Ngowuphi uMahluko phakathi koKubumba iVacuum, iThermoforming, kunye nokuFometha koxinzelelo?

Thermoforming yinkqubo yokuvelisa apho i-sheet yeplastiki ifudunyezwa ibe yimo eguquguqukayo, ethi ibunjwe okanye ibunjwe ngokusebenzisa i-mold, kwaye emva koko ilungiswe ukwenza inxalenye yokugqibela okanye imveliso. Zombini ukwenza i-vacuum kunye nokwenza uxinzelelo ziintlobo ezahlukeneyo zeenkqubo ze-thermoforming. Umahluko omkhulu phakathi kokwenza uxinzelelo kunye nokwakhiwa kwe-vacuum linani lokubumba elisetyenzisiweyo.

Ukwenza ivacuum lolona hlobo lulula lweplastiki ye-thermoforming kwaye isebenzisa i-mold kunye noxinzelelo lwe-vacuum ukufezekisa inxalenye efunekayo yejometri. Ilungele iindawo ezifuna ukumila ngendlela echanekileyo kwicala elinye, njengokupakishwa kwecontour yokutya okanye i-elektroniki.

Kukho iintlobo ezimbini ezisisiseko zokubumba-indoda okanye i-positive (eyi-convex) kunye nebhinqa okanye i-negative, e-concave. Ukubumba kwamadoda, i-plastic sheet ifakwe kwi-mold ukwenza i-outline yemilinganiselo yangaphakathi yenxalenye yeplastiki. Kwi-molds yabasetyhini, amaphepha e-thermoplastic afakwe ngaphakathi kwi-mold ukuze enze ngokuchanekileyo imilinganiselo yangaphandle yenxalenye.

Ekwenzeni uxinzelelo , iphepha leplastiki elifudumeleyo licinezelwe phakathi kweembumba ezimbini (kungoko igama), kunokuba litsalwe malunga nokungunda okunye ngokufunxa. Ukubunjwa koxinzelelo kulungele ukwenza iinxalenye zeplastiki okanye iziqwenga ezifuna ukumila ngokuthe ngqo ngakumbi kumacala omabini kwaye/okanye zifuna umzobo onzulu (kufuneka zandise ngakumbi/nzulu zibe ngumngundo), ezifana nezingxobo zesixhobo ezifuna ukubonakala zithandeka. kumphandle kwaye snap endaweni okanye ilingane ubungakanani obuchanekileyo kwicala langaphakathi.
