Application of micro-forming technology in plastic processing

The rapidly developed MEMS market gives the micro-system engineering a wide space for its development and application, The need for metal micro-metal parts is being increased gradually. Combined with micro-forming technology and conventional plastic processing, the micro metal parts can he manufactured at high precision and production rate. However, it asks for the higher requirement on the micro-forming and plastic processing technology. The influence of scale effect makes the micro-forming a new research field, so the conventional plastic processing theory is impractical any more. After introducing the concept of micro-forming, its application, development and research methods in plastic processing are discussed in this paper. Furthermore, the key techniques of the micro-forming are set forth.
