Q

PCABS back pressure adjustment

A

The step adjustment and observation cycles of PCABS back pressure are fine craftsmanship; shear heat management protects the material; monitoring prevents degradation.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Production & Quality PCABS；back pressure；50psi；shear heat；step；observation

Q

PC Internal Bubbles

A

PC bubbles are investigated by the three-way method of 'water, vacuum, entrained air': first verify drying, then look at holding pressure, and finally check venting; transparent parts have zero tolerance for bubbles, and drying verification is the first and most important checkpoint.

Q

PBT Sprue Material Recycling

A

PBT sprue material recycling is graded by grade; the ban on recycling flame-retardant and glass fiber material is a clear discipline; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Production & Quality PBT; sprue material; recycling; flame-retardant material; glass fiber material

Q

PA6 and PA12 Selection

A

Humidity dimensional stability is the watershed between PA6 and PA12; conditioning pretreatment can alleviate it, but the premium of PA12 is worth the money in high-precision scenarios; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence

Production & Quality PA6；PA12；dimensional stability；moisture absorption expansion；selection

Q

PA6 Chemical Resistance Boundary

A

PA6's chemical resistance is a selective advantage; the boundary of oil resistance but not strong acid resistance must be confirmed item by item in the material selection review; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence

Production & Quality PA6；chemical resistance；strong acid；oxidant；material selection

Q

PA66 chemical resistance boundaries

A

PA66 chemical resistance is a selective advantage; the boundary of oil resistance but not strong acid resistance must be confirmed item by item in material selection review; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence
