Izizathu eziphambili zemigca ye-weld zezi: xa iplastiki etyhidiweyo idibana nokufakwa, imingxuma, iindawo ezinesantya esingapheliyo sokuhamba okanye iindawo ezinokuphazamiseka kokuzaliswa kokuhamba kwi-mold cavity, ukudibanisa kwezinto ezininzi ezinyibilikayo;Xa ukuzaliswa kwe-mold injection yesango kwenzeka, izixhobo azikwazi ukuxutywa ngokupheleleyo.Umzekelo, iqokobhe lesixhobo sombane,iqokobhe irayisi cooker, umatshini wesandwich iqokobhe leplastiki, isihlangu seeplastiki,imoto OEM bumper ngaphambili, njl. Okulandelayo, siya kubelana ngezizathu ezithile kunye nezisombululo ezihambelanayo zemigca ye-weld.
1. Ubushushu buphantsi kakhulu
Iqondo eliphantsi lokunyibilika linokungaqhubi kakuhle kunye nokusebenza kokudibanisa kwaye kulula ukwenza imigca ye-weld.Kulo mba, ubushushu bombhobho kunye nombhobho unokunyuswa ngokufanelekileyo okanye umjikelo we-injection unokwandiswa ukukhuthaza ukunyuka kweqondo lokushisa.Ngelo xesha, inani elidlulayo lamanzi okupholisa kwi-mold kufuneka lilawulwe kwaye ukushisa kwe-mold kufuneka kwandiswe ngokufanelekileyo.
2. Iziphene zokungunda
Iiparamitha zesakhiwo senkqubo yokuthulula i-mold inempembelelo enkulu kwimeko yokudibanisa kwezinto ezityhidiweyo, kuba ukudibanisa okungahambi kakuhle kubangelwa kakhulu ukuguqulwa kunye nokudibanisa kwezinto ezityhidiweyo.Ngoko ke, ifom yesango ene-diversion encinci kufuneka yamkelwe ngokusemandleni kwaye indawo yesango kufuneka ikhethwe ngokufanelekileyo ukuze kugwenywe izinga lokuzaliswa kwesikhunta esingahambelaniyo kunye nokuphazamiseka kokuhamba kwezinto zokubumba.Ukuba kunokwenzeka, isango elinye iphuzu kufuneka likhethwe, kuba eli sango alivelisi imilambo emininzi yezinto eziphathekayo, kwaye izinto ezityhidiweyo aziyi kudibanisa ukusuka kumacala amabini, okulula ukuphepha amanqaku e-weld.
3. Ukukhupha ngundo okungalunganga
Emva kokuba olu hlobo lwesiphoso lwenzeka, okokuqala, khangela ukuba umngxuma wokukhupha wesikhunta uvaliwe yimveliso eqinisiweyo yezinto ezityhidiweyo okanye ezinye izinto, nokuba kukho into yangaphandle esangweni.Ukuba indawo ye-carbonation isabonakala emva kokuba i-blockage isusiwe, umngxuma wokukhupha kufuneka wongezwe kwindawo yokuqokelela ukufa.Inokukhawuleziswa ngokubeka kwakhona isango okanye ngokufanelekileyo ukunciphisa amandla okuvala kunye nokwandisa i-gap yokukhupha.Ngokumalunga nokusebenza kwenkqubo, amanyathelo ancedisayo afana nokunciphisa ubushushu bezinto eziphathekayo kunye nobushushu bokubumba, ukunciphisa ixesha lokutofa ngoxinzelelo oluphezulu kunye nokunciphisa uxinzelelo lwenaliti nalo lunokuthathwa.
4. Ukusetyenziswa ngokungafanelekanga kwe-arhente yokukhulula
Ukukhutshwa kokungunda okuninzi kakhulu okanye iindidi ezingachanekanga ziya kubangela amanqaku e-weld kumphezulu wamalungu eplastiki.Ekubunjweni kwesitofu, inani elincinci le-arhente yokukhulula lisetyenziswa ngokulinganayo kuphela kwiindawo ekungelula ukuba zenziwe, njengemicu.inaliti yeplastiki yesiko PA6 nut）Ngokomgaqo, inani le-arhente yokukhululwa kufuneka lincitshiswe.Ukukhethwa kwee-agent ezahlukeneyo zokukhululwa kufuneka kunqunywe ngokwemiqathango yokubumba, imilo yeengxenye zeplastiki kunye neentlobo zezinto eziluhlaza.
5. Uyilo lwesakhiwo seplastiki esingenangqiqo
Ukuba ubukhulu bodonga lweendawo zeplastiki zenziwe zincinci kakhulu, kunokubakho umahluko omkhulu kubukhulu kunye nokufakwa okuninzi kakhulu, okuya kubangela ukudibanisa kakubi.Ke ngoko, xa uyila ubume bemilo yeengxenye zeplastiki, kufuneka kuqinisekiswe ukuba eyona nxalenye incinci yamacandelo eplastiki kufuneka ibe nkulu kunobunzima obuncinci bodonga obuvunyelwe ngexesha lokubumba.Ukongezelela, ukusetyenziswa kokufakwa kufuneka kuncitshiswe kwaye ubukhulu bodonga kufuneka bufane ngokusemandleni.
