KMC Aluminium is the Chennai leader in standard and custom alloy aluminum extrusions. Our national network of production and supply facilities enables us to produce all shapes, sizes, alloys and temples suitable for any type of application.
The aluminum extrusion process begins with a solid cylindrical block or a metal block. It is heated until soft and then forced through a steel die to produce lightweight, strong, corrosion resistant components that are shaped like the die opening. • The two conventional methods of extruding aluminum are:
Direct extrusion • This is the most common method. The billet is placed in a stationary container while a hydraulic ram is moved to push it through the die opening. Aluminum flows in the same direction the ram travels. • Indirect extrusion • In this method, the die remains in place while the aluminum billet and container move in unison. Ram pressure forces the soft metal to flow through the die opening in the opposite direction to the ram. This is also called back extrusion.
The extrusion process can be continuous, to produce long components, or semi-continuous, to produce many parts, and the parts can range in size from one millimeter to several feet in length. Extrusions can be manufactured in complex shapes due to the light weight and malleability of aluminum, such as hollow and multi-chamber profiles that would never be possible with other metals. • Think of extrusion like squeezing toothpaste out of a tube. The continuous stream of toothpaste will take the shape of the round tip, just like an aluminum extrusion will take the shape of the die. If you flatten the tip of a toothpaste tube, a flat ribbon of toothpaste will come out. If you change the tip, you can produce a completely different shape. With the help of powerful hydraulic presses that can exert 100 to 15,000 tons of pressure, aluminum can be extruded into almost any shape imaginable.
During extrusion, maintaining temperature control is a crucial element of the process of aluminium profile suppliers. The temperature of the container must remain constant at all times during the cycle, from top to bottom and front to back. The temperature is limited by the alloy that is used and the shape that is extruded. For example, lower extrusion temperatures will generally produce shapes with better quality surfaces and more accurate dimensions, while excessive temperatures can decrease tensile strength. • Aluminum's ability to conduct heat makes it ideal for use as thermal shielding or heat transfer components. The surface of extruded parts can be finished in many different ways, such as anodizing, painting, and powder coating. Each process creates a coating with unique characteristics that can be used in a wide variety of commercial, industrial and consumer applications.
With extrusion presses in India, KMC Aluminium has the ability to supply all shapes, sizes, alloys and temples using direct and indirect extrusion methods and they are one of the best aluminium profile manufacturers. From standard and custom extrusions that require basic procedures (such as precision cutting, drilling, threading, or punching) to completely finished components and assemblies, we can meet all of your extrusion requirements.
