Caution
- Drying
- Hygroscopic materials will cause drooling, deterioration of physical properties, and poor appearance.
- We recommend using a dehumidifier or vacuum dryer because using a hot air dryer may not result in sufficient dryness in case the surrounding humidity is high.
- For improved repletion, please make sure enough air vents are fabricated.
- Purging
- When molding is interrupted for 5 minutes, please purge for at least three shots.
- When molding is interrupted for 30 minutes, or when molding is completed, immediately replace the resin inside of the cylinder with high-density polyethylene or polypropylene.
- When replacing resin, please use commercially available purge materials (Asaclean New-Ex, Celpurge NX-HG, TADAZO 200H etc.) or high-viscosity PE or PP.
