Twin Screw Extruder, also named Lab Twin Screw Extruder can be applied to the mixing, plasticizing and extrusion of engineering plastics, modified plastics, master batch and other high polymers with the features of uniformly dispersed, plastics coloring and filling to modify.

Twin Screw Extruder for Lab and R&D DW5210   

Twin Screw Extruder for Lab and R&D is developed on the basis of single screw extruder. It has been widely used in extruding products due to its good feeding performance, mixing plasticizing performance, exhaust performance and extrusion stability

Follows are features of Twin Screw Extruders for Lab and R&D:

  • Miniaturization of furnace body;
  • The mandrel of screw is made of 40CrNiMoA chrome-molybdenum alloy tool steel, treated by nitriding, hardening and tempering, chromium plating and super-fine grinding, resistant to corrosion.
  • The combination of screw components is building block type, can be arranged according to the technology of material. Different shear force and mixing effect can be achieved for production of diverse materials;
  • Charging barrel adopts bimetallic material, hard alloy wear-resistant inner sleeve with replaceable lining and multi-section barrel assembly arranged according to different functions;
  • High precision temperature sensors to monitor the melt temperature change;
  • PLC programmable LCD touch control panel, with all parameters are freely controlled and extruding process are dynamically displayed.


Application of Twin Screw Extruders for Lab and R&D 

Lab Twin Screw Extruder can be widely used in PE twin screw extrusion, PP twin screw extrusion, PET twin screw extrusion, etc. The processing fields of blending modification, filling modification, dispersing agent, fibre reinforcement, blending reaction, polymerization reaction and exhaust devolatilization for plastics are ideal experimental equipment of high accuracy and high performance. It use below area

  1. Mixing and mixing extrusion granulation of general plastics, engineering plastics and elastomers;
  2. Blending modification and reactive extrusion of composites;
  3. High-efficiency mixing of polymer alloy;
  4. Polymer filling enhanced and modified
  5. Research and development of new products and new formulations;
  6. Optimization of production process parameters;
  7. Small production line.
