Abstract: A method and a system is provided for producing a needle of plastic, as well as a needle of plastic, in particular a needle for medical purposes. The method produces a needle having at least the outer diameter of one end being less than 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.

The method for producing the needle includes introducing a melt of plastic into a 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 into the mould cavity whereby the melt solidifies to a needle, and removing the needle from the mould cavity. Increasing the pressure through the feed system provides for meeting specific pressure demands at the entrance of the mould cavity, thereby moulding thin and elongated articles.
