Product Details

Mini twin screw extrude works co-rotating, a mode based on innovative design assumptions, modern components and years of experience gained in the plastics processing industry. Co-rotating extruders show improved separation and mixing capabilities and are best suited for melt blending operations. Mini twin screw extrusion machine is well known that the control and reliable measurement of the melt temperature in each zone of the extruder is a key factor in determining the quality and reliability of extrusion process studies. Our micro twin screw extruder can work with any thermoplastic, polymer and other materials over a wide range of temperatures and screw torques, and with their versatile adaptability and simple system operation for almost any processing task, they are called “Excellent Research Instrument”.

Micro twin screw extrusion machine can be equipped with an accurate tension measuring device to measure the force acting in the longitudinal direction of the screw. This mechanism also expands the possibilities for conducting research. Almost all materials can be studied, including the plastics, medical, pharmaceutical and ceramic industries. In practice, small twin screw extruder achieves and stabilizes within a short period of time to changes in the parameters set by the scientists, resulting in reliable scale-up and reduced time-to-market. Small twin screw extrusion machine offers flexible configurations from small batches to pilot scale or small batch production and is ideal for research and development in the fields of polymers, pharmaceuticals, bio and nanotechnology. Lab plastic pelletizer cover a wide range of process requirements, even for the most difficult formulations.

  • Specially manufactured screw and barrel to guarantee precision and quality
  • International brand variable speed control motor to precisely control the screw rotating speed
