Faka ukungunda ngokubanzi luhlobo lokungunda elenza amandongomane, iinxalenye zentsimbi okanye iinxalenye zeplastiki eziqinileyo ezimiliselwe ngaphakathi kwimingxuma yokubumba inaliti.
I-DJmolding ibonelela ngenkonzo yokubumba inaliti ye-mlod kwimakethi yaseIndiya, kwaye sivelisa iindawo ezininzi zeplastiki zokubumba kumashishini ahlukeneyo, ngakumbi abenzi bezixhobo zasekhaya. Abanye abavelisi bezixhobo zasekhaya zaseIndiya bathenga iinxalenye zeplastiki zokubumba ixesha elide i-DJmolding. Sinobudlelwane obuhle kakhulu nezi nkampani zaseIndiya.
Faka isitofu sokubumba amantongomane: izinto zamandongomane zinokuba yintsimbi engatyiwa, ubhedu, ubhedu kunye nentsimbi, ngokuqhelekileyo kusetyenziswa amandongomane obhedu. Ubhedu kulula ukugquma, nto leyo enceda amandongomane kunye neeplastiki zidibanise kakuhle. Ukunyamezelana kwe-nut bores yangaphakathi kufuneka kulawulwe ngaphakathi kwe-0.02mm, kungenjalo kubangele ukukhanya ukuba ukunyamezela ngaphaya kwe-0.02mm. Ekufakeni isikhunta, kufuneka udibanise amantongomane kwizikhonkwane zokufaka ukuvavanya. Ukuba iqinile phakathi kwamantongomane kunye nezikhonkwane, kuya kuba nzima ukukhupha inxalenye kwaye kubangele amanqaku okukhupha okanye iingxaki zokuncamathela. Ukuba ayilunganga, inokubangela ukukhanya.
Faka intsimbi yokubumba isitofu:
Amalungu esinyithi anokuba yintsimbi engatyiwa, ialuminiyam, ubhedu, intsimbi ... njl. Ukunyamezela kweengxenye zetsimbi kufuneka kulawulwe ngaphakathi kwe-0.02mm, ngaphandle koko kunzima ukutywina izinto kwaye kulula ukuba ne-flash. I-acreage yeendawo zetsimbi ayinakuyilwa ibe nkulu kakhulu.
Ukuba i-acreage yokuzalisa yamalungu esinyithi inkulu kakhulu, kuya kuba nzima kakhulu ukufikelela ngokujovwa ngokupheleleyo njengomahluko omkhulu wobushushu phakathi kwamalungu esinyithi. Iindawo zentsimbi zidla ngokuyilwa emngxunyeni njengoko umngxuma ungashukumi, nto leyo enceda ukunqanda isiphumo sodanyazi olusuka kumalungu esinyithi aphumayo xa ehamba (kwimeko embi kakhulu, inokonakalisa ukungunda). Kwiimeko ezithile, izikhundla zeengxenye zetsimbi zinokuthi ziyilwe kuphela kwindawo engundoqo okanye kwicala lemveliso.
Faka ukubumba ngenaliti yeplastiki eqinile:
Ngokuqhelekileyo khetha iiplastiki eziqinileyo ezinezinga eliphezulu lokunyibilika, njenge-PEEK, PA66+30GF, PP+30GF, PA12+30GF, PPS….etc. Ukunyamezela kwezi plastiki ezinzima kufuneka kuchaneke.
