Six Sigma application for quality improvement of the hot press in process

Six Sigma is a systematic improvement method, a management approach designed to continuously improve corporate business processes and achieve customer requirement.This paper presents a case study conducted at a cell phone manufacturing company that intended to use the DMAIC method to carry out a structured approach to Six Sigma projects with fewer defective units generated by the cell phone hot press in process.In this process, Boss cracking and torque force failure led to high scrap costs and line downtime, which ultimately affected the supply of the pc850q assembly line.To this end, the Six Sigma approach was applied starting with the problem being defined, measured, and exhaustively analyzed to determine the root cause: poor injection molding structure, metal insert not perpendicular to the hole, improperly leather baton holder set molding machine parameters, and core/cavity dimension variation.

A series of improvement measures addressing these factors increased the quality level of the process by improving the mold design to increase venting, optimizing the product structure to add the guide chamfer, and developing a standardized molding parameter setup procedure.Methods to maintain process control were also identified and implemented.The use of several quality tools and the use of Six Sigma methods also made the process more consistent.
