Thermal cleaning systems remove polymers, plastic additives and recyclates from machine parts
Compounding and plastics recycling are the central topics of the second Compounding World Expo in Cleveland, Ohio. As a specialist for thermal cleaning systems, Schwing Technologies will be exhibiting at the US trade show for plastics processing on November 3-4, 2021. At booth A523, Andrew S. Dickinson, US-expert from the German machinery manufacturer, will provide information on the special advantages of the thermal cleaning technology. Typical application for the systems is the cleaning of plastics from tooling and machine parts. In the compounding and recycling industry, these include in particular pelletizing dies as well as die plates, extruder screws, screens and filter discs. With Schwing’s environmentally friendly, energy-efficient and effective systems, all polymers, plastic additives and recyclates can be removed quickly, safely and cost-effectively.
Cleaning solutions for individual needs
Three different systems from Schwing are available for this purpose. With the user-friendly and precisely controllable systems, Schwing takes into account the individual needs and the variety of tooling used in the industry:
– Pelletizing dies, extruder screws, screw elements, laser filters and filter discs as well as all plastics: cleaning by means of thermal vacuum pyrolysis in VacuClean and VacuClean COMPACT systems.
– Hot runner manifolds, breaker plates, screw elements, etc., and for all polymers, including high-temperature plastics such as LCP, PEI, PPS or PI: cleaning using fluidized bed technology in InnovaClean systems.
– Large tooling, e.g. large extrusion dies, and all halogen-free plastics: cleaning by means of thermal pyrolysis in industrial burn-off oven systems.
There are numerous benefits for users in plastics processing and recycling, explains Andrew Dickinson: “The use of our thermal cleaning systems significantly increases machine availability. This in turn minimizes interruptions, reduces costs and increases the productivity of our customers.” Schwing sells its technology solutions and equipment worldwide, is constantly improving the efficiency of its systems and adapting the cleaning processes of innovative materials and new machine designs at an early stage.
