A mould made by Männer will be used to produce two 2.35g syringe barrels made from COP in a cycle time of around nine seconds. This will involve lateral injection via a needle shut-off nozzle. COP is transparent and has similar barrier properties to glass, but is almost unbreakable and cost-efficient to produce. In a subsequent step, the syringe barrels can be pre-filled, assembled and packaged ready for use.
