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.
