Foundry - Classification of Castings
Foundry - Castings are classified as follows: sand castings, continuous casting, die casting, low pressure casting, centrifugal casting, gravity die casting, vacuum die casting, squeeze casting, lost foam casting.
(1) Foundry - Sand Castings
Sand casting: A casting method that uses sand to make castings. Sand mold casting can obtain steel, iron, and most non-ferrous alloy castings.
(2) Foundry - Continuous Casting
Continuous casting: An advanced casting method. The principle is to continuously inject molten metal into a special metal mold called a 'mold', while the solidified (crusted) casting is continuously pulled out from the other end of the mold. It can obtain castings of any length or specified length.
(3) Foundry - Die Casting
Die casting: Molten metal is injected into a metal cavity at high speed under high pressure, and the casting is formed by cooling and solidifying under pressure.
(4) Foundry - Low Pressure Casting
Low-pressure casting: Refers to a method in which liquid metal is filled into a mold under low pressure (0.02~0.06mpa) and crystallized under pressure to form a casting. Scope of application: mainly traditional products (cylinder heads, hubs, oil cylinder brackets, etc.).
(5) Foundry - Centrifugal Casting
Centrifugal casting: A casting process in which molten metal is poured into a rotating mold, and the mold is solidified by centrifugal force.
Centrifugal casting was first used in the production of cast pipes and is used in the metallurgy, mining, transportation, irrigation and drainage machinery, aviation, national defense, automobile and other industries at home and abroad to produce steel, iron and non-ferrous carbon alloy castings. Among them, centrifugal cast iron pipes, internal combustion engine cylinder liners, and bushings are common castings.
(6) Foundry - Gravity Die Casting
Die casting: Refers to a casting molding method in which liquid metal fills a metal mold under the action of gravity and is cooled and solidified in the mold.
(7) Foundry - Vacuum Die Casting (Vacuum Die Casting)
Vacuum die casting: An advanced die casting process that improves the mechanical properties and surface quality of die castings by eliminating or significantly reducing air in the die casting cavity.
(8) Foundry - Squeeze Die Casting
Squeeze casting: A method of solidifying and flowing liquid or semi-solid metal under high pressure to directly obtain products or blanks. It has the advantages of high utilization rate of liquid metal, simple process, and stable quality. This is an energy-saving metal forming technology with potential application prospects.
(9) Foundry - Lost Foam Casting
Lost foam casting (also known as full mold casting) is a new type of casting method. It combines paraffin or foam models similar to the size and shape of the casting into clusters, brushes them with fireproof paint and dries them, and then embeds them in dry quartz sand for vibration molding. Casting under negative pressure causes the model to vaporize, and the liquid metal positions the model to form a solidified casting after cooling. Scope of application: Suitable for the production of various complex castings, alloy types and production batches are not limited. Such as gray cast iron machine boxes, high manganese steel elbows, etc.
