What is Metal Casting?

Home » News » What is Metal Casting?

Metal casting is a technique that involves melting metal and pouring it into a mold. The mold can be formed out of a variety of materials, such as clay, wax, or sand. Metal casting has been around for centuries and continues to play a significant part in today’s industries. It’s one of the most popular methods for producing intricate shapes that other methods such as forging or stamping can’t.

Common Types of Metal Casting

There are a number of different types of metal casting, some of the common ones are:

Permanent Mold Casting

Permanent mold casting is commonly employed in high-volume manufacturing of small, basic metal parts with consistent wall thickness. Magnesium alloys, copper alloys, and aluminum alloys are common non-ferrous metals utilized in this procedure. Graphite molds can, nevertheless, be used to cast iron and steel. Gears and housings, pipe fittings, and various automotive and aeronautical parts such asimpellers, pistons, and wheels are all common permanent mold parts.

Pressure Casting

Another type of permanent mold casting is pressure casting, often known as low pressure casting in the manufacturing business. Rather than pouring the molten metals into the casting and letting gravity distribute the liquid through the mold, pressure casting employs air pressure to drive the metals through the gating system and into the cavity of the metal casting. High-quality manufactured pieces can be cast using this method. This method is frequently used to cast steel castings in graphite molds. Steel railroad car wheels, for example, are cast using this technology in the industry.

Slush Casting

Slush casting is a hollow part production method based on permanent mold casting. In this procedure, neither the part’s strength nor its interior geometry can be precisely regulated. This metal casting procedure is typically used to create ornamental toys and pieces, such as lamp bases and statues.

Benefits of Metal Casting

Metal casting has numerous advantages. The method is low-cost, adaptable, and may be used to make a variety of parts. Because most surplus material wouldn’t have to be cut away, metal castings produce less waste than other production techniques such as machining. Metal casting can also be a low-cost option for limited production runs because it does not require the procurement of expensive machine tools.

Significance of Metal Casting

Metal casting is used in a variety of sectors due to its versatility and low cost.

  • The automotive industry regularly employs the method since it is inexpensive and relatively simple to make parts such as engine parts and cylinder heads with it.
  • Metal castings are also used in the medical field to make products such as surgical implants and dental crowns, as well as minor metal objects like gears and fasteners.
  • Metal casting plays a vital role in the aircraft sector because smaller parts may be made with a significant level of intricacy.
  • Other common uses for the method include the creation of artworks and musical instruments due to the ease with which precise reproductions may be created using molds.
