High-Performance Twin-Screw Extruder for PVC Production - Top China Suppliers & Factory

Introducing our advanced twin-screw extruders, a superior evolution from traditional single-screw extruders. Designed for exceptional mixing and plasticizing capabilities, these machines are ideal for the molding and processing of a wide range of plastic products, Our dual-pass dry extruder features two parallel twin-screws meticulously positioned within the screw barrel, ensuring a tight fit for optimal performance. As a leading supplier and factory in China, we are committed to innovation, and our technical team has rigorously tested various configurations to establish a unique screw combination sequence. This innovation leads to enhanced efficiency, requiring less mechanical energy while maintaining high output rates, With the ability to operate at speeds exceeding 500 rpm, our twin-screw extruders deliver around twice the work efficiency compared to single-screw models. They excel in processing high-viscosity and heat-sensitive materials, showcasing distinct technical advantages that set our equipment apart in the market. Trust us as your reliable partner for premium twin-screw extrusion solutions in China

Product Detail

Center's self-developed twin-screw basic equipment is also very convenient for subsequent maintenance. Internal problems can be discovered at any time for effective repair and replacement. Assembling the screw also greatly reduces the maintenance cost and time of replacing parts and avoids unnecessary waste.

Advantage

Suitable for processing and manufacturing products of various materials such as PVC, wood-plastic profiles, various pipes, thermosetting plastics, heat-sensitive materials, etc.
Excellent melt uniformity and low melt temperature.
Low energy consumption AC motor.
Screw diameter, high performance, extremely space-saving.

Classification

Twin screw specifications: SJ51/105, SJ65/132, SJ80/156, SJ90/188

Co-directional meshing, counter-meshing and non-meshing types in twin-screw extruders.

Nissan maintenance

After 500 hours of use, there will be iron filings or other impurities in the reduction gearbox. Therefore, the gears should be cleaned and the reduction gearbox lubricating oil should be replaced.

After using it for a period of time, conduct a comprehensive inspection of the extruder to check the tightness of all screws.

If there is a sudden power outage during production and the main drive and heating stop, when the power is restored, each section of the barrel must be reheated to the specified temperature and kept warm for a period of time before the extruder can be started.
