Experimental extruder is suitable for formula development, small batch of preliminary samples of mixing extrusion granulation experiments, can be widely used in scientific research institutes, universities and colleges laboratories, as well as enterprises and institutions R & D center. Movable base, integrated design, compact appearance, full-featured; plug-and-play design, easy to install and debug: touch control system, easy to operate.

The required combination form can be adjusted according to the processing task, and it can flexibly respond to different formulas:The process parameters are stable and reliable, and can be copied to batch industrial production. Suitable for filling modification, glass fiber/carbon fiber reinforcement, color masterbatch, plastic alloy, functional masterbatch, all kinds of cable materials, reaction extrusion, etc.
   The screw arrangement is adopted "toy bricks" principle, which assembled by different machines L/D, different feeding way, different barrel and screw combination, different screen changing and cutting ways, different electrical control mode etc. It meets the features of material and technological process.Consider the plastic universality commonality and appropriability.



Strand pelletizing is a widely applied pelletizing  process,suitable for almost all  materials. This process features simple equipment structure and convenient operation and maintenance. For strand  pelletizing  process,usually  water  bath,air  knife,pelletizer  and vibration sieve are provided.The system is in module design,so users can add a hot air drying chamber,pneumatic conveying system,silo or other equipment to it as options according to process requirements.  This product is suitable for Water  cooling  strand  pelletizing  line  of  all  kinds  of  thermoplastic  general  engineering  plastics and modified engineering plastics,such as ABS,PA,PC,PE,PET,POM,PP,PS,etc.,including glass fiber reinforced and inorganic filled  thermoplastic  extrusion.


This process is mainly used for pelletizing of materials that are likely to absorb water,or are  not easily  dewatered or dried,or to which moisture content may result  in  adverse  effect  on quality.As materials never contact with water during the whole pelletizing process,there is no need to remove water Conventional  configuration  for  the  equipment  includes:pelletizer,three-stage air  conveying system and vibration sieve. The product is widely used in wood plastic granulation and PVC modified materials,such as PP/PE+wood powder,PVC+CaCO3,etc.

Water-ring hot face pelletizing system is suitable for many thermoplastic materials.Because the water ring is formed at the periphery of the mold,the mold does not contact with the cooling water.This feature ensures the uniformity of the temperature of the mold,ensures the consistency and uniformity of the particles,and is insensitive to short-term  polymer  flow interruption.Ensure the appearance of the material particles.
Conventional configuration for the equipment  includes:pelletizer,spin  dryer,vibration  sieve, air conveying and silo.Customers may add it with fluidizing bed ,packaging machine,etc. The product is widely used in PP/PE+CaCO3,Talc,Titanium dioxide and other  high filling masterbatch.


Underwater pelletizing  system is suitable for most materials.Especially  in  the  completion of other granulation system  can  not  complete  the material,such as TPV,TPU and other elastomers,can show outstanding  performance.In  addition,because of  its  limited  factors  in  yield,it is more suitable for super large yield granulation than other granulation methods.Conventional configuration for the equipment includes:underwater cutter,water circulation system, spin dryer,vibration sieve,air conveying and silo.
