BONDING OF TUBES OF THERMOPLASTIC POLYMERS

摘要

A method for bonding a tube (11) into a device (1) each of which is formed from a thermoplastic polymer. The device has first (2) and second (3) solid members in spaced-apart relationship to form a hollow cavity therebetween. At least one linear channel extends through each of said solid members in an aligned relationship, such that a tube (11) may be passed through in sliding engagement, including through the hollow cavity. Molten polymeric composition is injected into the hollow cavity (4) at a temperature lower than the melting point of the thermoplastic polymer so as to bond to the thermoplastic polymer and to the tube to form fluid-tight bonds therewith.
