  • Method and system for the production of a plastic needle
    Patent number: 6767496
    Abstract: A method and a system is provided for producing a needle of plastic, as well as the needle of plastic which includes a needle for medical purposes. 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.
