Kev ntim cov hlwv ib txwm cia siab rau cov thermoforming: PVC, PET lossis PP nplooj ntawv yog rhuab kom muag muag ua ntej lub tshuab nqus tsev molding. Nyob rau hauv sib piv, txias forming aluminium composite foil (OPA/AL/PVC peb- txheej alu-alu base foil) ua tiav cov kab noj hniav sib sib zog nqus molding ntawm chav tsev kub yam tsis muaj cua sov ua ntej- kho. Kab lus no rhuav tshem nws cov khoom siv tshuab, tshuab ua haujlwm thiab cov txiaj ntsig tseem ceeb ntawm cov tshuab txias txias.
Core Precondition: Tshwj xeeb Composite Structure Enables Room -Tsuas Formability
Cov txheej txheem txias tuaj yeem hla cua sov tag nrho vim tias ntau- txheej txheej cov ntawv ci yog tsim los rau kev ua haujlwm txias txias, txhua txheej ua haujlwm ywj pheej ua haujlwm:
Sab nrauv Nylon (OPA) txheej - tensile buffer txheejOPA nylon nta zoo heev elongation thiab hnav tsis kam. Thaum lub sij hawm stamping, nws dais feem ntau nto tensile quab yuam los tiv thaiv nruab nrab nyias txheej ntawm txhuas los ntawm cracking los yog pinholing nyob rau hauv ntse pwm nro. Nylon lub siab ductility ua rau chav - qhov kub thiab txias stretching ua tau yam tsis muaj thermal softening.
Nruab nrab Aluminium ntawv ci txheej - txheej txheej txheej txheejLub substrate txais tag nrho annealed soft- xeev aluminium alloy (8021-O / 8079-O), nrog ultra-low hardness thiab superior yas deformation muaj peev xwm. Mos aluminium ntawv ci tuaj yeem tsim cov yas deformation mus tas li nyob rau hauv cov neeg kho tshuab siab siab ntawm qhov kub thiab txias, uas yog lub hauv paus ntawm kev ua kom txias txias. Nws cov yam ntxwv tuag-fold ua rau cov kab noj hniav tsim kom ruaj khov yam tsis muaj rov qab los.
Sab hauv PVC / PVDC cua sov- txheej txheej - hloov pauv hloov pauvMos PVC zaj duab xis muab nruab nrab yooj thiab adhesion, synchronously stretches nrog txhuas thiab nylon thaum sib sib zog nqus nqus. Nws tsis txhob nkig tawg ntawm chav tsev kub thiab tswj kom zoo lamination kev ncaj ncees tom qab tsim.
Kauj ruam-los ntawm-Chav Kauj Ruam-Tub Txias Txias Moulding Workflow
Tag nrho cov kab ntau lawm tshem tawm cua sov qhov cub, infrared preheating thiab kub cov menyuam chav. Tag nrho cov txheej txheem molding khiav hauv qhov chaw ua haujlwm kub ib txwm:
Foil Unwinding & Tension Control Composite txias daim ntawv foil yog unwound tsis tu ncua nrog kev nro hloov kho kom tshem tawm wrinkles; tsis muaj preheating yog siv rau cov ntawv ci web.
Mechanical Plug-Assist Cold Stamping (Core Forming Stage) Cov ntawv ci tiaj tiaj hla ntawm cov pwm sab sauv (poj niam kab noj hniav) thiab qis dua punch plug. Tsav los ntawm hydraulic los yog pneumatic siab, lub punch thawb cov ntawv ci rau hauv cov pwm kab noj hniav tam sim ntawd. Pure mechanical force stretches peb -txheej txheej sib xyaw kom sib sib zog nqus hlwv kab noj hniav. Cov ntsiab lus tseem ceeb: Tsis muaj qhov cua sov tiv thaiv cov ntawv ci thaum lub sij hawm stamping; tag nrho cov kev hloov pauv nyob ntawm lub cev extrusion thiab ncab.
Cavity Shaping & Material Yas Deformation Mos aluminium foil generates mus tas li deformation nyob rau hauv extrusion. OPA txheej txheej stretches los npog kab noj hniav ces kaum tsis rupture, puab PVC ua raws li cov contour synchronously. Thaum lub siab tso tawm, tuag-fold aluminium tuav peb - kab noj hniav tsis muaj springback.
Ncej -Txoj kev xa khoom & Cov txheej txheem tom ntej Cov ntawv xaim xaim ncaj qha mus rau sau, sib khi nrog PTP lidding ntawv ci, slitting thiab xuas nrig ntaus cov kauj ruam. Tsis muaj qhov chaw txias txias yuav tsum tau vim tias cov ntawv ci kub tsis hloov pauv thoob plaws hauv kev tsim.
Vim li cas Thermoforming xav tau cua sov thaum txias tsim tsis?
| Thermoforming PVC / PET Sheet | Daim ntawv txias OPA / AL / PVC Composite Foil |
|---|---|
| Cov ntawv yas yog nruj ntawm chav tsev kub, nkig thaum ncab; yuav tsum tau rhuab saum iav hloov kub kom tau ductility | Composite ntawv ci nrog mos annealed aluminium + siab -elongation nylon, ntuj chav- kub ductility, tsis xav tau cua sov |
| Kev sib sau cia siab rau lub tshuab nqus tsev tom qab thermal softening; qhov tob tob xwb | Txoj kev vam khom rau txhua yam ntsaws stamping; sib sib zog nqus daim duab muaj nyob rau ntawm ambient kub |
| Tsis muaj hlau txheej, tsis muaj zog barrier kev ua tau zoo | Nruam txhuas txheej ua tiav tag nrho lub teeb, oxygen thiab noo noo barrier |
Tshwj xeeb zoo ntawm cua sov-Free Cold Forming Mechanism
Kev siv hluav taws xob qis Tshem tawm qhov cub cua sov siv hluav taws xob; txiav tag nrho cov nqi hluav taws xob los ntawm 30% -50% piv nrog cov kab thermoforming.
Stable Drug Packaging Material Performance Tsis muaj siab - kub raug thaum lub sij hawm tsim, tsis txhob thermal aging ntawm composite ntawv ci thiab tiv thaiv thermal degradation ntawm tshav kub- rhiab cov ntawv luam tawm ntawm cov ntawv ci.
Lub Hwj Chim Loj Tshaj Plaws Zoo Tshaj Plaws-Qhov kub ntawm cov yas deformation ntawm cov mos aluminium paub qhov tob tob rau cov tshuaj ntsiav loj, cov ntsiav tshuaj oval thiab siab - cov tshuaj noj uas tsis tuaj yeem tsim los ntawm thermoforming li niaj zaus.
Simplified Production Line Structure Tshem cov cua sov, txias thiab kub tswj modules; txo cov cuab yeej tsis ua hauj lwm tus nqi thiab txo cov kev tu txhua hnub.
Kev cia dav dav & Ntau qhov kub thiab txias Adaptability Moulding nyhuv yog tsis cuam tshuam los ntawm me me rhiav kub hloov pauv; ruaj khov tsim zoo nyob rau hauv lub caij ntuj no txias los yog siab - kub kub factories.

Cov cua sov-dawb txias tsim ntawm aluminium composite foil yog pom los ntawm kev sib tw ductility ntawm nylon thiab mos annealed aluminium alloy hauv peb- txheej txheej. Es tsis txhob thermal softening, nws siv cov neeg kho tshuab ntshiab extrusion thiab ncab kom ua tiav qhov chaw ruaj khov ntawm chav tsev kub. Lub hauv paus ntsiab lus tsim tau qhov txawv ntawm alu-alu hlwv pob los ntawm cov hnab yas zoo tib yam thermoformed hlwv, xa cov kab mob siab sib sib zog nqus -kab noj mov ntim nrog qis zog noj thiab cov khoom siv ruaj khov rau kev lag luam tshuaj thiab nutraceutical.
