Transfer Die Stamping compare with progressive die stamping

A method of metal forming frequently used for the production of components for the appliance, electronics and automotive industries, progressive die stamping includes the use of various stations in one machine; each of these stations performs at least one operation on the part being produced. Attached to a metal strip, the portion passes from one station to another automatically, or “progresses,” until it is full and separated from the strip during the last procedure.

Instead of passing through a device while connected to a metal strip, as with the stamping of the transfer die, during the first procedure a portion is separated from the strip so that it can be moved from one station to the next to finish its development.

Progressive Die Stamping Key Features and Benefits

The movement must be done carefully and meticulously to ensure the accuracy of the finished product in order to advance the metal strip from each station. Because the part is attached to a metal strip throughout its formation, if the strip is off even by a small fraction of an inch, the entire process will be ruined. Conical-shaped pilots insert the strip into pre-pierced holes to ensure alignment accuracy as part progresses.

Progressive die stamping provides some distinctive advantages, including the high velocity with which the goods can be produced; the low labor expenses involved, as only one operator has to oversee the machine; and the minimal quantity of scrap left behind due to the high design of progressive die machines. And, as stated, instead of performing several setups — as with traditional techniques of stamping — progressive die stamping needs one setup only.

The dies can withstand large amounts of runs without degrading during progressive die stamping, allowing for high repeatability. Because the material is continuously fed into the machine, it is possible to complete long production runs, producing more finished parts in less time. All of these benefits lead to lower cost per share.

Transfer Die Stamping Key Features and Benefits 

Transfer die stamping operates various instruments using one press. Removed from its metal strip to allow it to be moved freely, each die forms a part until it is full. In the past, numerous presses and hand transfer were needed for these processes. The transfer process automation streamlines the procedure into a single press.

Transfer die stamping needs process alignment and low interference from the mechanisms that transfer the portion from station to station. Automation handles these requirements effectively, enabling mass manufacturing.

Also, the same sectors that use progressive die stamping use transfer die stamping; the better choice merely relies on the particular portion at hand. Typically, stamping transfer die is used for big parts such as frames, pipe apps, shells, and structural elements.

How to choose from Progressive Stamping and Transfer Stamping

When selecting to use progressive die stamping or transfer die stamping, consideration must be given to part intricacy, size and amount.

Progressive die stamping is perfect for producing a large number of tiny components in a brief moment. The method enables multiple sections to be formed and cut simultaneously, saving both cost and time of manufacturing. Progressive die stamping needs accurate execution and elevated die durability to guarantee effective completion of the project, so it is often essential to invest in continuous tool steel die sets.

More cost-effective than gradual die stamping, more versatility is provided by the transfer die stamping. If a part needs trait such as knurls, ribs, threading, or cutouts, the transfer die stamping can be incorporated into the procedure in order to minimize additional costs.

The correct technique of stamping for your work will rely on the application’s distinctive demands.
