Cov ntaub ntawv dab tsi yog siv hauv 2K Txhaj Moulding?

2K molding (los yog ob -xim molding), raws li kev ua tau zoo, meej, thiab cov txheej txheem tsim khoom muaj peev xwm ua tiav cov haujlwm nyuaj thiab cov txiaj ntsig zoo nkauj, tso siab rau kev tshawb fawb sib txuam ntawm ob cov ntaub ntawv polymer. Kev xaiv cov khoom siv tsis tsuas yog txiav txim siab lub cev lub cev, qhov pom, thiab lub neej ntev ntawm cov khoom kawg, tab sis tseem cuam tshuam ncaj qha rau qhov ua tau thiab cov txiaj ntsig ntawm cov txheej txheem molding. Kab lus no yuav piav qhia txog cov hauv paus ntsiab lus ntawm kev xaiv cov khoom siv, kev sib xyaw ua ke, thiab kev txiav-txoj kev sib txawv hauv ob- kev txhaj tshuaj molding los ntawm kev xav ntawm cov ntaub ntawv tshawb fawb, txheej txheem txheej txheem, thiab kev siv engineering.

 

I. Cov Ntsiab Cai Kev Tshawb Fawb Txog Kev Xaiv Cov Khoom Siv:

Hauv ob- txhaj tshuaj molding, kev sib txuas ntawm ob cov ntaub ntawv tsis yog kev sib cuag ntawm lub cev; nws lub zog feem ntau yog nyob ntawm ob lub tshuab hauv qab no. Nkag siab txog cov txheej txheem no yog qhov tseem ceeb rau kev xaiv cov khoom siv:

Chemical / Thermodynamic Bonding: Thaum ob cov ntaub ntawv tuaj rau hauv kev sib cuag hauv lub xeev molten, yog tias lawv cov saw hlau molecular muaj kev sib raug zoo txaus, kev sib nrig sib txawv thiab kev sib txuas tuaj yeem tshwm sim ntawm qhov sib cuam tshuam, tsim cov tshuaj lom neeg muaj zog lossis muaj zog van der Waals rog. Qhov no yuav tsum muaj ob yam khoom kom muaj:

 

1.Similar polarity: Cov khoom siv nrog cov polarity zoo sib xws (xws li ABS thiab PMMA) tau yooj yim dua.

• Zoo sib xws solubility parameters (SP tus nqi):Qhov ze dua qhov SP qhov tseem ceeb, qhov ntau thermodynamically haum rau kev sib nrig sib tawg thiab diffusion.
• Matching processing kub qhov rais:Qhov kub ntawm cov khoom siv txhaj tshuaj thib ob yuav tsum txaus kom me ntsis remelt nto ntawm cov khoom siv txhaj tshuaj thawj zaug, tab sis tsis ua rau thermal degradation los yog deformation loj.

 

2.Mechanical Interlocking:Thaum ob cov khoom siv tshuaj tsis sib haum, kev tsim pwm tsim nyog tsim nyog los tsim cov qauv ntawm lub cev xws li undercuts, qhov, thiab grooves ntawm thawj qhov txhaj tshuaj. Cov khoom siv txhaj tshuaj thib ob molten puv thiab nyob ib puag ncig cov qauv no, ua rau lub tshuab xauv tom qab txias. Txoj kev no yuav tsum tsis muaj kev sib raug zoo ntawm cov ntaub ntawv lawv tus kheej, tab sis tus qauv tsim yog complex, thiab lub zog sib txuas feem ntau yog qis dua li cov tshuaj sib txuas zoo heev.

 

II. Classic Material Combination Systems thiab lawv daim ntawv thov teb

Raws li cov hauv paus ntsiab lus tau piav qhia saum toj no, kev lag luam tau tsim ntau yam khoom pov thawj classic ua ke, uas tuaj yeem muab faib ua cov hauv qab no:

 

(I) Cov yas tawv thiab mos yas Composite System (Overmolding)

Cov txheej txheem no yog qhov ntau tshaj plaws, txhawm rau muab cov khoom lag luam zoo siab, tuav zoo heev, kev poob siab thiab kev sib khi ua haujlwm, thiab muaj txiaj ntsig zoo - zoo li.

 

Base Khoom (Hard Plastic):

• ABS: Kev ua tau zoo tag nrho, kev ua haujlwm yooj yim, thiab kev nyiam dav dav - lub hom phiaj xaiv.
• PC/ABS alloy: Ua ke lub zog thiab kub tsis kam ntawm PC nrog lub toughness thiab processability ntawm ABS, dav siv nyob rau hauv automotive interiors thiab siab -kawg hluav taws xob khoom.
• PA (Nylon): tshwj xeeb tshaj yog iav fiber reinforced PA, muab siab rigidity, tshav kub tsis kam, thiab tshuaj tsis kam, siv nyob rau hauv cov khoom ua si thiab muaj cov khoom.
• PP: Low density, low cost, and fatigue resistance, often used in automotive parts and daily consumer goods.

 

Soft Yas Overmolding Khoom:

• Thermoplastic Elastomer (TPE / TPR): Muaj ntau hom muaj, thiab cov qauv tuaj yeem hloov kho raws li qhov nyuaj, xav, thiab huab cua tsis kam. Nws muaj qhov zoo adhesion rau polar plastics (xws li ABS thiab PC) thiab yog tus nqi ntau tshaj - kev xaiv zoo.
• Thermoplastic Polyurethane Elastomer (TPU): Muaj kev hnav zoo heev, elasticity siab, tsim kua muag, thiab roj tsis kam. Nws muaj qhov ua tau zoo rau PC thiab ABS thiab feem ntau siv rau hauv siab - cov cuab yeej kawg, cov khoom siv ntse ntse, thiab cov khawm tsheb.
• Liquid Silicone Roj Hmab (LSR): Yuav tsum muaj ob - xim txhaj tshuaj molding tshuab. Nws muaj biocompatibility zoo heev, siab thiab kub tsis kam (-60℃rau 250 degree), mos kov, thiab tshuaj inertness, ua rau nws yog ib qho kev xaiv saum toj kawg nkaus rau kev kho mob, menyuam mos, khoom noj khoom haus sib cuag, thiab sealing daim ntaub ntawv.

 

(II) Cov Khoom Siv Hluav Taws Xob thiab Cov Khoom Siv Hluav Taws Xob
Feem ntau yog siv los ua kom tiav ob -xim zoo nkauj, kev ua haujlwm zoning, lossis kev txhawb nqa hauv zos.

Cov khoom siv tib yam, Cov xim sib txawv / yam ntxwv: xws li ABS / ABS, PC / PC, ua tiav kev ua haujlwm zoning los ntawm kev ntxiv cov xim lossis cov hloov pauv (xws li iav fiber ntau, nplaim hluav taws xob). Cov txheej txheem no yog qhov ruaj khov tshaj plaws.

 

Heterogeneous High -Compatibility Combinations:

• PC + ABS:Kev sib xyaw golden. Cov kev tsis sib haum xeeb ntawm ob yog nyob ze, thiab cov txheej txheem alloy tuaj yeem tsim los ntawm kev sib cuam tshuam molten los ntawm kev sib nrig sib txawv, uas ua rau muaj kev sib koom siab siab. Dav siv nyob rau hauv lub Cheebtsam uas yuav tsum tau muaj zog structural thiab complex tsos.
• PA + Modified PPO:Siv nyob rau hauv automotive engine peripheral Cheebtsam yuav tsum tau kub kub tsis kam thiab siab seem stability.

 

(III) Cov Txheej Txheem Tsis Txaus Siab Raws li Mechanical Interlocking

Thaum cov khoom siv tshuaj lom neeg sib txawv loj heev (xws li crystallinity thiab tsis yog -crystallinity, polarity thiab non-polarity), tsim qauv yog qhov tseem ceeb.

 

Kev sib xyaw ua ke:PP + PA, POM + TPE, ABS + PP. Feem ntau pom muaj nyob rau hauv cov khoom uas xav tau cov haujlwm tshwj xeeb hauv zos (xws li lub pob khawm ntawm PP, tus kheej -lubricating zog ntawm POM) ua ke nrog cov qauv tseem ceeb.

 

III. Cov txheej txheem kev txiav txim siab txog cov khoom siv thiab cov txheej txheem tseem ceeb

Kev xaiv cov khoom yuav tsum ua raws li txheej txheem kev ntsuam xyuas engineering:

Kev Ntsuam Xyuas Kev Ua Haujlwm thiab Kev Tswj Xyuas Cov Cai: Kom meej meej cov khoom kawg - siv ib puag ncig (cov khoom siv thauj khoom, qhov kub thiab txias, tshuaj tiv thaiv), cov qauv kev nyab xeeb ( nplaim taws retardancy UL94, zaub mov tiv tauj FDA), thiab cov kev xav tau xws li kev xav thiab kev pom.

 

Kev ntsuam xyuas ua ntej Compatibility:

• Nrog rau ob -xim txhaj tshuaj molding compatibility matrix muab los ntawm cov khoom siv.
• Paub meej tias qhov kub ntawm qhov melting (Tm) los yog iav hloov kub (Tg) ntawm ob cov ntaub ntawv sib tw los ntawm thermal tsom xam (DSC, TGA). Qhov zoo tshaj plaws, kev ua haujlwm kub ntawm cov khoom siv txhaj tshuaj thib ob yuav tsum siab dua li Tg ntawm cov khoom siv txhaj tshuaj thawj zaug (rau amorphous plastics) lossis qis dua nws Tm (rau crystalline plastics) kom ua tiav qhov micro- melting yam tsis muaj deformation.

 

Cov txheej txheem tseem ceeb Parameter Matching Kev Ntsuam Xyuas:

• Shrinkage tus nqi:Lub linear shrinkage tus nqi ntawm ob cov ntaub ntawv yuav tsum nyob ze li sai tau, tshwj xeeb tshaj yog qhov sib txawv ntawm shrinkage tus nqi ntawm cov kev taw qhia ntws thiab perpendicular kev taw qhia. Kev tsis sib haum xeeb hnyav yuav ua rau muaj kev sib cav sib ceg, kev ntxhov siab ntau dhau ntawm sab hauv, thiab txawm tias kev sib tsoo. Piv txwv li, tus nqi shrinkage ntawm PA yog ntau dua li ntawm ABS, ua rau kev sib txuas ncaj qha tsis tshua muaj kev pheej hmoo.
• Melt Viscosity:Ntawm qhov kev cia siab ua haujlwm kub, lub melt flow index (MFI) ntawm ob cov ntaub ntawv yuav tsum nyob rau hauv ib tug ntau yam uas tso cai rau kev sib koom ua ke los xyuas kom meej tias qhov thib ob txhaj koob tshuaj tivthaiv yuav smoothly sau thiab encapsulate thawj txhaj tshuaj tivthaiv.

 

Kev kuaj xyuas:

• Ua qhov chaw sim- ntsuas qhov sib piv(xws li, kuaj lub tev lub zog tom qab kub- nias nyias nyias ntawm ob cov ntaub ntawv).
• Ua ib qho pwm pwm rau kev sim molding.Qhov no yog txoj kev txheeb xyuas qhov tseeb tshaj plaws, tso cai rau kev soj ntsuam ncaj qha ntawm daim ntawv cog lus lub zog, qhov tsis xws luag, thiab cov txheej txheem ruaj khov.
