Top 10 dual screw extruder Suppliers in China

Introduction to Dual Screw Extruder

A dual screw extruder is a crucial piece of equipment in the plastics processing, chemical, and food industries. It consists of two parallel screws rotating within a barrel. The design of the screws can be co - rotating or counter - rotating, and they can have different configurations such as intermeshing or non - intermeshing.

The main function of a dual screw extruder is to mix, melt, and convey materials. The two screws work together to provide high - intensity mixing, which is essential for compounding polymers with additives, fillers, or other polymers. The extruder can handle a wide range of materials, including thermoplastics, thermosets, and even some food products. It is widely used in the production of plastic pipes, profiles, films, and masterbatches, as well as in the modification of polymers to improve their performance.
