PRODUCTIVITY IMPROVEMENT ON FILTER DRIER COMPONENT BY REDUCING CAP ASSEMBLY CYCLE TIME

Mechanical Engineerig

The manufacturing of filter drier Component involves the following processes: viz; Cleaning of components (Washing), Brazing the Filter Cup with Bronze Ring (Furnace), Core assembly, Plasma welding, Leak Testing, Cap assembly. The overall output of the Filter Drier component is 820 numbers per shift. Due to the market demand customer requirement increased to 1200 numbers per day. But company unable to achieve the customer requirement in present condition. Cycle time study done for each process of the Filter Drier manufacturing and found that more time (33 Seconds) taking process is the Cap assembly. Then further cap assembly activities were studied the activities are applying rust preventive oil, cap insert, clamp the component in the fixture, apply the torque in one side, rotate the fixture by 180 degrees, apply the torque at another side. In the above said activities there is some unwanted activities present in the cap assembly. The activities are clamping the filter in the fixture, rotate the fixture, applying the Torque in another side and unclamp the component from the fixture. These activities are eliminated by implementing new fixture and designed a new fixture to apply torque on both sides of the component in a single setting also there is no need of clamping and unclamping
