Description

사출성형기용 히터
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명을 사출성형기의 사출노줄에 적용한 일시예를 표시한 종단면도.
제2도는 제1도의 실시예에 있어서 절연 세라믹의 외피를 제거하고 도전성 세라믹의 피막을 표출한 외관을 표시한 사시도.
제3도는 도전성 세라믹 피막을 세로방향의 줄무늬 모양으로 형성한 실시예에 있어서 절연 세라믹 외피를 제거한 외관을 표시한 사시도.

Claims (5)

  1. 가열 실린더 혹은 사출노줄 등의 피가열부의 외주면에 용사에 의해 도전성 세라믹 피막을 형성한 것을 특징으로 하는 용융수지를 금형내에 사출하여 성형하는 사출성기용 히터.
  2. 도전성 세라믹 피막을 세로방향의 줄무늬 형상으로 형성한 것을 특징으로 하는 특허청구의 범위 제1항기재의 사출성형기용 히터.
  3. 도전성 세라믹 피막을 나선상으로 형성한 것을 특징으로 하는 특허청구의 범위 제1항 기재의 사출성형기용 히터.
  4. 사출노즐의 외주면을 전후로 둘로 나누어진 도전성 세라믹 피막을 형성하고 각 도전성 세라믹 피막에 의해 사출노즐의 전반부와 후반부를 별개로 온도 제어 하도록 한 것을 특징으로 하는 특허청구의 범위 제1항 기재의 사출성형기용 히터.
  5. 도전성 세라믹 피막을 절연성 세라믹 피막사이에 적층형성한 것을 특징으로 하는 특허청구의 범위 제1항으로 부터 제4항 기재의 어느 하나에 기재한 사출성기용 히터.
