The Cold Forming Process
Cold forming is a process where room temperature material is forced into a die. The forces are very high (500 ton). Because of the high forces the material cold flows into the die. An infinite number of shapes can be created using cold forming. This process can run at high speeds on the order of hundreds of parts per minute. Because the process is done at room temperature and at high speeds it can be very economical. Image’s manufacturing methods can provide custom shapes economically even at relatively low volumes.
Cold Forming Advantages
- Cold forming can Can be used to create complex shapes. An assembly with two or more pieces can often be formed as a single piece.
- Cold forming produces Produces minimal scrap. Because there is no cutting to achieve the desired form cold forming produces almost zero scrap.
- Cold forming creates Creates stronger components. Cold working can raise the tensile strength of the component. Additionally, since there is typically no cutting as in a screw machine process, there are no stress risers or fracture points.
- Can fabricate components at speeds up to and many times over 120 parts/min. Screw machining and other processes may manufacture components at speeds of 10-40 parts/min.
- Produce near net shapes for screw machining or grinding. Your designs which can notcannot be directly cold formed or those requiring very precise tolerances (better than +/- .005) cost can be reduced by forming a blank which is very close to the final component. Secondary operations can be performed to achieve the final product. Scrap is reduced and secondary operation time is kept to a minimum.
Each of the five items alone or in combination reduce your component’s final cost.
If you would like to submit a drawing for a Cold Forming valuation, we can accept most neutral formats. For 2D drawings, we can read dwg, dxf, wmf, and emf. For 3D formats we can read iges, step, stl, acis, and all parasolid formats. If you are unfamiliar with any of these formats, or prefer another, let us know.
