BMC (DMC) zvinhu ndiko kupfupikiswa kwehuwandu (hukanyi) hwekuumba makomisheni, kureva, mizhinji yekuumba makomboni.Inowanzo kunzi unsaturated polyester boka rekuumba musanganiswa muChina.Zvishandiso zvaro zvikuru zvakakura ma prepregs akagadzirwa neGF (yakachekwa girazi faibha), kumusoro (unsaturated resin), MD (filler calcium carbonate) uye zvakasiyana-siyana zvinowedzera.Zvishandiso zveBMC zvakatanga kushandiswa mune yaimbova West Germany neBritain muma1960, ndokuzogadzirwa zvakanyanya muUnited States neJapan muma1970 nema1980 zvichiteerana.NokutiBMC yakawanda yekuumba makomishenivane zvinhu zvemagetsi zvakanakisa, midziyo yemagetsi, kudzivirira kupisa, makemikari ekudzivirira, uye kuchinjika kune akasiyana maitiro ekuumba, vanogona kusangana nezvinodiwa zvekushanda kwezvigadzirwa zvakasiyana, saka ivo vanonyanya kufarirwa nevashandisi.
(1) Hunhu uye kushandiswa kweBMC
BMC ine yakanaka yemuviri, yemagetsi uye yemagetsi zvivakwa, saka inoshandiswa zvakanyanya, senge kugadzira mekiniki zvikamu sezvikamu zvegiya bhokisi, pombi dzekudya, mavharuvhu anovhara, mabumper uye zvichingodaro;Inoshandiswawo zvakanyanya mukufamba nendege, zvivakwa, fenicha,zvigadzirwa zvehutsanananezvimwe zvinoda kuramba kwekudengenyeka kwenyika, kunonoka kwemurazvo, runako nekusimba;Mumunda wayo wemagetsi echinyakare, kushandiswa kwayo kunowedzera uye kwakawedzera.
(2) Zvigadzirwa zvemhando
Magetsi zvikamu (insulator, chinja 29, mita bhokisi,circuit breaker shell, terminal block, akasiyana epamba kana ekutengesa emagetsi chigadzirwa mabhomba), zvikamu zvemotokari (headlight reflector, rear door, speaker shell, etc.), mita shell, gudza remidziyo yekurira.
(3) BMC kugadzira nzira
BMC jekiseni rekugadzira muchina inonyanya kuita yeBMC yakawanda zvinhu, iyo inomanikidzwa kupinda muBMC dhiramu kuburikidza neBMC feeder, yobva yaendeswa kumberi kwedhiramu kuburikidza nesiruu, yobva yaiswa mugomba rekurapa nekuumbwa.
BMC ndeye thermosetting zvinhu.Kupisa kwebhodhoro remushini wekuumba jekiseni haifaniri kunge yakanyanyisa.Iyo inowanzoiswa pamadhigirii makumi matanhatu kuti ifambise kuyerera kwezvinhu.
BMC jekiseni rekuumba muchina inonyanya inyanzvi yekugadzira thermosetting lumpy zvinhu.Iko kune seti ye hydraulic system muchikamu chekudyisa, iyo inomanikidza lumpy zvinhu mudhiramu kana screw inotarisirwa.BMC jekiseni rekugadzira muchina wakakodzera mold ine yakaoma chimiro, iyo inogadziriswa nejekiseni kuumba, ine yakakwirira chigadzirwa kunyatsoshanda uye kuderera kwekushanda nesimba.
BMC kuumba nzira dzinosanganisira kumanikidza kuumba, kutamisa kuumba uye jekiseni kuumba.Munguva pfupi yapfuura, jekiseni kuumba ndiyo nzira huru.
① Kumanikidza kuumba nzira, ona SMC yekuumba nzira.
② Kutamisa nzira yekuumba.Iyo midziyo ine poto mhando uye yekubatsira piston mhando, kunyanya yekubatsira piston mhando.
