ASA and PC Alloy Application
Problem Phenomenon
【Problem Phenomenon】Need ASA weather resistance and PC's high heat resistance and impact resistance, a single material is not enough
Cause Analysis
PC/ASA alloy combines PC's high heat resistance and impact resistance with ASA's weather resistance, suitable for automotive and outdoor high-performance parts; blending ratio determines performance emphasis; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based only on experience
Solution
High-requirement outdoor parts evaluate PC/ASA alloy; adjust blending ratio according to heat resistance and weather resistance needs; processing temperature raised on the PC side; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
PC/ASA alloy is a high-end combination of weather resistance plus heat resistance; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
