The transition from a linear economic model to a circular economy represents one of the most significant industrial shifts of the twenty-first century.

In today's world of increasingly scarce resources and rising environmental awareness, plastic recycling has become a core issue in the transformation of global manufacturing.

In the plastics processing industry, PE recycled pellets are widely used in the production of various plastic products, such as packaging materials, pipes, plastic containers, and industrial products, due to their environmental friendliness and resource r

During the production process, the color of PE recycled pellets should be tested regularly and compared with the target color.

The melt-extruded strip plastic needs to be cured by water or air cooling, and then cut into uniform granules by a pelletizer.

Traditional extruders maintain the melt temperature by electric heating or gas heating, resulting in significant heat loss and low temperature control accuracy.
