Plastics Granulation
From basic plastic materials to raw materials for end products
The intermediate products produced in this fashion are directly processed into the end product or are modified in additional processing steps to produce even more specialised plastic materials.
How is a special raw material made from the basic plastic materials?
MULTICOR® feeding systems are used to feed basic plastic powders such as PE and PP plus additives directly into the extruder or via a continuous mixer, by means of MechaTron® Loss-in-Weight Feeders.
Additives are fed with MechaTron® or MULTIGRAV® Loss-in-Weight Feeders with specially adjusted weigher configurations for feeding free-flowing to extremely poorly flowing additives.
The powder is plasticised in the extruder under high pressure and at a high temperature, and then modified in a physical mixing process. The granulator at the extruder discharge cuts the plastic strand into granular form.
Free-flowing products can be directly added via slide valves or butterfly valves. Poorly flowing additives can be added to the mixture by means of filling devices such as filling screws, vibratory trays or agitators. The special MULTIGRAV® L liquid feeder is available for liquids.| Etc | Products |
