Profiling and sanding line for sound-absorbing panels

Feb 23, 2021

Wood is the ideal building material for creating architectural elements with innovative mechanical, insulating and fireproof features. One example is sound-absorbing panels that need to be machined with the most up-to-date technologies and methods to successfully achieve a product of exceptional quality.

Processes like trimming and sanding, 3D finishing, profiling and grooving machining deserve particular attention. Because of this an increasing number of companies in the industry need to meet high levels of productivity, while equally guaranteeing absolute machining quality and precision.

Mission impossible? Not for SCM which, thanks to its decade of experience in designing and developing technological solutions for timber construction, has created a fully integrated line for profiling and sanding three-layer sound-absorbing panels.

An engineering project to cover its entire production cycle chosen, among other things, by a German company among Europe's leading players in this sector.

The advantages

Increased productivity, shorter set-up times, greater machining precision and a dramatic improvement in the finishing levels achieved are the advantages that make SCM's engineering solution stand out above the rest.

The line is controlled by a single supervision software, Maestro active watch, which ensures full integration of all the machining phases. This means that each minute 3 standard size panels are produced, as well as guaranteeing with greater flexibility and simplicity a surface finish that is very diverse and highly sought-after.

The process

The Automation process and flexibility mark the first stage of the trimming process lengthwise, that is done in a "celashi p30", unbeatable in the precision it offers compared to other machines in the same category. Integrated by a "mahros" system with roller conveyor, to automatically load pieces, it can achieve different-sized transversal cuts (from 3 metres to 1500 or 700 mm), always with the same precision and speed (from 3 to 5 panels per minute).

Once the trimming is completed, the pieces need to be brought to their required thickness. The trimmed panels are transported along the roller conveyor at a speed of 12 metres per minute, to an initial compact sanding line, consisting of two "dmc system" machines to calibrate the upper and lower faces of the panel. Thanks to 7 different machining heads, a third "dmc system" automatic structuring machine completes this stage of the process, carrying out various kinds of finishings on the panel, like different levels of rustication, with extremely attractive results and design.

Another connection unit transfers the calibrated, sanded panels to two "celaschi" squaring machines, one assigned to transversal profiling and the other to profiling the longitudinal sides, to achieve the required lengths and widths.

Subsequent stages involve the panels being further machined and perfected with surface grooving processing, to increase the sound-absorbing surface, and brushing for the final clean, done by another top-of-the-range "dmc system" which, thanks to the power and efficiency of its units, provides an excellent surface finishing.

Impregnation and manual unloading complete the process with exceptional quality results.
