PPO Extruded Product Line
Problem Phenomenon
[Problem Phenomenon] What products PPO extrusion can make, the process capability evaluation is insufficient
Cause Analysis
PPO extrusion can produce rods, tubes, sheets and wire coating; EN212/EN265 extrusion grades (UL94 V-1) are suitable for structural components of electrical, electronic, chemical and machinery applications
Solution
Select extrusion grades for extruded products; evaluate the temperature resistance rating for wire and cable coating; utilize dimensional stability for subsequent '2079851475616104458 of sheets; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PPO extrusion ranges from rods, tubes and sheets to cable coating, and the EN series is the main force of extrusion; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
