Accessories: Weighing loss-in-weight integrated feeding unit

Italian control technology, raw material ratio accuracy error ±0.05%, extrusion control accuracy error ±0.3%. Effectively control formulation cost and layer ratio functional stability.
National patented valve shearing design can effectively avoid the problems of raw material stuck, lack of material, downtime and other problems. The patented inclined mixing barrel can effectively avoid the dead angle of mixing.
The operation screen is simple and can store multiple formulas. The formula ratio can be changed within two minutes, and the product thickness and output can be changed within one minute, reducing production losses. Through real-time statistics of raw material consumption, it can effectively assist the production workshop to control raw materials.
Monitor the production status of the extruder in real time to compensate for changes in the quality of extruded products caused by changes in raw material density, heating temperature, screw wear, and extrusion process changes.
