Pultrusion polding process ndi mtundu wa njira zodzipangira zokha zomwe zida zolimbikitsira monga ulusi wagalasi ulusi ndikumva pa chimango cha ulusi zimanyowetsedwa ndi guluu kudzera pakukokera kosalekeza kwa chipangizo chokoka, ndikukhazikika mu nkhungu pambuyo potenthetsa nkhungu ndi gawo lokhazikika. mawonekedwe, ndi kupanga nkhungu mosalekeza kumakwaniritsidwa.Kuchiritsa kwamtunduwu nthawi zambiri kumatchedwa kuchiritsa kutentha kwambiri.
Zipangizo zolimbitsa (ulusi wa galasi, magalasi opitilira magalasi ndi magalasi opangira magalasi, ndi zina zotero) pansi pa kukoka kwa zida za pultrusion, mutatha kuviika thanki ya guluu mokwanira zilowerereni njira ya guluu, imakhala ndi maulendo angapo oyenerera, preforming. Chinsinsi kupeza mawonekedwe oyambirira, potsiriza mu mkangano zitsulo nkhungu, nkhungu pansi zochita za mkulu kutentha kuchiritsa anachita, Motero akhoza kutulutsa pamwamba yosalala, khola kukula, mkulu mphamvu FRP mbiri.
pultrusion ndondomeko zida makamaka pultrusion makina, pultrusion makina dongosolo ndi zosavuta, zosavuta ntchito, palibe zofunika zapadera kupanga msonkhano dongosolo kupanga.Chifukwa chake, amagwiritsidwa ntchito kwambiri m'makampani a pultrusion.Iwo makamaka amapangidwa ndi ulusi kudyetsa chipangizo, impregnation chipangizo, kupanga nkhungu ndi kuchiritsa chipangizo, traction chipangizo, kudula chipangizo ndi mbali zina zisanu, lolingana njira zamakono ndi thonje mzere, impregnation, nkhungu ndi kuchiritsa, kukokera, kudula.
Pazinthu za FRP zokhala ndi gawo lokhazikika, ukadaulo wa pultrusion uli ndi zabwino zake.
Choyamba, chifukwa pultrusion ndi njira yodzipangira yokha yopangira, njira ya pultrusion imakhala yogwira ntchito kwambiri poyerekeza ndi njira zina zopangira FRP.
Kachiwiri, kuchuluka kwa zinthu zopangira ma pultrusion ndikokwera kwambiri, nthawi zambiri kuposa 95%.
Kuphatikiza apo, zinthu za pultrusion zimakhala ndi mtengo wotsika, magwiridwe antchito abwino kwambiri, mawonekedwe okhazikika komanso mawonekedwe okongola.Chifukwa cha ubwino wa ndondomeko pultrusion, mankhwala ake akhoza m'malo zitsulo, pulasitiki, matabwa ndi zipangizo zina, chimagwiritsidwa ntchito makampani mankhwala, ulimi ndi kuweta nyama, mafuta, zomangamanga, mphamvu ya magetsi, mayendedwe, zomangamanga tauni ndi madera ena.
