Extrusion can be referred to as a process used in developing or creating objects with a fixed cross sectional profile according to various search engines . The material is drawn or pushed through a dye of a desired cross section. The 2 important advantages of an extrusion process is the ability of developing a complex cross section and materials which are brittle since the materials only go through shear and compressive stresses. In addition it can also create finished parts with a beautiful surface finishing. Some of the commonly extruded materials include metals, ceramics, foodstuff, polymers, and concrete. Plastic extrusion machinery, steel extrusion machinery and aluminum extrusion machinery are examples of the available extrusion machinery.
The industrial sector today is ready for greater growth. Each passing year, FDI continues to grow and the market seems bullish. More and more economists are nowadays advocating for bigger investments in the industrial segment, especially the machinery segment for starting up the foundation of a promising growth. These economists insists that non-machinery products and manufacturing sector are expected to not only perform well, but also holds a potential in creating close to 223400 jobs.
Some industry insiders also reveal that the key sectors which be responsible for growth include the plastic extrusion machinery, electronic ballasts and hot rolling mills.
Since the plastic extrusion machinery are considered as among the most sought after machines, the demand often outweighs their supply. The plastic extrusion is basically a process which involves the melting of raw plastic material and then shapes it into a product as per the desired requirement and demand. The plastic extrusion machines can produce things such as tubes, adhesive tape, window frames, deck railings, wire insulation, fence and pipes.
Nowadays, many companies have taken up the extrusion of aluminum. Such companies specialize in the creation of aluminum products for their buyers. The aluminum extrusion machinery mainly plays the role of producing homogeneous cross section. The process simply involves aluminum materials being squeezed all the way through an outlet under a very high pressure. The aluminum extrusion machines are very popular around the world because the metal is readily available on the crust of the earth. Additionally, aluminum is used in a lot of applications and also has several advantages.
The products of aluminum extrusion will last for longer period compared to the plastic and steel extrusion machinery products. Extrusion is also meant to be an economical environmentally friendly solution.
According to the latest forecast, the employment capacity has registered a huge growth in 2010 and is expected to show further growth in 2011 in all the sectors.
