Extrusion is a process equally suitable for the simplest shapes and for the most complex for the wide range of large and the small items for structural members or for decorative trim. Some sections produced by extrusion cannot be made by other process economically. The two main advantages of this process over other manufacturing processes are its ability to create very complex cross-sections and work materials that are brittle, because the material only encounters compressive and shear stresses. It also forms finished parts with an excellent surface finish. Aluminium sections made by the extrusion process offer many advantages. The aluminium industry can be categorized into two principal segments. The key segment is the production of primary aluminium by integrated producers engaged in the entire value chain from the mining of bauxite in an alumina refinery, and conversion of alumina into primary aluminium metal. The second principal segment consists of secondary/downstream producers who are engaged in the manufacture of value-added semi fabricated aluminium products such as rolled products, extrusions and foils. The cost of an extruded aluminium sections depends on many factors such as alloy, temperature, overall size, weight per meter, complexity of design, quantity and tolerance requirements. As a general rule the cost per meter of an extrusion increase where high strength alloys are used and it decreased in range that designers have its yet fully exploit the possibilities of sections made in this way. The extrusions segment is the preserve of the secondary producers with nearly 40 players, such as Jindal Aluminium, Century Aluminium, Sudal Industries, Bihar Extrusions and Bhoruka Aluminium, which account for over 80 per cent of the aggregate production capacity of tonnes. Primary aluminium producers such as Indal, Hindalco, Balco and Malco account for the remaining of production capacity. The capacity overhang can be gauged from the fact that as against an aggregate capacity of Tonnes, the domestic demand is currently only around tonnes. The dependence on exports will be critical to the survival of the secondary, players in the extrusion markets. Extruded aluminium products are finding growing exports prospects. Aluminium extruded products are mainly tubes, pipes and blanks. These are manufactured in various forms and can be broadly classified in (a) rods & (b) sections. Sections include hollow and solid sections. In extrusion, the cylindrical rod called billet, is squeezed hydraulically into any shape by forcing the hot billet through the die orifice. Extrusion presses of various sizes are available ranging from 200 ton to 5000 tons capacity. These presses can be designed from simple to very complicated type with intricate and most sophisticated component. Aluminium extrusion products are widely used in transport industry, railroads, electronics and housing industry etc. Extrusion process achieves cheaper, lighter and neater products. The Indian aluminium industry is currently going through an expansionary phase. All domestic players the Birla’s to the Aggarwal of Sterlite and the state owned Nalco are expanding their capacities, with a view to cater to an expected rise in local as well as overseas demand. Hindalco, Balco, Indal, and Jindal extrusion Ltd are the major producer in this segment. The extrusions market is expected to grow at an annual rate of eight percent over the next few-year. The exports of aluminium-extruded products are gradually on rise. Afghanistan, Algeria, Bahrain, Bangladesh, Burma Hong Kong, Kenya, Kuwait, Oman, Sri Lanka, U.A.E. etc. are the main middle East countries to whom aluminium extruded products like tubes, pipes and blanks are being exported. At present aluminium extrusion products have penetrated a large area of applications and are manufactured in India with or without foreign collaborations. It requires moderately high level of technology and investments but the industry is quite profitable and finds ready market within and outside the country. The complete range of plants and machinery are available indigenously and compare well with imported extrusion plants. Looking at the future scopes for aluminium extruded sections, it can be foreseen that new entrepreneurs will find it quite attractive to come up with good production targets.
