PPO Control Housing Application
문제 현상
[Problem Phenomenon] Electrical control housings need heat resistance, flame retardancy and dimensional precision
원인 분석
Typical PPE applications include control housings: heat resistance, flame retardancy and dimensional stability combined; precision fit utilizes low shrinkage and low water absorption; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
해결 방법
Select flame-retardant PPO grades for control housings; design mating surfaces according to low shrinkage; select weather-resistant modification for outdoor cabinets; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
PPO is a classic material selection for electrical control housings, with both precision and flame retardancy; 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
