2. auala gaosi (ma se faiga palasitika) e aofia ai: faʻapipiʻiina o le mamafa (molding), extrusion (extrusion molding), tui faʻapipiʻiina (injection molding), faʻafefeteina (hollow molding), calendering, etc.

⑴ faʻapipiʻi faʻamalosi: faʻapipiʻi poʻo le faʻapipiʻiina o le faʻaogaina. E masani ona faʻaaogaina mo le faʻaogaina o palasitika thermosetting e pei o le phenolic resin, urea-formaldehyde resin ma le unsaturated polyester resin.

⑵ extrusion: extrusion molding, o le faaaogaina o le extrusion masini (extruder) o le a vevela resin faaauau pea e ala i le limu, extrusion manaomia foliga o le oloa method.Extrusion o nisi taimi e faaaoga i le thermosetting palasitika molding, ma e mafai ona faaaoga i le mamanu o foam plastics.The lelei o le extrusion e mafai ona extrude ituaiga eseese o oloa, maualuga gaosiga lelei, otometi ma faaauau pea;O le e le lelei o le thermosetting maea palasitika e le mafai ona faʻaaogaina lautele i lenei auala o le gaosiga, o le tele o oloa e faigofie ona maua ai se eseesega. .

⑶ Faʻameamea faʻapipiʻi: faʻapipiʻi tui. O le faʻaogaina o le tui o le faʻaogaina o le masini tui (poʻo le masini tui) e faʻafefeteina ai le maea vevela i lalo o le maualuga o le mamafa i totonu o le paʻu pe a maeʻa le malulu, faʻamalosia e maua ai le auala oloa. ma le foam palasitika maea molding.Injection molding ei ai le lelei o le saoasaoa o le gaosiga o le saoasaoa, maualuga le lelei, faʻaogaina otometi, ma e mafai ona faʻapipiʻiina vaega lavelave, aemaise lava le talafeagai mo le tele o gaosiga. O le faʻaletonu o le tau o meafaigaluega ma faʻafefe e maualuga, ma le tui. e faigata ona fa'amamāina le masini fa'apipi'i.

⑷ fa'ali'i: fa'a'o'oo'u fa'a'u'u po'o fa'a'o'o'u molding.Blow molding o se metotia o le feula o'o'o oloa e ala i le mamafa o le ea fa'apipi'i e tapuni ai le pulu pulu vevela vevela i totonu o le limu.O le faʻafefeteina e aofia ai auala e lua o le faʻafefeina o ata tifaga ma le faʻafefeina o oloa gaʻo. Faatasi ai ma le faʻafefeina o le auala e mafai ona maua ai ata tifaga, o fagu eseese, paelo, POTS ma meataalo a tamaiti.

⑸ Calendering: O se auala faʻapipiʻi lea e faʻaogaina ai resini ma mea faʻaopoopo eseese (kolo, faʻamamaina, ma isi) i ata tifaga poʻo laupepa e ala i va i le va o le lua pe sili atu faʻafeagai faʻataʻavalevale o le kalena, ona paʻu ese ai lea o le uila o le kalena. le kalena, ona faʻapipiʻiina lea e le cooling.Calendering e masani ona faʻaaogaina i le polyvinyl chloride resin molding method, e mafai ona gaosia ata tifaga, laupepa, ipu, paʻu faʻapitoa, fola fola ma isi oloa.

Yantai Dongyuan Plastic Products Co., Ltd.PE upega maea palasitika, North Korean hemp (PP) mea upega, fetilaisa kemikolo si'i upega, upega sisi'i oloa, upega fa'amaufa'ailoga ta'avale, upega saogalemu, maea fa'atupuina, upega saogalemu itu va'a ma fa'amatalaga fa'apitoa eseese. o le lalaga lima lalaga upega, upega saogalemu, e masani ona faʻaaogaina i totonu o le taulaga, vailaʻau vailaʻau gaosiga o pisinisi, saito ma suauʻu gaosiga pisinisi o le teuina o meaai soya ma le felauaiga. Polyethylene (PE) ma Korean hemp (PP) maea e masani ona faʻaaogaina i alamanuia, faʻatoaga. ma faigafaiva.
