(1) What is aging treatment? The method of heating the castings after solution treatment to the set temperature, leaving the furnace for a period of time, and slowly cooling them in the air is called aging. If the aging strengthening is completed at room temperature, it is called natural aging, and if the aging strengthening is completed in an environment higher than room temperature and holding for a period of time, it is called artificial aging. Aging treatment is a spontaneous process of decomposition of supersaturated solid solution, which can restore the lattice of the alloy matrix to a relatively stable state.
(2) What is the annealing process? The process of heating aluminum alloy castings to usually around 300°C, holding it for a period of time, and cooling to room temperature with the furnace is called annealing. During annealing, the solid solution will decompose, and the second phase particles will gather, which can remove the internal stress of the casting, keep the size of the casting stable, avoid deformation, and enhance the plasticity of the casting.
(3) What is solution treatment? Heat the casting to almost the melting point of the eutectic, and then keep it at this temperature for a long time, and then cool it quickly so that the strengthening components can be best dissolved, and keep this high temperature state until At room temperature, this process is called solution treatment. Solution treatment can enhance the strength and plasticity of castings and improve the corrosion resistance of the alloy. The effect of solution treatment is usually related to three aspects: solution treatment temperature, solution treatment holding time, and cooling rate.
The company is a medium-sized private enterprise integrating casting and machining.
The company is located in Dikeng Village, Dongguan City, Guangdong Province, and was founded in the late 1990s. Through years of technological innovation and reform, as well as the continuous accumulation of talents in casting and processing, we now have a complete machinery manufacturing organization and strong financial strength.
The company’s existing plant area is more than 18,000 square meters, fixed assets of 20 million yuan, hundreds of professional and technical personnel, 4 foundry workshops (lost foam, large parts, machine die, copper and aluminum casting), and 4 processing workshops (CNC, Oil pressure, follow-up, spray painting), sand-finishing products and processed parts can be separated. Externally, from 2009 to 10 years, the annual casting output exceeded 8,000 tons, the processing output exceeded 6,500 tons, and the tax revenue was 10,000 yuan.
