Plastic Injection molding is a manufacturing process for producing parts from both thermoplastic and thermosetting plastic materials. Material is fed into a heated barrel, mixed, and forced into a mold cavity where it cools and hardens to the configuration of the mold cavity. After an industrial designer or an engineer designs a product, usually, molds are made by a mold maker (or toolmaker) from metal, usually either steel or aluminium, and precision-machined to form the features of the desired part. Injection molding is widely used for manufacturing a variety of parts, from the smallest component to entire body panels of cars. It is also used to create many things such as wire spools, packaging, bottle caps, automotive dashboards, pocket combs, and most other plastic products available today. Injection molding is the most common method of part manufacturing. It is ideal for producing high volumes of the same object. Some advantages of injection molding are high production rates, repeatable high tolerances, the ability to use a wide range of materials, low labour cost, minimal scrap losses, and little need to finish parts after molding. India automotive industry is expected to grow in another ten years. The Indian automotive industry is growing at a very high rate with sales of more than one million passenger vehicles per annum. The overall growth rate is 10-15 per cent annually. The entire car market was likely to witness a fair amount of churning in the coming years. This will definitely be a driving force for a high demand of auto components. India is the worlds second largest manufacturer of two-wheelers, fifth largest manufacturers of commercial vehicles as well as largest manufacturer of tractors. It is the fourth largest passenger car market in Asia and home to the largest motorcycle manufacturer. Coming to the Auto-component sector, the total market size of the auto-components industry is estimated at over Rs 700 billion. The industry estimates that the Indian components industry will grow to over Rs 950 billion by 2010. The overall investment in the components industry is estimated at Rs 288 billion. Indigenous firms like Bharat Forge, Sundaram Fasteners, Minda Industries and Gabrial India Ltd. are in the limelight. There is a boom in the auto components segment because of strong demand and robust economy. Also, the industry has strong forward and backward linkages with almost every other engineering segment. The component production range includes engine parts 31%, drive transmission and steering parts 19%, suspension and braking parts 12%, electrical parts 10%, equipments 12%, body and chassis 9% and others 7%. The auto component suppliers are emerging as systems suppliers with capacity to design and develop critical parts. The Indian automobile components industry has, no doubt, significant cost advantages, primarily due to lower labour cost. There is a very wide scope and good market potential of products manufactured in this sector. Few Indian Major Players are as under: Hanil Lear India Pvt. Ltd. Hi-Tech Elastomers Ltd.
