Progressive Die Stamping vs. Transfer Press Stamping
Progressive die and transfer press stamping are similar operations that offer distinct advantages and disadvantages based on the specific demands of an application.
Progressive Die Stamping
In this process, a metal strip moves through a series of unique stamping stations to perform separate functions within a single machine. Each station alters the metal strip before it continues to the next station. The stock strip progressively takes on the desired shape and dimensions as it moves through the workstations. Precision throughout the entire operation is essential for total accuracy and effectiveness. Because all the parts are attached on one strip, this strip must be accurately positioned or all parts could be ruined.
Industries that benefit from progressive metal stamping include electronics, food and beverage, medical, appliances, military, automotive, and more. The process offers the following advantages for these industries:
- Improved Production Speeds
- Long Run Lengths
- Less Scrap Material
- Broader Design Freedom
- Increased Production Capacity
- Shorter Setup Times
- Higher Repeatability Rates
- Lower Production Costs
- Decreased Labor Costs
- Tight Tolerances
Transfer Press Stamping
This technique is the preferred stamping choice for large parts and applications with complex designs. In transfer press stamping, one press can operate multiple tools. Each part gets removed from the metal strip in the first station, allowing it to be freely shaped and transferred by each transfer die until completion.
Previously, these procedures required multiple manual transfers and presses, but automation has streamlined the transfer process into a single operation. Transfer press stations can produce the following:
- Threading
- Ribs
- Knurls
- Cutouts
- Pierced Holes
Transfer die stamping is ideal for low-volume production runs, offering better versatility and affordability when compared to progressive die stamping. Transfer die stamping can create complex geometries, intricate parts, and larger components with increased cost efficiency due to its lower tooling costs and reduction of scrap waste.
Industries enjoying the benefits of transfer die stamping include agriculture, automotive, electronic, medical, transportation, and more.
