Hi, I am looking for someone to write an article on aluminum rims production in a flexible manufacturing system Paper must be at least 1500 words. Please, no plagiarized work! Multi-Spoke Aluminum rim is complex. The best method to be used is to die casting. This method allows for the production of complex parts. The use of aluminum casting in the automotive industry has tremendously increased over the past decades. The driving force for the increase in automotive weight reduction for efficient and improved performance. For aluminum alloy rim production, Al-Si casting alloys commonly used as raw materials. The use of Al-Si is majorly informed by its excellent casting properties. The main alloying materials of Al-Si castings include Magnesium, Silicon, Manganese, Iron, Strontium, Beryllium, Titanium, and zinc.
Each material gives special features to the alloy casting so that the resulting has desired properties. The percentage compositions of these materials greatly affect the final alloy properties. Aluminum casting alloy rims are produced through the use of low-pressure die casting. This method is used due to its many advantages. Some of the advantages of this process include design versatility, high dimensional accuracy, good surface quality, low equipment & dies cost, high productivity, good mechanical strength, and its economic nature.
For the melting process, electric furnaces and reverberatory furnaces are used. After the process of melting, the molten metal normally has two transfer operations: Firstly, there is the transfer of the molten metal between two furnaces, i.e., from the melting furnace to the holding furnace. The molten metal is then automatically transferred from the holding furnace to a shot chamber of the die casting.
Degassing is the process of removing hydrogen gas from a metal melt. Before the start of die casting, the molten metal from the holding unit is taken through a degassing process. The inert gases are normally used for degassing operations of aluminum melt. For inert gasses, the removal of hydrogen gas from a molten metal depends on the reaction at the molten metal-gas bubble interface. The reaction is as shown below.
