  • Product Name：Precoated Sand/Resin coated sand
  • Model：ZS
  • Product Category：Coated Sand
  • Application：Resin coated sand, which also called precoated sand/shell sand, is new developed sand molding materials that used for making various sand cores or molds for casting in foundry plants. It has advantage of high strength of sand mold and easy to do sand cleaning. By using hot box sand core shooters or automatic molding machine, it has high work efficiency and low requirement of master workers. So it is widely used for large quantity of casting parts production, like pump, motor, truck hub, engine cylinder, auto metal parts, brake disc, sanitary hardware, meter, lock, etc.
Product Description



Advantage of resin coated sand:

1) It has suitable strength that can manufacture both high strength and low strength coated sand.

2) It has good fluidity that can manufacture complex sand cores.

3) The surface quality of sand core is in high quality that it can use less coating or without coating.

4) It has good collapsibility that the casting is easy to clean up.

5) The sand core has good hygroscopicity that can be stored in a long time and conveniently to transport.

6) Resin coated sand can be applied as commodity that offer convenience for customers.

Considerations:
    1、Sealed, moisture-proof, stored in a cool dry place.
    2、Stacked not more than three layers, prevent caking.
    3、After slightly caking crushed can still be used.
    4、Core shooter pressure: 0.3-0.5mPa, curing temperature: 220-300℃.
