PSU Vacuum Metallization High-Gloss Appearance
Problem Phenomenon
【Problem Phenomenon】Heat-resistant parts requiring high-gloss mirror appearance, metal weight and cost are unacceptable
Cause Analysis
PSU/PESU can be vacuum metallized to obtain a high-gloss mirror effect, and heat resistance far exceeds plating-grade ABS/PC; lighting and reflective parts are typical applications
Solution
Use PSU/PESU vacuum metallization solutions for high-gloss heat-resistant parts; anneal before plating to ensure adhesion; verify coating durability by thermal cycling; after adjustment, continuously sample to verify the effect, confirm stability before resuming mass production
Key Takeaway
Vacuum metallization gives PSU a mirror appearance, and its heat-resistant foundation far exceeds ordinary plastics; after confirming effectiveness, fix 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
