The difference is that it substitutes a fluid in place of the thick rubber pad as in figure 20 29.
The rubber pads can have a general purpose shape like a membrane.
Although a large number of machine components are made from sheet metal with a thickness of up to 2 mm production of such parts is not economically viable in traditional dies which are designed for mass production.
The rubber die is forced on the blank and deform the blank into require shape.
The rubber pad forming process is also called as guerin process.
The pressure over rubber membrane is controlled through out the forming cycle with max pressure up to 100 mpi as a result the friction at the punch cup interface increases this increase.
Hydro forming process hydro forming hydro forming is similar to the guerin process.
During the rubber pad forming process the punch deforms the blank and apply large pressure 100 mpa over the blank.
Rubber pad forming rubber pad forming rpf is a metalworking process where sheet metal is pressed between a die and a rubber block made of polyurethane.
The rubber pads used in the process are made of hard urethane with dimensions of 43 inches by 51 inches each about 1 5 inches thick.
Under pressure the rubber and sheet metal are driven into the die and conform to its shape forming the part.
The form block is then machined according to each customer s unique specifications.
The die is placed on lower bed and top of that soft die of rubber is placed.
Our rubber pad forming process begins with form block a material made from resin board aluminum or plastic.
Sheet metal parts are deformed by the stamping process.

In bending and embossing of sheet metal the female die is replaced with rubber pad hydro form or fluid forming process.
