Introduce the difference between aluminum die-casting and machined aluminum

The heat dissipation and good appearance of aluminum alloys have surpassed the current plastic materials, and the weight of the weight itself is irreplaceable by plastics. So, do you know the difference between machined aluminum and aluminum die casting?
The following small series to introduce to you.
1. Material difference: Aluminum die-casting alloy generally adopts ADC12 or ALsi9cu3, and automobile aluminum generally adopts 6063 or 6061.
2, the difference in appearance: aluminum die-casting is equivalent to plastic injection molding process, can produce any shape, the outer casing of the street lamp is generally aluminum die-casting. The shape of the equal section of the aluminum is small, such as the heat sink of the bulb, the aluminum profile of the door and window.
3. Thermal conductivity: The general conductivity of aluminum die-casting is about 80-90W/M.K, while the thermal conductivity of aluminum is about 180-190W/M.K.
4. Cost: The cost of die castings and aluminum is relatively high, calculated by weight and machining. Calculate costs based on real-time material prices and labor. Relatively speaking, the cost of aluminum die casting is higher, but the specific situation should be analyzed.
5, production efficiency: injection molding production efficiency is certainly higher, mass production, generally more than 1,000 a day, and the size is stable, the shrinkage rate is 0.5%. There are more ingredients in the aluminum machine processing. As the name suggests, it is the aluminum of the car, and the efficiency is naturally lower. Want to know more about Yuxin Company
