Ka'idar Vacuum Forming Machine: Vacuum forming kuma ana kiransa thermoplastic forming, Wannan tsari ya haɗa da dumama da laushin zanen gadon thermoplastic (misali, PVC, PET, PP) da yin amfani da famfo don siffata su sama da gyare-gyare, samar da abubuwa kamar murfin da aka kafa, blister trays, da clamshell packaging.
Injin ƙirƙira Vacuum ya haɗa da sassa da yawa kamar tsarin clamping, tsarin dumama, injin daɗaɗɗen iska da tsarin iska da mold.
Lokacin da aka yi gyare-gyare na filastik, ana gyara takardar akan na'urar matsawa. A cikin thermoforming na janar-manufa da kuma hadawa thermoforming inji ana amfani da su sauƙaƙe da kayyade daban-daban masu girma dabam na takardar clamping na'urar. A wasu lokuta, duk injin ɗin ana sanye shi da saitin firam ɗin matsewa.
Ya kamata a inganta tsarin matsawa tare da sarrafawa mai sarrafa kansa don cimma saurin aiki, don haka haɓaka ingancin sashi da ingantaccen samarwa.
Thermoplastic takardar da fim na injin kafa tsari, daya daga cikin manyan matakai ne sheet heater.Heating duration da kuma tasiri dogara a kan dalilai ciki har da hita zane, radiation surface thermal inertia, takardar-to-heater nesa, abu sha coefficients, da kuma abu ta thermophysical Properties. Na'urorin dumama da aka fi amfani da su sune masu dumama wutar lantarki, masu fitar da kristal da masu dumama infrared.
Tsarin injin ya ƙunshi famfo famfo, tankuna, bawuloli, bututu da ma'auni, da sauransu, galibi ana amfani da su a cikin injin samar da nau'in injin famfo daban, injin famfo irin wannan ya kamata ya kai 0.07 ~ 0.09 Mpa (520mmHg) ko fiye. Tankin ajiyar iskar gas gabaɗaya akwatin siliki ne wanda aka yi masa walda da faranti na ƙarfe na bakin ciki kuma yana da ƙasan kwanuka. Ƙarfin tankin ajiyar iskar gas ya kamata ya zama aƙalla rabin ƙarfin babban ɗakin gyare-gyare. Dole ne a sanye da bututun injin da ya dace don sarrafa kunkuntar damar injin.
Ƙarfin motar injin famfo (yawanci 2-4 kW don manyan / tsarin sauri) an ƙaddara ta girman kayan aiki da buƙatun samarwa. Bututun bututu suna buƙatar madaidaitan bawuloli masu sarrafa kwarara. Girman tsarin tsakiya na injin ya dogara da takamaiman samarwa da buƙatun haɓaka masana'anta.
Tsarin pneumatic ya ƙunshi compressors, tankunan iska, bawuloli, da bututu. Injunan gyare-gyare yawanci suna buƙatar matsewar iska mai nauyin 0.4-0.5 MPa, wanda aka samar ko dai ta hanyar haɗaɗɗen kwamfarar piston ko na'urar dunƙulewar shuka ta tsakiya. Hakanan za'a iya amfani da babban dunƙule iska kwampreso dukan shuka wadata.
matsawa iska ban da babban adadin ya kamata a yi amfani da kafa, akwai lokacin da wani ɓangare na mold na farko kayayyakin waje da sanyaya da magudi na mold frame da Gudun takardar da sauran inji sassa kamar ikon aiki.
Don inganta haɓakar samarwa, ana buƙatar samfuran ƙirƙira don sanyaya su kafin tarwatsawa. Da kyau, sassan ciki da na waje na sassan da ke hulɗa da ƙirar suna sanyaya, kuma yana da kyau a yi amfani da gyare-gyare tare da coils na ciki. Don gyare-gyaren da ba na ƙarfe ba, irin su itace, filasta, filayen filastik ƙarfafa robobi, resin epoxy da sauran gyare-gyare, saboda ba zai yiwu a yi amfani da sanyaya ruwa ba, za a iya canza shi zuwa iska mai sanyaya, kuma ana iya ƙarawa a cikin hazo na ruwa don kwantar da farfajiyar waje na wuraren da aka kafa.
Sanyaya yanayi yana samar da sassan da aka kawar da damuwa tare da ingantaccen juriya mai tasiri. Yayin da sanyaya ruwa yana ƙara yawan aiki, yana iya haifar da matsananciyar damuwa na ciki.
Rushewa ya haɗa da fitar da samfurin daga ƙirar, wanda ƙila ya zama maɗaukaki ko maɗaukaki. A mafi yawan lokuta, ƙanƙanwar zafi yana haifar da ɓangaren don mannewa da ƙura. Don haka ana samun gyare-gyare ta hanyar amfani da juzu'i na iska ta hanyar tashar jiragen ruwa ko tasoshin iska da aka matsa.
Musamman ga molds tare da karamin saki ko tare da ccave molds, ana kuma sakawa ta hanyar amfani da takardar sakin a kan takardar tare da maganin tero tare da maganin Teeflon.
Tsarin sarrafawa gabaɗaya ya haɗa da ƙira, ƙarewa da sauran matakai, gami da na'urori, mita, bututu, bawuloli da sigogi masu sarrafawa da hanyoyin kunnawa. Hanyoyin sarrafawa sune manual, electromechanical atomatik iko, sarrafa kwamfuta, da dai sauransu.
