Die Casting
Die casting is a process of casting metal under pressure to produce casting. The metal or metal alloy is melted, then poured into a prepared mold and allowed to cool. The molded piece is then removed from the mold and processed further by one or more of a great variety of process. There are three primary variations of the die casting process: (1) the hot chamber process, used for lower-melting metals such as zinc and magnesium; (2) the cold chamber process, used for higher-temperature melting metals such as aluminum; and (3) the direct injection process.
Improvement technology in both the alloys used in die casting and the process itself, die casting applications are expanding into almost every known market. Today, die casters can produce castings in variety of sizes, shapes and wall thicknesses that are strong, durable and dimensionally precise.
Aluminum Die Casting
Aluminum is one of the most widely used materials in the die casting industry. The raw material for aluminum die casting is largely recycled aluminum cans and other articles. Aluminum die casting is different from other metal die casting processes in several ways that make aluminum die casting a widely used industry standard. The first step in an aluminum die casting operation is to crush, shred, and sort the raw material. Then, the raw material is melted, by use of careless and channel induction furnaces, crucible and open-hearth reverberatory furnaces fired by fuel oil or natural gas, or electric resistance and electric radiation furnaces.....then finally, the die casting is cleaned by use of alkaline and/or acid solutions.
In fact, aluminum die casting has been an extremely used in all parts of the world generating parts and items, which have become house hold items and daily requirements tools, as well as, aluminum die casting manufacturing units produce a plethora of products ranging from parts in automobile industries all the way to tools that are heavily used in the construction industry.
Zinc Die Casting
Zinc is the other major material for die casting. This is lower-melting metal is normally use hot chamber process. The first step is to crush the scrap metal and prepare it for melting. Then, the metal is melted at temperatures between 325 oF and 475 oF.....finishing may include texturing by acid-etching or other process, electroplating, or polishing.
[Advantages of Die Casting]
Die casting is an economical and efficient process, which offers a wide range of shapes and components than any other manufacturing technique. The Die Casting manufacturing process offers many advantages and benefits. When functional products are designed for volume production, the high-pressure die casting process is one of the prime production options considered by product engineers.
- Die casting is produced at high-speed production. Only little or no machining is required.
- Die casting provides complex shapes
- provides complex shapes within closer tolerances than many other mass production processes.
