Iron Casting
iron casting : most recognized casting technology
Iron casting plays a very important role in mechanical engineering nowadays, and many metal parts with complex structures that need to have load-bearing capacity choose to rely on iron casting technology. Similar to steel casting, molten iron is injected into a mold for cooling and forming, resulting in the final iron cast part we need.
With high efficiency and cost effectiveness, iron cast parts are used in a wide variety of industries for a variety of applications. With quality heat treatment and surface treatment, iron castings can have excellent corrosion resistance and high strength.
Supro metal foundry is committed to providing first-class cast iron parts
Supro metal foundry is a top iron casting foundry in China, passed ISO9001-2015 quality system, with advanced automated wet sand model and laminated sand mold manufacturing equipment, can handle a wide range of complex iron castings from 0.5kg-2000kg, professional mold design and manufacturing expert team, can provide for a variety of complex structure Solutions, we have professional casting capacity to handle malleable cast iron, gray cast iron, ductile iron and other materials, which are widely used in: construction engineering, agriculture, automotive, railroad transportation, manufacturing, urban infrastructure and other fields.
Custom Iron casting parts
grey iron casting parts
Due to its low cost and machinability, gray cast iron is often used as an engineering alloy for applications such as machine tool mounting, manhole covers, and counterweights.
ductile iron casting parts
It is easy to machine, has good fatigue and yield strengths, and is also wear resistant. However, its best known characteristic is ductility. Ductile iron is used in the manufacture of steering joints, plow heads, crankshafts, heavy gears, car and truck suspension components, hydraulic components and automotive door hinges.
Malleable iron casting parts
Attractive properties of malleable cast iron are its ability to retain and store lubricants, non-abrasive wear particles, and porous surfaces that trap other abrasive debris. Malleable cast iron is used for heavy bearing surfaces, chains, sprockets, connecting rods, driveline and axle components, railroad rolling stock, and agricultural and construction machinery.

iron Shell mould casting
relying on resin sand or green sand to form a cavity with the shape of the final product under the action of aluminum or steel molds, inject molten metal into the sand mold, and cool to form. Aluminum alloy sand casting is economical, but usually requires secondary machining to achieve close dimensional tolerances, and is also very effective for creating large aluminum alloy cast parts or parts with fine detail, suitable for large-scale casting projects.
At Supro casting foundry, we control the casting process and the element composition of the aluminum alloy reasonably to avoid most of the defect problems, enhance the mechanical properties, improve the casting efficiency, and make the aluminum alloy castings more competitive.
Advantages: high efficiency, low cost, economical, complex structure can be realized, suitable for a wide range of materials
Disadvantages: There are many sand holes and pores, and the surface is rough. It is impossible to build fine details.
Iron Resin sand casting
Creates steel molds and other metal molds or cores. The molten aluminum alloy is cooled and formed inside the mold. This is a reusable metal mold. More often, the aluminum alloy is injected by gravity to fill the mold cavity. Inside. The mold is then separated after cooling and the finished part is ejected or removed.
Supro MFG uses this rapid prototyping casting process to achieve a more consistent microscopic metal structure, increase the density of aluminum alloy castings, and significantly enhance the mechanical properties of the product. It is generally used in industries with high weighing capacity, wear resistance, and corrosion resistance. in demand.
Advantages: Higher product density Fast build time Low product cost High surface finish Finer detailing possible
Disadvantages: High mold cost Does not support design changes Not suitable for large castings Long mold manufacturing cycle
iron casting parts have excellent mechanical properties
- Hardness – the material’s wear resistance and indentability
- Toughness – the ability of the material to absorb energy
- Ductility – the ability of a material to deform without fracture
- Elasticity – the ability of a material to recover its original dimensions after deformation
- Ductility – the ability of a material to deform under compression without breaking
- Tensile strength – the maximum longitudinal stress that a material can withstand without tearing
- Fatigue strength – the highest stress a material can withstand in a given number of cycles without fracture
