Q

POM Injection Pressure Grading

A

POM pressure setting must be graded by structure; the wide range of 40-140MPa means one-size-fits-all parameters will inevitably sacrifice one aspect for another; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Q

POM Pressure Sensitivity for Flow Adjustment

A

The correct means of adjusting POM flow is pressure, not temperature; the temperature-raising route is a typical wrong direction for POM; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
