Implementation of Continuous Improvement to Increase the Efficiency of the Production Process through Press Dies Design

In the manufacturing industry, there are companies that operate in the metal forming sector. Many products are produced by the metal forming process, one of which is the packaging box lock hook. The key hook is a component part of the packaging box which functions as a hook so that the packaging box can be closed and locked. In the production of key hooks there is waste, namely over processing, which reduces the efficiency of production time. To reduce this problem, improvement efforts were made by implementing continuous improvement using the DMAIC method. Continuous improvement steps are carried out by direct observation in the field to find problems. After that, measurements and analysis are carried out to determine improvements that will be implemented. Then the improvement stage was carried out as an implementation of continuous improvement. Continuous improvement resulted in a press dies design for the key hook piercing process. By designing new press dies, production time efficiency will be achieved. After carrying out Continuous Improvement, it resulted in an increase in the efficiency of the number of processes from 6 processes to 5 processes and the total production time in 1 cycle from 13.3 hours to 11.4 hours or 1.9 hours faster or an increase in efficiency of 13.3 % of the total time before Continuous Improvement. And 50% increase in sub piercing process.
