It might be tough to identify the optimal production process for your project because there are so many options. This post intends to show you the advantages and methods of one of these productions known as Progressive die. Compound die, progressive die, and transferable die are all ways for stamping metal components for various uses.
Companies that see each stamping process can rapidly identify the proper partner to carry out the work for their project since each market has various end uses that have different demand tolerance, designs, and production volumes.
What is Progressive Die Stamping?
Progressive die stamping is a metal forming method commonly utilized in automotive, electronics, and appliances to make parts. Progressive die stamping comprises many workstations, each conducting one or more operations on the component. The stock strip transports the part on each station, and the component is cut from the strip in the final operation.
- The die is inserted in the stamping press to begin the procedure.
- When the stamping press moves up, the die opens, and when the stamping press travels down, the die shuts. The metal travels through the die while it is open, precisely fed into the die with each press stroke.
- When the die shuts, it begins working on the metal, involving coining, bending, cutting, embossing, and other operations. The final item is removed from the die after the metal has passed through each station.
- The size, complexity, and volume of manufacturing influence the process, whether a part gets produced in a progressive die or a transferred die. Progressive die stamping is employed to create many factors while keeping prices down. The most excellent accuracy and durability requirements must be satisfied.
- To sustain the high shock loading, maintain the required sharp cutting edge, and resist the abrasive pressures, dies are often manufactured of tool steel.
- The price is dictated by the number of features, which determines the tooling required. To keep the cost of tooling down, it’s best to make the features as basic as possible. Closely spaced elements present an issue since there may not be enough clearance for the punch, resulting in another station. Narrow cuts and protrusions might be hazardous as well.
- It’s crucial to think about project timescales while determining which strategy is ideal when evaluating the demands of your project. While, for example, stage tooling has a slower fabrication speed, progressive die and transfer press tooling have faster production speeds.
- More complicated designs and more acceptable tolerances are possible with progressive die stamping. This makes the method ideal for high-volume manufacturing of tiny components but not necessarily for deep-drawing goods.
What Factors Contribute to Achieving the Perfect Part Quality?
- Blank Position
- Blank Boundary
- Stretch-Web Deformation
The Importance of Pilots:
Pilots are crucial in progressive die stamping because they place the strip in the correct location and control it. They’re also necessary for precise sheet alignment in transfer dies during tool closing and drawing operations.
These pilots are usually conical or bullet-shaped.
What are the Benefits of Progressive Stamping?
Progressive Stamping Dies machines work at exceptionally high rates of hundreds of components per minute with low downtime, thanks to a continuous material input. This allows for faster cycle times, shorter lead times, and more production capacity.
An advanced stamper’s dies are firmly tooled. They can sustain high-volume progressive stamping operations without deteriorating, ensuring that the components produced are of good quality. This process’s excellent part-to-part repeatability assures consistent quality throughout the production run.
Traditional short-run stamping methods require many setups, tool changes, and die changes to manufacturing complicated components; progressive stamping requires one setup to generate fundamental parts.
Due to electronic monitoring built-in specialized tooling, one person may supervise numerous machines that run unsupervised.
Long production runs are possible because of the same continuous material input that allows for progressive stamping dies. More manufacturing time between material changes translates to more finished components in less time.
Low Part Cost:
These elements work together to lower the per-part cost of progressive stamping components.
Scrap metal is unavoidable in every production process, but its improved tool design is minimized by progressive stamping.
It’s crucial to consider cost when deciding between progressive die stamping and traditional metal stamping processes like stage tooling and transfer press tooling. Stage tooling offers an affordable setup but the most expensive per-piece cost. Compared to stage tooling, progressive die and transfer press tooling have higher setup costs but reduced per-piece prices.
