| Popis: | Sand casting is a process of producing complex shape castings which cannot produce by other processes. Production of defect free casting is a challenging task in a foundry. The quality of component produced by sand casting is affected due to uncontrollable process parameters. Until controlling such parameters, it is difficult to achieve defect free casting. Keeping this in mind, a study is carried out in a jobbing foundry in South Tamil Nadu. From the six months rejection data, it is identified that the Pump Mounting Flange is mostly rejected due to cold metal defect. In order to overcome the cold metal defect the process parameters mold hardness, moisture, time and temperature of pouring are investigated using the Taguchi approach the optimized values are arrived. The regression analysis confirmed that the optimized values are acceptable. The values are recommended to foundry for the production process. By six sigma methodology (DMAIC), the quality tools Data Chart and Histogram are used to select defected casting. From the Cause and effect diagram the root cause of the cold metal defect is identified. |
