OUR GREEN SAND CASTING PRODUCTION PROCESS

A multi-step process that produces near-net shape precision casting parts. The process begins with the creation of patterns. These are then used to create moulds that are filled with molten metal to create the part. Secondary processing, such as machining, welding or painting can also be done. The process uses different machines such as furnace, injection, blasting, tumbling, cutting, grinding, etc. The process involves mainly the following steps

  • 1. Pattern Design
    Designing patterns is a complex process that requires very specific know-how.
  • 2. Pattern Making
    Patterns made of wood, resin (plastic) or aluminium could be used to produce during the casting
  • 3. Molding Process
    Moulds are created with sand that is pressed using the pattern to create the desired shape
  • 4. Melting
    Electrical furnaces are used to melt iron from scrap and the necessary alloys or additional components needed to achieve the desired final standard
  • 5. Pouring and solification
    Liquid steel is then poured into the moulds and left until it solidifies.
  • 6. Shake-Out and Cutting
    Once the metal has solidified and cooled down to the required temperature, the castings are removed from the sand mould by vibration. Then, each individual part is separated by knocking off or cutting
  • 7. Shot Blasting and Finishing Processing
    The parts are shot blasted to fully remove sand and oxides. The casting part is then fully customized through finishing processes: grinding, heat treatments, machining, component welding, et al
  • 8. Testing, Packing and Delivery
    Then the casting parts will be fully tested for the dimensions, surface, mechanical properties and other required tests before packing and delivery

WANT TO KNOW MORE OF GREEN SAND CASTING

A highly flexible process that can be used for high volume, fully automated casting or for very low number of parts. Sand, bound with clay and water, is used to make moulds around a pattern made of metal, wood or resin. Metal is poured into the mould and once solidified, the sand can be re-used over and over again making greensand casting one of the most cost effective and environmentally friendly of all the casting processes.

Clay-bonded sands have provided the principal medium from which molds for castings have been produced for centuries. In essence the mold material consists of sand, usually silica in the quartz form, clay and water. The water develops the bonding characteristics of the clay, which binds the sand grains together. Under the application of pressure, the mold material can be compacted around a pattern to produce a mold having sufficient rigidity to enable metal to be poured into it to produce a casting. When the mold is used in its moist condition it is referred to as green and the method of producing the molds as the green sand molding process.
