The dunƙule da ganga masana'antu tsari yawanci ya hada da aikace-aikace review, abu da surface-tsarin zaɓi, blank shirye-shirye, m da gama machining, zafi magani ko hardfacing, daidaici kammala, girma dubawa da kuma kariya shiryawa. Odar ba ta duniya ba ce. Dole ne a tsara shi a kusa da lissafi, jiyya da ma'auni na ƙarshe na takamaiman sashi.

A layi daya tagwaye dunƙule extruder yana da biyu akai-akai diamita intermeshing skru da aka gina daga modular abubuwa. Yawancin suna jujjuyawa, suna gudana cikin babban sauri don haɗakarwa mai ƙarfi - wanda ke sanya su daidaitaccen injin haɗawa, masterbatch, WPC da pelletizing. Ba kamar na'ura mai ɗaukar hoto ba, ana iya sake gina bayanin martaba don kowane sabon tsari.

Ganga mai dunƙule guda ɗaya ita ce dunƙule guda ɗaya da ke jujjuya cikin ganga mai zafi mai zafi, isarwa, narkewa da kuma fitar da robobi ta hanyar mutu. An saita aikin da abubuwa uku: rabon L/D, rabon matsawa da nau'in dunƙule (misali, shinge ko haɗawa). Shi ne mafi tattali zabi ga high-fitarwa extrusion na uniform abu - film hurawa, bututu daga pellets, sheet da granulation.

Twin sukurole extruder yana amfani da sukurori guda biyu masu tsaka-tsaki a cikin ganga tagwaye don ciyarwa, narke, gaurayawa da jujjuya filastik ta mutuwa. Babban iyalai guda biyu sune conical (sukurori, mafi kyau don bututun PVC kai tsaye, bayanin martaba da extrusion na allo) da kuma layi daya (diamita mai tsayi, screws masu ɓarna, mafi kyau don haɗawa, granulation da haɗuwa mai girma).
