Since liberalization of the economy established in 1994, India faces strong international competition. Thus, growth and
diversification of its industry are increasingly characterized by a shift from simple to technically complex products.
Many enterprises aim at high value-addition. Modernization and automation of production processes increase productivity and reduce unit cost.
This is particularly true for the engineering industries (metal and plastics processing ventures) as well as small and medium-scale
enterprises (SME). They manufacture tools and molds or use them for producing parts, components, systems, and final products,
often as sub-contractors of large enterprises.
In recent years the quality of their products and the efficiency of their production processes augmented considerably . Nevertheless,
many SME still face constraints. They are related to rapid changes of the market and accelerated technological progress.
