Lab Vertical MDO Stretching Machine

This is an MDO (machine direction orientated) film stretching machine that can work online or offline.

Cast film or blown film can be stretched in one direction and it improves the tensile strength, stiffness, shrinking property, and transparency of the film. Compares to those that have not been stretched, the MDO films have special cellular structure and crystal structure which provides excellent barrier property, and it very useful as the barrier film for R&D in lithium battery development. 


Functions of Lab Vertical MDO Stretching Machine

  • Offline film orientation stretching in machine direction.
  • Online  film orientation stretching in machine direction together with extruder and die.

Applications of Lab Vertical MDO Stretching Machine

  • Off-line film vertical stretching
  • Optional one-point stretching or two-point stretching
  • Combined with Lab Precise Cast Film Extrusion Line to realize on-line vertical stretching
  • Different stretching ratio for the film
  • Functional film production and research
  • Optimization of film stretching technology
  • Material stretching property test
  • New material formula development

Features of Lab Vertical MDO Stretching Machine

  • Using independently driven servo motors for preheating roll, stretching roll, annealing roll and cooling roll to precisely control the speed
  • The gaps between the rolls could be adjusted to decrease the necking effect.
  • Using Mold Temperature Controller and oil heating to keep uniform roll temperature
  • Independent 10’ touching screen to easily operate
  • European standard aluminum alloy frame making it light, strong, corrosion resistant and durable
