Umenzi ochwephesha woomatshini be-thermoforming.
1. Ufakelo
Ukumatanisa phakathi eshushu ukwenza die kunye nomatshini kubaluleke kakhulu, ngoko ke kufa kufuneka kwenziwe ngokomatshini esetyenziswa phambi kokuvula die. Ukutshintshwa kweefa rhoqo kuya kuthintelwa ngexesha lemveliso. Ngenxa yokuba ukutshintshwa kwesikhunta, akunakuphepheka ukwenza umonakalo othile ekuchanekeni kwesikhunta.
2. Ubushushu
Xa kusetyenzwa izinto ezisetyenziswa ngokuqhelekileyo (PP, PS, PVC, njalo njalo), ubushushu ngundo ngokubanzi 16-18 ℃. Kufanelekile ukukhankanya ukuba ubushushu bomngundo akufanele bube ngaphantsi kwe-10 ℃. I-Condensation iya kuchaphazela umgangatho wemveliso kwaye ikhokelela kwi-rust of mold. Umphetho wemela wokungunda yinxalenye ebalulekileyo. Ubushushu obungaguqukiyo obunxulumeneyo (± 5 ° C) kwimiphetho yemela yokungunda ephezulu nasezantsi inokwenza ukwandiswa komphetho wemela (umgaqo wokwandiswa kwe-thermal kunye nokufinyela okubandayo) kulingane. Ngaphandle koko, umphetho wemela uya kugugiswa okanye uqhekeke ngenxa yokungaqhubi kakuhle kwi-incision.
Isixokelelwano samanzi okupholisa siya kuhlolwa yonke imihla kwaye amanzi aya kutshintshwa rhoqo. Ukuba ungcoliseko lunzulu, isicoci kunye nesinyibilikisi siyakongezwa ukuze kucocwe ukunqanda ukuvalela umjelo wamanzi wokungunda.
3. Ukuthambisa
Umkhono wesikhokelo wekholamu yesikhokelo somgca uya kuthambisa kabini ngeveki; Intonga eyolulayo kunye ne-ejector rod iyakuthanjiswa rhoqo kwiiyure ezisibhozo, kwaye i-nut iya kujongwa ukuba ikhululekile; Coca i-molds ephezulu kunye nezantsi kunye nesibhamu somoya ukukhusela isikhunta ukuba sonakaliswe yimicimbi yangaphandle.
4. Ugcino
Ngaphambi kokugcinwa, susa amanzi okupholisa ashiyekileyo kumjelo wamanzi wokubumba ngomoya, uze ubeke isikhunta kwindawo eyomileyo. Ukuba ukufuma komoya kwindawo engqongileyo kuphezulu, umphezulu wokungunda kufuneka uqatywe ngeVaseline okanye utshizwe nge-anti rust agent ukuze ukhuseleke. Iimolds eziphezulu kunye nezisezantsi ziya kubekwa ngokwahlukileyo kangangoko kunokwenzeka, kwaye intonga ye-ejector kunye nentonga eyolulayo iya kunyuka ngokuthe nkqo ukuthintela ukuguqulwa kwesikhunta. Ukuba iimeko azivumi, ibhodi ethe ngqo iya kudityaniswa phakathi kweengqameko zeemela ezingaphezulu kunye nezisezantsi zokubumba ukuphepha umonakalo kwimida yemela.
5. Ukusetyenziswa kunye nokugcinwa kwedayiti eshushu yokwenza ngumsebenzi wamava, ekufuneka ube nobuchule kwaye ube namava.
Imveliso ngoku yamkelwe ngokubanzi phakathi kwabathengi kwaye inesicelo esibanzi kwimarike.
Umenzi ochwephesha woomatshini be-thermoforming.
