Twin screw barrels are vastly produced at our plant since 1990s.
Some sizes include 67/22， 68/25，114/32， 92/28， 92/32， 114/32， 90/16， 90/22， CM80，40KK, 75/32, 81/17, CM58; 24/52, 45/90, 45/100, 50/105, 51/105, 55/110, 55/120, 58/124, 60/125, 65/120, 65/132, 68/143, 70/135, 70/140, 75/150, 80/143, 80/156, 92/188, 105/216, 110/220
Our standard conical twin screw barrel 45/90, 50/105, 65/132, 80/143,92/188, 110/220 ect.
Per different additive, for example low CaCo3, medium CaCo3, high CaCo3, we design differently to offer the best performance and as longer service time as they could.
Parallel Twin Screw Barrel (2P)
Parallel twin screw barrel are for extrusion machines making profile , tube, Sheet, foam, plastic compounding etc, processing all kinds of polymer with a larger output, which is able to reach tons per hour at a specific size.
