AS

AS yog ib qho ntshiab lossis ib nrab -pob tshab rigid yas paub rau nws qhov siab gloss, zoo tshuaj tiv thaiv, thiab kev ua haujlwm ruaj khov. Nws yog lub teeb yuag, yooj yim rau pwm, thiab muaj qhov zoo nkauj, polished, ua rau nws xaiv zoo heev rau cov neeg siv khoom xws li cov khoom siv hauv lub tub yees, cov chaw taws teeb tswj lub plhaub, pob tshab npog, thiab ntau yam khoom zoo nkauj lossis cov khoom siv.

4.Optimal Moulding Parameters

1. Qhov zoo ntawmASTxhaj Molding

• High nto gloss thiab zoo heev tsos zoo, haum rau pob tshab los yog semi- pob tshab qhov chaw
• Cov tshuaj tiv thaiv zoo thiab qhov ruaj khov, haum rau txhua hnub - siv thiab cov khoom siv
• Lub teeb yuag, nruj, yooj yim rau pwm, thiab txhawb kev nthuav dav kom rov ua dua tshiab
• AS txhaj tshuaj molding yog dav siv nyob rau hauv cov neeg siv khoom electronics vaj tse, teeb pom kev zoo npog, tso saib cov khoom, thiab cov khoom zoo nkauj

Peb tau tsim AS molded Cheebtsam rau:

• Portable tub yees vaj tse
• Tej thaj chaw deb tswj shells
• Pob tshab tiv thaiv npog thiab tso saib lo ntsiab muag
• Ntau yam customized AS qhov chaw rau cov neeg siv khoom thiab cov ntawv thov kev lag luam

2. Daim ntawv thov teb ntawm AS Txhaj Molding

Qhia & Kos Npe: Pob tshab npog, cov vaj huam sib luag tso saib, lub teeb -Diffusing Cheebtsam

Teeb pom kev zoo: Lub teeb vaj tse, npog tiv thaiv, semi-pob tshab lo ntsiab muag

Consumer & Industrial Products: Cosmetic vaj tse, ntim, tiv thaiv vaj huam sib luag, cov khoom siv me me

Chaw Ua Haujlwm & Cov Khoom Siv Hauv Tsev: Cov khoom siv hauv tsev, cov tais, cov thawv ntim khoom, cov khoom siv zoo nkauj

3. Yuav ua li cas kom tau ib tug zoo nto tiav rau AS txhaj Moulded qhov chaw

Cov tsos ntawm AS qhov chaw nyob ntawm cov pwm zoo, tswj qhov kub thiab txias, thiab kev ua haujlwm ruaj khov. Txij li thaum AS yog rhiab heev rau shear thiab tsis kub heev- tiv taus, kev tswj xyuas meej thaum txhaj tshuaj molding yog qhov tseem ceeb los tswj cov gloss, tsis txhob ntws cov cim, thiab tiv thaiv qhov tsis xws luag.

3.1 Pwm Zoo

Cavity tiav: Nto teeb meem los yog roughness yuav txo gloss. Highly polished kab noj hniav yog pom zoo rau glossy tsos.

Kev huv huv: Cov plua plav lossis cov khoom paug tuaj yeem ua rau streaks, qhov chaw du, lossis cov pob dub; pwm tu yuav tsum nquag.

Draft lub kaum sab xis: Tsim kom tsim nyog tsis txhob rub cov cim thiab ua kom cov ejection du, tshwj xeeb tshaj yog rau siab -gloss.

Lub tshuab ua pa: qhov cua tsis zoo yuav ua rau muaj qhov kub hnyiab, cov kab ntws, lossis cov cua nkag; optimized vents txhim kho flow uniformity.

Lub rooj vag thiab khiav tsim: Kev hloov pauv tau zoo thiab lub rooj vag kom zoo txo ​​qis kev ntxhov siab, tiv thaiv kev ua kom dawb los yog ntws tsis xws luag.

3.2 Moulding Parameters

Kev txhaj tshuaj nrawm: Nruab nrab ceev tiv thaiv cov kab khiav thiab kev ntxhov siab ua kom dawb; ntau ceev tsub kom shear.

Lub tshuab ua kom txias: Cov cua txias ua kom zoo dua qhov kev ruaj ntseg thiab txo qhov kev sib tw rau qhov loj lossis tiaj tus.

Tuav siab & sijhawm: Cov chaw tsim nyog tiv thaiv cov cim dab dej thiab xyuas kom muaj qhov sib xws.

Melt kub: AS muaj qhov ua haujlwm nruab nrab; overheating tuaj yeem ua rau yellowing, hlawv cov cim, lossis txo qhov gloss.

3.3 Cov khoom siv raw

Granule uniformity: Raws li qhov loj me me pab tswj cov dej ntws sib xws thiab du nto tiav.

Cov ntsiab lus noo noo: AS tsis tshua muaj hygroscopic tab sis tseem yuav tsum tau qhuav kom tsis txhob muaj npuas thiab qhov tsis xws luag.

Additive thiab colorant dispersion: Tsis zoo dispersion ua rau streaks thiab xim tsis sib xws ntawm glossy nto.

impurities: Cov khoom paug ua rau cov pob dub, streaks, lossis cov ntsiab lus nkig; cov ntaub ntawv yuav tsum tau soj ntsuam.

Cov ntsiab lus rov ua dua: Kev rov ua dua qub tuaj yeem txo qhov gloss, txhua yam muaj zog, thiab xim tsis sib xws.

4.Best Parameters rau AS Txhaj Molding

4.1 Cov Khoom Tseem Ceeb

Thermal Sensitivity: AS cov txheej txheem ntawm kwv yees . 200-260℃; overheating yuav ua rau yellowing los yog degradation nto.

Flow Behavior: AS yog shear-sensitive; nruab nrab txhaj tshuaj ceev thiab siab kom du ntws thiab tiv thaiv kev nyuaj siab whitening.

Shrinkage Rate: 0.3-0.7% nyob ntawm cov qauv ib feem, muab kev ruaj ntseg zoo.

Tshuab Hom: Ntsia hlau- hom txhaj tshuaj tshuab nrog kev tswj qhov kub thiab txias tiv thaiv overheating thiab tswj qhov gloss.

Txhaj ntim: Qhov zoo tshaj plaws 50-70% ntawm lub tshuab muaj peev xwm txo qis lub sijhawm nyob thiab thermal stress.

Runner Design:

- Tus khiav tseem ceeb: Tsawg dua lossis sib npaug li 120 mm

- Sub- khiav: 5–10 mm

- Cov neeg ua haujlwm sib tw, sib tw ua kom qis qis thiab tswj xyuas qhov zoo.

Ejection Force: Lub zog nruab nrab pom zoo kom tsis txhob muaj kev ntxhov siab rau ntawm qhov chaw glossy.

Tom qab-Kev kho mob: AS feem ntau tsis tas yuav tsum tau muab tshem tawm, tab sis kev txias me ntsis tuaj yeem pab txo qis kev ntxhov siab sab hauv rau cov khoom tuab.

4.2 Yam Moulding Parameters

Cov molding parameters rau AS qhov chaw txawv nyob ntawm seb cov qib (general-lub hom phiaj, siab-flow, los yog xim), ib feem thickness, thiab yuav tsum tau deg tag. Txij li AS yog shear-rhiab heev thiab tsis kub hnyiab heev- tiv taus, kev tswj qhov kub thiab txias, kev txhaj tshuaj me me, thiab kev ua kom txias txias yog qhov tseem ceeb kom tsis txhob yellowing, ntws cov cim, kev ntxhov siab ua kom tawv nqaij, lossis qhov tsis xws luag.

Cov kev ntsuas no ua raws li cov lus qhia dav dav. Zoo- yuav tsum tau kho raws li ib feem geometry, phab ntsa thickness, colorant concentration, runner design, thiab txias layout kom ua tau zoo nto gloss, seem stability, thiab xim uniformity.
