- Implementation of TPM and 6S Lean in SonafiPublication . Nadaradjane, Sivasangarane; Ramos, Sandra Cristina de FariaIn today’s industrial scenario huge losses/wastage occur in the manufacturing shop floor. This waste is due to operators, maintenance personal, process, tooling problems and non-availability of components in time etc. Other forms of waste includes idle machines, idle manpower, break down machine, rejected parts etc are all examples of waste. The quality related waste are of significant importance as they matter the company in terms of time, material and the hard earned reputation of the company. There are also other invisible wastes like operating the machines below the rated speed, startup loss, break down of the machines and bottle necks in process. Zero oriented concepts such as zero tolerance for waste, defects, break down and zero accidents are becoming a pre-requisite in the manufacturing and assembly industry. A fundamental component of world-class manufacturing is that of the Total Productive Maintenance (TPM), which has been recognized as one of the significant operation strategy to regain the production losses due to equipment inefficiency. TPM is the methodology that aims to increase both availability of the existing equipment hence reducing the need for the further capital investment. The automotive sector constitutes one of the most demanding activities in the global market, since it requires a constant increase in productivity, both in the automobile industry as well as in the companies whose manufacture its components. This sector is currently set within an economic framework where there is a relentless search for costs reduction and an increase in productivity with minimal investment. In order to meet these requirements, companies have sought to optimise their products and processes to ensure higher profits. The main aim is to develop a framework with the capability of assessing the impact of implementing TPM in a company which supplies die-casting products to the automotive sector. The major action was taken in the autonomous and curative maintenance. Due to the undertaken improvements, there was a 2% increase in OEE (Overall Equipment Effectiveness) on line AA3. Along with TPM, 6S Lean is also implemented that is one of the main points of the new standard for automotive industry IATF 16949:2016.
