can i elevate the drying température or add more time for drying process .
thank you so much
RE: polyamide Nylon 6 injection problem
If still foaming, continue drying. I would suggest you dry for at least 8hrs until you know your dryer performance - if it's just a hot air dryer, I would strongly recommend you invest in either a dessicant or vacuum dryer. You'll soon repay your investment cost.
In a vacuum dryer, temp can be increased to 100°C - needs a vacuum to prevent surface oxidation.
NOTE: Even without showing foaming, moisture content can be too excessive causing brittle mouldings which look fine.
