Ziziphi iiNkqubo zoLwakhiwo lwaMalungu ePlastiki?
Uyilo lwenkqubo yolwakhiwo lwamalungu eplastiki ikakhulu lubandakanya ukuqwalaselwa okunje ngejometri, ukuchaneka komda, umlinganiselo wokuzoba, uburhabaxa bomphezulu, ubukhulu bodonga, i-engile eyidrafti, idiameter yomngxuma, i-fillet radii, i-engile yokubumba, kunye neembambo zokuqinisa. Eli nqaku liza kucacisa nganye kwezi ngongoma kwaye lixoxe ngendlela yokwandisa ezi zinto ngexesha lenkqubo ye-thermoforming ukuphucula umgangatho wemveliso kunye nokusebenza kakuhle kwemveliso.
1. Ijometri kunye nokuchaneka koMda
Ukusukela oko iplastiki ye-thermoforming yindlela yokucubungula yesibini, ngakumbi ekwenzeni i-vacuum, kuhlala kukho umsantsa phakathi kwephepha leplastiki kunye nokungunda. Ukongezelela, i-shrinkage kunye ne-deformation, ngokukodwa kwiindawo eziphumayo, zinokubangela ukuba ubukhulu bodonga bube buncinci, obukhokelela ekunciphiseni kwamandla. Ke ngoko, iinxalenye zeplastiki ezisetyenziselwa ukwenza ivacuum akufuneki zibe neemfuno ezingqongqo kwijometri kunye nokuchaneka komda.
Ngethuba lenkqubo yokuqulunqa, iphepha leplastiki elivuthayo likwimeko yokwelula engathinteliyo, enokukhokelela ekudakaleni. Idityaniswe nokupholisa okubalulekileyo kunye nokuncipha emva kokudilizwa, imilinganiselo yokugqibela kunye nokumila kwemveliso kunokungazinzi ngenxa yobushushu kunye nokutshintsha kwendalo. Ngesi sizathu, iinxalenye zeplastiki ze-thermoformed azifanelekanga kwizicelo zokubumba ezichanekileyo.
2. Zoba umlinganiselo
Umlinganiselo wokutsalwa, owumlinganiselo wobude benxalenye (okanye ubunzulu) ukuya kububanzi bayo (okanye ububanzi), ubukhulu becala bumisela ubunzima benkqubo yokwenza. Okukhona usiba mkhulu umyinge wokuzoba, kokukhona kuya kuba nzima ngakumbi inkqubo yokubumba, kwaye kokukhona amathuba okuba nemiba engafunekiyo efana nokushwabana okanye ukuqhekeka ibe mkhulu. Ubungakanani bomzobo obugqithisileyo bunciphisa kakhulu amandla kunye nokuqina kwenxalenye. Ke ngoko, kwimveliso yokwenyani, uluhlu olungaphantsi komlinganiselo wokutsalwa ngokuqhelekileyo lusetyenziswa, ngokuqhelekileyo phakathi kwe-0.5 kunye ne-1.
Umlinganiselo wokutsalwa uhambelana ngokuthe ngqo nobukhulu obuncinane bodonga lwenxalenye. Umlinganiselo omncinci wokuzoba unokudala iindonga ezityebileyo, ezilungele ukwenziwa kwephepha elincinci, ngelixa umzobo omkhulu ufuna amashiti atyebileyo ukuqinisekisa ukuba ubukhulu bodonga bungabhityi kakhulu. Ukongeza, umyinge wokuzoba unxulumene ne-engile yedrafti yokubumba kunye nokunwebeka kwezinto zeplastiki. Ukuqinisekisa umgangatho wemveliso, umlinganiselo wokudweba kufuneka ulawulwe ukuze ugweme ukunyuka kwezinga le-scrap.
3. Uyilo lweFillet
Iikona ezibukhali akufuneki zenziwe kwiikona okanye kwimiphetho yamalungu eplastiki. Endaweni yoko, i-fillet enkulu kangangoko kunokwenzeka kufuneka isetyenziswe, kunye ne-radius yekona ngokubanzi ayincinci kune-4 ukuya ku-5 ubukhulu beshidi. Ukungaphumeleli ukwenza oko kunokubangela ukuncipha kwezinto kunye nokugxininiswa koxinzelelo, kuchaphazela kakubi amandla enxalenye kunye nokuqina.
4. Drafti engile
Thermoforming ukubumba, okufana nokubumba okuqhelekileyo, kufuna i-angle eyidrafti ethile ukuququzelela ukubunjwa. I-engile eyidrafti idla ngokuqala ukusuka ku-1° ukuya ku-4°. I-angle encinci yedrafti ingasetyenziselwa ukubumba kwabasetyhini, njengoko i-shrinkage yenxalenye yeplastiki inika imvume eyongezelelweyo, ukwenza ukubunjwa kube lula.
5. Uyilo lweRib yokuQinisa
Amaphepha eplastiki e-thermoformed ahlala ebhityile kakhulu, kwaye inkqubo yokuyila inqunyelwe ngumyinge wokuzoba. Ke ngoko, ukongeza iimbambo zokuqinisa kwiindawo ezibuthathaka ngokwesakhiwo yindlela ebalulekileyo yokwandisa ubulukhuni kunye namandla. Ukubekwa kweembambo zokuqiniswa kufuneka kuqwalaselwe ngokucophelela ukuze kugwenywe iindawo ezincinci ezisezantsi kunye neekona zenxalenye.
Ukongeza, ukongeza i-grooves enzulu, iipateni, okanye amanqaku asezantsi kwiqokobhe le-thermoformed inokunyusa ukuqina kunye nokuxhasa isakhiwo. Imijelo emide emacaleni inyusa ubungqongqo obuthe nkqo, ngelixa iingcango ezinqamlezileyo ezingenzulu, nangona ziphucula ukuxhathisa ekuweni, zinokwenza ukudiliza kube nzima ngakumbi.
6. Ukuncipha kwemveliso
iimveliso Thermoformed ngokubanzi amava okucutheka okubalulekileyo, malunga nama-50% akwenzeka ngexesha lokupholisa kumngundo. Ukuba iqondo lobushushu lokungunda liphezulu, inxalenye inokucutheka nge-25% eyongezelelweyo njengoko iphola kwiqondo lobushushu begumbi emva kokudilizwa, kunye ne-25% eseleyo yokushwabana okwenzeka kwiiyure ezingama-24 ezilandelayo. Ngaphezu koko, iimveliso ezenziwe kusetyenziswa ukungunda kwabasetyhini zikholisa ukuba nesantya sokushwabana kwe-25% ukuya kwi-50% ephezulu kunezo zenziwe ngokubumba kwamadoda. Ngoko ke, kubalulekile ukuqwalasela ukucutheka ngexesha lenkqubo yoyilo ukuqinisekisa ukuba imilinganiselo yokugqibela ihlangabezana neemfuno zokuchaneka.
Ngokulungisa uyilo lwejometri, umyinge wokuzoba, i-fillet radius, i-angle yedrafti, iimbambo zokuqinisa, kunye nokuncipha, umgangatho kunye nokuzinza kweengxenye zeplastiki ze-thermoformed zingaphuculwa kakhulu. Le miba yoyilo lwenkqubo inefuthe elibalulekileyo kwimveliso esebenzayo kunye nokusebenza kweemveliso ze-thermoform kwaye zingundoqo ekuqinisekiseni ukuba iimveliso ziyahlangabezana neemfuno zabasebenzisi.
