Abstract—This research aims to present guidelines for improving the production process for Bakelite powder plastic molding of four major types of cookware handles, including extra-large handle, large handle, flat handle, and pan handle. Reportedly, these four products are manufactured based on similar processes, consisting of powder molding, burr trimming, and filing. This research relies on several techniques and studies, particularly in collecting recent production data and making theoretical analysis to seek causes of problems. Using a fishbone diagram, the obtained data can be analyzed and developed based on the Eliminate Combine Rearrange Simplify (ECRS) principle, which helps in the development of design and facilitates the three manufacturing processes. Aside from time efficiency in production, this can also lead to the increase of productivity per day. Besides, the researcher uses the Predetermined Time System (PTS) for an advanced assessment of time to seek accurate production rates following the design process. As the design process is completed and the PTS has been applied, daily production of extra-large handle, large handle, flat handle, and pan handle is estimated to increase from 734, 925, 811, and 517 units per day to 777, 935, 877, and 552 units per day, considered the increase of 5.8%, 1.1%, 8.0%, and 6.7%, respectively.
