WEIMA was presented to the company as a viable option for a shredder from a third-party recommendation. Although the implementation of the shredder came out of necessity, they a clear vision of what the qualities of a new machine should be. They stated that it was important that the new machine be safe, efficient, and easy to operate.

The WLK 4 single-shaft shredder has a V rotor, a hopper that is batch-fed and is generally operated during one shift at an output rate of ~350kg per hour (with the ability to have a much higher throughput given a more consistent feed). The company will be able to maximize the shredder's cutting power by rotating the rotor knives regularly.

From Plastic to Plastic

The actual materials that are processed and shredded are: polypropylenes, polystyrene, and polyethylene – prominent materials in plastic. Roughly 250,000 kg of these materials are processed each day and most if it comes from within the plant. Only a few raw materials are outsourced. The extra material that comes from imperfect products is recovered, shredded, granulated, and then reintroduced to make a new product that will sell.

The installation of the WEIMA shredder minimized waste and maximized, space and revenue simultaneously.

Shredded plastic material can be seen in different stages: Shredded, granulated and repurposed into new hangers.
