High-frequency presses
Presses for high-performance production
In applications with high quantities, high-frequency presses stand out for their short pressing times. Production is accelerated greatly by high-frequency glue application. HF presses are also necessary if parts exceed a certain thickness. If parts over 30 mm thick need to be pressed, the components cannot be heated through by commonly used heating systems. Heating such parts would take too long. A heating time of one minute is assumed for each millimeter of material thickness in common molded parts, in addition to the base time which varies by glue. During pressing, the glued joint is heated from both sides. This means that, for instance, if you wanted to press a product that was 12 mm thick, you would assume a pressing time of six minutes per workpiece, in addition to the base time. Above a certain material thickness, the times can become unfeasible. In addition, heating times depending on component thickness are not linear. Instead, the heating time curve flattens out.
Systems using a high-frequency generator are the solution. The glue is brought up to the required high temperature quickly. The pressed or molded part only needs to be under pressure for a short time (compensation time) for moisture to be removed from the part. With wooden molded parts, the time must be adjusted so that the wood retains its desired shape and is not affected by shocks due to steam. Otherwise, the workpiece could tear.

High-frequency presses from Joos
High-frequency presses from Joos are in operation in many different industries. They are used to manufacture a wide range of products, such as panels, fins, molded parts for the packaging industry or the construction sector. They can be operated as multi-daylight presses. We recommend systems in which one high-frequency generator is installed for two presses, to fully utilize the generator’s capacity. While the parts are heated up and pressed in one press, the other press can be emptied and fed. This ensures efficient use of the generator.
As a press specialist, we are glad to adapt our high-frequency presses to customer requirements. Please get in touch with us!
