PEI '2079851475616104458 Process
Problem Phenomenon
In PEI '2079851475616104458 applications such as catheters, uneven thickness and unstable dimensions occur; the '2079851475616104458 window is narrow.
Cause Analysis
PEI can be thermoformed for catheter applications; heating temperature and uniformity control; influence of material internal stress; cooling and setting management.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
①'2079851475616104458 temperature according to material specifications; ②heating uniformity assurance; ③selection of low-stress sheets; ④dimensional setting verification.; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
PEI '2079851475616104458 is a special application; temperature uniformity determines quality; sheet condition is the foundation.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
