Die-casting production process is capable of producing a geometric reusable mold by use of complex metal parts, known as dies. Precision die casting process involves the use of a furnace, metal, die-casting machines and molds. Metal, usually a non-such as aluminum, zinc alloy, is melted in the furnace, and then in the die-casting machine mold injection. There are two die-casting machine die-casting – the main types of hot-chamber machines (used for low melting temperature, such as zinc, alloys) and cold chamber machines (used for melting temperatures are high, such as aluminum and alloys). The difference between these machines will be set out in the equipment and tools section. However, in the two machines, molten metal injected into the post-death, it is quickly cooled and solidified the last part, called casting. The steps in this process described in more detail in the next section.
Investment is created in this process, and can vary greatly in size and weight, from a couple castings ranging from ounces to 100 pounds. One die-casting of general application, Block – thin-walled shell, often require a lot of ribs and internal boss. For a variety of appliances and equipment, metal shell, often casting. Several auto parts also used die-casting manufacturing, including the pistons, cylinder heads, engine blocks. Other common die-casting parts, including the propeller, gears, bushings, pumps and valves.
