Ekubunjweni kokucindezela, ama-halves amabili esikhunta afanayo afakwa emshinini wokunyathelisa (imvamisa i-hydraulic), futhi ukunyakaza kwawo kunqunyelwe ku-axis perpendicular endizeni yesikhunta.Ingxube ye-resin, i-filler, i-reinforcing material, i-ejenti yokuphulukisa, njll iyacindezelwa futhi yelashwe esimweni sokuthi igcwalisa yonke indawo yokufa kokubumba.Le nqubo ivamise ukuhlotshaniswa nezinto eziningi, okuhlanganisa:
I-Epoxy resin prepreg fiber eqhubekayo
Inhlanganisela yokubumba amashidi (SMC)
Izinto zemodeli yokulahla (DMC)
I-Bulk Molding Compound (BMC)
I-Glass mat thermoplastic (GMT)
Izinyathelo zokubumba ukucindezela
1. Ukulungiswa kwezinto zokubumba
Ngokuvamile, izinto zokubumba eziyimpuphu noma eziyimbudumbudu zifakwa emgodini, kodwa uma umthamo wokukhiqiza mkhulu, ukwelashwa kusengaphambili kuvame ukuba nenzuzo.
2. Ukushisa kwezinto zokubumba
Ngokushisa izinto zokubumba kusengaphambili, umkhiqizo obunjiwe ungelashwa ngokufanayo, futhi umjikelezo wokubumba ungafinyezwa.Ngaphezu kwalokho, njengoba ingcindezi yokubumba ingancishiswa, nayo inomphumela wokuvimbela umonakalo wokufaka kanye nesikhunta.Izishisi zokushisa komoya oshisayo nazo zisetshenziselwa ukushisa ngaphambili, kodwa ama-preheaters aphezulu asetshenziswa kakhulu.
3. Ukusebenza kokubumba
Ngemuva kokuthi izinto ezibunjwayo zifakwe ekubunjweni, impahla iqala ukuthambisa futhi igeleze ngokugcwele ngaphansi kwengcindezi ephansi.Ngemuva kokuphelelwa amandla, isikhunta siyavalwa futhi sicindezelwe futhi ukuze selaphe isikhathi esinqunyiwe.
I-polyester engasetshenzisiwe kanye ne-epoxy resins engakhiqizi igesi ayidingi kukhishwa.
Lapho ukukhishwa kwegesi kuyadingeka, isikhathi sokuhlela kufanele silawulwe.Uma isikhathi singaphambili, inani legesi elikhishwe lincane, futhi inani elikhulu legesi lizovalwa emkhiqizweni, elingase likhiqize ama-bubbles endaweni yokubumba.Uma isikhathi sesiphuzile, igesi ibanjelwe emkhiqizo olaphelwe kancane, kunzima ukuphunyuka, futhi ingabangela imifantu kumkhiqizo obunjiwe.
Emikhiqizweni enezindonga eziwugqinsi, isikhathi sokuphulukisa sizoba side kakhulu, kodwa uma ukuphulukiswa kungaqediwe, amabhamuza angase akhiqizwe endaweni ebumbayo, futhi imikhiqizo enesici ingase ikhiqizwe ngenxa yokuguga noma ukushwabana kwangemuva.
