Ciccola, Alreyven Extrusions, Venezuela Abstract Aluminum extrusion process is usually characterized for a large set of parameters changing with every profile or shape to be manufactured.
Normally extruders have to deal with a large numbers of profiles every year making it difficult to analyze each one to look for the best configuration on each case; even though today FEM analysis and different simulations are being performed with relative success, it is economically not possible to apply this method to analyze a large set of shapes.
In these studies, extrusion solver is coupled with a stress analysis solver to consider the effect of die deflection on the extrusion results.
Focus of the work is on the accuracy of tool deflection analysis.
Depending on how the tool material is modeled results predicted could vary. In this work, the tool deformation and stress analyses are performed by modeling the tool as elastic, elastoplastic, temperature dependent elastoplastic material.
Aluminium with its specific versatile properties and suitable adapted alloys became the fastest growing metal for various products worldwide. The quenching solver presented in this work computes temperature, cooling rates, quench factor, grain size, and warpage.
LLC — UAE Abstract The main objective of this paper is to define a correlation between the surface roughness of the extruded Aluminium to that of the number of billets extruded for a given die; in other terms this study tries to relate the surface roughness of the extruded aluminum to the deterioration of the nitrided layer over the number of billets run over a production cycle.
In this study we monitor the surface roughness of the extruded aluminium right from the start of extrusion wherein the die has just been nitrided by an optimum nitriding cycle to the surface roughness of the extruded aluminium over a finite number of billets run over the same die, and at the same time study the deterioration of nitrided layer over this extrusion cycle.
Within this study we have also considered the influence of use of nitrogen cooling during the course of extrusion and its effect on the nitrided layer and also the surface roughness of the extruded aluminium.
Due to International Regulations that are going to be implemented, developing countries will soon have to follow this trend. The paper initially presents the use of Thermal Break Aluminum extrusions in the manufacturing of windows, doors and curtain walls systems, its development through the years and different Thermal Break solutions used in various part of the world.
Then it describes the various equipments that are necessary to implement for the assembly of Thermal Break Aluminum extrusions. Finally various types of thermal break assembly lines and plants with different productivity rates and different levels of automation are presented. This review surveys the landscape of worldwide developments and improvements in the aluminum extrusion industry which have been reported in Light Metal Age in recent issues, starting from the August to the June issue.
In fact, since July and continuing on to Junethere have been some 1, aluminum extrusion articles, editorials, and news bulletins published in the magazine, now available from Light Metal Age LMA as a digital archive on a USB drive.
This review Part II also takes the same holistic approach, but also presents the changing supply and demand environment that exists in the industry today, that is, international trade issues on imported extrusions and the expanding market demand for lightweight automobiles and trucks Read Full Article.
The extrusion process is an economic maunfacturing method used to produce profiles with a constant section. These problems are related to the complex nature of the process that has to guarantee, at the same time, proper conditions for a good welding in case of hollow profilesabsence of profile distorsions, an acceptable die stress and as much as possible fast extrusion.
Usually, the optimization of the extrusion process is performed by the operators on the basis of consolidated experience and empirical rules.
However, in this way, it is extremely difficult to control all the process and geometrical parameters involved and then to control the final outputs Read Full Article. Medium and large extrusion presses and extrusion systems find a large application in the production of automotive and industrial products but at the same time are also used for different applications ranging from building systems up to heavy and wide profiles for railway application.
These different type of extrusions involve certainly many different aspects and sometimes they must be really approached as different industries but two factors remain always unvaried, whatever the final products are: Turla acquisition data system.EVALUATION OF SOLID WASTE MANAGEMENT IN SATELLITE TOWNS OF MOHALI AND PANCHKULA–INDIA Rishi Rana, Rajiv Ganguly, Ashok Kumar Gupta *.
