PVC Welding Assembly
문제 현상
PVC parts showed insufficient welding strength, weld leakage, or discoloration and degradation at the weld
원인 분석
PVC can be hot-air welded and solvent bonded; improper welding temperature control causes degradation and discoloration; coating uniformity of solvent bonding determines sealing reliability; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
해결 방법
①Precisely control hot-air welding temperature to prevent degradation; ②apply solvent bonding uniformly and cure fully; ③post-weld sealing test; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
핵심 요약
PVC welding has two routes: heat and solvent; their quality points differ but neither can exceed the temperature limit; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
