open House, where you will learn about the latest technology innovations.
Datalignum recommends it!

21 September 2015 Products with the label "Swiss made" enjoy an excellent reputation. That's why Kronospan has used Wemhöner technology to produce panels for furniture and flooring. First of all, however, we would like to introduce Wemhöner. Today Wemhöner – a family-run business for 90 years – produces machinery and equipment mainly for value added wood based panel processing worldwide, and employees over 410 people.
In its core business, the design and delivery of short-cycle press lines for melamine film lamination, Wemhöner has strengthened its market position. It is now a worldwide leader in the industry thanks to the high level of performance, quality and affordability of its excellent technology, applied down to the last detail. Outside of the European markets (where it is already strong) like here in Turkey, Wemhöner could grow further, especially by reaching out to South America and Asia. Wemhöner exceeded its revenue goals in 2013, by crossing the €100 million line for the first time in its history. High quality and cost-effective technology Swiss Krono Group headquarters are located in Menznau, in the Canton of Lucerne (Switzerland). Here, the company manufactures particle boards, HDF, MDF, post-forming elements, laminate panels for furniture and flooring, employing around 400 people under the Kronoswiss brand. Simple film composition, top and bottom This specific application requires that the intermediate paper magazine be designed to feed the three layup stations without causing downtimes during the process. One of the layup stations is equipped with three apertures; the other two stations have two. These elements have a direct impact on the functioning of the production line to ensure that the film structure can be programmed quickly and easily, especially at the top and bottom edge, and to make it easier to change the elements involved. This ensures, right from the production phase, that the film composition, top and bottom, can be programmed quickly and easily and changes easily performed. The lay-up accuracy of the decor papers for embossed-in-register printing is +/-1.0 mm. The correct position of the decorative films is checked and aligned with a special camera and alignment system before infeed into the short cycle press. The system records the tolerances (in length and width) resulting from the printing process and impregnation of decorative films and automatically transmits them to the press. The raw boards are fed into the production line from their magazine, with six infeed and two residual board positions, via gantries with vacuum suction cups, after passing the brush cleaning station. Work pieces can range from 2,500 to 3,250 mm in length, with a maximum width of 2,070 mm and a minimum thickness of 4 mm. The maximum thickness depends on the substrate: Particleboard 50 mm, MDF 40 mm and HDF 20 mm. Heating technology that makes the difference. Surface defects may occur if the press plates are not exactly straight; this happens any time there are temperature differences among the different press plates. These temperature differences may lead to a curvature of the surfaces concerned, even if only a few millimetres. This can be seen even with a heated plate measuring 3,450 x 2,200 mm, as in this case. Wemhöner has tackled this problem using smart heating technology that ensures the right temperature from the first to the last plate. The smart technology ensures that temperature losses occurring when heat is transferred to the substrate are compensated within seconds. This top-level technology is able to handle 240 press cycles per hour in standard mode, or 180 press cycles per hour in synchronous mode.
