The following points highlight the five main types of die casting alloys used in industries. The types are: 1. Zinc-Alloys 2. Aluminium-Alloys 3. Copper Base Alloys 4. Magnesium Base Alloys 5. Lead and Tin Base Alloys. Type # 1. Zinc-Alloys: They are most widely used as die casting alloys (as over 75% of die castings produced are zinc base). The [...]
The use of ribs, hubs and bosses should be made in such a way that the weight is reduced, the part is strengthened and the general appearance is improved. Thick sections tend to cause the die to run hotter and, therefore, shorten die life. In addition, cooling of a large lump may cause porosity and give trouble if drilling is [...]
The die is most important part in die casting machine which will be discussed here in detail. Dies for all the machines are similar in construction as there is little difference in the method of holding and operating them. Generally it is made into two halves so that the casting can be easily removed from it after solidification. One part [...]
