The Advantages And Disadvantages Of Hot Chamber Die Casting Machine
The Advantages Of Hot Chamber Die Casting Machine
Compared with other casting methods, die casting has the following three advantages:
1. Dimensional accuracy, surface accuracy, thin wall
The dimensional accuracy of castings is high, generally equivalent to 6~7, even up to 4; the surface finish is good, generally equivalent to 5~8; the strength and hardness are higher, and the strength is generally 25~30% higher than sand casting, but it is extended The rate is reduced by about 70%; the size is stable, and the interchangeability is good; it can die-cast thin-walled complex castings. For example, the current minimum wall thickness of zinc alloy die castings can reach 0.3 mm; aluminum alloy castings can reach 0.5 mm; the minimum casting aperture is 0.7 mm; and the minimum pitch is 0.75 mm.
2. Mass production
The machine has high productivity and can be multi-cavity in one mold. For example, the domestic JⅢ3 horizontal cold-air die-casting machine can die-cast 600-700 times in an average of eight hours, and the small hot-chamber die-casting machine can die-cast 3000-7000 times in an average of eight hours. , A pair of die-casting molds, die-casting alloys, life can reach hundreds of thousands of times, even millions of times; easy to achieve mechanization and automation.
3. Economic benefits
Due to the precise dimensions of the die-casting parts, the surface is smooth and clean. Generally, it is used directly without mechanical processing, or the processing volume is small, so it not only improves the metal utilization rate, but also reduces a large number of processing equipment and man-hours; the price of castings is easy; it can be combined die-casting with other metal or non-metal materials . It saves not only assembly man-hours but also metal.
4. Surface treatment
Easy to do various surface treatments, such as electroplating, spraying, etc.
Disadvantages of hot chamber die casting machine:
- Due to the high speed of liquid metal filling the cavity during die-casting, the fluid state is unstable, so the general die-casting method is used, and the casting is prone to pores and cannot be heat treated.
- Die-casting is more difficult for castings with complex recesses.
- High melting point alloys (such as copper, ferrous metals), die-casting molds have a lower life.
- It is not suitable for small batch production. The main reasons are the high manufacturing cost of die-casting molds, the high production efficiency of die-casting machines and the uneconomical production of small batches.
- Materials are limited: The current die-casting alloys only have six types of zinc, tin, lead, copper, magnesium, and aluminum, among which copper alloys have the highest melting point.
