Ductile Cast Iron Parts Manufacturers

Forgings can be divided into cold forging, warm forging and hot forging according to the temperature of the blank during processing. Cold forging is generally processed at room temperature, and hot forging is processed at a temperature higher than the recrystallization temperature of the metal blank. 

Metal forging is a manufacturing method that involves shaping metal using compressive force with a hammer, press or other equipment. Depending on the metal being forged and the desired output, this procedure can be carried out at various temperatures.

The size accuracy of the coating sand casting casting is CT7 ~ CT8, and the surface roughness RA value is 6.3 to 12.5 m. The formation of the forming sand of the membrane can reach the level of water glass melting mold casting process.

Maple always use a new material for the blades of replicas (swords, paratschwerts, rapiers, sabers, tusks…), because there is higher danger of hidden inner defects in the old material.

Cylinder forgings are widely used in port machinery, fire protection, coal mines, thermal engineering, decarbonization and other fields. They are a type of forgings favored by customers. They have high material utilization rate, high dimensional accuracy, high comprehensive mechanical properties and fine structure, the fiber structure is reasonable, it is one of the more common forgings, it is formed by extrusion at high temperature, or by hammering and other methods, and it has multiple functions such as steel rolling equipment.

Materials used in forging are mainly carbon steel and alloy steel of various components, followed by aluminium, magnesium, copper, titanium and their alloys. The original states of materials are bar, ingot, metal powder and liquid metal. The ratio of the cross-sectional area of metal before deformation to that after deformation is called forging ratio.
