Blown Film Line

ชุดทดสอบวัตถุดิบจาก Blown Film

The OCS blown film extrusion lines are used to produce high-quality blown films to measure impurities, haze, gloss, density and other characteristics. Adjustable wooden grids and Teflon coated rolls convert the film bubble into a flat layer film while some guiding rolls prevent wrinkles. An optical device measures the width of the flattened film and controls the diameter of the film bubble. The tower height is electrically driven and adjustable. The take-off nip rolls are driven pneumatically and their temperature is optionally controlled.

All parameters of the system, e.g. extruder speed, temperature, haul-off speed, film width, film bubble ratio, etc. are stored in the touch panel control system, which guarantees the reproducibility of the film quality at any time.

Possible testable polymers include materials such as PP, PET, PC, HDPE and LDPE and can be in the form of pellets, powders and flakes.

  • Cleaning positions of the Measuring Extruder (ME) can be approached via electric motor
  • Modular architecture of the Modular Film Analyser (MFA) to facilitate customisation of additional measuring and test devices
  • Automatic control of the bubble diameter according to the preset film width
  • Operation via touch panel with data trend as well as optical and acoustic alarm functions
  • All system parameters are monitored and saved in the touch panel control system
  • Measuring Extruder (ME20/ME25/ME30/ME40/ME45) with blown film die 30–80 mm
  • Modular Film Analyser with Blown Film Tower (MFA-BFT)
  • Film Surface Analyser (FSA100V2/FSA200V2)
