The original material: first, it needs to produce the alloy that is suitable for the aluminum sheet, and calculate out the using amount, and the different alloy need to be mixed by the proper proportion. Then, the mixed alloy need to be put into the smelting furnace, and the gas and the dirt will be removed through the scientific method.
The next step is the casting, the aluminum liquid need to be casted by the special technology, it will be casted to the shape that you want. Pressing is the important way for the material to form the shape, which can complete the heat procession.
