21.7mm Polymer Formula Pelletizer Plastic Pelletizing Machine Lab Twin Screw Extruder

 Characteristics of twin screw extruder

The screw arrangement are adopted “toy bricks” principle, which assembly according to different machine L/D, different feeding way, different barrel and screw combination, different screen changing and cutting way, different electrical control mode, etc. it meets the features of material and technological process. Give consideration to the plastic universality commonality and appropriability.

Yongjie laboratory mini extruder SJSL20 is widely used among our customers of universities, research center, and factory R&D department for the testing of formula, compounding etc.
