Application of Lean Techniques in a Discrete Manufacturing EnvironmentThis article describes how Lean manufacturing techniques were applied to a mature product, in a mature industry; it follows a previous article "Application of Finite Capacity Techniques in an ERP Environment" by the same author, published in 'Control', July/August 2002.
Capacitors have been manufactured for around 100 years, and very little has changed to the design. Basically the capacitor is a series of 'elements'encased in a steel box and impregnated with special oil as in Figure 1. The elements are wound from reels of polythene film and aluminium foil between 5 and 16 micron thick. The manufacturing process is shown in Figure 2.
