1. Adopting a new type of high-efficiency and energy-saving spinning beam. 2. Adopting a bottom-mounted、high-pressure、 self-sealing and cup-shaped component, which improves the uniformity and insulation of the melt flow inside with uniform plate temperature and high spinning efficiency. 3. It uses a cross blowing/ circular blowing equipment with uniform and stable wind speed to ensure the good yarn evenness. 4. Adopting a high-precision hot roller stretching system, with uniform temperature in the working zone of the hot roller surface and low energy consumption. 5. It uses internationally-renowned brand converters and electrical components. 6. Adopting a high-precision automatic switching winder, with a high success rate of switching and excellent bottom yarn rewinding and tail performance.
