Q

PA6 Glass Fiber Reinforced Warpage

A

The essence of glass fiber PA6 warpage is orientation anisotropy; gate design and uniform-temperature cooling are the source countermeasures, and the shaping fixture is an effective remedy; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent ...

Q

PA6 Low-Viscosity Drooling and Flash

A

The low viscosity of PA6 is a double-edged sword; drooling prevention relies on the needle-valve nozzle, flash prevention relies on pressure control and mold precision, both ends must be blocked; after confirming effectiveness, solidify the parameters and practices into the work instruction to pr...

Q

PA6 Shrinkage and Post-Shrinkage

A

PA6 dimension management must account for both the shrinkage bill and the water absorption bill; conditioning pretreatment plus post-equilibrium inspection is the only way to lock dimensions in the service state; after confirming effectiveness, solidify the parameters and practices into the work ...

Q

PA6 and PA66 Selection

A

PA6 and PA66 processes cannot be borrowed from each other; temperature rating and cost are the two dimensions of selection, and changing material must change the entire set of process parameters; after confirming effectiveness, fix the parameters and practices into the work instructions to preven...

Q

PA6 Uneven Mold Temperature Countermeasures

A

Mold temperature uniformity affects dimensional stability more than the absolute mold temperature value; check the water circuits first and then adjust the temperature; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence
