TPE Barrel Zone Temperature
문제 현상
Uneven plasticization and cloud marks on products, or nozzle drooling and cold material spots on products
원인 분석
TPE barrel zoning: rear zone 160-180℃, middle zone 170-200℃, front zone 180-220℃; nozzle temperature is independently controlled; improper zoning causes uneven plasticization or drooling
해결 방법
①Barrel rear zone 160-180℃, middle zone 170-200℃, front zone 180-220℃; ②Nozzle temperature slightly lower than the front zone; ③Cold slug well setting
핵심 요약
TPE barrel zoning is the basis of uniform plasticization; the three-zone gradient plus independent nozzle temperature control, neither can be omitted; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
