Custom Die Casting In China


Customized Die Casting

Die Casting using a mold or a reusable competitive cost mass production manufacturing process is complicated metal parts. This process is highly automated devices; it involves four key elements: metal raw material, the furnace, the mold, and die casting machines.
Metal die casting processes are generally used in aluminum, magnesium, brass, copper, zinc, or several metal alloys. However, the composition of the alloy used may vary, depending on the specifications and product requirements of individual customers.

In the production process, The metal melts in a hot chamber or a cold chamber. Cold chamber furnaces refractory metal such as aluminum, and the hot chamber furnaces low-melting metal such as zinc or a metal alloy.

Once the metal in a liquid state, the die casting machines will be forced into a mold, and then rapidly cooled and solidified into the desired shape.

The die casting process is almost automated, so labor costs are low. However, the high-costed complexity of using the steel die and the die casting tools require mass production in order to a relatively low cost per unit.


Die Casting Metals And Alloys


The die casting process usually uses aluminum alloys, magnesium alloys, and zinc alloys. The choice of a particular alloy depends on the physical properties and design features required for the final casting. Quality such as density, corrosion resistance, melting point, and strength may be decisive factors along with cost factors.

Aluminum metal


Copper metal


Each metal used has specific properties, in certain cases, it may prove advantageous. For example, aluminum alloys generally have the advantages of lightweight and corrosion resistance.

In contrast, the copper alloy generally higher cost but has excellent electrical conductivity.

The required part design features may also greatly influence the choice of materials used for die-casting parts.

Certain metal alloys (e.g. Zn) exhibit a high degree of ductility for parts having better surface finish and a thin, these alloys could be a good choice.

Zamak is an acronym of the German names for the metals of which the alloys are composed: Zink (Zinc), Aluminum, Magnesium and Kupfer (Copper).

The most common zamak alloy is zamak 3. Besides that, zamak 2, zamak 5 and zamak 7 are also commercially used. These alloys are most commonly die casting.

The choice of material also affects the processing possibilities.

Aluminum alloys with much higher melting points require cold-chamber die casting machines, While zinc and other alloys melt at low temperatures using hot-chamber die casting machines.
