The sand casting is the simplest production method but has many advantages, particularly for short-run or complex castings with multiple cores or for larger castings. We are able to produce sand moulds by hand, using greensand for smaller quantities and resin or petro bonded techniques using a semi- automated process for larger quantities.
Ningbo Suijin provides superior quality sand casting parts and components to industries including automotive, transportation, mining, petrochemical, electrical, energy and others. Materials can be aluminum alloy, ductile iron, brass alloy, gray iron etc. We offer high precision CNC machining and other secondary operations. We also offer rapid prototype services. Both low to high-production volume sand casting are welcome.
Almost any ferrous and non-ferrous metals can be casted by sand casting
Parts caan vary greatly in size, weight and shape. Weight can be from ounces to hundreds of tons
Cost of tools is low comparing to other process
Small quantity or large quantity
Relative low cost for high volume parts
A wood, resin or metal pattern is made which forms an impression of the component to be cast.
The pattern is used to make a mould, usually in greensand or resin bonded sand.
If cores are required to form internal structures, these are made in CO2 or resin sand.
Molten metal is poured into the mould, which is then allowed to solidify.
The casting is then removed from the mould and up to 70% of the sand is reclaimed.
The casting then goes through the fettling process to remove the risers and excess material
Castings often undergo further surface finishing before dispatch to the customer
Limitations of the process
Materials can be aluminum alloy, ductile iron, brass alloy, gray iron etc.
Grinding, drilling, tapping, painting, shot blasting
Assembly, packaging
High precision machining
Heat treatment
