Plastic Film and Sheet Extruding Equipment

Product introduction video of plastic machines

The business started from a technical tie-up with Reifenhauser Inc. in 1963. We now possess a wealth of experience in all plastic extrusion fields such as food packaging materials, housing construction materials, home appliances, and industrial materials.
Hitachi Zosen possesses a lineup of products that meet the needs of the times. We provide equipment for high-temperature super engineering plastics, equipment for high-precision optical sheets and film, etc. For the next 50 years and 100 years, Hitachi Zosen will continue to meet the software and hardware needs of our customers by utilizing the technology and experience which we have cultivated, and by acquiring the latest technology and developing the latest equipment.

Outline of machine

  • Application resin: Special PC, PPS, PEEK, etc.,
  • Dimension of product: thickness 20 - 400 µm; width 500 mm
  • Forming speed: maximum 18 m/min.


  • A compact design concept that is multi-functional as well as multi-purpose
  • Produces a superior product with high transparency, low residual strain, and flatness
  • A maximum heating temperature for the extruder, gear pump, and die head of 450°C
  • The roll unit has an ultra-elastic flexible metal roll (UF roll) covering and a maximum heating temperature of 300°C
  • The roll driving unit has a super-precise reduction gear system, resulting in lower vibration as well as super-smooth roll rotation
  • Enables embossed or patterned finishing as well

Metal elasticity roll (UF roll)

By reducing the thickness of the metal roll comprising the outer cylinder, this proprietary development of Hitachi Zosen enables stable roll pressure formation even under low linear pressure conditions. This makes it possible to obtain film products with high gloss, high transparency, low residual strain, and outstanding smoothness.
Both water and oil can be used as the heat medium. This technology is mainly used in the manufacturing of films and sheets for optical applications. Hitachi Zosen also offers a lineup of ultra-high temperature UF rolls that support super engineering plastics.

Chronodie (high-performance T-die)

The tip of the die lip is lengthened in order to improve moldability. Furthermore, the distance (air gap) between the roll crimping part and the tip of the die lip is minimized.


  1. 1Improved thickness accuracy (both TD and MD directions)
  2. 2Lowered phase differences and reduced unevenness of low phases
  3. 3Improved yield by reducing neck-in amount
  4. 4Improved moldability
  5. 5Possible to mount a heat bolt automatic adjustment lip device
  6. 6Possible to install in existing facilities


  1. 1Continuous pattern transfer both inline and offline
  2. 2Simultaneous transfer of multiple different sizes and pattern shapes
  3. 3Pattern transfer to film as small as 100 µm
  4. 4Compatible with both flat film and taper film

General-Purpose Film and Sheet Forming Systems
