COWIN EXTRUSION always focuses on R&D of new technology & products, equipment process and manufacturing, and turnkey project of high polymer related processing equipments.
Laboratory twin screw extruder is mainly used in the research and development of polymer plastics, mainly for universities, enterprises and research institutes. The main feature is that the screw diameter is small, which greatly reduces the use of materials in the application and development.
Modular construction barrels combination, self-cleaning screw Combination. Both screws and barrels designed according to building block principle. And the machine’s extensive performance and special purpose could be achieved ideally. Independent control of barrel temperature. A variety of cutting methods that meet the requirements of various materials. Adopt good dynamic system and workmanship can bring excellent machine performance.
Compared with the traditional twin screw extruder, the triple screw extruder not only retains many excellent properties of the twin screw extruder, but also has the following characteristics: 1. Better plasticizing and mixing effect: 2.The length diameter ratio of screw is shorter, the residence and mixing time of material is longer. 3.Higher output: the capacity of triple screw extruder is more than 50% higher than that of the same twin screw extruder.
Combine the high speed and extensive mixing of twin screw processing and the low speed, low temperature, and low shear of single screw processing; Ideal for compounding of heat- and shear-sensitive materials PVC compounds for cable, shoe sole, transparent container, and medical applications EVA shield cable compounds; Carbon black masterbatches of PE, EVA, etc.
Cowin Extrusion has successfully made CSE super high efficient single screw extruder. This kind of extruder has a much bigger capacity, lower energy consumption, meanwhile an excellent anti-wear performance. For pipe extrusion, the energy consumption is 0.25-0.3kwh/kg, while 0.15-0.2kwh/kg for board, sheet and granulating, which is greatly lower than the common single screw extruder.
Cowin Extrusion is a specialized manufacturer and support service provider of twin screw extruders, spare parts, ancillary equipment and complete production lines.
We provide various types of feeders, granulators, material conveying equipment, and other upstream and downstream auxiliary machines.
all graduated from domestic professional colleges in the industry, with ~20 years of experience in design of twin screw extruder
all worked in foreign enterprises, have a wealth of electrical technology experience

Nanjing Cowin screw is designed according to the building block principle, and the combination can
TPU modified granulation process:Twin screw extruder – screen change – water-cooling strand pelletizing granulation auxiliary machine – water trough – dryer – pelletizer – vibrating screen – siloTwin screw extruder – melt pump – screen change – Underwater granulation auxiliary machine – underwater pelletizer – water circulation system – centrifugal dehydrator – vibrating screen – silo
PVC generally needs to be modified and granulated first. The basic principle of modification is to endow materials with functions or improve some properties through additives. PVC granulation generally uses a two-stage machine, the upper stage adopts a twin-screw extruder, and the lower stage adopts a single screw extruder.
ABS (Acrylonitrile butadiene Styrene copolymers) chemical name: acrylonitrile butadiene styrene copolymer. It is a kind
