Hand tools sector: Fixtureless assembly in hand tool manufacturing sector

INFAR, a hand tool manufacturer located in Taiwan, produces almost 25M wrenches, ratchet handles, and various types of accessories per year. 

During manufacturing process, the most critical procedure is part assembly for completing an entire hand tool no matter a wrench or a ratchet handle.  

At the moment, most assembly tasks are performed manually by human workers. They prepare components required for assembling a hand tool, apply glue on the inner perimeter of the ratchet by hand, start assembling components inside the ratchet and, finally, complete the assembly process in order to have the finished product. 

HARTU technologies will facilitate automation, which is a big challenge due to the need for hand tool specific fixtures, dexterity and accurate motion planning.
