The die-casting aluminum radiator has more than 60 years of history, and is widely used in Europe. At present, the usage rate in China is still very high, and the popularity is not strong, so this kind of radiator is not well understood by many people. The main feature of die-cast aluminum radiators is that each column head has a die-casting air guide plate, column It is connected to the column to form a piece through inscribed connection. Today, the editor will introduce you to the relevant knowledge of die-casting aluminum radiators . You can learn about it through the following introduction!
Is the die-cast aluminum radiator ok-advantages
1. High dimensional accuracy of castings, generally equivalent to 6 ~ 7 grades, or even up to 4 grades; good surface finish, generally equivalent to 5 ~ 8 grades; high strength and hardness, the strength is generally 25 ~ 30% higher than sand casting. But the elongation is reduced by about 70%; the size is stable and the interchangeability is good; the aluminum thin-wall messy casting can be die-casted. For example, the minimum wall thickness of current zinc alloy die-casting aluminum parts can reach 0.3mm; aluminum alloy castings can reach 0.5mm; the minimum casting aperture is 0.7mm; the minimum pitch is 0.75mm.
2. The machine has high productivity, for example, the domestic Jâ…¢3 horizontal cold-air die-casting aluminum machine can die-cast aluminum 600-700 times evenly for eight hours, and the small hot-chamber die-casting aluminum machine can even die-cast aluminum 3000-7000 times every eight hours; Long, die-cast aluminum mold, die-cast aluminum bell alloy, life can reach hundreds of thousands of times, or even millions of times; easy to complete mechanization and automation.
3. Due to the fine size of die-cast aluminum parts, the surface is bright and clean. Generally, it is used directly without mechanical processing, or the processing volume is very small, so it not only improves the metal utilization rate, but also reduces a lot of processing equipment and man-hours; the price of castings is cheap; combination die-casting aluminum can be used to other metal or non-metal materials . It saves both assembly time and metal.
Is the die-cast aluminum radiator ok-disadvantages
1. Due to the high speed of the liquid metal filling cavity and the unstable flow state when casting aluminum, the general die casting aluminum method is used, and the casting is prone to blowholes and cannot be heat treated;
2. Die casting aluminum is more difficult for intricately recessed castings
3. High melting point alloys (such as copper, ferrous metals), die-casting aluminum type has a lower life;
4. It is not suitable for small batch production. The main reason is that the die casting aluminum mold has high manufacturing cost, the die casting aluminum machine has high production efficiency, and the small batch production cost is not economical.
The above is the die-cast aluminum radiator brought to you by the editor and the advantages and disadvantages of the die-cast aluminum radiator . After reading it, do you know more about this aspect?
