The planetary screw extruder is an advanced plastic processing equipment that is widely used in plastic product processing and food processing due to its unique planetary screw structure and efficient mixing and plasticizing ability. The planetary screw extruder mainly consists of three parts: an extrusion system, a feeding system, and a temperature control system. The extrusion system includes a central screw, planetary screw, and barrel, which are the core components of the extruder. The feeding system usually uses a forced feeding device to ensure that the material enters the extrusion system at a stable rate. The temperature control system is responsible for adjusting the temperature of the screw and barrel to ensure the melting and plasticizing effect of the material. With the continuous advancement of technology and the increasing market demand, planetary screw extruders will continue to play an important role in industrial production.
Thermal sensitive material
Hard and soft PVC calendering machines provide discharge.
It can also be used for extruding ABS, TPO, and TPU, and filling mixtures of polyolefin smoke and adhesives.
We have achieved results in the powder coating industry.
The chemical and food industries are also expanding their applications.
It has the characteristics of good plasticizing quality, excellent self-cleaning performance, high yield, and long service life.

Product advantages:
The planetary screw extruder adopts a planetary screw structure, and the material is subjected to strong squeezing, rolling, and shearing effects between the screws, causing the raw material to quickly melt and uniformly plasticize. This design greatly improves the mixing and plasticizing efficiency, and the heat exchange area is more than 5 times larger than that of a single screw extruder. The planetary screw extruder has efficient mixing capacity, relatively small shear action, short material residence time, and effectively prevents material degradation, making it particularly suitable for processing heat-sensitive materials. Due to the special design of the planetary screw, the extruder has lower energy consumption during operation and higher output, improving production efficiency and economic benefits. In the field of plastic product processing, it can not only effectively handle conventional plastic raw materials such as polyethylene, polypropylene, etc., but also excels in handling heat-sensitive materials that are sensitive to temperature and easy to degrade. These materials often face many challenges in conventional processing, such as uneven melting and quality degradation. However, planetary screw extruders, with their low shear and efficient mixing characteristics, can achieve high-quality and high-efficiency processing while protecting material properties.
