jekiseni molding yakanganisa musana ?

Mhedzisiro yekumanikidza kumashure jekiseni kuumbwa kunokosha zvikuru, uye inobata zvakananga kuzadza kwekunyunguduka uye kunaka kwezvikamu zvepurasitiki.

(1) Zvakakodzera back pressure inogona kuvandudza kunaka kwezvigadzirwa

①Inogona kubatanidza kunyungudika mudhiramu, kuwedzera density, uye kuvandudza huwandu hwejekiseni, chigadzirwa uremu uye dimensional kugadzikana;

②Iyo gasi mukunyunguduka inogona kuva “kudzvinyirirwa kunze” kuderedza maruva emhepo uye mabhuru emukati pamusoro pechigadzirwa, uye kuvandudza kufanana kwegloss;

③Deredzera kukurumidza kudzoka kwesiruu kuita kuti kunyunguduka mudhiramu kuzara plastiki., kuwedzera kufanana kwekusanganiswa kwe toner, masterbatch uye nyungudika, uye dzivisa kusanganiswa kwemavara muchigadzirwa;

④ Kunyatso wedzera kumanikidza kumashure kunogona kuvandudza kuderera kwechigadzirwa chepamusoro uye glue inomhanya ichitenderedza chigadzirwa.;

⑤Inogona kuwedzera humidity yekunyungudika, kunatsiridza plasticization kunaka kwekunyunguduka, uye kuvandudza fluidity yekunyunguduka paunenge uchizadza mold, uye pamusoro pechigadzirwa hachina mitsara inotonhora yeglue.

(2) Mhedzisiro yekudzvinyirirwa kumashure kwakanyanya pane zvigadzirwa

①Iyo yekunyunguduka kumucheto kumberi kwembiru yakakwira zvakanyanya, tembiricha yezvinhu yakakwira, uye viscosity inoderera. Kuyerera kwakadzokera kumashure kwekunyunguduka mune screw groove uye kuwedzera kwekuyerera kwekuyerera pakati pembiya uye screw kunoderedza kuita kwepurasitiki.;

②Kumapurasitiki asina kugadzikana kwemafuta (zvakadai sePVC, POM, Nekuti iyo IC tray ine huremu huremu) kana mavara, kutonhora kwezvinhu zvakanyungudutswa kunowedzera uye nguva yekupisa mubhodhoro inowedzera, zvichikonzera kuora kwekupisa, kana chiyero chekuchinja kwemavara chinowedzera, uye ruvara rwepamusoro uye kupenya kwechigadzirwa Kuwedzera kuipa;

③Kumanikidzwa kwemusana kwakanyanyisa, screw inodzokera zvishoma nezvishoma, uye pre-plastiki kudzoka nguva yakareba, izvo zvichawedzera kutenderera nguva uye kuderedza kugadzirwa kwekubudirira;

④Kumanikidzwa kwemashure kwakakwira uye kunyunguduka kwakakwira. Mushure mekunge glue yaiswa jekiseni, muromo unowanzonyunguduka kumedzerera. Apo glue rinoiswa nguva inotevera, iyo inotonhora zvinhu mumhanyi wenozzle inovhara muromo kana inotonhora zvinhu mavara anozoonekwa muchigadzirwa;

⑤Munguva ye jekiseni kuumba muchina kushanda nzira, iyo muromo inodonha nekuda kwekunyanya kudzvinyirira kumashure, iyo inorasa midziyo uye inoita kuti mhete yekudziya iri pedyo nemuromo upise;

⑥ Kupfeka kwemuchina we pre-plastiki meshini uye screw barrel inowedzerwa.

(3) Mhedzisiro yekushomeka kwemashure kune zvigadzirwa

① Kana kudzvinyirirwa kumashure kwakaderera, sikururu inodzokera nekukurumidza, density yekunyungudika inoyerera ichienda kumucheto kwemberi kwe fan barrel idiki (zvakasununguka), uye kune mhepo yakawanda;

②Inozotungamira kune yakashata plasticization mhando, isina kugadzikana jekiseni volume, uye shanduko huru mukurema kwechigadzirwa uye saizi yechigadzirwa;

③Pamusoro pechigadzirwa pachaita shrinkage, mhepo inotumbuka, mitsara yezvinhu zvinotonhora, kusaenzana kupenya uye zvimwe zvisingadiwe zviitiko;

④ Mabhuru ari nyore kuoneka mukati mechigadzirwa, uye periphery nemapfupa echigadzirwa zviri nyore kufamba uye kusagutsikana neglue.

(4) Nhungamiro nzira yekudzosera kumashure kumanikidza

The musana wekumanikidzwa kwejekiseni molding inofanira kugadziriswa maererano nehupfumi hwezvinhu zvakasvibiswa, yakaoma mamiriro, chigadzirwa chimiro uye unhu mamiriro. Iyo yekumashure kudzvinyirira inowanzogadziriswa pa 3-15kg / cm3. Apo chigadzirwa chepamusoro chine mhepo shoma inoputika, kusanganiswa kwemavara, shrinkage uye shanduko huru muhukuru hwechigadzirwa uye uremu, kudzvinyirira kumashure kunogona kuwedzerwa zvakakodzera. Kana muromo wadonha, mate, inonyungudika yakanyanyisa uye inoora, chigadzirwa chacho chinodzima, uye kudzoka kwezvinhu kunonoka, unogona kufunga zvakakodzera kuderedza shure kumanikidzwa.
