Kuberako impfu zitandukanye zagiye zikoreshwa mubice byinshi, zifatanije niterambere ryubuhanga bwogukora inganda zumwuga muriyi myaka, habaye impinduka niterambere.
Kubwibyo, muri iki gice, amategeko rusange yo gushushanya ya vacuum suction molding apfa muri make.Igishushanyo mbonera cya pulasitike ya vacuum ikubiyemo ubunini bwicyiciro, ibikoresho byo kubumba, imiterere isobanutse, imiterere ya geometrike, imiterere ihagaze hamwe nubuziranenge bwubuso.
1. Kubijyanye nubunini bwikigereranyo, ibisohoka ni bito, kandi birashobora gukorwa mubiti cyangwa resin.Ariko, niba ifumbire yubushakashatsi ari ukubona amakuru ajyanye no kugabanuka, guhagarara neza, hamwe nigihe cyigihe cyibicuruzwa, ifumbire imwe ya cavity igomba gukoreshwa mubushakashatsi, kandi irashobora kwemezwa ko izakoreshwa mubihe byakozwe.Ubusanzwe ibishushanyo bikozwe muri gypsumu, umuringa, aluminium, cyangwa aluminiyumu-ibyuma, kandi aluminium-resin ikoreshwa gake.
Igishushanyo mbonera cya geometrike.Mugihe cyo gushushanya, burigihe utekereze kumurongo uhamye hamwe nubuziranenge bwubuso.Kurugero, igishushanyo mbonera cyibicuruzwa hamwe nuburinganire buringaniye bisaba gukoresha ibishushanyo byigitsina gore (ibishushanyo mbonera), ariko ibicuruzwa bifite ububengerane bwo hejuru bisaba gukoresha ibishushanyo byabagabo (mveve convex).Muri ubu buryo, umuguzi wa plastike azirikana ingingo zombi kugirango ibicuruzwa bibyare umusaruro mubihe byiza.Ubunararibonye bwerekanye ko ibishushanyo bidahuye nuburyo bwo gutunganya akenshi binanirwa.
3. Guhagarara neza.Mugihe cyo kubumba, hejuru yubuso bwigice cya plastiki hamwe nububumbyi nibyiza kuruta guhagarara kurwego rwigice gisize.Niba umubyimba wibikoresho bisabwa guhinduka mugihe kizaza bitewe nuburemere bwibikoresho, ifumbire yumugabo irashobora guhinduka muburyo bwumugore.Kwihanganira ibipimo bya plastike ntibigomba kuba munsi ya 10% yo kugabanuka.
4. Ubuso bwigice cya plastiki, nkuko ibikoresho bibumba bishobora gutwikira, imiterere yubuso bwubuso bugaragara bwigice cya plastike igomba gukorwa kugirango ihuze nububiko.Niba bishoboka, ntukore ku buso bworoshye bwa plastike hamwe nubuso.Ninkurugero rwo gukora ubwogero bwogero hamwe nigituba cyo kumesa hamwe nuburyo bubi.
5. Guhindura.Niba impande zombi zifata igice cya plastiki zerekanwe hamwe na horizontal ya horizontal, hagomba kuba byibura mm 6 kugeza 8 mm mubyerekezo byuburebure.Ibindi bikorwa byo kwambara, nko gusya, gukata laser, cyangwa jetting, nabyo bigomba kwemerera margin.Ikinyuranyo hagati yo gukata kumpande zo gukata zipfa ni ntoya, kandi ubugari bwikwirakwizwa rya punching bipfa iyo gutema nabyo ari bito.Ibi bigomba kwitabwaho.
6. Kugabanuka no guhindura ibintu.Plastike iroroshye kugabanuka (nka PE).Ibice bimwe bya plastiki biroroshye guhindura.Nuburyo bwo kubikumira, ibice bya pulasitike bizahinduka mugihe cyo gukonja.Muriyi miterere, birakenewe guhindura imiterere yububiko kugirango uhuze na geometrike itandukanijwe nigice cya plastiki.Kurugero: Nubwo urukuta rwigice cya plastiki rugumishijwe neza, ikigo cyacyo cyatandukanijwe na 10mm;shingiro shingiro irashobora kuzamurwa kugirango ihindure kugabanuka kwiyi deformasiyo.
7. Kugabanuka, ibintu bikurikira bigabanuka bigomba kwitabwaho mugihe ukora plastike ikora plastike.
①Ibicuruzwa byabumbwe bigabanuka.Niba igabanuka rya plastike ridashobora kumenyekana neza, rigomba gutorwa cyangwa kuboneka mugupimisha hamwe nuburyo bumwe.Icyitonderwa: Kugabanuka gusa birashobora kuboneka murubu buryo, kandi ingano ya deformasiyo ntishobora kuboneka.
②Kugabanuka guterwa n'ingaruka mbi zamakuru yo hagati, nka ceramics, rubber silicone, nibindi.
③Kugabanya ibikoresho bikoreshwa mubibumbano, nko kugabanuka mugihe utera aluminium.
