Dmaic Process

When a firm sustains profits that exceed the average for its industry, the firm is said to possess a competitive advantage over its rivals. The goal of much of business strategy is to achieve a sustainable competitive advantage. Strategy constitutes the process through which such actions are developed and implemented, and as a result it is critical to the relative success of an organization in its business context over time. To achieve them, G Plast necessary to develop an accurate process model for describing the process. Injection moulding conditions such as melt temperature, mould temperature and injection time are important parameters in the injection moulding process. Moreover, the aim is to keep cost at minimal with a high quality. The case mentioned here is a process level six sigma, applied in the component manufacturing area. It is a business system with many statistical aspects and it is an operational system that speeds up improvement by getting the right projects conducted in the right way. With the structured methodology of the define, measure, analyze, improve and control approach, and design of experiment, they were able to optimize the process parameters and produce consistent good quality components.

Fitment carried out at TATA motors failed due to center distance variation by 0.9mm in the Indica inner case. As the whole cluster is assembled in Continental (SVDO) and despatched to TATA motors and due to this problem the whole cluster itself got rejected. G Plast studied the performance of a particular process thoroughly and compared it with the expected level of performance but the data is not useful due to the process is not centered even though the dimensions observed lies within the specification limits. The data’s taken after 2-hours shows us that it may arrive within specification limit but it is a one sided process and not a centered one for better stability and capability. A typical rule presently is the rejection level affects...
