Chikamu chepurasitiki chega chega chinoda imwe nzira yekugadzira iyo inogona kunge yakasiyana zvakanyanya kubva kune chimwe chigadzirwa kuenda kune chimwe.Jekiseni molding inoshandiswa kugadzira zvinhu zvakasimba ukuwo blowing molding inoshandiswa kugadzira zvigadzirwa zvepurasitiki zvine nzvimbo dzisina mhango, senge mabhodhoro nemidziyo.
Injection stretch blow molding inobatanidza kuumbwa kwejekiseni uye kuvhuvhuta maitiro.Plasitiki inotanga kuumbwa kuita yakasimba preform, kugadzira mutsipa webhodhoro wakaiswa threaded.Kamwe iyo preform yatonhora inodyiswa mumushini wakatambanudzwa wekuputira mold.Iyo preform inozodziiswa zvakare uchishandisa infrared heater uye inofuridzirwa mubhodhoro repurasitiki nemhepo yakamanikidzwa yakamanikidzwa.
Iyo Injection Molding process
Jekiseni molding inoshandiswa kugadzira yakakwira vhoriyamu huwandu hwezvigadzirwa zvepurasitiki kubva muhukuru kubva kuzvinhu zvakakura kusvika kuzvinhu zvidiki zvinoda micro-chaizvo.
Kune akawanda marudzi enzira dzekugadzira dzakaiswa pasi pejekiseni rekugadzira, senge thermoplastic jekiseni kuumba, pamusoro pekuumbwa, kuisa kuumbwa, inotonhora mumhanyi kuumbwa uye inopisa mumhanyi kuumbwa.
Thermoplastic Injection Molding
Thermoplastic jekiseni molding inoshandisa thermoplastic polymer, zvichireva kuti inoshanduka kuita yemvura kana yapiswa.Kusiyana nemapurasitiki ethermoset anotonhorera kuita yakasimba zvachose, thermoplastics inogona kubviswa mumvura mushure mekutonhodza kuita yakasimba.
Overmolding
Overmolding, kana kuumbwa kwepfuti mbiri, inzira inovhara jekiseni mold pamusoro pechimwe chinhu, sesimbi, kunatsiridza mashandiro kana kusimba kwechigadzirwa.Mushonga wakafanana nerabha, unonzi thermoplastic elastomer (TPE), chinhu chinowanzo shandiswa overmold zvinhu.Muenzaniso weTPE overmold application ndeye mubato unobata pane bhurasho remazino.Overmolds inogona zvakare kushandiswa kusimbisa zvigadzirwa nezvikamu zvakagadzirwa kubva kune akati wandei majekiseni mold.
Isa Molding
Senge overmolding, isa molding ijekiseni moldingprocess inosanganisa maviri kana anopfuura zvikamu kuita chimwe chete chakapera chigadzirwa.Isai jekiseni molding inopinza chikamu mugomba rejekiseni mold uye zvinhu zvepurasitiki zvinozadzwa zvakatenderedza pekuisa.Insets inogona kuwedzera simba kune chigadzirwa uye kubvisa kudiwa kwezvimwe zvikamu kuderedza uremu hwechigadzirwa.
Cold Runner Injection Molding
Cold runners molds anoshandisa sprue kuzadza vanomhanya vanopinza resin yepurasitiki mugomba.Mune 2 plate molds, mumhanyi system uye zvikamu zvakasungirirwa, uye ejection system inogona kushandiswa kuparadzanisa vaviri kubva kune mold.Iyo inotonhora inomhanya inogona kuderedza tsvina kuburikidza nekudzokorora uye kudzorera zvinhu, asi izvi zvinogonawo kuwedzera nguva yose yekutenderera. .Cold runner masisitimu anogona kushandiswa kune akasiyana mapolymers uye anogona kubvumira shanduko yemavara nyore.
Hot Runner Molds
Hot runners molds dzinoshandisa manifold kupisa purasitiki yakanyunguduka resin uye yozotumira izvo zvinhu nepagedhi kuzadza mhango.Iyo miviri mikuru yemhando yekupisa inomhanya molds inodziya kunze uye inopisa mukati.Iyo yekunze inodziya molds inogona kushandiswa nepolymer iyo isinganyanyi kutaridzika kudziya kwekuchinja ukuwo mukati inopisa inopisa mumhanyi molds inobvumira kudzora kurinani kwekuyerera kwezvinhu.
Nekuti kupisa mumhanyi kuumbwa hakudi kushandiswa kwevamhanyi, zvingangorasa zvinhu zvinodzikiswa uye kudzokorodza uye kugayazve uye maitiro epurasitiki mhandara haakonzerese nguva yekutenderera kutenderera.
The Blow Molding Process
Munguva yekuumba kuvhuvhuta, purasitiki yakasvibirira inoumbwa kuita chubhu isina mhango ine magumo akavhurika anonzi parison.Iyo jeri inotsikirirwa musimbi yakatonhorera mold uye mweya wakamanikidzwa unomanikidzwa kupinda mujere.Kana purasitiki yakaumbwa ichitonhora nekuoma, mold yesimbi inovhura uye inodzinga chigadzirwa.
