Kupfuura kuvepo kwayo kwese munharaunda yemazuva ano, vazhinji havatarise hunyanzvi hunofadza huri pasi pezvigadzirwa zvepurasitiki zvakatipoteredza. Zvakadaro nyika inonakidza iripo kuseri kwezvikamu zvepurasitiki zvakagadzirwa zvakawanda isu tisingafungire tichisangana nazvo zuva rega rega.
Dzvanya munzvimbo inonakidza yekuumbwa kwejekiseni repurasitiki, inyanzvi yekugadzira inoumba purasitiki yegranular mune isingaperi dhizaini yezvikamu zvepurasitiki zvakakosha muhupenyu hwezuva nezuva.
Kunzwisisa Injection Molding
Jekiseni molding inoshandisa hunyanzvi muchina kugadzira zvakafanana zvikamu zvepurasitiki muhuwandu hwakawanda. Purasitiki yakanyungudutswa inobayiwa pasi pekumanikidzwa kukuru kupinda mugomba reforoma, umo inotonhodza nekuomesa muchikamu chekupedzisira isati yabudiswa.
Maitiro acho anoda muchina wekuumba jekiseni, mbishi epurasitiki zvinhu, uye maviri-zvikamu simbi mold chishandiso chakasarudzika-chakagadzirwa kugadzira yaunoda chikamu geometry. Iyo mold tool inoumba chimiro chechimedu, chinosanganisira hafu mbiri dzakabatanidzwa pamwechete - rutivi rwepakati uye rutivi rwegomba.
Kana mold ichivhara, nzvimbo yegomba pakati pemativi maviri inoumba chimiro chemukati chechikamu chichagadzirwa. Plastiki inobayiwa kuburikidza nesprue kuvhura munzvimbo yegomba, ichizadza kuti iite chidimbu chepurasitiki chakasimba.
Kugadzirira Plastiki
Iyo jekiseni yekuumba maitiro inotanga nepurasitiki mune yayo mbishi, granular fomu. Iyo yepurasitiki zvinhu, kazhinji mupellet kana fomu yehupfu, giravhiti inodyiswa kubva kune hopper kupinda mukamuri yejekiseni yemuchina wekuumba.
Mukati mekamuri, plastiki inova pasi pekupisa kwakanyanya uye kumanikidzwa. Iyo inonyunguduka kuita yemvura saka inogona kubaiwa kuburikidza nejekiseni nozzle muchombo.
Kumanikidza Plastiki Yakanyungudutswa
Kana yanyungudutswa kuita fomu yakanyungudutswa, purasitiki inopinzwa nesimba mumudziyo weforoma ichidzvanyirirwa zvakanyanya, kazhinji 20,000 psi kana kupfuura. Ane simba hydraulic uye mechanical actuators inogadzira simba rakakwana kusundira viscous yakanyunguduka plastiki muforoma.
Iyo mold inochengetwa zvakare ichitonhorera panguva yejekiseni kuti ifambise kusimba kwepurasitiki, iyo inowanzopinda mukati me500 ° F. Iyo juxtaposition yeyakanyanya kudzvanywa jekiseni uye inotonhorera chishandiso inogonesa kukurumidza kuzadza kweakaomesesa mold zvinhu uye nekukurumidza kusimba kwepurasitiki kuita chimiro chayo chisingaperi.
Clamping uye Ejecting
A clamping unit inoshandisa simba kurwisa mahafu maviri e mold kuti arambe akavharika pakudzvanywa kwejekiseni. Kana plastiki yatonhora uye yaoma zvakakwana, kazhinji mukati memasekondi, mold inovhura uye chikamu chepurasitiki chakasimba chinobudiswa kunze.
Yakasunungurwa kubva mukuumbwa, chidimbu chepurasitiki ikozvino chinoratidza tsika yayo yakaumbwa geometry uye inogona kuenderera kune yechipiri kupedzisa matanho kana zvichidikanwa. Zvichakadaro, mold inovhara zvakare uye iyo cyclical jekiseni yekuumba inodzokorora ichienderera, ichigadzira zvikamu zvepurasitiki mumavhoriyamu kubva kune gumi nemaviri kusvika kumamirioni.
Kusiyana uye Kufunga
Mamiriyoni edhizaini akasiyana uye sarudzo dzezvinhu dziripo mukati mejekiseni rekuumba kugona. Insert inogona kuiswa mukati memudziyo wemidziyo inogonesa zvikamu zvezvinhu zvakawanda mupfuti imwe chete. Maitiro acho anogona kugarisa akasiyana einjiniya mapurasitiki kubva kuacrylic kusvika kunayiloni, ABS kusvika PEEK.
Nekudaro, iyo hupfumi hwekuumba jekiseni inofarira mavhoriyamu akakwira. Mold dzesimbi dzakagadzirwa dzinowanzodhura mari inopfuura $10,000 uye inoda mavhiki kuti igadzire. Iyo nzira inokwirisa apo mamirioni ezvikamu zvakafanana anopembedza mari yekutanga mukugadzirisa zvishandiso.
Zvisinei nehunhu hwayo husina kucheneswa, kuumbwa kwejekiseni kunoramba kuri chishamiso chekugadzira, kuwedzera kupisa, kudzvanywa uye simbi chaiyo kuti ibudise zviuru zvezvinhu zvakakosha kuhupenyu hwazvino. Nguva inotevera paunobata chigadzirwa chepurasitiki usipo, funga nezvekugadzira tekinoroji maitiro kumashure kwekuvapo kwayo.
