During production of thermoplast materials wasted, like sprues and rejects can be reprocessed.
Grinding these plastic parts leads to the so called regrind.
Depending on the grinding process the regrind has different and irregular particle sizes from 6 mm to 8 mm.
During production of new plastic parts a variable quantity of regrind can be mixed with new material.
It has to be noted that the dust content can cause problems in production.
