Dongguan precision casting castings have a great impact on mechanical products. The mechanical properties depend to a large extent on the quality performance of the castings. Therefore, mechanical products have high requirements for castings, and mechanical products require the castings to be durable under different conditions. Ability, including wear resistance, corrosion resistance, chilling and heat resistance, fatigue, shock absorption and other performance, as well as machinability, weldability and other process performance. These quality properties have a direct impact on the working efficiency and service life of mechanical products. Different casting materials make the performance characteristics of the casting itself different.
The output of cast steel is relatively stable, while the quality, variety, performance, and proportion of alloy steel and special steel of cast steel continue to increase. The use of various refining processes and technologies to develop new cast steel materials can improve the strength and toughness and special properties of the materials.
Because of its low density, high specific strength, and corrosion resistance, cast light alloys will be more widely used in various industries such as aviation, aerospace, automobiles, and machinery. In the automotive industry, in order to reduce fuel consumption and increase energy utilization, it is a long-term development trend to replace steel and iron castings with aluminum and nickel alloy castings. Among them, it focuses on solving pollution-free, high-efficiency, easy-to-operate refining technology, metamorphism technology, grain refinement technology and rapid detection technology in front of the furnace. In order to further improve the material performance and maximize the potential of the material, high-quality aluminum alloy materials, especially aluminum-based composite materials, can be developed to meet the performance requirements of different working conditions, strengthen the research of cluster alloy technology, and continue the alloy die casting and squeeze casting process And related technology development research; perfect ferroalloy smelting equipment and related technology and process development research.
Composite materials will become a new type of engineering material in the 21st century. Casting composite materials will be devoted to the development and research of metal matrix composite base materials and reinforced component materials, and accelerate the development and research of their applications.
Iron is our most common casting material. Iron castings have low cost, good manufacturability, remelting and regeneration to save resources and energy, so the application and development of this material will last forever. Extensive use of advanced molten iron desulfurization and filtration technology; thin-walled high-strength cast iron manufacturing technology; cast iron composite material manufacturing technology; cast iron surface or local strengthening technology; isothermal spheroidal graphite cast iron complete set of technology; metal casting and metal molds Special techniques and equipment such as sand-coated casting and continuous casting.
With the continuous development of the national economy, Dongguan precision casting enterprises have higher and higher requirements for the performance of mechanical equipment. Therefore, the important parts of the mechanical products also need to be improved and improved in quality and performance from the local quality performance. Improve the performance of the entire mechanical product.
