Aluminum product is one of the non-ferrous metals in the metal category. Due to its wide application, aluminum profiles are widely used in furniture manufacturing.
The aluminum profile adopts the extrusion molding process, that is, after the aluminum ingot and other raw materials are melted in the furnace, they are extruded through the extruder to the die to flow out and form. It can also extrude various profiles with different cross-sections. The main performance, namely strength, hardness and wear resistance, are in accordance with national standards.
The treatment process adopts anodizing treatment, and the surface treatment oxide film reaches a thickness of 0.12m/m. The wall thickness of the aluminum profile is selected according to the optimization of the product design. It is not the thicker the better on the market. It should be designed according to the cross-sectional structure requirements. It can be uneven from 0.5 to 5mm. The layman thinks that the thicker the tougher, it is actually a wrong view.
Aluminum products can be applied to produce iron cast furniture, such as cast iron bench and table, cast iron lawn chairs, cast aluminum patio and cast iron seating in the house, office, patio, and bistro.
Compared with the processing methods of office furniture profiles, die-casting alloys use different equipment. Its raw materials are aluminum ingots (about 92% purity) and alloy materials, which are melted in a furnace and enter the die-casting machine to mold. The shape of the die-cast aluminum product can be designed like a toy, with different shapes, convenient for connection in various directions, and high hardness and strength.
Die-cast aluminum forming process points:
1. Die casting molding
2. Rough polishing to remove residual material from clamping
3. Fine polishing
