Iyini i-Thermoforming Mold?
Izinhlobo Zezikhunta Zokwenza I-Thermoforming
Izikhunta ezisebenzisa i-thermoforming zingahlukaniswa kabanzi ngezigaba ezimbili: izikhunta zesilisa (izikhunta ezinhle) kanye nezikhunta zesifazane (izikhunta ezimbi).
Isikhunta Sesilisa
Isikhunta sesilisa, esaziwa nangokuthi isikhunta esisiza nge-plug-assist, sinomumo ophakanyisiwe lapho kufakwa khona ishidi le-thermoplastic. Lolu hlobo lwesikhunta luwusizo uma kudingeka imininingwane yangaphakathi noma ukuthungwa kwendawo kumkhiqizo. Isikhunta sesilisa sivame ukusetshenziswa ezisetshenziswa lapho ukufana kobukhulu bodonga kubalulekile.
Isikhunta Sabesifazane
Isikhunta sesifazane, esaziwa nangokuthi isikhunta esingaphakathi, sinesimo esigoqekile lapho kucindezelwa khona ishidi le-thermoplastic. Lolu hlobo lwesikhunta lufanele ukusetshenziswa lapho kudingeka khona ukuthungwa okuningiliziwe kobuso ngaphandle komkhiqizo. Isikhunta sesifazane sivame ukusetshenziswa ukukhiqiza izinto ezifana namathileyi, izivalo, kanye nezitsha zokupakisha.
Izinto Zokubumba Ezisebenzisa I-Thermoforming
Ngenxa yokuthi i-thermoforming ayibandakanyi ukucindezela okuphezulu futhi ukuma kwezingxenye kulula, ukucindezela okusetshenziswa ku-mold kuphansi, futhi i-mold ayidingi ukuqina okuphezulu kakhulu. Izikhunta ze-thermoforming zingenziwa ngezinto ezahlukahlukene njengokhuni (ukhuni oluqinile nokhuni olucindezelwe), i-plaster, ipulasitiki (i-phenolic resin, i-epoxy resin, njll.), insimbi, kanye ne-aluminium alloys.
Yiziphi Izindlela Zokuvikela Ukungagqwali Ezisetshenziswa Eziteshini Zokupholisa Ezikhunjini Ezisebenzisa I-Thermoforming?
Inhloso yokuvikela ukugqwala ezikhumbeni ezisebenzisa i-thermoforming iwukugcina ikhono lokudlulisa ukushisa kwesikhunta. Ezikhumbeni ezisebenzisa i-thermoforming, izinga lokushisa lamanzi lisukela ku-5–150°C. Ngaphansi kwezimo ezijwayelekile, amanzi angabangela amazinga ahlukahlukene omonakalo wokugqwala esikhumbeni. Izindlela zokuvikela ukugqwala ezilandelayo zisetshenziselwa ukupholisa iziteshi ezikhumbeni ezisebenzisa i-thermoforming:
Qaphela ngesikhathi sokuklama nokukhiqiza isikhunta ukuze uvimbele i-aluminium nethusi ukuthi zingathintani ngqo emiseleni yamanzi. Ukuthintana ngqo kwe-aluminium nethusi kungabangela ukugqwala kwe-aluminium kalula. Isehlukanisi sensimbi engagqwali noma sepulasitiki okungenani esingama-30 cm ubude kumele sifakwe phakathi kwe-aluminium nethusi.
Uma izindonga zesikhunta zincane (zihlukanisa i-baffle zibe izingxenye ngazinye), njengoba kuvamile ezimweni ezivamile zokwakha kanye nasezikhumbeni zokusika zemishini ye-thermoforming ezenzakalelayo, kunconywa ukufaka ama-anode e-magnesium angenamandla emiseleni yamanzi.
Uma kusungulwa uhlelo lokupholisa, uma kungenzeka, ingxenye enqamulayo kufanele yenziwe ibe nkulu ngangokunokwenzeka ukuze ijubane lamanzi lingadluli ku-1.5 m/s. Ijubane lamanzi eliphezulu lingaholela ekugugulekeni okugugulekayo.
Ngaphambi kokusetshenziswa kwesikhunta, imisele yamanzi kumele ihlanzwe ngokucophelela. Uma kungenzeka, qala ngokufutha kahle ngomoya kuzo zombili izinhlangothi, bese usebenzisa amanzi ukuhlola ukuvuza bese ugeza ngemva kwalokho. Kubaluleke kakhulu ukusebenzisa isihlungi ukuqinisekisa ukuhlanzeka kwesekethe yesikhunta noma ipompo, bese ekugcineni ufutha ngomoya.
Kunconywa ukusebenzisa indawo yokupholisa enezinga eliphezulu lezithibi zokugqwala. Ukuhlushwa okudingekayo kuncike ohlotsheni lwesithibi esisetshenzisiwe.
