This research paper explores the status and imminent factors for evaluating the feasibility of implementing Six Sigma in medium scale Indian automotive industry. The research methodology, designed using quantitative approach, reports 30 medium scale automobile enterprises started implementing Six Sigma during survey range of 2009-2010 from west India. The research finding shows diversified practices of traditional quality initiatives, e.g. ISO 9000, total quality management, Kaizen, etc. over Six Sigma as well as various rationale of poor implementation of Six Sigma in manufacturing sectors of Indian automotive industry. Comparative data analysis of the research will cumulatively elaborate various parameters, e.g. Six Sigma training programmes, initiatives from top management, methodologies of Six Sigma in practice, various performance metrics of Six Sigma projects, quality tools in practice, as well as various reasons for not implementing Six Sigma within small and medium enterprise. The results obtained are the insight of implementing Six Sigma in medium scale Indian automotive sector.

Indian automotive ancillary units are one of the swift growing within the small and mid-sized group of industries which are influential contributors to the complete production of auto components. With the ascent in interrogation of growing customers and presuming for resplendent quality of their product, some of giant Indian organizations are inspiring their suppliers to employ Six Sigma in order to improve the quality of their process and products for embellishing competitive advantage. This paper focus on a case of provoked mid-sized auto ancillary unit consisting of 350-400 employee and employed Six Sigma (SS) methodologies to elevate towards the dream of SS quality level. The methodology is executed on one of product assembly for trimming down defects level which are critical to customers and its implementation has had a significant financial hit on the bottom-line of the enterprise.

The present work focuses on Experimental investigation of heat transfer and friction factor characteristics of horizontal circular pipe using internal threads of pitch 100mm, 120mm and 160mm with air as the working fluid. The transitional flow regime is selected for this study with the Reynolds number range 7,000 to 14,000. The horizontal aluminum pipe was subjected to constant and uniform heat flux. The experimental data obtained were compared with those obtained from plain Horizontal pipe. The effects of internal threads of varying depth on heat transfer and friction factor were presented. Based on the same pumping power consumption, the pipe with internal threads possesses the highest performance factors for turbulent flow. The heat transfer coefficient enhancement for internal threads is higher than that for plain pipe for a given Reynolds number. The use of internal threads improved the performance of horizontal circular pipe.

Composites or composite materials are engineered materials that consist of two or more constituent materials with wide discrepancies in their physical, chemical, and mechanical properties. The characteristic properties of these composite are as a result of the individual properties of their constituent parts and their respective volume fractions and arrangements in the material system. Depending on the intended application, composites can be designed to satisfy specific geometrical, structural, mechanical, chemical, and sometimes aesthetic requirements. Areas of application of these synthetic materials includes construction such as in buildings and bridges, automotive industry such as in car bodies, aeronautic, naval (e.g., ships and boats), and in the biomedical fields. Therefore, the main purpose of this paper is to introduce composite materials, epoxy resins their additives, fillers and discuss their current and potential use in coatings, electronic materials, adhesives, and matrices for fiber reinforced composites because of their outstanding mechanical properties, high adhesion strength, good heat resistance, and high electrical resistance.
