ABSTRACT

A Manufacturing defects or errors are always the key concern of any manufacturing and pump manufacturing industry. The Lean management is dedicated to the improvement of productivity, efficiency, quality and in general of business. Kaizen, 5S and Six-sigma remain the foundation of lean Six-sigma Management System. Those tools for cleaning, sorting, organizing and providing the necessary groundwork for improvement and preventing the small errors and problems of machine, man and management as well as reduction of rework and variation with better process control. Now a day, all the Pump manufacturing industry are moving the direction of Errors free production with higher safety provision. After applying Lean management, we can achieve better result as per production in cost and good working environment with less human errors and cycle time reduction. Lean methodology also increases better SHE (safety, health and environment) standard of any organizations. Sis-sigma Methodology is basically used to reduction in variation, rework and give better Process Control. In pump industry, Pump defects can come from any of the unite operation and from the pump press. The Turning and Grinding operations often the source of defect. Such as pressure drop, mechanical issue, noise, less discharge, leakage are among the most mutual problems during pump testing.

INTRODUCTION

VBC Hydraulics established in 1995. VBC taking full advantage of its forward-looking management policies and by incorporating unique R&D activities has made constant effort on development and Innovation. as a result, VBC Hydraulics currently produce a wide variety of outstanding Hydraulic Gear pumps for Agriculture & constructionmachinery, industrial hydraulic power pack, rubber and plastic molding machinery, material handling equipment and so many other industrial applications with global standard. The corporation, which relies on its design & patents, advance technology and management, always keep improving to be better. Nowadays, ―high number of Industrial Accidents Occurs due to human Error. There some methods to prevent such an industrial accident and the most effective method is to develop the human behaviour by giving particular training for the work, conducting behavioural based study to reduce the accident rates and to improve the safe environment in industry. From the various studies, we can clearly say that, one of the causes for initiation of industrial accident is poor management system such as policy, safety systems etc. For improving the safety culture and behaviour of the employee, industry needs to provide training, education, meeting, review etc. For this purpose, the industry is in the position to spend money for the following aspects; Training, Education meeting. Communication also plays a major role in accident because the performance of communication from top level to low level management is very poor. This paper deals with potential causes of accident and rework and productivity improvement with better process‖ yield.

LITERATURE REVIEW

Dr. JA doshi et. Al [1]. To Minimization of defect and rework is an important factor ensuring the quality of product. It indicates eliminating non value-added activity like rework, man hour spent on rework and taking effective measures will enhance the net profit, saves time and improve overall quality ofproduct. higher lead time, paper work and good employeemorale.

It should be placed on reduction in throughput time, addition of work station to meet the takt time and elimination of unnecessary activities. Chakravorty, s.et. al [4]. ―The tools of the LSS Practice enriched the efforts towards waste reduction and rework reduction.

The beyond review indicates that factors such as communication between the top management and its employee, clear strategy, the need of a personnel who can champion the implementation of kaizen in a company, having good knowledge and provide employee with certain level of empowerment are important to ensure a successful Kaizen implementation.

METHODOLOGY& ANALYSIS

Kaizen is Japanese Word Which also Known as Continuous improvement by every day, everybody, everywhere. Kaizen is most important for step by step small improvement and get better result in production line [15]. Kaizen is focused on productivity, reducing variation.

Currenr Data Analysis

 Check current process yield and DPMO

Total Pump manufactured 4093, out of which 216 pumps are reprocessed.

 Yield of the process

Y= Actual Output / Expected output* 100

Y= 4093/ 3877*100 =10.55%

 DPMO (Defects per million opportunities)

= No. of Defects*(10)6/((No. of unit) * (No.of Opportunity))

= 216*106/(4093*6)

 Current DPMO: - 8795.5
