No-bake \ Airset Foundry

Frequently Asked Questions

What is a no-bake foundry?

A no-bake foundry uses dry sand that contains a quick-setting liquid resin and catalyst to form molds. The molding sand is poured into the flask and held until the resin solidifies, which occurs at room temperature. Because no heat is involved it is called a cold-setting process. The no-bake process is primarily used for low to medium volume work.

The nobake process provides the following advantages:

  • Ability to use wood and plastic materials for patterns and core boxes, which are less expensive than metal patterns required for other processes
  • Good casting dimensional tolerances
  • good casting finishes
  • Castings are easily removed from the molds (shakeout)>/li>
  • Molds and cores can be stored for long periods of time
