Q

Improper PESU Mold Temperature

A

The 149~163℃ of PESU mold temperature is the supplier standard; uniformity ensures consistency; balance optimization is based on verification.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

PESU Melt Temperature Too High Degradation

A

PESU's 385℃ upper limit is the degradation red line; color management of transparent parts is stricter; actual temperature measurement prevents gauge display errors.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

PESU Insufficient Drying Temperature and Time

A

The 135℃ lower limit of PESU drying is an efficiency guarantee; not allowing over-drying is a material characteristic; the influence of ambient humidity must be compensated.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

PESU Insufficient Drying Surface Streaks

A

PESU drying is the prerequisite for appearance quality; 500ppm/100ppm are different standards for '2079851475616104452/extrusion; the ability to recycle, dry, and reuse defective parts is a material advantage.

Q

PEI Equipment Maintenance Plan

A

PEI equipment maintenance should be tightened according to high-temperature working conditions; life management prevents sudden failures; record analysis optimizes plans.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Processing Machinery PEI;equipment maintenance;high temperature;life;spare parts;record

Q

PEI Process Window Fixation

A

PEI process stability relies on discipline; change management is a system requirement; audits ensure execution.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Processing Machinery PEI;process window;fixation;change;discipline;audit

Q

PEI Supplier Technical Documents

A

The authoritative source of PEI process parameters is the supplier manual; version management prevents expiration; technical support channels are smooth.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
