Q: Zinc alloy door handle production process?
A: 1. Design zinc alloy door handle drawings
2. Make molds
3. Melt and prepare zinc alloy
4. Cast with zinc die-casting machine
5. Trimming and finishing
Q: hot chamber die casting process
A:1.Metal pretreatment: Place low melting point alloys such as zinc alloys into a furnace in a hot chamber die-casting machine and heat them to a molten state.
2. Mold preparation: The mold is installed on the hot chamber die-casting machine and a cooling system is set up for demolding.
3. Injection process: Molten metal is injected into the mold from the furnace through a gooseneck, and the injection punch fills the metal into the mold cavity under pressure.
4. Cooling forming: After the metal is cooled and solidified in the mold cavity, the die casting is taken out by opening the mold.
Q: Difference between hot chamber and cold chamber die casting
A: Hot chamber die-casting machine:
1. The chamber(gooseneck) is immersed in an alloy liquid that maintains a constant temperature. This design allows the molten metal to be directly injected into the mold under high pressure, simplifying the operation process.
2. Used for casting low melting point metals such as zinc, copper, and lead.
Cold chamber die-casting machine:
1. The chamber and furnace are separate, and the molten metal needs to be poured from the crucible into the injection chamber for injection.
2. Used for high melting point metals such as aluminum, magnesium, copper.
Q: What are the benefits of hot chamber die casting?
A: The main advantages of hot chamber die-casting machines include high production efficiency, low metal consumption, stable process, and easy automation. Due to the fact that metal alloys are always in a molten state, injection and solidification processes can be rapidly and continuously carried out, thereby improving production efficiency. In addition, the metal liquid of the hot chamber die-casting machine is automatically replenished into the injection chamber under the action of gravity and vacuum force, without the need for separate pouring, further simplifying the production process.
Q: What are the disadvantage of hot chamber die casting?
A:1.Limited range of applicable materials: Hot chamber die-casting machines are mainly suitable for die-casting of low melting point metals such as zinc, magnesium, tin, etc., so the material selection is relatively limited.
2. Injection ratio is smaller: There is no pressure increase during the injection process, which reduces the pressure on the mold by the equipment, thereby extending the service life of the mold.
Suitable for small and medium-sized parts: Hot chamber die-casting machines are particularly suitable for producing small and medium-sized parts, capable of producing parts with complex details and excellent surface smoothness.
