Track: Automation and Control

Abstract

During a machines lifespan, it reaches a point where it no longer performs as it used to in its early age. When this happens, one of the options to consider is the procurement of a new machine. However unavailability of funds may always hinder this process leading to the next best solution, redesign (design modification). ZXY is a metal and plastic packaging company situated in Zimbabwe. One of their production processes produces crown caps for carbonated drinks. Two machines are available for this process, the SACMI Press machine and the Callahan press. This paper involves the redesign of a Callahan punch press machine for crown caps at ZXY and the factors leading to the design modification .It looks at the design of the punching tool, which is the punch and the die, the automation of the guard. After the redesign, the implementation of a proactive maintenance strategy is then looked at for the redesigned machine.
