Types of Metal Casting
Sand Casting
Sand casting is a metal casting process that uses sand as the modeling material. Liquid metal is poured into the sand casting cavity, and after it cools and solidifies, a casting with a certain shape and performance is obtained.
Investment Casting
Investment casting also known as lost-wax casting was created 5000 years ago. This kind of casting method provides accurate, repeatable, and versatile parts with different metal and high-performance alloys.
Die Casting
Die casting is a type of metal casting process. It creates a mold cavity with two hardened tool steel dies, and shapes the metal under a high-pressure, pour the metal into a mold cavity.
Shell Casting
Shell casting has finer mold material which is made of the hardened shell of sand rather a flask filled with sand. Mixed this kind of mold material with resin, so the mold cavity it created is more smooth and can be quickly heated.
Centrifugal Casting
It is a casting method in which liquid metal is poured into a rotating mold, which fills the mold and solidifies under the action of centrifugal force. The mold is first preheated, and then the molten metal is poured into the high-speed rotating mold.
Heavy Metal Casting
Heavy metal casting refers to the use of density greater than 5 of the metal (such as copper, lead, zinc, nickel, etc.), through a specific casting process, will be melted into a liquid metal to meet the requirements, and poured into the casting mold, after cooling and solidification, finishing treatment to obtain a predetermined shape, size and performance of the casting process.

Application of Metal Casting
Motor Casting: The automobile depends on metal castings, from the engine to the brakes using ferrous, non ferrous metals and its alloys. Zinc die casting and aluminum die casting are some of the well known methods for casting automobile components.
Air Craft Casting: Metal casting applications are favoured by the air craft sector both in for miliatary and civilian purpose. The advanvantage is that casting helps to save thousands of dollars than what would have been spent on forging the aircraft components.
Weapon Casting: One of the primary applications was for casting weapons for hunting and protection. The earliest proof of weapon casting is the casted copper axe head that was unearthed with the oldest naturally mummified of 3300 B.C.
Bell Casting: The rhythmicall thronging of the bells never loses its charms and so is the traditional methods of castig bells. Though the bell are not used on a large scale, there are many foundries that specialize in casting bells.
Strand Casting: This is the process of casting the metal into a continuous strand which can be rolled in a convenient manner. These semi finishedshapes that are largely casted in the form of blooms, billets, plates, strips etc. helps in saving time, capital, and energy.
As one of the most professional metal casting manufacturers and suppliers in China, we're featured by cheap products and good service. Please rest assured to wholesale custom made metal casting at competitive price from our factory.
