This paper presents how to design a staple gun and verify its data through simulation. The staple gun was estimated and
analyzed using 'ANSYS' software and the results were compared with those obtained through experiments. In this
research, a supporting position for the spring inside the staple gun was damaged after hundreds of loads, and there was
no data about the impact force when staples were shot into the targets. Therefore, a prototype test system is developed to
validate the data through simulation. In this case, the results are quite close to each other before they can be used to help
the manufacturer to improve its structure. This prototype test system is completed through PC-based automation software.
The simulation model was modified to develop the next new products for saving costs and time. Because the impact
force, coming out from the staple gun is pretty large, it should be restricted within a certain limit to keep the user safe.
