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

Failure Mode and Analysis of Aluminum Alloy Die-casting Dies. Aluminum alloy die-casting dies as bearing high temperature, high pressure, and high-speed aluminum liquid carrier, its working environment is extremely harsh. Failure Mode And Analysis Of Die-casting Dies For Aluminum Alloy The vigorous development of the automobile industry and the need for lightweight, so that Aluminum alloy Die-casting is to the large-scale and complex direction of rapid development. Die-casting dies as the main equipment of Die-casting production is to achieve the basic guarantee of high quality and efficient production of Die-casting, its life directly affects the quality of Die-castings, production, as well as the production cost of enterprises and market competitiveness. At present, in most countries, the low service life of the Aluminum alloy Die-casting dies problem becomes the main factor that restricts the further development of die-casting industry, the failure mode of Aluminum alloy die-casting dies is more problematic. 1. Working environment of Aluminum alloy Die-casting dies Aluminum alloy Die-casting dies as a carrier of high temperature, high pressure, high speed Aluminum liquid, its working environment is extremely harsh. When working, the cavity surface is repeatedly flushed by the Aluminum liquid, the specific pressure is more than 40MPa, the inner sprue speed is 30~65m/s, the mold cavity surface temperature can reach 1112°F or more instantly, and after opening the mold, the mold cavity surface temperature drops sharply due to spraying and other reasons. This kind of hot and cold alternating effect in the die-casting cycle repeatedly, making the mold cavity surface temperature changes dramatically. 2. Failure mode and analysis of Die-casting dies According to the field statistics, the common failure forms of Die-casting dies are cracked, cracking, erosion, adhesion, and deformation, etc. Among them, cracked, cracking, erosion, and adhesion mainly occur in the mold cavity surface. (1) Cracked: In each Die-casting cycle, due to the existence of intense heat exchange, the mold temperature changes dramatically, the resulting thermal stress leads to thermal fatigue on the surface of the mold cavity, forming micro cracks. With the increase of Die-casting cycle, the micro-cracks further expand and form crack. This is the main mode of Die-casting dies failure field. (2) Cracking: In the Die-casting production, in addition to thermal stress, due to the high-pressure impact of Aluminum, in the mold internal also produced other stresses. When these stresses exceed the fatigue limit of the mold material will produce cracking, especially easy to produce stress concentration of the sharp corner parts, the possibility of cracking is greater. In addition, if the stress generated during the processing of the mold is not completely eliminated, the mold is more likely to crack. (3) Erosion: Aluminum high speed filling cavity friction heat, so that the surface temperature of the area on the surface of the mold cavity towards the inner sprue, coupled with the violent impact of Aluminum, so the surface protection layer of this part is easy to be destroyed. The Aluminum solution further reacts with the exposed metal substrate to produce harder compounds. In the process of removing these compounds, it is easy to take away the substrate material and expose the fresh surface, and so on, intensifying the damage of the cavity surface, forming a serious erosion. (4) Adhesion: Pressure injection, the instantaneous temperature of the cavity surface at 1112°F. above, at this time, the affinity between the mold material and Aluminum liquid, strong adhesion, easy to form cavity adhesion. (5) Deformation: In the Die-casting process, Die-casting dies to withstand the clamping force, injection backpressure, and other stresses, if the template stiffness is not enough, the mold in these stresses under the long-term role of bending deformation. (6) Movement Obstacle: In Die-casting production, the temperature difference between inside and outside the mold, resulting in different thermal deformation of each part of the mold. Different heat deformation amount leads to different changes in the size of each part of the mold, thus changing the fit relationship between the mold parts. This change of fit relationship may cause significant movement obstruction of the mold parts with relative movement. LINKS： 1. How to Extend The Service Life Of Die-casting Tools 2.
