How To Reduce Wear Of The Screws And Barrels? (一)

Jul 21, 2018

Each plastic material has an ideal plasticizing processing temperature range, so the processing temperature of the barrel should be controlled within this temperature range. The granular plastic enters the barrel from the hopper and first reaches the feed section. Dry friction inevitably occurs in the feed section. When these plastics are not heated enough and the melting is uneven, it is easy to cause wear and increase on the inner wall of the barrel and the surface of the screw. Also, in the compression section and the homogenization section, if the molten state of the plastic is not uniform, the wear also increases.
