Inspection of painting treatment and bundling to identify the aluminum alloy materials
The ingredient composition and bubble inclusion of aluminum alloy materials should satisfy the required quality specifications.
Melting should be done in the shortest time by feeding ingot and collecting device in the electric furnace equipped melting and insulation function.
Fluxing N2 gas is sprayed using the pressure into the liquid of electric furnace in which the melting is completed to remove the remaining hydrogen gas and dross.
Refining of microstructure(Eutectic)
Casting is a manufacturing process by which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify.
Air pressure hammer is vibrated to remove the sand core from the casing products.
The feeding hole and liquid-flowing unit are removed whith cutting from the sand-removed product and this process may be auto-matic or manual depending upon the structure of the product.
Heat treatment of aluminum
aluminum is T6 heat treated for artificial improvement of toughness, processability, density, durability, and mechanical strength that are the weakness of aluminum.
Micro STS balls are sprayed at high pressure to the heat-treated casting product rotating the impeller in order to remove the remaining sand core, burr, small precipitation, and staining from the casting aluminum surface.
Visual total inspection, sample inspection for major dimensions, and sample inspection for hardness.
Sample appearance inspection, package inspection, and quantity check.
Checking ID mark, checking first-in-first-out principle, checking loaded status, and checking consistency with the ordered specifications.
