Product Description

Split Twin Screw Extruder:It is more convenient to clean barrel and screwIt can more easy to see the mixing and plasticizing state of materials in the screw, and can arrange the screw combination more rationallyMore convenient to eliminate screw overloadIt is more convenient to check the wear of screw elements and barrel. 

In the past, the barrel of the twin-screw extruder is integral and cannot be opened. The split type twin-screw extruder is a split type, which is composed of two halves of the barrel, the lower half of the barrel is fixed on the frame, the upper half of the barrel is connected to the lower half of the barrel by worm gear reducer. Usually, the upper half of the barrel and the lower half of the barrel is bolted by two rows of bolts. When it is necessary to open the barrel, only loosen the bolts and turn the handle of the worm box to open the barrel.

The screw and barrel of Split twin screw extruder adopt advanced “building block” design, screw by various forms of suits on the core shaft screw block, barrel liner set depending on the screw block can be adjusted, thus according to technical requirements such as material variety and combined the ideal form of screw element structure, realize the material conveying, plasticizing, refinement, shear, exhaust, build pressure and extrusion process, so as to better solve the general difficult to balance the so-called screw the contradiction between generality and specificity. Another advantage of the “building block” design is that worn screw and barrel components can be partially replaced to avoid the entire screw and barrel greatly reducing maintenance costs.

What Our Customers Have to Say



Thanks for the hard work of Cowin team. Due to the large project, our company hopes to find suppliers with high cost performance and good quality in China.After the inspection of Cowin, we conveyed the design scheme to cowin. Thanks to the hard work of the design team for several months, the project can be carried out smoothly.After installation and debugging, the machine has met our expectations and we look forward to further cooperation in the future.



TPE Pellets

We received the machine on time. With the help of The After-sales team of COWIN, it has been installed and debugged and put into production, The performance and output of the machine are up to our requirements. Cross-border trade is not easy, but this cooperation has strengthened our interest to cooperate with Chinese manufacturers in the future. Despite the difficulties of the project, Cowin has a good attitude.



Single Screw Extruder

In the field of degradable materials, we are still new, but we are very interested in degradable materials, which is a global trend. COWIN friends provided us with the best services and solutions. Even if we had many questions and doubts, COWIN friends answered them one by one. Finally, we cooperated. Thank you very much for this cooperation. This is our first production of degradable materials. I believe we will have more cooperation with you for degradable materials in the future.




Your machine is great and the service is nice. Every time we cooperate with you, we are happy. Even under the influence of COVID, when we urgently need parts, our production is not affected, because you have provided us with sufficient spare parts inventory and delivered goods quickly. We are very grateful. For us, time is money.


Extensive Experience in Applications

Biodegradable Plastic

Biodegradable Plastic

The main target markets for biodegradable plastic are plastic packaging film, agricultural film, disposable plastic bags and disposable plastic tableware.

Colour masterbatch

Colour Masterbatch

The color masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate made by super-constant pigment uniformly attached to the resin, which can be called pigment concentration.

Engineering Plastic

Engineering Plastic

Compared with general plastics, engineering plastics can meet higher requirements in mechanical properties, durability, corrosion resistance, heat resistance and other aspects, and it is more convenient to process and can replace metal materials.


Filler Masterbatch

Filling masterbatch can be used to process plastic films, garbage bags, shopping bags, vest bags, packaging bags, etc. It has good dispersibility, blown film has no white spots and black spots, high fineness to guarantees product gloss and toughness.

LFT-G Impregnation & Extrusion

LFT-G Impregnation & Extrusion

Long-fiber Reinforced Thermoplastic(LFRT),the length of the glass fiber is bigger than 3mm.while the commercialized LFRT is normally 6-25mm.

Non-crystallization dry PET sheet

Non-crystallization dry PET sheet

Non-crystallization dry pet sheet extrusion has following advantage: Use in producing PET / PLA sheets , no need pre-drying crystallization of the energy consumption and adapt to the material for the production of the second , high yield , low energy consumption, high quality plastics characteristics.
