Apparatus for producing corrugated plastic pipes |
摘要 |
Half dies for pipe forming slide along a plate and are pressed together by a guide. Each half die comprises a metal core wit higher heat conductivity and lower specific gravity than steel enclosed by a supporting steel block whose rear side contacts the guides and whose underside surface slides on the plate. A forming cavity in the cores is linked to vacuum channels. |
