PC Automotive Parts Applications
Problem Phenomenon
[Problem Phenomenon] Automotive parts require high impact resistance, heat resistance and dimensional stability
Cause Analysis
PC is used for automotive sunroofs, instrument panel components, sensor housings and charging piles; high impact resistance, heat resistance and dimensional stability; when troubleshooting on site, verify each item according to this mechanism one by one, and avoid blindly adjusting the machine based on experience alone
Solution
Select heat-resistant or glass fiber PC for automotive parts; coating for weather-resistant parts; flame retardant grades for charging piles; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes, so as to locate effective measures
Key Takeaway
PC automotive parts are impact resistant and heat resistant, from sunroofs to charging piles; 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
