  • Twin screw and barrel with parallel design is known for its ability to generate minimal amount of shearing stress between small shaped screws and less rotational rate.
  • It has good plasticizer properties, high output level, low sharing strength, consistency in creating pressure, low wear rate and affordable price.
  • The application of parallel twin screw and barrel can be noticed during processing of PVC items. The utilization of this barrel can enhance production of more than 350 kg of PVC items per hour as the price of parallel twin screw and barrel is comparatively low than its conical shaped counterpart for its utilization of advanced technology.
  • The presence of parallel twin screw can be noticed in pipe, pellet, PVC plate and mold design. The usage of this barrel can efficiently solve problems associated with rust formation, surface wear and high as well as low foaming.
