*high throughput rate
*robust, high-quality construction
*process and control engineering and after-sales service from a single supplier

The customer

Environmental responsibility and recycling technology were among the top priorities when developing the concept and deciding on investment for the manufacture of innovative and award-winning products in the UPM ProFi family of products. Having set themselves the goal of cost leadership, UPM then picked AZO as a partner, with whom continuous optimisation of processes is possible at any point. UPM is a global business with headquarters in Finland and is made up of six business units: Biorefining (biofuels & cellulose), Energy (hydropower plants), Raflatac (label materials), Specialty Papers & Communication Papers and Plywood. UPM Biocomposites’ business is the manufacture of wood-plastic composites. These also include UPM ProFi products. The company is taking the bioindustry and the forestry industry towards a new and sustainable future that is characterised by innovation. The products are manufactured from renewable raw materials and can be recycled.

The task

UPM Biocomposites in Bruchsal, Germany has specialised in the production of wood-plastic composite products. This is where composites made from purely synthetic polymers and wood-based fibres, which occur as surplus by-products during processing and production of self-adhesive label material, are manufactured under the UPM ProFi brand. This low-maintenance, durable material can be used as decking for patios and balconies as well as for garden paths, yachting marinas and jetties.

AZO was tasked with designing reliable feeding of two mixing lines with bulk and medium components and minor quantities. In addition, the finished compounds had to be conveyed and stored in day bins. They were subsequently fed into several extruder lines from these silos. Currently 15 different basic formulations in six colours are produced on the mixing lines.

“From the outset we wanted a concept for the material flow that would not restrict us in any way. Where we are concerned, this means that we are able to transport all components on all mixing and extrusion lines.” Marc Reich, UPM Biocomposites

AZO’s solutions for handling bulk, medium and minor components: Azo flexidos®

The Azo flexidos® employed in this plant is extremely versatile. The most popular areas of application are reliable and flexible feeding of extruders and injection moulding machines with new materials, masterbatches, additives and regrind, when requirements are for high-quality products. It is suitable for lower and average rates of throughput.

Pneumatic vacuum conveyors are used to convey medium and minor components to the surge bins for the Flexidos® station.
