In the international automotive manufacturing market, fine blanking (FB) provides a state-of-the-art technology far superior to any other techniques in terms of accuracy, quality and economy.

Principles of FB

The FB machine is based on the principle of hydrostatic pressure that plastic deformation of metal is increased by application of high pressure. This principle is based on the studies of Dr. Bridgeman, a U.S. scientist who won the 1964 Nobel Prize in physics. The principle is now widely known in many fields.

FB Features:

� Provides a clean-cut surface without the need for secondary machining such as milling.
� Ensures stable production with high quality and precision.
� Permits three-dimensional composite processing (coining, semi-shearing, bending, drawing)
� Assures better flatness than conventional press techniques.
� The FB requires special presses featuring high accuracy and rigidity as well as precision tools.
� The FB press uses three independently adjustable pressures (Triple Action Mode) for blanking operation.

Products Available

� A wide selection of presses is available. You can choose the product best suited to your particular work requirements, which depend on the shape, quality and thickness of your work pieces.
� Two basic structural types of FB tools are available: a moving punch type and a fixed punch type. The fixed punch tool is mainly used for multi-punching and progressive punching, while the moving punch tool is employed mainly to produce large components.
� There are ten types of hydraulic presses ranging from 1600 kN to 12,000kN. Two mechanical presses of 1,000 and 1,600 kN are also available.
