◆The drawer type and fixed adjustment structure of the internal inserts can realize the conversion of different composite layers and different composite ratios in production, and the composite layer ratio is more uniform , which can meet the requirements of multi-layer composite production of various materials.

◆Multi-channel online adjustment technology avoids waste and loss caused by shutdown adjustment, convenient operation and high adjustment accuracy.

◆Precise internal flow channel design and surface coating technology enable the quality of extruded products to be precisely controlled.

◆Meet production conditions such as anti-corrosion, heat resistance and wear resistance, and have the characteristics and strength of adapting to the rheology of melt polymer.
