What's the Difference Between Molding and Casting?

1. What's the difference between molding and casting?


Casting is the manufacturing process of introducing molten material into a solid mold and curing it. The term usually refers to metals, but it also applies to the same process for other materials. Ceramics can be cast in a sliding mold, and polymers can also be cast.


Molding is the molding of a soft but not completely liquid material (eg., the moist clay). Molding can also use molds to form soft materials, but it's unnecessary to use this kind of mould.


The basic difference is the way the material is poured into the mold. During the molding process, it will be poured under pressure. In addition, in most casting processes, because molten material has a very low viscosity and flows only under gravity, it can be poured without any external force.


During the molding process, the output is the final precision mold components. However, in most casting processes, the output is the unfinished part that needs to be finalized (processed).


2. What is injection molding?


Injection molding is a molding process using a mold. A material such as a synthetic resin (plastic) is heated and melted, and it will be sent to the molds to cool and formed as the designed shape. The process is called injection molding because it is similar to injecting fluid with a syringe. The flow of the process is as follows: the material is melted and poured into a mold to harden it, and the molded product is taken out and finished.


Being molding by injection molding China, it is possible to continuously and rapidly produce mass and various shapes of parts, including precision mold parts with complex shapes. Therefore, injection molding is widely used in the manufacturing industry molding products.


3. What are die casting products?


Die casting is one of the most economical and fastest forming processes. The advantage of this process is that thousands of die castings can be produced relatively quickly using a single die. All components produced are of uniform quality and involve relatively low unit costs.


Die casting is an automatic casting process, and the liquid melt is pressed into the mold under high pressure (150-1200 bar) and high filling speed (a maximum of 540km/h). Die casting suppliers usually use alloys with low melting points. The casting process is especially suitable for mass production and mass production of parts because it's different from sand casting. For example, permanent metal molds are used and don't have to be destroyed after casting. It is possible to produce large and complex parts with very thin wall thickness.
