Production with greater flexibility, higher speed and more efficiency – that's what the specialist door manufacturer PRÜM had in mind. And that's why the company ordered a new production line from Reichenbacher Hamuel – a production line that by its complexity and speed has set new standards even for Reichenbacher.
Innovative power, service and their clear sales strategy have made PRÜM one of the market leaders for door production in Germany. The portfolio of the company, which was founded at Weinsheim in the Eifel region in 1970, includes apart from a great variety of standard, reproduction style, lifestyle and designer doors, also high-quality purpose doors, such as noise and smoke protection doors, as well as burglar- and fire-resistant doors. A comprehensive choice of surface materials, from solid wood and veneer via easy to clean paints and decorative foils, up to heavy-duty CPL and HPL, symbolize their wide range of products in an impressive way.

Manufacturing & Technology

The core of the machining centre is a conventional CNC-milling machine, however equipped with two 5-axes heads. Thus, for example, it will be possible to drill a hole for a door viewer while lighting cut-outs are milled for the next work step. The use of two pin tables in the MC pursues the same principle.

No matter whether the work-piece reaches the MC from the press line for the initial door bodies, from the edging line or from the lacquering line, based on a bar code, the machine will recognize the type of door in question and perform the corresponding steps in a fully automatic way. Once the machining has been completed, the robot will remove the door and automatically feed it to further processing or packaging for the final customer. All this is not only done at unrivalled speed, but also with extraordinary precision. At right angles the deviation within one metre is only 0.1 millimetres. If a working step is repeated in the same axis, the deviation will even be a mere 0.05 millimetres within one metre.
