Yini Tinchubo Tesakhiwo Setincenye Tepulasitiki?
Yini Tinchubo Tesakhiwo Setincenye Tepulasitiki?
Lendlela yekwakha inchubo yesakhiwo setincenye tepulasitiki ikakhulukati ifaka ekhatsi kucabanga lokufana ne-geometry, kuciniseka kwebukhulu, silinganiso sekudvweba, bukhali bemhlabatsi, bukhulu belubondza, i-angle yeluhlaka, bubanti bembobo, i-fillet radii, i-angle yeluhlaka lwesikhunta, kanye netimbambo tekucinisa. Lendzatjana itawuchaza kabanti ngalinye lalamaphuzu futsi ikhulume ngekutsi tingalungiswa njani letintfo ngesikhatsi senkambo ye thermoforming kwenta ncono lizinga lemkhicito kanye nekusebenta kahle kwekukhicita.
1. I-Geometry kanye neKunemba Kwetilinganiso
Kusukela kushisa kwepulasitiki yindlela yekucubungula yesibili, ikakhulukati ekwakhiweni kwe vacuum, kuvame kuba nesikhala emkhatsini welishidi lepulasitiki kanye nesikhunta. Ngekwengeta, kuncipha kanye nekugucuka, ikakhulu etindzaweni letiphumile, kungenta kutsi lubondza lube mncane, lokuholela ekuncipheni kwemandla. Ngako-ke, tincenye tepulasitiki letisetjentiswa ekwakhiweni kwe-vacuum akukafaneli tibe netidzingo leticinile kakhulu te-geometry kanye nekunemba kwebukhulu.
Ngesikhatsi senchubo yekwakha, lelishidi lepulasitiki lelishisako lisesimeni sekwelula lesingavinjelwa, lokungaholela ekugobeni. Kuhlanganiswa nekupholisa lokukhulu kanye nekuncipha ngemuva kwekukhipha, tilinganiso tekugcina kanye nekwakheka kwemkhicito kungaba kungasimami ngenca yekushisa kanye netingucuko temvelo. Ngalesi sizatfu, tincenye tepulasitiki letishisako atifaneleki kusetjentiswa kwekubumba lokunembile.
2. Dvweba Silinganiso
Silinganiso sekudvweba, lokusilinganiso sekuphakama kwalencenye (noma kujula) kuya ebubanti bayo (noma bubanti), kakhulu kuncuma bumatima benchubo yekwakha. Lapho silinganiso sekudvweba sikhulu, inchubo yekubumba iba lukhuni kakhulu, futsi ematfuba lamakhulu etindzaba letingatsandzeki letifana nekushwaphana noma kudzabuka. Emazinga ekudvweba ngekweqile anciphisa kakhulu emandla kanye nekucina kwalencenye. Ngakoke, ekukhiciteni mbamba, libanga lelingaphansi kwesilinganiso lesikhulu sekudvweba livame kusetjentiswa, kuvame kuba emkhatsini wa 0.5 na 1.
Lesilinganiso sekudvweba sihlobene ngco nebuncane belubondza lwengxenye. Silinganiso lesincane sekudvweba singakha tindvonga letindze, letilungele kwakha emashidi lamancane, kantsi silinganiso lesikhulu sekudvweba sidzinga emashidi lamancane kwentela kucinisekisa kutsi bukhulu belubondza abubi mncane kakhulu. Ngetulu kwaloko, silinganiso sekudvweba siphindze sihlobane ne-angle yeluhlaka lwesikhunta kanye nekwelula kwetintfo tepulasitiki. Kucinisekisa lizinga lemkhicito, silinganiso sekudvweba kumele silawulwe kugwema kukhula kwelizinga lekulahla.
3. Umklamo we-Fillet
Emakhona lakhaliphile akukafaneli aklanywe emakhoneni noma emaphethelweni etincenye tepulasitiki. Esikhundleni saloko, kumele kusetjentiswe i-fillet lenkhulu ngendlela lekhonakala ngayo, nge radius yekhoneni ngalokuvamile ingabi ncane kunetikhatsi letingu 4 kuya ku 5 tebukhulu belishidi. Kwehluleka kwenta kanjalo kungabangela kucedza kwetintfo kanye nekucindzeteleka lokugcila, lokutsintsa kabi emandla alencenye kanye nekucina.
4. Engela Yeluhlaka
Kubumba ngekushisa tikhunta, letifana netikhunta letivamile, tidzinga i-angle letsite yeluhlaka kwentela kwenta lula kukhipha. I-angle yeluhlaka ivame kusuka ku 1° kuya ku 4°. I-angle lencane yeluhlaka ingasetjentiswa kuma molds lasikati, njengoba kuncipha kwencenye yepulasitiki kuniketa lokunye lokungetiwe, kwenta kukhipha kubelula.
5. Umklamo Wembambo Wekucinisa
Emashidi epulasitiki lakhiwe ngekushisa avame kuba mncane kakhulu, futsi inchubo yekwakha ilinganiselwe ngesilinganiso sekudvweba. Ngakoke, kwengeta timbambo tekucinisa etindzaweni letibutsakatsaka ngekwesakhiwo kuyindlela lebalulekile yekukhulisa kucina kanye nemandla. Kubekwa kwetimbambo tekucinisa kumele kucatshangelwe kahle kwentela kugwema tindzawo letincane kakhulu ngephansi kanye nasemakhoneni alencenye.
Ngekwengeta, kwengeta ema grooves langajulile, emaphethini, noma emamaki phansi kweligobolondvo le thermoformed kungenta kutsi kube nekucina futsi kusekele lesakhiwo. Ema grooves langajulile landze emaceleni akhulisa kucina lokumile, kantsi ema grooves langajulile landlulako, noma akhulisa kumelana nekuwa, kungenta kukhipha kube lukhuni kakhulu.
6. Kuncipha Kwemkhicito
Imikhicito leyakhiwe ngekushisa ngalokuvamile uhlangabetana nekuncipha lokukhulu, nga 50% wayo lokwenteka ngesikhatsi sekupholisa esikhunjini. Uma lizinga lekushisa lesikhunta liphakeme, lencenye ingancipha nga 25% lowengetiwe njengoba ipholile kuya ekushiseni kweligumbi ngemuva kwekukhipha sikhunta, nge 25% lesele yekuncipha kwenteka emahoreni lamashumi lamabili nakune lalandzelako. Ngetulu kwaloko, imikhicito leyakhiwe kusetjentiswa tikhunta tesifazane ivame kuba nesilinganiso sekuncipha 25% kuya ku 50% ngetulu kwaleyo leyakhiwe ngetikhunta letindvuna. Ngakoke, kubalulekile kucabanga ngekuncipha ngesikhatsi senchubo yekuklama kwentela kucinisekisa kutsi tilinganiso tekugcina tihlangabetana netidzingo tekunemba.
Ngekwenta kahle umklamo we geometry, silinganiso sekudvweba, umkhawulo we fillet, i-angle yeluhlaka, timbambo tekucinisa, kanye nekuncipha, lizinga kanye nekusimama kwetincenye tepulasitiki letishisako kungentiwa ncono kakhulu. Letintfo tekwakha inchubo tinemtselela lomcoka ekusebenteni kahle kwekukhicita kanye nekusebenta kwemikhicito lekhicitwa ngekushisa futsi tibalulekile ekucinisekiseni kutsi imikhicito ihlangabetana netidzingo temsebentisi.
