Co rotating twin screw extruder


Extruders for producing high-quality products from plastics or pharmaceuticals are a very good

technology. Its core component is co rotating twin screw extruder. Because of its modular design, it is very flexible.

It has become one of the world's leading manufacturers of twin-screw extruders.

Only through continuous innovation and listening to users' requirements can it be possible to provide a fully developed product series. For plastic processing, it provides an ideal combination of very high specific torque (15 nm/cm) and high volume (od/id = 1.66).


More output and higher operation safety

The gear box of twin-screw extruder puts forward high requirements.

Since the axial distance between the two extruder screws is relatively close, it must transmit very large torque and counteract the high reverse pressure


Therefore, a very powerful driving concept was used for its twin-screw extruder. High power density is achieved through high-quality process, continuous research and long-term technical know-how. It meets very demanding requirements and is persuasive with maximum torque density.


More splines, better torque transmission

Advantages of asymmetric spline shape: the arrangement of several splines has the same root width and can transmit very high torque. Error can be reduced by setting the assembly direction


Cooling capacity for larger process windows

Twin screw extruders allow an increase in throughput of up to 50% compared to previous models. This means that the energy balance of the processing unit has changed, and in some cases the cooling capacity needs to be increased. The inlet and outlet of each barrel have been doubled, and a complex cooling hole system has been developed to allow more liquid coolant to flow through the barrel, which helps to improve the cooling capacity. Due to the short distance between the cooling hole and the processing room and the counter flow principle, the cooling capacity is fully utilized. The treatment unit is installed by a functional carrier system and integrated cooling pipes. High quality coaxial valve is assembled in the frame, which saves space


Increase throughput by increasing capacity

When running volume limiting processes such as dry blending, pigment formulations, fillers or additive concentrates, the increased volume of the extruder can be fully utilized. With an OD / ID of 1.66, lestrez found the ratio between high capacity and effective energy input products.


More throughput. By increasing the volume, the machine is slightly smaller, but it is conducive to good dispersion. At the same time, it can achieve higher output of the same or even better quality for many formulations


Offers a variety of helical geometry options that can be combined into a large number of variations. Generally, there are conveying, kneading, mixing and other elements. The ability of process engineers enables them to create screw designs for their respective applications. Depending on the geometry, various screw elements are placed and fixed on a screw shaft with a spline profile. Heart of extruder
