Compound die stamping and progressive die stamping are two of the most popular metal stamping methods that find application in various industries. Both methods are suitable for different application depending on tolerances, designs, and production sizes of the required metal part.
Look at the following metal stamping procedures that are routinely utilised and notice the distinctions between each of these techniques.
Progressive Die Stamping
Progressive die stamping is ideal for mass-production of highly precise metal stamped parts. Here the metal sheet goes through a series of metal stamping work stations placed throughout the stamping press.
The workpiece stays linked to the base strip during the whole process; the last phase is the separation of the individual finished components from the base metal strip, which takes place after the workpiece has been completed.
The following are the primary benefits of progressive die stamping:
- High-volume manufacture of tiny components with strict tolerances in a short period
- Setup time is minimal.
- Labour expenses are being reduced.
- Minimal scrap
- Reduced Time and money
In brief, progressive die stamping can produce components with complicated geometries in a short amount of time and at a low cost while maintaining high levels of reproducibility. It is also unsuitable for components that need extensive deep sketching. However,progressive die stamping requires permanent steel tooling.
The most common choice of base metal for progressive dies are Steel, aluminium, copper, stainless steel, and brass are all typical materials found in construction. In some specific cases, depending on the application manufacturers use noble metals, titanium, and superalloy Inconel.
Compound Die Stamping
Compound die company stamping is used to create basic flat items, such as washers, using a single die. A strip of metal is passed through the compound die; however, unlike progressive or transfer die stamping, compound stamping tooling makes several cuts, punches, and bends in a single stroke rather than many strokes as in progressive or transfer die stamping. Therefore, compound die stamping proves to be a cost-effective option for producing medium- to high-volume metal parts. .
Compound die stamping is characterised by rapid production; nevertheless, the pace of production depends on the part’s size and design.
Advantages of using compound die are that it:
- Produces basic components at an optimum speed and cost..
- Ensures reproducibility for single-die applications
- Saves operational and maintenance cost. .
Compound stamping and progressive stamping both have significant advantages in terms of speed. Since prpgressive dies use a multi-stroke mechanism, it is best suited for precision stamping.
The following are the most significant differences between compound die and progressive die stamping:
- Compound tooling is less expensive to produce and takes less time to construct than progressive tooling
- Compound stamping is ideal for simple flatter parts while progressive stamping is best for high-speed, high precision stampings for small and medium sized components.
