ALUMINUM AND ALUMINUM ALLOYS are very suitable for extrusion and many types of profiles can be produced from easily ex-trudable alloys (Fig. Note: The melting point of aluminum is approximately 1,220° Fahrenheit (660° Centigrade). Our aluminum extru-sion process is continuously monitored to insure the highest industry standards. The extrusion process makes the most of aluminum’s unique combination of physical characteristics. 5. The insight in the mechanics of the aluminium extrusion process is still limited. The basic process consists of forcing a preheated billet (usually round), placed in a heated chamber, through a die opening by a ram. The Aluminum Extrusion Manual has been updated with new, previously unpublished content! A billet is squeezed from close container to be pushed through a die to reduce its section [1]. Arguably, it is also the most important step —one that not only influences which vendor you choose, but also impacts the manufacturing process, your budget and timeline, and the ultimate results. 2. Process Control in the Aluminum Extrusion Plant 9. A typical process flow is outlined in Fig-1 [Arif et al., 2001]; there might be slight deviations from this general arrangement from plant to plant. Salam International Investment Ltd, ALUTEC, ALAQARIA (Qatar Real Estate Investment Co.), AGR (Aluminum Gulf Ray), Qatar Oman Investment Co. & QBELCO (Qatar Belgium Aluminum Co.). In this process, a piston or plunger is applied to apply a compressive force to the workpiece. About Aluminum Extrusion. In the actual extrusion process, the aluminum billet (a cast "log" of extrusion feedstock) and extrusion tools are preheated. To increase the solubility of products and bioavailability, the hot extrusion process is used. ALUMINUM EXTRUSION ALLOYS. The aluminum extrusion process really begins with the design process, for it is the design of the product – based on its intended use – that determines many of the ultimate production parameters.
