OBJETIVE: Identify improvements to reduce the gab in the productivity to 14% (i.e. from 9 to 10 bags/min).
IMPACT: This improvement would give to the company an estimate of $0.25M per year.
SCOPE: In the packaging line nº1 focus on 3/4 types of electrode diameters. It represents 80% of total production.
CONTEXT: This project is developed in a Peruvian manufacture company of electrodes for welding. Currently, there are four packaging lines with 100% of utilization on pick seasonal demands. There is a gab of 22.6% in the productivity with repect to the ideal value.
