• Resumen

  • Standard injection micro-moulding process, dedicated for mass production, it is often uneconomical for low-series or single-piece production.

    Recently available ultrasonic-micro moulding technology, which can plasticize only amount of polymers required for one part seems to be a potential alternative to standard injection micro-moulding technology especially by limiting the waste of materials during small production runs. This thesis focus on increasing knowledge about the ultrasonic micro-moulding process of polymers, such as polyphenylsulfone PPSU and polyetheretherketone PEEK, establishing relationship between the process parameters and the key aspect of the high performance parts such as mechanical properties.
