北京塑料挤出厂谈挤管机头的特点
添加时间:2017-07-15

  要说到挤出管材成型需要用的设备,那么挤管机头就是不得不说的一个东西了,挤管机头分为直通式、直角式、偏置式三种。下面北京塑料挤出厂就来和大家说说这三种挤管机头的特点。

  直通式:1.结构简单、制造容易、成本低、料流阻力小;

  2.适用于生产中、小口径塑料管材;

  3.采用外径定径、芯模加热困难及定型段长;

  4.由分流器支架产生的熔合纹较难消除。

  直角式:1.大小口径的塑料管材均可适用;

  2.机头结构较为复杂;

  3.无分流器支架、无熔接痕;

  4.定型段长度可以较短。

  偏置式:1.大小口径塑料管材均可适用;

  2.机头结构较复杂;

  3.没有分流器支架、熔接痕;

  4.芯轴易加热、定型段较短。
