Cov txheej txheem thermoforming muaj cov kauj ruam hauv qab no:
1. Ua kom sov cov ntawv rau qhov kub thiab txias
2. Ua ntej- ua daim ntawv rhuab los ntawm preheating thiab ncab
3. Nqus cov khoom los tsim cov khoom
4. Txias cov khoom
5. Demolding cov khoom
Pwm txoj kev yog muab faib ua txiv neej thiab poj niam pwm
I. Qhov txawv ntawm Poj Niam thiab Txiv Neej Pwm
1. Qauv
Poj niam pwm (concave pwm): Cov pwm saum npoo yog concave sab hauv. Thaum lub tshuab nqus tsev tsim cov txheej txheem, cov khoom siv npog sab nraud ntawm pwm, tsim cov khoom.
Txiv neej pwm (convex pwm): Cov pwm saum npoo yog convex sab nraud. Thaum lub tshuab nqus tsev tsim cov txheej txheem, cov khoom siv npog sab hauv pwm, tsim cov khoom.
2. Yam khoom tshwm sim
Poj niam pwm: Sab nrauv ntawm cov khoom yog du (sab sab raug rau huab cua), thiab sab hauv tuaj yeem ntxhib (sab uas hu rau pwm).
Txiv neej pwm: Sab hauv ntawm cov khoom yog du (sab uas hu rau pwm), thiab sab nrauv yuav ntxhib (sab uas hu rau pwm).
3. Demolding yooj yim
Poj niam pwm: Demolding yog yooj yim dua vim hais tias cov yas ib txwm khiav tawm ntawm kab noj hniav thaum nws txias thiab shrinks. Txiv neej pwm: Demolding yog qhov nyuaj dua, tshwj xeeb tshaj yog rau cov khoom sib sib zog nqus -kab noj hniav. Draft cov ces kaum, lub qhov cua, los yog ejector mechanisms yuav tsum tau.
4. Cov khoom siv Thickness
Poj niam pwm: Haum rau cov ntaub ntawv thinner (piv txwv li, 0.2-1.0 mm) vim tias lawv nthuav tawm tsawg dua.
Txiv neej pwm: Haum rau cov ntaub ntawv tuab (piv txwv li, tshaj 1.0 hli) vim tias lawv xav tau kev ncab ntau dua.
5. Cov ntawv thov ib txwm
Poj niam pwm: Cov khoom uas yuav tsum tau muaj lub ntsej muag zoo nkauj, xws li cov tais zaub mov, ntim khoom kom zoo nkauj, thiab cov khoom siv hluav taws xob.
Txiv neej pwm: Cov khoom lag luam xav tau cov kab noj hniav sib sib zog nqus lossis cov phab ntsa sab hauv siab, xws li cov dab da dej, automotive interiors, thiab cov khoom lag luam loj.
II. Yuav Ua Li Cas Xaiv Tus Poj Niam lossis Txiv Neej Pwm?
1. Xaiv raws li cov khoom tshwm sim
Sab nrauv yuav tsum tau (xws li, luam ntawv, smoothness) → Poj niam pwm yog nyiam.
Sab hauv qhov yuav tsum tau muaj (xws li, qhov tseeb qhov tseeb, cov qauv sib dhos) → Txiv neej pwm yog nyiam.
2. Xaiv raws li cov khoom zoo
Plua plav, cov khoom tiaj tus (piv txwv li, cov tais, hau) → Poj niam pwm yog qhov tsim nyog, muab cov molding yooj yim dua thiab sai demolding. Sib sib zog nqus-cov khoom siv kab noj hniav (xws li cov thoob thiab cov thawv) → Ib tug txiv neej pwm yog tsim nyog, tab sis demolding teeb meem yuav tsum tau xav txog.
3. Kev xaiv raws li kev ua tau zoo
Loj -batch ntau lawm → Ib tug poj niam pwm yog qhov zoo tshaj plaws, muab kom txias dua thiab yooj yim demolding.
Me me -batch los yog complex lug → Ib tug txiv neej pwm nrog auxiliary demolding nta (xws li cua tshuab los yog ejector pins).
4. Kev xaiv raws li tus nqi
Pwm poj niam: Cov qauv yooj yim, cov nqi ua haujlwm qis, tsim nyog rau cov haujlwm uas muaj peev nyiaj tsawg.
Pwm zoo: Cov txheej txheem nyuaj yuav xav tau cov nqi pwm ntau dua, tab sis tuaj yeem ua kom cov phab ntsa sab hauv.
III. Piv txwv kev siv
1.Packing tray (xws li lub thawv khoom noj ceev) → Ib tug poj niam pwm: Ua kom lub ntsej muag du thiab cov txiaj ntsig zoo.
2.Automobile dashboard npog → Ib tug txiv neej pwm: Xyuas kom meej puab phab ntsa qhov ntev thiab haum rau ib feem.
3.Kev kho mob cov tais (nrog rau daim npav qhov) → Ib tug poj niam pwm nrog ib nrab ntawm cov txiv neej pwm qauv: Ntsuas qhov zoo thiab kev ua haujlwm.
Pwm poj niam: Tsim nyog rau cov haujlwm uas xav tau kev zoo nkauj siab, cov qauv ntiav, thiab loj - teev ntau lawm. Txiv neej pwm: Haum rau cov khoom uas muaj siab puab phab ntsa precision, sib sib zog nqus kab noj hniav qauv, thiab tshwj xeeb yuav tsum tau ua hauj lwm.
Cov khoom lag luam nyuaj: Cov txiv neej thiab poj niam pwm (cov pwm pwm) tuaj yeem ua ke, tab sis qhov no yog kim dua.
Kev xaiv cov pwm tsim nyog yuav tsum muaj kev txiav txim siab zoo ntawm cov khoom tsim, cov khoom siv, kev tsim khoom, thiab tus nqi. Vam tias, phau ntawv qhia no yuav pab koj txiav txim siab paub ntau ntxiv!
Kev sib piv ntawm cov khoom pwm zoo thiab tsis zoo
| Feature | Txiv neej pwm khoom | Poj niam cov khoom pwm |
| Moulding raug ntawm cov khoom | Nyob rau hauv | Nyob sab nraud |
| Dimensioning (thaum kos duab) | Nyob rau hauv | Nyob sab nraud |
| posterior margin cheeb tsam | Stretching ua rau thinning ntawm ntug | Cov npoo tsis tau stretched thiab cov phab ntsa thickness tseem zoo ib yam li thawj thickness |
| Thickest ib feem | Hauv qab | Nyob ntawm ntug |
| Thinest ib feem | Nyob rau ntawm ntug (hloov mus rau sidewall) | Hauv qab (hloov mus rau sab phab ntsa) |
| Kev phom sij ntawm quilt wrinkles | Ntawm lub ces kaum tsim los ntawm ntug | Tsis muaj pleats tsim |
Txias cov cim ntawm cov txiv neej ua qhov chaw. Ntawm cov txiv neej lub tiaj tus moulded qhov chaw, cov cim cua txias feem ntau tshwm sim nyob rau sab saum toj ntawm cov pwm. Thaum lub sij hawm loj stretching txheej txheem, cov cim txias yog rub mus rau sab phab ntsa thaum lub sij hawm molding txheej txheem. Cov cim txias ntawm cov poj niam molded qhov chaw. Tsis zoo li cov cim txias ntawm cov txiv neej molded qhov chaw, thaum lub sij hawm molding txheej txheem, cov ntaub ntawv cov ntaub ntawv tsis txuas ntxiv mus rau hauv lub sidewalls tom qab kev sib cuag nrog cov pwm ntawm ib tug tej yam taw tes, uas ua rau cov cua txias cim.
