Gondohwe reextrusion rakakamurwa kuita marudzi maviri: gomo uye yakasimba.Hollow extrusion makondohwe anoshandiswa muchubhu uye tsvimbo extrusion michina.
Iyo extrusion gondohwe rinowanzo cylindrical yakazara chimiro, iyo inogona kukamurwa kuita magumo, shaft uye midzi.
Pamatani mahombe eextruder, makondohwe eextrusion anogadzirwa nechikamu chinochinja kuti awedzere kusimba kwekukotama kwelongitudinal.Panguva ino, extrusion cylinder inofanira kuva negomba remukati rine shanduko yakasiyana-siyana.
Iyo dhayamita yekunze yegondohwe reextrusion inotarwa zvichienderana nehupamhi hwemukati weiyo extrusion cylinder.
Iyo dhayamita yekunze yegondohwe reextrusion yeyakachinjika extruder inowanzokura kupfuura yegondohwe rekuextrusion.Iyo dhayamita yemukati yehumburumbira idiki 4-10mm.
Kureba kwegondohwe reextrusion rakaenzana nehurefu hwemutsigiri wegondohwe rekuwedzera pamwe nekureba kwehumburumbira yekuwedzeredza pamwe ne5 kusvika 10mm, kuitira kusundira kudzvinyirira zvakanyanya (ona extrusion residual material) uye extrusion gasket kunze kwehumburumbira.Izvo zvinhu zvegondohwe reextrusion ndeye chrome-nickel-molybdenum uye chrome-nickel-tungsten alloy.Iyo yakaunganidzwa extruded tsvimbo muviri inogadzirwa nechromium-nickel-tungsten-vanadium alloy, uye mudzi unogadzirwa nechromium-nickel-molybdenum alloy.
Iyo extrusion gondohwe rinoiswa pasi pekunetseka kukuru kwekukotama uye kudzvinyirira kushushikana panguva yekushanda.Naizvozvo, kugadzikana uye
kusimba kwegondohwe re extrusion kunofanirwa kuongororwa panguva yeextrusion.
