Developed as a way of fastening paper together for important documents at the French royal court the stapler has since evolved to be used in a number of industries, including medical surgery and furniture manufacture. Although specialty and novelty versions of the stapler are manufactured the process of producing a stapler remains similar to that of the simple office and school stapler.

With the exact origin of the stapler unknown many researchers agree the first stapler's were used by members of the French court in the 18th century with wire rivets inserted into pieces of paper before being manually bent into place, Diao reports. In the mid 19th century the first attempts to create a stapler capable of bending the staple after it passed through the papers were made and resulted in a number of companies creating similar products throughout the century. By the 20th century staplers could be found in most offices, schools and homes as a simple way of combining a group of papers together in a safe and sturdy way.
The first step in manufacturing a stapler is to create the parts of the machine on their own before they are combined to create the finished product, according to Made How. Each stapler is made up of a base, head, springs, rivets, pin and a plastic cover that are made using punch and die technology and other technologies in a mass production factory. The process follows a detailed design plan of the size and shape of each part to be produced.
Usually the production of a stapler begins with the fabrication of two springs, a leaf and a coil spring, How Made reports. Both the coil and leaf springs are produced under high temperatures that allow them to be tightly wound and curled to produce the movement required for them to work well. A metal base and head are produced using punch and die technology that punches down at high speed and pressure on sheet metal. The piece of metal punched out of the sheet is produced to the specifications of the die and is then heated before being folded to produce the shape of the base and head of the stapler.
Once the pieces of the stapler have been produced they must be assembled to produce the finished product; to complete this task each stapler is held together with metal rivets that are inserted into the parts with an orbital riveter, Made How reports. To allow the metal head and base to pivot a pin is placed between the parts to hold them in place and allow the movement of the stapler to be performed. The springs are inserted to allow the stapler to spring up and down and the second spring moves the staples through the magazine and holds them in place. Once assembled the stapler is sprayed with paint to make sure it has an attractive appearance.
