Fully Automated
The fully automated twin-screw extruder is a kind of continuous processing equipment. It combines the functions of feeding, melting, mixing, exhaust, pressure holding and extrusion, etc for 5L~30L HDPE jerry can. It is suitable for high-speed and high-efficiency material conveying, mixing, and plasticizing, and has the characteristics of a wide range of applications.
The extruders are widely used in the field of polymer modification, plastic+rubber blending, plastic cunctional masterbatch, glass fiber reinforcing, cable materials compounding, and so on. They are also the first choice of continuous mixing equipment in polymer synthesis.
In addition, they can be applied to the biodegradable plastics production industry. The process can be carried out on different kinds of polymers, such as PVC, PET, PP, and PE. The output is also very good, and the molded products can be made into various shapes.
Compared with the single-screw extruder, the biodegradable twin-screw extruder has advantages, such as easy operation, higher efficiency, high production capacity, and low energy consumption. Its main advantage is that it can produce a large amount of product at the same time, which can save the costs of purchasing raw materials and processing equipment.
To reduce the environmental impact of the biodegradable twin-screw system, it should be equipped with a devolatilization device that removes volatile components from the feed port. This device can be a screw filter, a separator, or a vacuum pump. It can be used to remove monomers, oligomers, and water from the feed. It can also be used to separate the re-meltable and non-re-meltable parts of the raw materials.
The devolatilization efficiency depends on the surface area and residence time of the resin, and the mass transfer coefficient of the volatile component. The devolatilization process is mainly performed through surface renewal, which involves distributive mixing between the barrel and the screw, which enhances the mass transfer of the volatile component.
Therefore, it is important to study the effect of the screw pitch on the devolatilization efficiency. Moreover, it is necessary to develop a simple and versatile calculation method that can be used in industrial twin-screw extrusion.
To determine the effect of the screw pitch on the devolatilization, we simulated the flow rate and the rotation speed in a corotating twin-screw extruder with different screw pitches. Then, we compared the devolatilization efficiency with the experimental results. The simulation and the experimental results agreed well, with a relative error of 6.5%.
Strong Durability
The biodegradable twin-screw extruder is a high-quality machine that can be used for a long time. It is a perfect choice for those who need to produce biodegradable plastics that can be recycled. It can also be used for manufacturing other products such as medical devices and food packaging.
Compared to traditional plastic granulators, the biodegradable twin-screw compounding extruder is very strong in its durability. This is because it has a special design that can be used for a long time and is very easy to operate. It can also be used to produce a variety of different products, such as plastic bottles, tubes, and films.
In addition, the biodegradable twin-screw composite extruder or Plastic Pallet is a great option for processing waste plastic, such as recycled polyethylene (RPE) and polyester-based fibers. It can also be used to process other wastes, such as aluminum and copper.
Another advantage of the biodegradable twin-screw compounder is that it is designed in a modular format, which allows you to mix different screw elements. This is especially useful for mixing biodegradable resins with a variety of additives.
The biodegradable resins that are produced by using the biodegradable twin-screw granulator have a much higher melting point than those that are made from virgin materials, which can help them retain their strength for longer periods of time. This is particularly important for applications that involve heat.
In order to increase the melting point of the resins that are produced by using the biodegradable granulator, it is important to use a high-quality nozzle. It is recommended that you use a nozzle with a good flow capacity and an accurate profile. It is also important to make sure that the nozzle is able to maintain an accurate temperature.
Moreover, the biodegradable twin-screw plastic granulator is designed with a vacuum system, which can increase the material's surface area. This increases the ability of the extruder to reduce shear force and exchange rate, thus allowing it to process the material more efficiently. It also has a stronger self-cleaning ability, as it can keep the nozzle clean and prevent it from clogging.

With a growing need for recycled plastics in India, the industry has been looking for a solution that can efficiently and cost-effectively produce a variety of plastic compounds. MGPL’s Co-rotating Twin Screw Extruders are ideally suited to process these compounds that comply with the highest sustainable development standards.
MGPL’s biodegradable twin-screw extruders feature a high-performance drive system to increase throughput and a low-viscous barrel design for maximum energy efficiency. Moreover, user-friendly barrel covers fully insulate the process section.
The extruder can be easily operated with the aid of a control unit. A programmable process controller controls the temperature and feed amount. A touch screen display allows the operator to view and modify all operating parameters, ensuring precise control of production quality and throughput.
In addition, the extruder can be equipped with a molten resin reservoir that is used to reduce the production time and enhance the quality of the final product. This feature has been proven to increase a resin production yield by 30% while reducing the production costs by more than 50%.
To further ensure high performance, the twin-screw extruder can be equipped with a reverse kneading block (RSR). This feature has been found to improve the reaction extrusion rate and increase the melt index of the final product by increasing the residence time of the reactive polymer and chain extender.
Another feature of the extruder is that it can be operated without a molten resin reservoir by simply replacing a small molten resin reservoir with a non-reactive molten resin reservoir. This feature has been found to reduce the production time and enhance the quality as well as ensure that the resin is free from impurities with PE Breathable Film Production Line.
Furthermore, the extruder can be used to manufacture a variety of products from biodegradable, renewable materials. It can be used to produce fiberboards, plastics, and specialty chemicals for a variety of uses. It can also be used to manufacture bio-based materials for food packaging and other industrial applications.
