Low Gas

Anti Sand Fusion

Easy Shake Out

High Strength and Good Flowability

While most Indian manufacturers use liquid resin and semi-hot method of mixing, AMM uses solid phenolic resin, developed by AYC Japan, and dry-hot way of mixing. This enables AMM to offer resin coated sand with better heat resistance, higher strength & lower gas evolution.

AMM has been successfully developing and customizing resin-coated sand offerings to meet the requirements of its customers. Unlike other Indian manufacturers who simply increase or decrease the percentage of resin in the product, AMM uses different kinds of solid phenolic resins developed by AYC Japan.

 

AMM’s resin coated sand is being continuously developed and improved for zero defects in castings. Some of the problems faced by Indian casting manufacturers are:

 

  • Gas defects (Pin hole, blow holes)
  • Surface finish
  • Veining
  • Core/mold unfilling
  • Core-mold breakage due to low strength
  • Sand fusion
  • Collapsibility or shake-out at the time of decoring
  • Strength and many more

 

Higher efficiency and better productivity for customers:

 

Due to the usage of solid phenolic resins and high quality washed silica sand, we are able to achieve better flow, lesser curing time and better strength. This results in fewer rejections. Moreover, surface coating of molds/cores can be eliminated and is proven to be cost-efficient as it helps in eliminating costs associated with coating, baking and lowered rejection rate, and hence lowers the cost of production for users. Therefore, users get a better output.
