Optimisation of Cleaning Chamber and Conventional Extrusion-Die Tools

Aluminium is the metal of the future. Its use knows no bounds. The diploma thesis will address the processes of forming aluminium alloys for extrusion and their application, which are the result of research by the company Impol. With the help of process operators and analytical records, he will compare the previous state of the technological process with new findings and define them with substantiated evidence in the further work process. In the thesis, he will test the effectiveness of ** ultrasound** during the reaction process and completed cycles for more efficient disassembly of extrusion tools.

Problem

Aluminium is the metal of the future. Its use knows no bounds. It is used in one form or another in all economic sectors.

It can be found in households, where it is used for food packaging, in construction, the aviation and automotive industries, space technology, etc. The processes of forming aluminium alloys are carried out in several different ways, such as rolling, extrusion or forging, precisely because the casting combination of alloyed elements provides the possibility of use in global sectors. In the industry of metal semi-finished products and products, it is also necessary to attribute supporting processes, such as maintenance, remediation and corrections for ongoing industrialisation.

Solution and Method

In the diploma thesis, he will address the processes of forming aluminium alloys for extrusion and their application, which are the result of research by the company Impol. He will pay more attention to tool remediation, as this is the work he performs. He will explain the different ways of using extrusion tools, preparation, storage, correction and cleaning of tools, the machines required for this purpose and the problems of selecting the appropriate tool geometry for extrusion.

The key purpose of the thesis is to explain the technology of the etching process in terms of usability, wear and efficiency, and to establish optimisation by shortening time cycles and consequently reducing costs.

Results

With the help of process operators and analytical records, he will compare the previous state of the technological process with new findings and define them with substantiated evidence in the further work process. In the thesis, he will test the effectiveness of ultrasound during the reaction process and completed cycles for more efficient disassembly of extrusion tools. By different sorting and combinations of loading tools into the system, he will investigate the most efficient option for carrying out the work.

This would consequently relieve the operator, reduce time cycles and costs of process quality. The diploma thesis should be a kind of proof of a useful proposal to the company in which he is employed. He proposed the remediation of ultrasound to the existing state for faster and more efficient removal of Al-alloys from the tool, whilst saving on the quality of the lye and subsequent surface durability of the extrusion tool.

The purpose of the diploma thesis is to improve the quality and quantity of work in the process of cleaning extrusion tools with sodium hydroxide through theoretical sources, research and practice. The emphasis in the diploma thesis will also be on familiarising operators with safety and health in the correct handling and working with lye, whereby potential hazards in the etching process could be avoided.
