For many years, COWIN has paid a lot of tuition fees for different materials and different process systems in the field of fluorine plastics, and has accumulated rich experience:
In the design scheme of the special twin-screw extruder for fluorine material and the special design of the structure parameters, such as screw speed, L/D ratio, and torque level.
With development of special screw elements and design optimization of the screw configuration, physical properties of products reach the quality level of foreign products.
The improvement of corrosion-resistant special barrel structure and internal coolign system, make the whole machine more cost-effective.
In order to completely solve the problem of leakage of the end surfaces, COWIN developed special sealing materials and special structures.
Special screw compression structure is developed for thermal stress balance and anti-leakage of hastelloy Cmaterial.
The design of the special venting chamber structure is improved.
Combination and application of high torque gearbox and process Research on the mechanism of vacuum devolatilization process and improvement of vacuum system.
Optimization of the design and structure of the new flow path of the die head and die plate New water ring pelletizing system is designed to solve the problem of corrosion resistance and solve the problem of wear resistance.
New air-cooling die face hot-cutting system is designed not only to solve the problem of corrosion resistance, but also to solve the problem of wear resistance, and to solves the subsequent problem of material drying.
New feeding system is developed.
FEP (F46), PFA, PVDF (F26), ETFE (F40) powder granulation and stabilization.
