PA66 drying 0.2% red line

0.2% is the PA66 moisture content red line; hydrolysis damage is irreversible, drying, drying, and more drying is the golden rule of PA66 processing; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Material Drying PA66; drying; 0.2%; hydrolysis; vacuum drying; 105℃

PA66 product low welding strength

PA66 welding='state unification': moisture is the chief culprit of cold welds; nylon welding must standardize the moisture state for parameters to be meaningful; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.

PA66 product drop fracture

PA66 drop='path analysis': check where it breaks; weld lines, sharp corners and dry-state brittleness are the three high-incidence areas; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.

PA66 product corner chipping and edge breakage

PA66 corner chipping='sharp corner + dry state': rounded corners and conditioning on both fronts; nylon is brittle in dry state, sharp corners are the starting point of fracture; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.

PA66 product conditioning

PA66 'condition first, then assemble': dry-state nylon is a time bomb; conditioning is a basic skill of nylon product factories and cannot be omitted; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.

PA66 water absorption dimensional change

PA66 precision parts 'must define dry/wet state': water absorption expansion is its nature; design by wet state, measure after conditioning, otherwise dimensions will never match; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.

PA66 bubbles

PA66 bubbles follow the 'water, vacuum, decomposition' three-way classification: moisture is the primary cause in high-temperature nylon; drying verification comes first, holding pressure and temperature control follow; after confirming effectiveness, fix the parameters and practices into the wor...

PA66 hydrolysis strength deterioration

PA66 hydrolysis='invisible performance killer': normal appearance does not mean qualified; high-temperature nylon hydrolyzes faster and more covertly, moisture content verification and time-limited use are life-saving measures.

Silver streaks from insufficient PA66 drying

PA66 drying standard is 'stricter than PA6': control moisture content toward the low end; high-temperature processed PA66 has zero tolerance for moisture, and drying verification must be a hard prerequisite for startup.
