**Advantages
1. Parallel twin screw and barrel has the advantage of lower rotation speed, smaller shear stress between the small screw
2. Good plasticization, high productivity, small shear force, stable pressure , less wear and tear and low cost.
3. Parallel twin-screw and barrel is widely used in PVC products processing, especially for the production of PVC products with the output over 350Kg / h, because the parallel twin-screw and barrel costs less than conical twin-screw and barrel while it has more mature technology.
4. Parallel twin-screw and barrel is successfully applied in PVC plate, pipe, profile, pellet and mould, at the same time, it solved the technical problem of low foaming, high foaming, high filling, wear and corrosion.
we can make any specification of extruder screw barrel and injection screw barrel for Haitian, Demag, Engle, Klaus-maffei, Nigro bossi, arburg,NPM, BOY, Husky, Fanuc, billion, Sumitomo, Nippon Steel, Toshiba, Nissei, Mitsubishi and etc. We also can supply all types of screw and barrel according to your different requirements.
Our screw barrel can ensure the well performance and low energy consumption of extruder and Injection molding machine. We insist on the principle of quality first, honest to customers, the quickest service for customers” to improving us, our goal is to satisfy our customer
