The progressive die is one of the most common, fastest methods accessible for producing piece parts. Unlike line or transfer dies, progressive dies tie the parts together by way of percentage of the first strip or coil, which is sometimes called a strip carrier. Different types of parts require different carrier designs.
Progressive dies can produce only seven or eight parts for each minute or as many as 1,500 parts each and every minute. Unlike transfer or line dies, all necessary stations are attached with an individual common die set. These stations are timed and sequenced so the piece part might be fed ahead a consistent given distance the progression or pitch. Many parts might be tied together allowing many parts to get made with each single press stroke.
Progressive dies normally are coil-fed, and if they secure the proper sensing system, they frequently can run unattended. It's not necessarily uncommon to get a single press operator to own two or three progressive dies. The coil material typically is pushed over the die; however, systems that will pull and push the coil material over the die are offered. Progressive dies usually require using a coil feeder and stock straightener.
Progressive die advantages are:
• They are able to make a great number of parts right away.
• Sometimes they can run unattended.
• They might need one press.
Progressive die disadvantages are:
• They often are more expensive than line or transfer dies.
• Sometimes they require precision alignment and setup procedures.
• They require a coil feeder system.
• Needed a-ended press to permit to the metal to feed to the die.
• Destruction of a single station requires removing the entire die set.
• They frequently tend to be heavier than single-station line dies.
