5 Mhando dzePlastiki Molding Kune Yetsika Plastic Zvigadzirwa Vagadziri

Kune marudzi maviri epurasitiki: thermoplastic uye thermo-yakaoma. Thermoplastics inonyungudika uye thermoplastic haina. Musiyano uri pakuti mapolymer anoumbwa sei. Polymers, kana maketani emaatomu, akafanana ne-dimensional tambo mu thermoplastics, uye kana ikanyunguduka, inogona kutora chimiro chitsva. Mu thermo-rigid iwo matatu-dimensional network anogara achichengeta chimiro chavo. Maitiro akasiyana-siyana anoshandiswa kugadzira kana kuumba mapurasitiki, mamwe anongoshandira thermoplastics, mamwe chete kune thermo-rigid uye mamwe maitiro anoshanda ese ari maviri.

Extrusion

Extrusion inzira yekuumba iyo inotanga ne "mbishi" zvinhu zvepurasitiki senge granules, poda, kana maparera. Hopper inodyisa plastiki mukamuri inotenderera. Kamuri, inonzi extruder, inosanganisa uye inonyungudutsa plastiki. Ipurasitiki yakanyungudutswa inomanikidzwa kunze kuburikidza nefa uye inotora chimiro chechigadzirwa chakapedzwa. Chinhu chacho chinowira pabhandi rekutakura umo chinotonhodzwa nemvura uye chinochekwa. Zvimwe zvigadzirwa zvinogona kugadzirwa neextrusion zvinosanganisira mapepa, firimu uye machubhu.

Injecting molding

Injecting molding inoshandisa nheyo imwechete se extrusion. Plastiki yakasvibirira inodyiswa kubva muhopi kupinda mukamuri yekudziya. Nekudaro, pachinzvimbo chekumanikidzwa kupfuura nemufa, inomanikidzwa kupinda muforoma inotonhora pasi pekumanikidzwa kukuru. Ipurasitiki inotonhora uye inoomesa, uye chigadzirwa chinocheneswa uye chinopedzwa. Zvimwe zvinogadzirwa nejekiseni zvinosanganisira kurongedza bhotela, kepisi dzemabhodhoro, matoyi uye fenicha yemugadheni.

Bika kuumbwa

Kuvhuvhuta kunoshandisa jekiseni remhepo mushure mekunge purasitiki yaburitswa kana kubaiwa. Extrusion blow molding inoshandisa dhidhi inogadzira inopisa yepurasitiki chubhu ine yakatonhodzwa mold yakaitenderedza. Mhepo yakadzvanywa inoiswa jekiseni kuburikidza nechubhu kumanikidza plastiki kuti itore chimiro che mold. Izvi zvinobvumira vagadziri kuti vagadzire anoenderera uye akafanana maumbirwo asina maburi, asi kuti aite jekiseni-kuumba imwe neimwe yadzo. Jekiseni-kuvhuvhuta kunoshandisawo jekiseni mold, asi panzvimbo yekuwana chigadzirwa chakapedzwa, mold inhanho yepakati umo plastiki inodziirwa kuti ifuridzirwa kune chimiro chayo chekupedzisira mune imwe yakasiyana inotonhora mold.

Compression Kuumbwa

Compression molding inzira yekutora yakafanotsanangurwa vhoriyamu yepurasitiki, woiisa muforoma, wozoshandisa imwe mold kuipwanya kana kuitsikirira muforoma yekutanga. Maitiro acho anogona kuve otomatiki kana manyorerwo uye akakodzera kune ese ari maviri thermoplastic uye thermo-rigid zvinhu.

Thermoformed

Thermoforming inzira yekupisa firimu repurasitiki pasina kuinyungudusa, ichinyorovesa zvakakwana kuti itore chimiro cheforoma iyo inodzvanywa. Mugadziri anoita kuti purasitiki itore chimiro chainoda uchishandisa yakakwira pressure, vacuum kana mold yechirume. Mushure mekunge chigadzirwa chakapedzwa chatonhora, chinobviswa kubva muforoma uye zvakasara zvinodzokororwa kuti zvishandiswe mufirimu idzva.

Plastic injection molding process

Injection molding ndiyo imwe yenzira huru dzekugadzira plastiki. Nhanho yekutanga mukuumbwa kwejekiseni ndeyekudyisa magirafu epurasitiki muhopi, ayo anobva adyisa magranules mucylinder. Dhiramu rinodziirwa uye rine imwe siruuru kana ramu jekiseni. Imwe sikuruu inowanzowanikwa pamichina inoburitsa zvikamu zvidiki. Iyo inodzosera screw inopwanya magranules, zvichiita kuti zvive nyore kuti plastiki inyungudike. Kumberi kwedhiramu, siruu inodzokorodza inotyaira purasitiki yakanyungudutswa mberi, ichibaya purasitiki kuburikidza nemuromo uye muforoma isina chinhu. Kusiyana nedhiramu, mold inochengetwa ichitonhora kuomesa purasitiki kuita chimiro chakakodzera. Iyo mold plates inobatwa yakavharwa nendiro huru (inonzi ndiro inofambiswa). Iyo ndiro inofambiswa yakabatanidzwa kune hydraulic piston, iyo inoshandisa kumanikidza pane mold. Iyo yakavharwa clamping yepurasitiki mold inodzivirira kuti irege kupukunyuka, izvo zvaizogadzira deformation muzvikamu zvakapedzwa.
