WHAT IS DIE CASTING, HIGH PRESSURE DIE CASTING AND PERMANENT MOLD CASTING?

Die casting is a metal casting industry technique, which is characterized by forcing molten metal under high pressure into the film cavity. Membrane chambers are made using two hardened tool steel molds. These molds are machined into a certain shape during processing and work in a similar way to injection molds.

Die Casting Definition
Die casting is a manufacturing process in which molten metal is poured or forced into steel molds. That can produce geometrically complex metal parts through the use of reusable molds, called dies.
The term “gravity die casting” refers to castings made in metal molds under a gravity head. It is known as permanent mold casting in the U.S.A. and Canada. What we call “die casting” here is known as “pressure die casting” in Europe. In summary, die casting can be called as permanent mold casting, (high) pressure die casting and die casting. This is because each region's alternative statements of die casting are different, but it all means the meaning of die casting.

Die Casting Features
Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminum, magnesium, lead, pewter, and tin-based alloys. Aluminum, zinc, and magnesium are the most commonly used die casting alloys.is melted in the furnace and then injected into the dies in the die casting machine.
 
Die castings are characterized by a very good surface finish (by casting standards) and dimensional consistency. The die casting process involves the use of a furnace, metal, die casting machine, and die. It is accomplished by forcing molten metal under high pressure into reusable metal dies. The process is often described as the shortest distance between raw material and finished product. The term “die casting” is also used to describe the finished part. So die casting features are a manufacturing process for producing accurately dimensioned, sharply defined, smooth or textured surface metal parts.
 
Die Casting Advantages
Die casting can have significant advantages over other manufacturing processes, which often lead to major cost savings, not only in the part price itself but also in the overall cost of production. When you cast apart, you can create complex net shapes, including external threads and complex internal features with minimal draft angles—minimizing secondary operations. You can also combine multiple parts into a single part, eliminating assembly operations and lowering labor costs, with the added benefits of simplified stock control and greater component consistency.

We have listed the advantages of die casting, check below.
​
What is die casting advantage?

1.  Save overall production costs
2. Can create complex shapes to minimizing secondary operations
3. Variable wall thicknesses
4. Tighter tolerances, maintain casting standard and dimensional consistency
5. Fewer steps from raw material to finished part eliminates labor costs in assembly technology
6. Fast production cycle times
7. Reduction in material scrap
8. Simplified inventory control
9. Long tool life, especially for zinc and magnesium
