FEATURES
1. Higher Torque
Based on powerful R&D research departement, COWIN has successfully increase the torque degree of gearbox from 5.5 T/A3 to 11.2 T/A3. That means, for the same size extruder, you can get much more output. Meanwhile, the energy is greatly decreased.
2. More Accurate
All the key parts including gears, shafts, screws and barrels are processed by CNC. That will guarantee our machines a more stable running condition. And the advanced installation of the gearbox is our advantage to others.
3. Flexible Screw Configuration
With COWIN extruder, you can change the screw configuration for different applications. That thanks to the flexible screw design, it will help you very easily to do so.
4. Customized Design
COWIN firstly gives the service to customers who need special design for their extruders based on their previous experience. COWIN would like to invite customers to participate in the design of the extruders. You can give your own idea and even can design by yourself.
5. Different Size Available
In COWIN, you can find machinery from smallest screw diameter 16mm to biggest size 160mm.
