Plastics kuumba nenzira dzakasiyana-siyana: jekiseni pamusoro pedzimwe nzira

Mukugadzira zvimedu zvepurasitiki zvinhu, marudzi akasiyana-siyana emhando anoshandiswa anoganhura mapurasitiki akawanda, achiomesa uye achichengeta chimiro chaunoda. Zviumbwa izvi zvakaiswa pamuchina unozovhura nekuvhara mold, iyo inozoisa kumanikidza kukuru kana zvichidikanwa, uye izvo zvinozofambisa kurodha mold nenzira dzekunze.

Iyo yepurasitiki zvinhu inobatwa mu mold pasi pekumanikidzwa apo ichiomesa zvakakwana kuitira kuti chimiro chayo chichengetedzwe mushure mekubviswa.

Steam, mvura inopisa, mafuta kana magetsi zvinoshandiswa kupisa mold. Rudzi rwekupisa runofanira kushandiswa mubasa rakapiwa rinosarudzwa nenzira inowanikwa uye nemhando yebasa racho pacharo.

Mune zvimwe zviitiko, molds inofanira kunyoroveswa nekutenderera kwemvura kana imwe inotonhorera, kuchengetedza kutonhora kwezviumbwa nguva dzose, zvishandiso zviripo nekuda kwechinangwa ichi.

Zvigadzirwa zvepurasitiki zvinosiyana zvakanyanya kubva kune mumwe uye zvinokweretesa kune dzakasiyana siyana nzira dzekuumba. Chinhu chega chega chiri nani kuchinjirwa kune imwe yenzira, kunyangwe mazhinji anogona kugadzirwa neakawanda adzo. Izvo zvinhu zvichaumbwa zviri mugranular powder fomu, kunyange kune vamwe kune yekutanga preforming oparesheni isati yashandiswa.

Jekiseni senzira yakanakisisa

Injecting molding ndiyo inonyanya kushandiswa nzira yekugadzira thermoplastic components. Mukuita uku, purasitiki yakanyungudutswa inomanikidzwa kupinda mugomba resimbi inofa iyo yakagadziridzwa kune inodiwa chigadzirwa chimiro.

Kana purasitiki yasimba zvakakwana, kufa kunovhurwa uye chikamu chinobviswa. Iyo mbishi yepurasitiki zvinhu inoiswa muchimiro chepellets mune hopper yemuchina. Inobva yapinda muheater kwainonyungudika. Plastiki yakanyungudutswa inozosaidzirwa mugomba rekufa nekuiswa kwakananga kwehydraulic kana mechanical pressure.

Kukwirira kukuru injection kuumba michina inogona kushandisa mazana akawanda ematani ekumanikidza uye inogona kushandiswa kugadzira zvidimbu zvakakura zvepurasitiki muchidimbu chimwe. Mienzaniso inosanganisira zvikamu zvemuviri zvemotokari zvakaita semagungano, mahodhi, mafenda, mabumper, uye magrill.

Iyo jekiseni maitiro anogona kupfupikiswa mumatanho mashanu:

Danho 1: Zvikamu zve mold zvakavharwa.

Danho rechipiri: Iyo piston inoenda kumberi uye inosundira zvinhu mukati mehumburumbira yekudziya, panguva imwechete ichipinza zvinhu zvepurasitiki muforoma.

Nhanho 3: Iyo piston inoramba iri munzvimbo iyi kwenguva yakati ichichengetedza kudzvanywa kuburikidza nenozzle. Munguva ino zvinhu zviri kutonhora uye kusimba sezvinodiwa kuchengetedza chimiro chemuumbi.

Nhanho 4: Iyo piston inodzokera, asi mold inoramba yakavharwa, huwandu hutsva hwezvinhu hunodonha kubva kune feeder hopper.

Danho rechishanu: Iyo mold inovhura panguva imwechete iyo inoramba zvikamu zvakaumbwa kuburikidza nekuita kwezvibodzwa.

Zvakanakira nzira iyi ndezvi:

• Kuchengetedza zvinhu, nzvimbo yekugadzira uye nguva yekugadzira.
• Kururama kwechimiro uye zviyero zvezvikamu zvakaiswa jekiseni.
• Mikana yekugadzira maburi uye kuisa zvinhu kubva kune zvimwe zvinhu izvo kugadzirwa kunopera.
• Smooth uye yakachena nzvimbo yezvikamu zvakabaiwa.
• Good resistance properties.
• Kukurumidza kugadzirwa kwehuwandu hwakawanda hwezvikamu.

Zvakaipa zvemuitiro ndezvi:

• Hazvikurudzirwe kugadzirwa kwakaderera nekuda kwekudhura kwekushandisa.
• Resins inogona kusimba isati yazadza mold kana ichibata nezvikamu zvakatetepa kwazvo.
• Zvikamu zvakaoma zvinowedzera mutengo wekushandisa.

Kuti uwane zvakawanda nezve mapurasitiki jekiseni kuumba nenzira dzakasiyana siyana: Jekiseni pamusoro pedzimwe nzira, unogona kushanya kuDjmolding pa https://www.djmolding.com/ nokuti zvimwe info.
