WEIMA shredder gives a second life to leftover in clothes hanger production

Following recommendations from partner companies, the choice of Plásticos Ojara finally fell in favor of WEIMA's WLK 4 single-shaft shredder.

Thanks to the use of the shredder, it is possible to recycle rejected products on-site and return the material to the production process. In this way, waste can be effectively avoided, the purchase of raw materials can be reduced, and previously unused residual plastic can be retrieved.

The WLK 4 single-shaft shredder has a working width of 600 mm and an electromechanical drive with WEIMA's own WAP gearbox in combination with a V-rotor and a generously dimensioned hopper in logspacer design. This prevents feed material from forming bridges.

As a rule, it is operated with a throughput of approximately 350 kilograms per hour, but a higher throughput is also possible with continuous feeding.

The rotor cutting blades can be flipped several times when worn, which drastically reduces the machine's maintenance costs. The shredder can be operated intuitively via the touchscreen display.

Plásticos Ojara uses only PP, PS and PE to produce hangers. Around 250,000 kilograms of these materials are processed every day, most of which come from the company's own production.

Waste generated in the production process (e.g. during start-up and shut-down) is shredded by the WLK 4, then granulated and returned to the manufacturing process to produce new hangers.

Around 30% of the clothes hangers are now made using regranulate. In addition to recycling in-house waste, the company also collects old clothes hangers from surrounding customers or stores.

By creating an internal recycling line with WEIMA shredding technology, Plásticos Ojara has now become even more independent of external influences.

Expensive raw material purchases are reduced to a minimum. This creates new scope for entrepreneurial activity and further opportunities to optimize production. Storage areas that were previously allocated become available again. Intralogistics expenses for waste handling are also reduced.
