Txhaj Tshuaj Molding Yog Dab Tsi?

Kev txhaj tshuaj yog dab tsi? Kev txhaj tshuaj molding yog cov txheej txheem tsim feem ntau siv rau kev tsim cov khoom los ntawm cov yas ua khoom plig thiab cov khoom ua si rau lub cev tsheb, khoom siv xov tooj ntawm tes, dej fwj, thiab ntim khoom. Qhov tseem ceeb ntau ntau yam ntawm cov yas uas peb siv nyob rau hauv txhua txhua hnub lub neej yog txhaj tshuaj pwm. Nws yog cov txheej txheem nrawm los tsim cov khoom loj ntawm cov khoom seem yas. Qhov hloov pauv ntawm cov duab thiab qhov loj me tuaj yeem los ntawm kev siv txhaj tshuaj molding tau xwm yeem nthuav dav qhov ciaj ciam ntawm cov qauv hauv plastics thiab tso cai ntau qhov kev hloov pauv rau cov ntaub ntawv ib txwm vim kev tsim qauv kev ywj pheej thiab lub teeb yuag.

Lub tshuab txhaj tshuaj yog tsim los ntawm peb qhov khoom tseem ceeb - feed hopper, ntsia hlau, thiab lub thoob ua kom sov. Yas granules rau ib feem tau pub rau hauv cov tais ua kom sov los ntawm kev cia siab. Cov yas uas tau muab tso rau hauv lub plhaw yog feem ntau hauv cov hmoov lossis cov ntaub ntawv txawm hais tias qee cov resins, piv txwv li, roj hmab silicone, tej zaum muaj kua thiab tej zaum yuav tsis ua rau muaj cua sov. Cov khoom siv no ces yaj tau siv siv qhov kev sib txhuam ntawm qhov muaj txiaj ntsig cov ntsia hlau ua ke nrog cov rhaub kab. Cov yas molten yog tom qab ntawd txhaj rau los ntawm lub nozzle thiab mus rau hauv cov kab noj hniav pwm - nws yuav zoo li yooj yim, tab sis kev txhaj tshuaj molding yog qhov kev ua cov txheej txheem heev. Thaum nyob hauv pwm kab noj hniav, cov khoom txias thiab solidifies rau qhov teeb tsa ntawm cov kab noj hniav. Thaum cov ntu ua qhov nyuaj, txav ntawm lub platen uas tuaj yeem qhib lub pwm thiab cov ntu raug siv ejector pins.

Kev txhaj tshuaj molding tshuab ntau thiab tsawg tuaj yeem khiav txhua qhov chaw ntawm 5 tons ntawm clamping quab yuam rau ntau tshaj 6000. Qhov siab dua tonnage, lub tshuab loj dua. Qhov tseeb, txhaj tshuaj molding tshuab yog cais raws tonnage, lossis ntau dua qhov tseeb clamping quab yuam lossis siab.

Piv txwv li, lub tshuab uas muaj peev xwm xa tawm 110 tons ntawm clamping siab ntsuas rau 110 tons. Qhov siab no ua kom ntseeg tau tias pwm tseem kaw thaum lub sijhawm txheej txheem txhaj. Tshaj dhau lossis dhau heev dhau ntawm lub siab tuaj yeem ua rau cov teeb meem tsis zoo nrog rau kev nrawm, qhov chaw uas cov khoom siv ntau dhau ntawm ntug ntawm ib feem. Lub viscosity ntawm cov yas siv yog tseem cuam tshuam los ntawm lub siab. MFI lossis Melt Flow Index yog qhov ntsuas ntawm qhov yaj ntawm lub thermoplastic polymers yooj yim ntawm ntws.

Qhov ntau dua MFI, ntau dua qhov yuav tsum tau tonnage. Piv txwv li, cia peb hais tias koj muaj 4 kab noj hniav pwm thiab txhua ntu yog 5 "x 5" x 0.2 "square. Ua ntej, koj yuav tsum xam qhov cheeb tsam ntawm qhov ntu. Nrog cov pwm no, qhov kev txiav txim yuav yog 5 "x 5" = 25 square ntiv x 4 kab noj hniav = 100 square ntiv thaj tsam ntawm qhov chaw npaj. Kev xav cheeb tsam hauv cheeb tsam xav tau vim tias nws yog tus thawj xib fwb sib txawv uas cuam tshuam clamp tonnage. Yog tias peb siv 10 MFI Polypropylene, feem ntau peb yuav siv tsawg kawg yog 2.5 tons ib square nti ntawm qhov projected. Yog li rau qhov pwm no, 100 qhov rooj square hauv cheeb tsam qhov xav kom lub tshuab txhaj tshuaj yuav tsum muaj tsawg kawg yog 250 tons.

Lwm qhov hauv kev ntsuas lub tshuab kom raug yog tua loj thiab pwm qhov ntev.

Chav clamping chav ua haujlwm tseem ceeb yog kaw thiab qhib lub pwm ntxiv thiab txhaws qhov seem. Ob ntawm ntau hom kev tshaj plaws clamps yog cov toggle clamps thiab cov clamps hydraulic. Toggle clamps yog traversed los ntawm hydraulic kheej kheej. Cov clamps no siv cov khoom siv sib txuas los ua kom muaj zog ntau dua li cov hydraulic lub tog raj kheej ntawm tib qho loj uas siv cov khoom sib txuas ncaj qha.

Muaj ntau ntau ntxiv cov hauv paus thiab txheej txheem rau kev tshawb fawb thiab thev naus laus zis ntawm kev txhaj tshuaj molding uas peb tuaj yeem nkag mus rau hauv txoj haujlwm tom qab blog. Txawm li cas los xij, nws tsim nyog hais tias thaum lub hauv paus ntawm kev txhaj tshuaj moulding nyob rau qee qhov tsis tu ncua, ntau lub thev naus laus zis peb qhia rau hauv cov txheej txheem clamp uas muaj tam sim no thiab cov kev txhaj tshuaj ua rau ntau qhov kev txiav txim siab dhau los ua thaum tsim pwm lossis kev tsim lub tshuab rau kev txhaj tshuaj molding.
