Twin screw experimental extruder
The company has always been in the forefront of twin-screw technology innovation, leading the introduction of a new generation of high precision, high self-cleaning, high transport rate, low processing color change and other characteristics in one of the new parallel co-screw extruder set, the unit in production capacity, Production efficiency, material color processing changes, energy conservation and operation optimization have been greatly improved, and this is the market * for this, transparent, white materials and color masterbatch processing professional equipment, the production of products to achieve high performance, True color, characteristic of low oxidation rate;
Characteristics:
(1) High precision: the machining control accuracy of gear box, cylinder, core shaft and thread element are all in high standard range or even zero position;
(2) High self-cleaning: special thread curve design, reducing waste and yellowing of materials, material processing basically no need to remove screw cleaning, has prominent self-cleaning function, directly refueling extrusion, each alternation material quantity is less, Can produce qualified finished products;
(3) High conveying: greatly reduce the backpressure backflow at the head of the conveying material, achieve higher conveying power, and increase the output of 10-20. The equipment has high precision, good stability and long service life, which embodies the performance that ordinary equipment can't be realized.

Twin screw extruder
Product Description: parallel twin screw extruder, patent for plastics blending, surname, filling, enhancement, etc.
Co-rotating twin screw extruder has best dispersing and compounding for all the materials. Modular design can make the machine changed according to the materials and the process technology easily. It’s possible for one machine reach the extensive performance and special purpose in many place.
TE series included screw diameter from ∮16mm -∮160mm. Different processing demand can be satisfied by our different screw speed and different torque output.
Special design for the frame with special pats makes the machine installation easily and smoothly when running.
Hydraulic screen changer, non-stop screen changer, hinge die are available.
Various feeding system normally are volumetric feeder, gravimetric feeder can be used for more precise.
Power transmission system:
Newly strengthen design, Speed reducing and torque disturbing integrated.
High torque gearbox from Italy used for the machine can improve the capacity of the machine and the safety torque make the machine long life.

High precision twin screw extruder
The company has always been in the forefront of twin-screw technology innovation, leading the introduction of a new generation of high precision, high self-cleaning, high transport rate, low processing color change and other characteristics in one of the new parallel co-screw extruder set, the unit in production capacity, Production efficiency, material color processing changes, energy conservation and operation optimization have been greatly improved, and this is the market * for this, transparent, white materials and color masterbatch processing professional equipment, the production of products to achieve high performance, True color, characteristic of low oxidation rate;
Advantage:
1) High precision: gear box, cylinder ,spindle, screw element processing and precision are within the scope of the high standards and zero;
2) High self-cleaning: special thread curve design, reduce the waste materials ad yellowing, basic don’t need to dismantle the screw cleaning materials processing, has the outstanding function of self-cleaning, refueling extrusion directly, each alternate feed rate is less, can be a qualified finished;
3) High delivery : conveying material greatly reduce the nose back pressure backflow, to achieve higher transmission force, improve the yield by 10% to 20%;
Equipment of high precision ,good stability, long service life and reflected the general performance of the equipment can’t be achieved.
