Advantages of the high efficiency single screw extruder:;
Compare to traditional single screw extruder, COWIN has greatly improved the design and know-how of the single screw extruder, making the capacity almost double while the energy cost is half. This not only increases the efficiency of extruder itself, but also save production cost for end-user.
Modular Single Screw Design
In order to solve the problem of some abrasive material processed by single screw, COWIN has originally innovated modular single screw extruder. The whole screw Is composed by small pieces of different screw element like twin screw. With this new design, customer doesn’t have to change the whole screw if it is worn by aggressive materials, instead, you just need to change some pieces of the screw elements where is seriously worn. This will save your cost too much.
The other advantage of this modular screw design is, since the screw is modular like twin screw, then we can install different pieces with different functions. This will help you to get a better plasticizing and dispersion products.
