What is Casting?

Casting is a manufacturing process with around 6,000 years of history. During the process, a liquid such as hot metal is poured into a container, or a mould. After the metal is solidified, the resulting cast, also called a model or an object, will have the desired shape.

Casting approaches

Modern metal casting could be classified into 4 types (Figure 1). Ming Ming’s gravity casting is based on permanent mould casting.

Materials used in casting

Materials used for casting include metal, plaster, concrete, and plastic resin. Most commonly used materials in metal casting include gray iron, ductile iron, aluminium, steel, copper, and zinc. Ming Ming specialises in aluminium metal casting and provides tailor-made applications for various industries.

Mould Materials

Moulds are negative forms used for shaping casting materials.The type of mould technique depends on the complicity of the desired model and the mould can be open or closed for metal casting, the closed mould is the common form.
Depending on whether it can be repeatedly used, the mould can be expendable or long-lasting.
The long-lasting mould can be used to create many metal objects and is often made of metals or a refractory ceramic.
In gravity casting,moulds are often made of metal or Graphite. Ming Ming’s gravity casting process uses non-expendable or long-lasting moulds and produces objects using only metal moulds coated with a mould wash.
