Nowadays, the competition of sheet metal processing industry is not very fierce. When we are processing all kinds of sheet metal parts, we must take customers as the first, the customer satisfaction as the standard, the use of good materials and the good process.
For sheet metal processing industry, construction is also needed.
At present, there are two main types of aluminum profile market in China: one is the building aluminum profiles, and the aluminum profiles are mainly used in various civil and commercial buildings; two are industrial aluminum profiles, and industrial aluminum materials are mainly used in other industrial fields except the construction field, of which the transportation and Mechanical and electrical equipment are industrial aluminum profiles. Major consumption areas.
At present, the market proportion of aluminum profiles in the domestic market is higher than that of industrial aluminum profiles, because the construction industry is still the main consumption field of aluminum profiles in China, and the demand for the consumption market is more than 60%.
We usually meet the cold rolled steel, steel, cast aluminum and other materials, their sheet metal processing methods are very different, following the analysis of the three of the processing characteristics:
The most used materials for cabinet now are cold-rolled steel plates. The cold rolled steel plate has no oxidation reaction at normal temperature, so the surface quality is good, the precision of the size is high, and the mechanical and technological properties of the annealing treatment are better than that of the hot rolled sheet.
Steel bar cabinet is a structural form of assembling steel section and steel plate bending combined welding or steel section welding with aluminum alloy castings. It can meet the general ship conditions. However, because of the deformation of steel sections, the deformation of the cabinet is large and the participation stress can not be eliminated, and its precision is poor.
Cast aluminum cabinet is made of cast aluminum or piecewise processing. It has good compression and torsion resistance, anti-seismic and impact resistance and heat dissipation. In addition, the surface processing quality of the cabinet is good, the appearance is beautiful, and the dimension precision is high. But the weight is slightly heavier than other types of cabinet, and the manufacturing cost is high and the production cycle is long. So now the most commonly used sheet metal processing is the cold rolled steel plate of this material cabinet. However, if the demand for industrial aluminum profiles is rising quietly from the change of consumption structure, the demand for aluminum profiles in industrial fields has accelerated in recent years, and the consumption ratio has increased year by year, up from 31% in 2008 to close to 37%. Among them, the consumption of aluminum profile is the most significant in the transportation field, especially the construction of rail transit, which has become an important force to stimulate the demand of industrial aluminum profile.
