How to Design Out Wire Form Costs With Natural Flow
Flattening metal wire is often called crushing or planishing. This process is the result of pressure applied by use of a press. The press comes down, makes contact with the metal, then the material flows to the side. When designing a part, it is less expensive to allow for the natural flow of the material. This savings is achieved in two ways…
- The cost of the tool. Custom Flattening tools can be expensive
- The cost of an operation
If the width of a flattened part needs to be exact, it needs to be trimmed, which is created by a trim die. The operation of trimming can cause undue costs as well because it is another operation. If an exact dimension is integral to your design, consider asking for a tandem operation. In a tandem operation, the two parts are processed simultaneously. One part is flattened in the flattening station; a second part is flattened in the trim station. One stroke = 1 part. This is one way that Argo
Products is able to save its customers so much money.
There are a few rules of thumb:
- Maximum wire diameter that can be flattened by Argo Products is 1.25” diameter, C1008 CF wire
- The flattened width is a function of the thickness of the desired flattened area
- Minimum thickness is 30% of the wire diameter
- Both the flat and the width feature dimensions cannot be specified. Dimension one as critical, let the other float.
