What is Die Cutting?
Die cutting is the process of cutting a sheet or roll of stock material into a smaller and more useful form using tooling called a die. It dates back to the mid-19th century to modernize the shoemaking industry. This manufacturing process has evolved to meet increasing demand and create more complex designs.
The stages of a die cutting process are feeding, cutting, and stripping, which is common to all die cutting methods.
Flatbed die cutting machines utilize an assembly to cut the stock material through a press. These machines are capable of operating at high pressures, giving a more precise and deeper cut.
The press of a flatbed die cutting machine consists of a die board and a lower plate. The die board contains the cutting and punching tools, and a rubber ejection strip. The lower plate supports the stock material during cutting.
The die board has several configurations depending on the cutting steps involved: simple, compound, progressive and combination dies.
Rotary die cutting machines operate in continuous production mode at a constant speed and lower pressures. It utilizes two cylinders: a cylindrical die and an anvil rotating in opposite directions to cut the moving web.
The two types of rotary dies are flexible die and solid die.
Die cutting machines are also capable of making kiss cuts, scores, and perforated holes, which define the characteristics of the part.
There are part design considerations for the die cutting process to maximize reliability during handling. The four basic elements of die cut parts (blanks, scores, holes, and tabs) are considered.
