Double-piston continuous screen changer is designed to consist of two pistons with each containing a filter screen,the two screens work at the same time,when a screen change is required,one of the pistons is moved out while the other remains in the operating position,and the melt flows continuously through the other piston,the pressure fluctuation is small,thereby meeting the requirement of high quality production.
