Acrylic Thermoforming Kev Qhia
Kav kev nyiam huv tau yog ib qho ntawm cov khoom uas cais cov khoom zoo los ntawm seem. Tag nrho cov thermoforming cheeb tsam tau nyob zoo huv txhua lub sijhawm. Txawm tias ib qho plua plav me me los yog lint hauv huab cua yuav tshwm sim ua qhov tsis xws luag ntawm cov chaw tiav.
Dab tsi thermoforming ua tau yog
Qhov kev kub txhais tau tias cua sov daim yas ntim khoom kom txog thaum nws txhuam cov pwm, ces txhuam nws lossis rau hauv lub tshuab nqus tsev, siab, lossis siv tshuab lossis kho tshuab. Nws tuaj yeem yog ib yam dab tsi los ntawm ib tug txiv neej ua nws los ntawm txhais tes hauv lub khw me me mus rau txoj kab ib nrab ntawm ntau txhiab ib hnub.
Vim li cas tib neeg tseem xaiv thermoforming
Piv rau kev txhaj tshuaj molding los yog tshuab moulding, thermoforming muaj qee qhov zoo heev:
- Txoj kev ntsuas ntsuas yog qhov tsis zoo - feem ntau tsuas yog ob peb psi.
- Koj tuaj yeem ua qhov chaw loj heev yam tsis siv lub hmoov zoo.
- Tus pwm pom yuav luag tsis muaj kev quab yuam, yog li koj tuaj yeem ua nws tawm ntawm cov khoom siv pheej yig - ntoo, ncab, cob, cob, ua haujlwm.
- Cov cuab yeej ua lag luam ua lub sijhawm ntsuas tau raug ntsuas hauv cov hnub lossis lub lim tiam, tsis yog hli. Yog li ntawv yuav luag txhua qhov qauv, pauv kev lag luam, kev ua lag luam}}} Qhia cov qauv, lossis luv- khiav feem yog thermoformed.
Ntawm chav kawm, ib zaug koj tau txais yav dhau los ntxhib 10-20k daim, txhaj tshuaj feem ntau yeej rau ntawm daim {2} tus nqi - paub qab hau. Ntawm no yog ib tug tiag - Lub ntiaj teb tus nqi sib piv ib lub khw muab rau kuv ib qho nruab nrab- complexity:
| Kev ua | Tooling nqi | 500 pcs | 5,000 pcs | 10,000 pcs | 20,000 pcs |
|---|---|---|---|---|---|
| Siab Taus | ~$5,000 | $16.66 | $6.95 | $6.40 | $6.10 |
| Txhaj Tshuaj Molding | ~$37,500 | $78.07 | $10.37 | $6.53 | $4.65 |
Koj tuaj yeem pom qhov chaw hla kev tshwm sim.
Cov khoom sib txawv uas yeej muaj teeb meem
Nrum acrylic muaj hnyav heev molecular hnyav - nws sib ntaus koj thaum koj sim ncab nws, tab sis nws tuav kom sov zoo thiab tsis sag ntau hauv qhov cub.
Extruded Acrylic muaj qis dua molecular hnyav - nws ntws zoo nkauj, muab chais -} Kuv rhiab heev rau cov cua sov tsis sib xws. Yog tias ib sab tau kub dua li lwm tus, koj yuav pom nws tam sim ntawd hauv qhov tiav.
Tej yam koj yuav tsum xav txog thaum tsim qauv ib feem
Koj tsuas yog tau txais kev nthuav dav zoo ntawm cov pwm - Hu rau sab. Sab tod yog ib txwm yog "pub dawb" nto.
Acrylic txav ntau nrog kub, yog li muaj kev ua kom nruj dua li ± 0.020 "xav tau qhia" ntawm 70℃koj txhais tau tias.
Tso tsawg kawg 5 Degree Draft zaws txhua qhov chaw - ntau dua yog zoo dua.
Ntse fab yog tus yeeb ncuab. Txhua lub ces kaum yuav tsum muaj lub vojvoog. Qhov loj dua lub vojvoog, qhov ntau dua txawm tias lub phab ntsa tuab thiab qis dua lub puab tsaig- hauv kev ntxhov siab.
Kev sib sib zog nqus rub tau ntau -} theem kev sib sau (ntsaws, billow, snap - rov qab, thiab lwm yam). Cov khoom ntiav yuav ua tau nrog lub tshuab nqus tsev yooj yim lossis siab.
Phab ntsa thickness tas li thins tawm raws li koj kos ntxaum. Yog tias koj tsis ua ntej {{1 ncab} ncab daim ntawv, lub caij tsheb tuaj yeem xaus cov ntawv - nws yuag thaum lub npoo ruaj khov.
Mould Tsim Kev Sau Ntawv Los Ntawm Cov Xyoo Ua Qhov No
Pwm cov ntaub ntawv peb yeej siv:
Prototypes → Ntoo, MDF, RebRboard, Edboard, Epoxy Tuam Txhab Tuam Txhab
Ntau lawm → cam khwb cia ua txhuas rau 1,000-10,000 pcs, machined pcs, machined lossis dej {} txias aluminium / steel rau ntev khiav.
Deg tas: du yog qhov zoo, daim iav yog tsis zoo (ntxiab cua). Feem ntau ntawm peb siv lub teeb hlaws - tawg lossis zoo heev edm kev ntxhib los mos. Yog tias cov neeg siv khoom xav tau tawv lossis plaub hau, peb tsuas yog etch nws rau hauv pwm.
Lub Tshuab Nqus Tsev - Tib txoj cai txhua tus neeg tsis nco qab:
- Tsis txhob loj dua cov ntawv tuab
- Ib txwm rov qab - tho nrog ¼-⅜ "me ntsis txog li 0.090" los ntawm saum npoo
- Ob peb lub qhov → cov tawv nqaij uas tawv nqaij lossis tsis tiav
- Ntau dhau los yog loj heev → me ntsis dimples koj tsis tuaj yeem txhuam
Puab ntsuas kub - cia nws nyob ib ncig ntawm 190℃f (88 degree). Txias pwm=chill cim thiab kev ntxhov siab vwm. Kub pwm =}} koj tos ib sab rau qhov txias.
Cov txiv neej vs poj niam pwm - Nco ntsoov:
Tus txiv neej pwm → tuab cov khoom hauv qab, nyias ntawm ntug
Poj niam pwm → tuab tuab ntawm ntug, thinnest hauv qab
Xaiv raws li qhov uas koj xav tau cov khoom siv.
Lub Tshuab Nqus Tsev & Siab Lub Tshuab (cov khoom uas feem ntau tau skimped ntawm)
Koj yeej xav tau 28-30 ing ntawm pwm ntsej muag. Txhua 90 tus ntsuas lub luj tshib koj tuaj yeem rho tawm yog tsim nyog tiag tiag hauv lub sijhawm voj voog.
Siab sab: 99% ntawm ntu yog ua tiav ntawm 20-50 psi. Tsuas yog tus tiag tiag sib sib zog nqus lossis ntse -} Cov haujlwm nthuav dav mus rau 100-150 psi. Huab cua tau ua pob txha - qhuav thiab roj {9 {pub dawb.
Ua ntej -} qhuav
Extruded ntawv yuav luag tsis xav tau. Yog tias nws tau zaum hauv lub tsev khaws khoom noo rau lub hlis, muab pov rau hauv qhov cub ntawm 176℃f rau ib hnub. Cov Ntawv Cast - Yeej tsis qhuav nws.
Clamping
Clamps txias yog lub # 1 ua rau ntawm webbing thiab tsis muaj -}}, kos ntawm cov npoo. Sov ntawm clamp thav ntawv. Tiag.
Kev tsim cov kev ntsuas kub ua peb tau siv:
| Khoom | Txoj Kev Ua Ntau | Kev Nyab Xeeb Tshem Tawm | Lub Cim Pwm |
|---|---|---|---|
| Extruded Acrylic | 290-320 Degree F | 185 Qib F | ~ 190℃f |
| Nrab acrylic | 340-380℃f | 185 Qib F | ~ 190℃f |
Cua sov - tseem yog cov kauj ruam tseem ceeb tshaj plaws
Nyias ntawv (< 4 mm) → double-sided quartz infrared, fast and beautiful.
Cov ntawv tuab lossis qhov chaw kho qhov muag → forced - cua convection cub, lub sijhawm. Yog tias koj sim ua rau infrared - kub 6 hli nraus koj yuav ci ntsa iab ntev ua ntej cov tub ntxhais muaj kub txaus.
Cov Cua Sov Cua Sov Nrog Zoo Ob Chav Qhartz ntawm ~ 1200 Qib F Rhaub Kub:
| Qhov tuab | Lub sijhawm (ob sab tsoo) |
|---|---|
| 3 hli | 90-120 sec |
| 6 hli | 4-5 min |
| 9-10 hli | 8-11 Min |
| 12 hli | 12-16 min |
Txoj kev sib sau peb tau siv txhua hnub
Cov chaw ntiav → Ncaj lub tshuab nqus tsev los yog kev ntsuas siab
Nruab nrab kos → Plug - pab kub
Tob kos → Cillow + Plug lossis Snap {{1} rov qab + ntsaws (zoo tshaj thickness faib nyiaj tuaj yeem yuav)
Qhov chaw kho qhov muag → Free - tshuab lossis nqus {{sag mus rau ib lub nplhaib - tsis muaj cuab tam rau txhua qhov.
Cua txias
Tsis txhob maj nws. Txias ob sab tusyees kom txog thaum ib feem mus rau tsawg kawg ntawm 150℃f ua ntej koj rub nws tawm ntawm cov pwm. Pov tus tuab muaj kev pam vov hla cov tuab tuab li ib sab tsis txias sai dua thiab xauv hauv kev ntxhov siab.
Shrinkage - nws yuav tshwm sim
Extruded shrinks li 3% hauv tshuab kev taw qhia, yeej loj hlob ~ 0.5% hla.
Cov Sheet Shutins shrinks txog 1.5-2% ob txoj kev.
Nco ntsoov khiav ib qho kev sim ua ntej thiab ntsuas kub, tom qab ntawd kho koj qhov loj me.
Tom qab sib sau
Luas txawm koj nyiam - tuag txiav nyob rau hauv - kab yog tias koj tuaj yeem them taus nws, 5-axis cnc lossis router rooj yog tias koj ua tsis tau.
AnealE txhua yam uas yuav pom tau pom, dej cawv, lossis sab nraum zoov f rau kwv yees li 1 teev tsis nrawm dua li 25℃f / teev. Nws yog qhov sib txawv ntawm ib feem uas kav ntev li 6 lub hlis thiab ib qho uas kav 15 xyoos.
