Application of Six Sigma Method to Reduce Defects in

process improvement that relies on statistical & scientific methods to reduce the defect rates and achieve significant quality up- gradation [1]. Green sand casting gives enough green strength to get dimensional stability and provides excellent surface finish and better collapsibility during the knockout. Choosing Between Nobake and Green Sand Metal Casting Size and shape-wise, the green sand casting process has almost no limit. Typical green sand castings range from several ounces to 500 lbs., but green sand castings as large as 7,000 lbs. have been made. Nobakes size range is similar to green sand, but it is often the process of choice for very large castings weighing more than 100,000 lbs

Green Sand Casting. A highly flexible process, greensand casting 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 Introduction to Greensand Casting - The Eagle Group

  • The Greensand Casting Process
      The advantages and disadvantages of green sand casting The green sand casting process can achieve high production rate. The floor molding with green sand can produce castings of 100 to 200 sand boxes each day, e.g. about 100 pieces to 2000 pieces each day. The automatic molding process with green sand can produce castings of 20 tons each day. Sand Casting Green Sand vs Resin Sand Casting OTTOMMOResin Sand Molding Process. We also call this process as resin-bonded sand molding method. Because of the resin-bonded sand, the sand mold is harder than green sand molding. Additional burning of coated sand will make the sand mold solid. This creates a good surface and tight tolerance for the casting.
