0 50 mm using a moulding system having an assembly comprising a feed system and a mould cavity the method includes introducing a melt of plastic into the feed system increasing the melt pressure gradually during melt passage through the feed system passing the melt into the mould cavity whereby the melt substantially fills the mould cavity cooling the melt in the mould cavity whereby the melt solidifies to a needle and removing the needle from the mould cavity application_number US 83118804 A description the moulding system 1 may be any injection moulding system suitable for injection moulding of small articles fig1 shows a schematic view of a injection moulding system 1 the system 1 comprises a granulate reservoir 2 which reservoir 2 contains the plastic in a solid phase the granulate is at the bottom 3 of the reservoir 2 which leads through a feed tube 4 into a chamber 5 in this embodiment a thermal conduit in the form of a chamber 5 comprises a screw 6 the screw 6 is rotated by a driving shaft 7 connected to a motor 8 an instrument for measuring pressure 9 is connected to the chamber 5 in front of the screw 6 for monitoring the pressure building by the screw 6 as the screw 6 rotates the granulate is led towards the entrance of an assembly 10 during the rotation of the screw 6 the granulate is being heated and becomes a plastic melt the temperature is monitored by a temperature sensor 11 the temperature of the assembly 10 is monitored by a temperature sensor 12 and is controlled to be from 50 to 350 u00b0 c preferably from 120 to 140 u00b0 c according to the material used in the moulding.
