A micromachining process for obtaining a desired shape based on the
plastic deformation of solid materials.
Plastic working consists of primary working to produce sheets, rods,
and pipes, as well as the secondary working that produces almost all final products. Fine wires and
tubes and thin metallic foils with dimensions of from several micrometers to several tens of
micrometers play a leading role in general micromechanical fields, and plastic working is important
as a manufacturing technology for these fields. In product preparation, on the other hand,
micro-plastic working makes many contributions in microworking areas but often competes with other
processing methods. The merits and demerits of micro-plastic working depend on the lot size and
accuracy of the products. The most important characteristic of micro-plastic working is its high
productivity. For example, the precision thin metal plate components for electrical components were
conventionally manufactured by etching, but current trends are gradually moving toward press forming.
