  Baozhu sand is new casting sand developed by our engineers and technicians based on more than ten years rescarch and experiment. The achievement is appraised by foundry experts as a revolution in casting sand.

  Baozhu sand has good heat-resistance, low heat expansion, desirable collapsibility and good reusability; it doesn,t break during process and has good foundry characters, Now, It is used in all types of casting method like sand casting, investment casting. It ia also applicable to sand blasting, resin sand manufacturing, and suitable for all binders.

  Because of its pptimum combibination of cost and foundry characters, with it,s rapid growing in recent years, Baozhu sand is widely used in sll linds of ferrous snd no-ferrous metal casting as a best substitute of chromite sand.

  As the inventor of Baozhu sand, we are vety proud that it has been exported to Japan,France, South Kouth and other countries, where it,s called as “Green Bead”.
