Manufacturing Manufacturing At the 155,00-square-foot Cloyes manufacturing plant in Paris, Arkansas, USA, highly-skilled employees manufacture machined powertrain gears, sprockets, and idler assemblies for automotive original equipment manufacturers, the automotive aftermarket, marine, and high-performance applications. The plant’s key processes include machining, hobbing and shaping, heat treatment, and finishing, and the plant is also home to a quality and metrology laboratory that supports both manufacturing and engineering product development. Broaching is the process where the Internal Diameter (ID) of the part is brought to final size. Cloyes has thousands of attribute gauges to inspect many part characteristics on the shop floor where the parts are being processed. Cloyes’ state-of-the-art metrology lab includes inspection equipment such as CMM, Gleason Gear analyzer, and hardness tester. Cloyes has many conventional hobbing machines and gear shaving machines. Cloyes utilizes bar acmes to efficiently turn sprocket and gear blanks from steel bar. Cloyes utilizes CNC turning laiths for precision turning to produce high performance sprocket and gear blanks. Cloyes utilizes shaping machines to produce high quality splines and sprocket teeth. Cloyes utilizes CNC milling to produce a wide range of bolt patterns, counterbalances, and weight reduction features. Cloyes utilizes keyway broaching to cut the keyways in many of the sprockets we produce. Cloyes has two induction heat treat machines and one tempering furnace – this is a competitive advantage compared to many other manufacturing facilities that outsource heat treating while we do this work in-house. All Cloyes products must go through a final inspection audit prior to being released to finished goods.
