Tsanangudzo yeplastic jekiseni molding nzira uye kugadzira nhanho nhanho

Mumakore makumi mashanu apfuura indasitiri yezvigadzirwa zvepurasitiki yakagadzira, yechikamu chikuru, ichitonga pamusoro pezvinhu zvakakosha, kunyange kupfuura indasitiri yesimbi. Plastics yakapinda mudzimba dzese zvisinei nemagariro, mumaguta ese anosanganisira ari kure zvakanyanya uye munyika dzakabudirira, sekune hupfumi hwese. Kuvandudzwa kweindastiri iyi kunonakidza uye kwakashandura nzira yenyika yatinogara mairi.

Jekiseni Molding Process

Mishonga yepurasitiki inosiyana zvakanyanya kubva kune imwe uye inokweretesa kune dzakasiyana nzira dzekugadzirisa. Chinyorwa chega chega chinokodzera zvirinani kune imwe yenzira, kunyangwe mazhinji achigona kugadzirwa neakawanda awo. Mumagadzirirwo mazhinji, iyo yekuumbwa iri muhupfu kana granular fomu, kunyangwe kune vamwe kune yekutanga preforming oparesheni isati yashandiswa. Kana kupisa kuchiiswa kune thermoplastic material kuti inyunguduke, inonzi ipurasitiki. Yatove yakanyungudutswa kana kupisa laminated zvinhu zvinogona kuyerera nekushandisa kumanikidza uye kuzadza mold apo iyo inoomesa uye inotora chimiro cheforoma. Iyi nzira inozivikanwa se injection kuumba. Iyo yakakosha musimboti wekuumbwa kwejekiseni inosanganisira anotevera matatu ekutanga mashandiro:

1. a) Simudza tembiricha yepurasitiki kusvika painoyerera pasi pekushandiswa kwekumanikidza. Izvi zvinowanzoitwa nekudziya uye kutsenga iyo yakasimba granules yezvinhu kuti igadzire kunyungudika neuniform viscosity uye tembiricha. Parizvino, izvi zvinoitwa mukati mebhodhoro remuchina uchishandisa screw, iyo inopa mechanical work (friction) iyo pamwe chete nekupisa kwebhodhoro kunyunguduka (plasticize) plastiki. Ndiko kuti, screw inotakura, inosanganisa uye inoisa plastiki zvinhu zvepurasitiki. Izvi zvinoratidzwa mumufananidzo
2. b) Bvumira kuomeswa kwezvinhu muforoma yakavharwa. Panguva ino zvinhu zvakanyungudutswa zvagara zvakanyungudutswa mumugodhi wemuchina zvinotamiswa (zvinoiswa jekiseni) kuburikidza nemhuno, iyo inobatanidza dhiramu kune dzakasiyana nzira dzeforoma kusvika yasvika kumakomba uko inotora chimiro chechigadzirwa chekupedzisira.
3. c) Kuvhurwa kwe mold yekubvisa chidimbu. Izvi zvinoitwa mushure mekuchengetedza zvinhu zviri pasi pekumanikidzwa mukati me mold uye kamwe chete kupisa (kwaishandiswa kupurasitiki) kunobviswa kuti zvibvumira kuti zvinhu zviome nenzira yaidiwa.

Mumagadzirirwo akasiyana-siyana ekuumba, mutsauko mukunyunguduka kana kupisa kwepurasitiki kunoita basa rakasiyana zvichienderana nekuti iri thermoplastic material kana thermofix.

Kusanganiswa kwe thermoplastic zvinhu zvinoitwa zvishoma nezvishoma mu plasticizing cylinder, pasi pemamiriro ezvinhu anodzorwa. Kupisa kwekunze kunopihwa neplasticizing cylinder kunowedzera kupisa kunoitwa nekukweshana kwespindle inotenderera nekusanganisa zvinhu. Kudzora tembiricha munzvimbo dzakasiyana dzeplasticizing cylinder inoitwa nenzira ye thermocouples inoiswa munzvimbo dzakasiyana munzira yechinhu, kubva kune hopper kusvika kumuromo. Thermocouples yakabatana kune otomatiki kudzora zviridzwa, izvo zvinochengetedza tembiricha yenzvimbo yega yega pane preset level. Nekudaro, tembiricha chaiyo yekunyunguduka ichaiswa mu mold inogona kunge yakasiyana neiyo yakanyorwa ne thermocouples pahumburumbira kana pamuromo.

Nechikonzero ichi, zvinokurudzirwa kuyera zvakananga tembiricha yechinhu nekugadzira chidimbu chidiki kubva mumuromo pane insulating plate uye kuita kuyerwa ipapo. Kusiyana kwekushisa mu mold kunogona kuburitsa zvikamu zvine hunhu hwakasiyana uye hukuru hwakasiyana, kupatsanurwa kwega kwega tembiricha yekushanda kunokonzeresa nekukurumidza kana kunonoka kutonhora kwehuwandu hwakanyungudutswa hwakabaiwa mugomba reforoma. Kana iyo mold tembiricha yakadzikiswa, chikamu chakaumbwa chinotonhora pasi nekukurumidza uye izvi zvinogona kugadzira yakatarwa yekutarisa muchimiro, yakakwira mukati mekushushikana, mechanical zvimiro uye kushata kwepamusoro kutaridzika.

Kuti uwane zvimwe nezve tsananguro ye epurasitiki jekiseni Kuumbwa nzira uye nzira yekugadzira nhanho nhanho, unogona kubhadhara kushanya kuDjmolding pa https://www.djmolding.com/ nokuti zvimwe info.
