Umgomo Wokuklama Wesikhunta

Ngenxa yokuthi ukufa kokubumba okuhlukahlukene kuye kwasetshenziswa emikhakheni eminingi, kuhambisana nokuthuthukiswa kobuchwepheshe bokukhiqiza isikhunta kule minyaka, kube nezinguquko nentuthuko ethile.

Ngakho-ke, kulesi sigaba, imithetho yokuklama evamile yokufa kwe-vacuum suction molding ifinyezwa.Idizayini yesikhunta se-vacuum yokubumba ipulasitiki ihlanganisa usayizi weqoqo, okokusebenza kokubumba, izimo zokunemba, ukwakheka komumo wejometri, ukuzinza kwe-dimensional kanye nekhwalithi yendawo.

1. Ngokuhlolwa kosayizi we-batch, ukuphuma kwesikhunta kuncane, futhi kungenziwa ngokhuni noma nge-resin.Kodwa-ke, uma isikhunta sokuhlola siwukuthola idatha mayelana nokushwabana, ukuzinza kwe-dimensional, kanye nesikhathi somjikelezo womkhiqizo, isikhunta esisodwa somgodi kufanele sisetshenziselwe ukuhlolwa, futhi singaqinisekiswa ukuthi sisetshenziswa ngaphansi kwezimo zokukhiqiza.Isikhunta ngokuvamile senziwe nge-gypsum, ithusi, i-aluminium, noma ama-alloys ensimbi ye-aluminium, kanti i-aluminium-resin ayivamisile ukusetshenziswa.

2. Ukwakheka komumo weJiyomethri.Lapho uklama, hlala ucabangela ukuzinza kwe-dimensional nekhwalithi yendawo.Isibonelo, ukuklama komkhiqizo nokuzinza kwe-dimensional kudinga ukusetshenziswa kwesikhunta sesifazane (isikhunta se-concave), kodwa imikhiqizo ene-gloss yendawo ephakeme idinga ukusetshenziswa kwesikhunta samadoda (isikhunta esi-convex).Ngale ndlela, umthengi wepulasitiki uzocabangela kokubili Iphuzu ukuze umkhiqizo ukhiqizwa ngaphansi kwezimo ezifanele.Okuhlangenwe nakho kufakazele ukuthi imiklamo engahlangabezani nezimo zangempela zokucubungula ngokuvamile ihluleka.

3. Ukuzinza kwe-Dimensional.Phakathi nenqubo yokubumba, indawo yokuxhumana yengxenye yepulasitiki enesikhunta ingcono kunokuzinza kwengxenye eshiya isikhunta.Uma ukushuba kwezinto kudingekile ukuthi kushintshwe esikhathini esizayo ngenxa yokuqina kwento, isikhunta sowesilisa singaguqulwa sibe isikhunta sesifazane.Ukubekezelelana kobukhulu bezingxenye zepulasitiki akumele kube ngaphansi kuka-10% wokuncipha.

4. Ubuso bengxenye yepulasitiki, kuze kube yilapho izinto zokubumba zingamboza, isakhiwo esingaphezulu sendawo ebonakalayo yengxenye yepulasitiki kufanele sakhiwe ngokuthintana nesikhunta.Uma kungenzeka, ungathinti indawo ebushelelezi yengxenye yepulasitiki ne-mold surface.Kufana nendaba yokwenza obhavu namabhavu okuwasha anesikhunta esingesihle.

5. Ukuguqulwa.Uma unqenqema olubambekayo lwengxenye yepulasitiki lugawulwe ngesaha elivundlile lomshini, kufanele okungenani kube no-6 kuya ku-8 mm ubude.Omunye umsebenzi wokugqoka, njengokugaya, ukusika i-laser, noma i-jetting, kufanele futhi uvumele umkhawulo.Igebe eliphakathi kwamaphethelo wokusika we-cutting edge die lincane kakhulu, futhi ububanzi bokusabalalisa kokushaya ngokufa lapho ukusika nakho kuncane.Lezi kufanele zinakwe.

6. Ukuncipha kanye nokuguqulwa.Amapulasitiki kulula ukuwashwabadela (njenge-PE).Ezinye izingxenye zepulasitiki kulula ukonakala.Kungakhathaliseki ukuthi zingavinjelwa kanjani, izingxenye zepulasitiki zizokhubazeka ngesikhathi sokupholisa.Ngaphansi kwalesi simo, kuyadingeka ukushintsha ukuma kwesikhunta sokwenza ukuze uvumelane nokuphambuka kwejometri yengxenye yepulasitiki.Isibonelo: Nakuba udonga lwengxenye yepulasitiki lugcinwa luqondile, isikhungo salo sokubhekisela sichezuke ngo-10mm;isisekelo sesikhunta singaphakanyiswa ukuze kulungiswe ukuncipha kwalokhu kuguqulwa.

7. Ukuncipha, izici ezilandelayo zokushwabana kufanele zicatshangelwe lapho kukhiqizwa isikhunta esakha ipulasitiki.

Umkhiqizo obunjiwe uyashwabana.Uma ukushwabana kwepulasitiki kungaziwa ngokucacile, kufanele kuthathwe isampula noma kutholwe ngokuhlolwa ngesikhunta esimise ngendlela efanayo.Qaphela: Ukuncipha kuphela okungatholwa ngale ndlela, futhi usayizi wokuguqula awukwazi ukutholwa.

Ukuncipha okubangelwa imiphumela emibi yemidiya emaphakathi, njenge-ceramics, irabha ye-silicone, njll.

Ukuncipha kwezinto ezisetshenziswa ekubunjweni, njengokushwabana uma uphonsa i-aluminium.
