Improving Painting Process to Control Variable Dry Film Thickness (DFT) For Front Axle Beam

Abstract

After the front axle beam is manufactured, there is a need for proper coating of paint in order to prevent rust
and corrosion. The paint coating is provided for maximizing the life of axle beam. Dip paint process efficiency is
dependent on paint consumption and dry film thickness. This paper represents the influence of temperature, controlling
paint ethanol mixture with respect to DFT obtained. In this processing of axle beam after forging takes place. Grinding,
shot blasting, straightening, sizing, crack removal and thereafter painting operation is done. There are coming numerous
paint defects and flaws after a certain span of time. So in order to reduce them and enhance the process capability, we
are implementing six sigma - DMAIC methodology. It is the aim of the author to address this issue by the use of
discussion and case studies and to provide some useful guidelines and insights when performing capability analysis
using Minitab.
