Injection Molding

Drying is recommended, but not necessary for newly opened packaging stored in a dry location.

Follow the drying guidelines above in the following cases

  • If moisture is above the Processing Moisture Content recommendation,
  • When a resin container is damaged,
  • When the material is not properly stored in a dry place at room temperature, or
  • When packaging stays open for a significant time.
