Metal die casting processes are generally used in aluminum, magnesium, zinc, or several metals alloys, However, the composition of the alloy used may vary, depending on the specifications and product requirements of individual customers. 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. Free Quote & Part Analysis → 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 Magnesium Zamak alloy Cooper 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. -Copyright Wikipedia 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. contact

This article will explain the working principle and correct operation method of cold-chamber die casting machine How does cold-chamber die casting machine work During operation, the pressure chamber is placed vertically, and the upper punch is above the pressure chamber, and the lower punch is located at the position where the nozzle orifice is blocked, to prevent molten metal from pouring into the pressure chamber and flowing into the nozzle hole by itself. The opening and closing movements of the mold move horizontally. After the mold is opened, the die casting remains in the movable mold. The working steps of the cold chamber die casting machine are as follows: Close the mold. Pour molten metal into the press chamber manually or by other means. The upper punch moves down at a lower injection speed and enters the pressure chamber until it just touches the molten metal surface. When the upper punch is turned to a higher injection speed and pressed down, the lower punch and the upper punch will move down synchronously while maintaining the relative distance between the upper punch and the molten metal. When the lower punch moves down to let out the nozzle orifice, it just descends to the nozzle part and is supported, therefore, the upper and lower punches squeeze the molten metal at high speed to the nozzle hole (part of the sprue) injection. The molten metal is filled into the mold cavity from the inner gate through the sprue composed of the nozzle, the sprue sleeve, the tapered hole of the fixed mold, and the diverter. After the filling is completed, the upper punch can still maintain a certain pressure until the molten metal in the cavity is completely solidified into the die casting 1, and the molten metal in the runner and the pressure chamber solidifies into the direct gate and the remaining material respectively cake. The upper punch lifts and resets; at the same time, the lower punch moves upwards to cut away the remaining cake that is still connected to the straight gate. The lower punch continues to rise, lift the remaining cake out of the top surface of the pressure chamber, and then take it away manually or by other means. Move the lower punch down and reset to block the nozzle orifice. Open the mold, the die-casting part and the straight gate remain on the movable mold together, and then eject and take out the die-casting part; once the remaining material cake is cut away, the mold opening action can be executed immediately, or it can be executed at an appropriate time, Has nothing to do with the movement of the lower punch to complete the lifting and resetting.
