What is the difference between die casting and casting?
1. The definitions of die casting and casting are different:
Die casting is a metal casting process characterized by applying high pressure to the molten metal in the inner cavity of the mold. The mold is usually made of a higher strength alloy. This process is somewhat similar to injection molding.
Casting is a method of pouring liquid metal into a casting cavity that is adapted to the shape of the part, and waiting for it to cool and solidify to obtain parts or blanks.
2. The processes of die casting and casting are different:
The essence of pressure casting (referred to as die casting) is to fill the die casting mold cavity with liquid or semi-liquid metal at a high speed under high pressure, and to form and solidify under pressure to obtain castings.
The casting process can be divided into three basic parts, namely casting metal preparation, casting mold preparation and casting processing. Casting metal refers to the metal material used for casting castings in casting production. It is an alloy composed of a metal element as the main component and other metals or non-metallic elements. It is usually called a casting alloy, mainly cast iron, cast steel and casting non-ferrous alloys.
3. The casting accuracy of die casting and casting is different. Die casting is a precision casting method. The dimensional tolerance of die castings cast by die casting is very small and the surface accuracy is very high. In most cases, die castings can be assembled and applied without turning, and threaded parts can also be cast directly. Casting, melting metal, making castings, and pouring molten metal into the castings. After solidification, a metal part blank with a certain shape, size and performance is obtained.
