Pakapangidwe kameneka, magawo awiri ofananira a nkhungu amayikidwa mu makina osindikizira (kawirikawiri ma hydraulic), ndipo kuyenda kwawo kumangokhala pa axis perpendicular kwa ndege ya nkhungu.The osakaniza utomoni, filler, kulimbikitsa zinthu, kuchiritsa wothandizira, etc. mbamuikha ndi kuchiritsidwa mu boma kuti amadzaza patsekeke lonse akamaumba kufa.Izi nthawi zambiri zimagwirizanitsidwa ndi zinthu zambiri, kuphatikizapo:
Epoxy utomoni prepreg mosalekeza CHIKWANGWANI
Mapepala Omangira Mapepala (SMC)
Dumpling model material (DMC)
Bulk Molding Compound (BMC)
Glass mat thermoplastic (GMT)
Masitepe opangira compress
1. Kukonzekera zipangizo zomangira
Nthawi zambiri, zida zomangira za ufa kapena granular zimayikidwa pabowo, koma ngati kuchuluka kwake kuli kwakukulu, kuwongolera nthawi zambiri kumakhala kopindulitsa.
2. Kutentha kwa zinthu zoumba
Powotcha zinthu zomangira pasadakhale, chinthu chopangidwacho chikhoza kuchiritsidwa mofanana, ndipo kuzungulira kwake kumatha kufupikitsidwa.Kuonjezera apo, popeza kukakamiza kuumba kumatha kuchepetsedwa, kumakhalanso ndi zotsatira zoletsa kuwonongeka kwa kuika ndi nkhungu.Zowumitsira mpweya wotentha zimagwiritsidwanso ntchito potenthetsera, koma ma preheated ma frequency apamwamba amagwiritsidwa ntchito kwambiri.
3. Kuumba ntchito
Pambuyo poyikapo zinthuzo mu nkhungu, zinthuzo zimafewetsedwa ndikuyenda bwino pansi pa kupanikizika kochepa.Pambuyo potopa, nkhungu imatsekedwa ndikukanikizidwanso kuti ichire kwa nthawi yokonzedweratu.
Unsaturated polyester ndi epoxy resins omwe sapanga mpweya safuna utsi.
Pamene degassing ikufunika, nthawi yokonzekera iyenera kuyendetsedwa.Ngati nthawiyo ili kale, kuchuluka kwa gasi wotulutsidwa kumakhala kochepa, ndipo gasi wochuluka adzasindikizidwa mu mankhwala, omwe angapangitse thovu pamtunda wowuma.Ngati nthawi yachedwa, mpweya watsekeredwa mu mankhwala ochiritsidwa pang'ono, zimakhala zovuta kuthawa, ndipo zingayambitse ming'alu ya mankhwala opangidwa.
Pazinthu zokhala ndi mipanda yokhuthala, nthawi yochiritsa idzakhala yayitali kwambiri, koma ngati kuchiritsa sikunathe, ming'oma imatha kupangidwa pamtunda, ndipo zinthu zopanda pake zimatha kupangidwa chifukwa cha kupunduka kapena kutsika.
