Q

PPO Post-Annealing Deformation

A

PPO annealing is a necessary means of stress management but must be standardized; clamping and fixing balances release and shape; temperature gradient control avoids thermal shock.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

PPO Cross-Contamination

A

PPO cleanliness management extends to the storage and conveying links; dedicated tools are low-cost mistake-proofing; the cost of cross-contamination far exceeds the management cost.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

Floating fibers of glass fiber reinforced PPO

A

For floating fiber treatment of PPO high-fiber reinforcement, speed is the key variable; both too fast and too slow cause problems; venting and temperature must cooperate to obtain a uniform surface.; after confirming effectiveness, solidify the parameters and practices into the work instruction ...
