COP material replaces glass in injection moulded syringe barrels

  • Electric Allrounder for clean room production
  • Substitution: COP replaces glass in syringe barrels
  • COP is unbreakable, biocompatible & blood compatible

Arburg will present a sophisticated medical technology application with an electric Allrounder 370 E at the upcoming Equiplast in Spain.

The injection moulding machine with a clamping force of 600 kN and a size 170 injection unit features a clean air module above the clamping unit to ensure clean production conditions. Using a mould from Maenner, two 2.35 gram syringe barrels will be produced from COP (Cyclic Olefin Polymer) via a side gating with needle type shut off nozzle in a cycle time of around nine seconds. COP has similar barrier properties to those of glass, but it is unbreakable and less expensive to manufacture. As a cyclic olefin copolymer, this material is transparent, biocompatible, blood compatible and only slightly water-absorbent. COP is therefore extremely well suited to the production of syringe barrels, which can, for instance, be produced and packaged already pre-filled in a downstream operation.

Another exhibit, an Allrounder 420 C Golden Edition will manufacture mobile phone covers with a single-cavity mould from Hasco. Here, the cycle time is around 30 seconds.
