Know all about casting technology in one article

Today, I will share a dry casting process and learn about a variety of casting types.

What is casting?

Liquid metal is poured into the mold cavity suitable for the shape and size of the part, and cooled and solidified to obtain a blank or part, which is usually called liquid metal forming or casting.

Sand casting: casting method for producing castings in sand mold. Steel, iron and most nonferrous alloy castings can be obtained by sand casting. Used in automobile engine cylinder block, cylinder head, crankshaft and other castings. Investment casting is applied to the production of small parts with complex shapes, high precision requirements or difficult other processing, such as blades of turbine engines. Pressure casting, application: Die casting was first used in automobile industry and instrument industry, and then gradually expanded to various industries, such as agricultural machinery, machine tool industry, electronics industry, national defense industry, computers, medical devices, clocks, cameras and daily hardware. Low pressure casting, used in: mainly traditional products (cylinder head, wheel hub, cylinder frame, etc.) Centrifugal casting, application: centrifugal casting was first used to produce cast pipes, and centrifugal casting technology was used to produce steel, iron and non-iron carbon alloy castings in metallurgy, mining, transportation, irrigation and drainage machinery, aviation, national defense, automobile and other industries at home and abroad. Among them, centrifugal cast iron pipe, cylinder liner and shaft sleeve of internal combustion engine are the most common castings. Metal mold casting is applied to: metal mold casting is suitable for mass production of non-ferrous alloy castings such as aluminum alloy and magnesium alloy with complex shapes, and also suitable for the production of steel and metal castings and ingots. Squeeze casting can be used to produce various types of alloys, such as aluminum alloy, zinc alloy, copper alloy and ductile iron. Lost foam casting is applied to: it is suitable for producing various precision castings with complex structure, and there is no limit on alloy types and production batch. Such as gray cast iron engine box, high manganese steel elbow, etc. Continuous casting is applied to: long castings with constant cross-section shapes such as steel, iron, copper alloy, aluminum alloy and magnesium alloy can be poured by continuous casting, such as ingots, slabs, bars and tubes.
