Main factors affecting plasticizing quality The main factors affecting plasticizing quality are: length-to-diameter ratio, compression ratio, back pressure, screw speed, and barrel heating temperature, etc.
We firmly believe that the most reliable quality and the most competitive prices, the most pragmatic style will be let us become the most dependent on your business partners.
