Kuti ugadzire molds dzakatetepa-yakakomberedzwa zvakanaka, iyo fluidity yeatete-walled jekiseni zvinhu zvinofanirwa kuve zvakanaka, uye zvinofanirwa kuve nehombe yekuyerera-kusvika-kureba reshiyo.Iyo zvakare ine yakanyanya kusimba simba, yakanyanya kupisa kupisa tembiricha, uye yakanaka dimensional kugadzikana.Pamusoro pezvo, kupikisa kupisa, kunonoka kwemurazvo, kuungana kwemuchina uye kutaridzika kwemhando yezvinhu kunofanirwawo kuongororwa.Ngatitarisei iyo theoretical hwaro hwehutete-walled mold kugadzira.
Parizvino, zvinhu zvinoshandiswa zvakanyanya mukuumba jekiseni zvinosanganisira polypropylene PP, polyethylene PE, polycarbonate (PC), acrylonitrile-butadiene-styrene (ABS) uye PC/ABS misanganiswa.Iyo yekuzadza maitiro uye kutonhora maitiro eyakajairwa jekiseni molding mu mold inopindirana.Kana iyo polymer yakanyungudika ichiyerera, kumberi kwakanyunguduka kunosangana nepakati pepamusoro kana mudhuri wemadziro ane tembiricha yakadzikira, uye dhiri rinoumbwa pamusoro pepamusoro. iyo condensation layer ine simba rakakura pakuyerera kwepolymer.
Imwe ongororo yakadzama uye yakazara inodiwa pahunhu hweiyo condensation layer muutete-madziro jekiseni molding.Naizvozvo, basa rakawanda rinoda kuitwa pakuenzanisa kwenhamba kwemutete-walled jekiseni molding.Pfungwa yekutanga ndeyekuita ongororo yakadzama uye yakazara yedzidziso yehutete-madziro jekiseni molding, kunyanya zvimiro zveiyo condensation layer, kuitira kupa mazano ane musoro ekufungidzira uye mamiriro emuganhu.Kubva pane ongororo iri pamusoro, zvinogona kuonekwa kuti mukugadzira jekiseni rakatetepa-madziro, mamiriro mazhinji akasiyana zvakanyanya kubva kune akajairwa jekiseni molding.
Paunenge uchifananidzira, fungidziro dzakawanda uye mamiriro emuganho weiyo melt flow mathematical modhi inoda kunyatsogadziriswa mutete-wall jekiseni molding.
