BETTER, FASTER, SMARTER EXTRUSION
The trend in plastic extrusion is rapidly moving towards the use of recycled materials. Of course, these materials typically contain high amounts of impurities and contaminants that need filtering out of the molten material.
Increasing quality and optimizing costs in recycled plastic extrusion
Manual screen changer operation requires personnel, to check filtration process and replace filters; which means increasing costs, frequent system downtimes, low throughput, low quality. An automatic / continuous solution would significantly improve your process and optimize line costs and general management.
We think it’s the key. Materials with high amounts of impurities are hard to filter with traditional screen changers; if your system cannot filter highly-contaminated recycled materials with the utmost efficiency, you cannot make the cheapest choice for your raw materials – neither you can produce top quality extrudate, nor optimize costs. Screen changers have a direct impact on your whole business.
Cofit screen changers can be a strategic choice for you
Cofit can provide you with solutions to get a better, faster, smarter plastic extrusion system. We are certain that screen changers play a key role in post-consumer and post-industrial equipment.
