Part 1: Tshuaj Anatomy – Yas Ua Dab Tsi?
Yuav kom nkag siab txog ib feem yas, koj yuav tsum xub nkag siab nws cov molecular thiab tshuaj pleev ib ce. Plastics yog hluavtaws lossis semi-synthetic organic polymers. Cov khoom siv yas tiav tsis tshua muaj ib yam khoom ntshiab; nws yog ib daim ntawv qhia ua tib zoo tsim los ntawm ntau lub ntsiab lus tseem ceeb.
1. Lub hauv paus Polymer (Resin)
Lub hauv paus ntawm txhua qhov yas yog cov polymer resin. Polymers muaj qhov ntev, rov ua cov saw hlau ntawm cov molecules hu ua monomers. Cov resins no tau muab faib ua ob pawg thawj:
Thermoplastics:Cov ntaub ntawv no yaj thaum rhuab thiab solidify thaum txias, cia lawv remolded ntau zaus. Piv txwv xws li Polyethylene (PE), Polypropylene (PP), Acrylonitrile Butadiene Styrene (ABS), Polycarbonate (PC), thiab Nylon (PA).
Thermosetting Plastics:Cov no tau txais kev hloov tshuaj thaum kho (feem ntau ntawm tshav kub lossis UV teeb) thiab tsis tuaj yeem rov ua dua. Thaum zoo li tus, lawv cov tshuaj tiv thaiv kab mob tau hla mus tas li - txuas.
NtawmSWKS, peb ua haujlwm nrog lub tsev qiv ntawv loj ntawm ob qho tib si engineering plastics thiab qib siab elastomers / roj hmab kom ntseeg tau tias koj qhov kev cai sib tw rau koj qhov chaw ib puag ncig.
2. Cov khoom siv ntxiv thiab hloov kho
Txhawm rau muab lub hauv paus polymer cov khoom siv lub cev xav tau, cov tuam ntxhab qhia ntau yam ntxiv thaum lub sijhawm sib xyaw:
Plasticizers:Ntxiv rau kev ua kom yooj yim thiab ua haujlwm tau zoo (nrog rau PVC).
Stabilizers:UV stabilizers thiab thermal stabilizers tiv thaiv cov yas los ntawm degrading, yellowing, los yog ua nkig thaum raug tshav ntuj lossis kub ua haujlwm siab.
Colorants:Pigments lossis dyes uas muab cov yas nws cov xim tshwj xeeb.
Nplaim Retardants:Cov tshuaj uas inhibit lossis ncua kev sib kis ntawm hluav taws, tseem ceeb heev rau cov khoom siv hluav taws xob thiab tsheb.
3. Kev txhawb zog thiab cov khoom ntim
Rau cov qauv lossis kev thauj khoom- cov ntawv siv kabmob, cov yas ntshiab feem ntau tsis muaj lub zog tensile txaus. Yog li ntawd, fillers tau ntxiv:
Cov iav Fibers (GF):Ua kom muaj zog tensile thiab rigidity (piv txwv li, PA66-GF30).
Carbon Fibers:Siv rau lub teeb yuag, ultra- siab - lub zog aerospace lossis cov khoom ua si.
Mineral Fillers (Talc, Calcium Carbonate):Txhim kho qhov seem stability thiab txo cov nqi khoom.
Tus Qauv Qauv Anatomy ntawm Kev Txhaj Tshuaj -Moulded Plastic Part
Thaum saib qhov kev cai -engineered yas ib feem- xws li ib qho khoom siv hluav taws xob, lub tshuab siv hluav taws xob, lossis lub tsev kho mob- nws yog tsim los ntawm cov qauv tshwj xeeb tsim los ua kom muaj zog, kev tsim khoom, thiab kev thov kom zoo nkauj.
1. Nominal Phab ntsa
Phab ntsa thickness yog lub hauv paus caj qaum ntawm txhua yam yas. Hauv kev tsim cov yas, kev tswj xyuas qhov tsis sib xws nominal phab ntsa thickness yog qhov tseem ceeb. Cov phab ntsa tsis sib xws ua rau kev tsim khoom tsis xws li cov cim dab dej, kev sib tsoo, thiab kev ntxhov siab sab hauv thaum lub caij txias.
2. Ribs thiab Gussets
Es tsis txhob ua cov phab ntsa tuab kom muaj zog (uas ua rau cov khoom pov tseg thiab ua rau muaj qhov tsis xws luag), cov neeg tsim qauv sivtav. Ribs yog nyias extensions protruding ntawm phab ntsa uas muab cov qauv nruj.Gussetsyog daim duab peb sab ribs siv los txhawb cov ces kaum los yog ntsug tus thawj.
3. Cov thawj coj
Tus thawj coj yog lub cylindrical protrusion siv los pab txhawb kev sib dhos ntawm cov khoom. Lawv feem ntau txais screws, threaded inserts, los yog pins. Tsim kom zoo tus thawj coj yuav tsum muaj qhov sib piv tshwj xeeb rau cov phab ntsa nominal thickness kom tsis txhob muaj qhov tsis zoo ntawm qhov pom ntawm qhov pom sab nrauv.
4. Draft Angles
Yog tias koj saib ze ntawm txhua qhov kev lag luam yas, nws cov phab ntsa ntsug tsis zoo li 90 degrees. Lawv muaj ib tug me ntsis taper hu ua alub kaum sab xis. Qhov no tso cai rau ib feem kom tshem tawm huv los ntawm kev txhaj tshuaj pwm hlau yam tsis muaj khawb lossis rub.
5. Manufacturing Features (Cov "Cov Khoom Siv")
Txhua qhov molded yas yog "nplaim" los ntawm nws qhov yug hauv lub cuab yeej pwm. Kev nkag siab txog cov khoom no pab tswj kom zoo:
Rooj vag Vestige:Lub pob me me lossis qhov tsis zoo uas cov yas molten nkag mus rau hauv pwm kab noj hniav.
Ejector Pin Marks:Cov kab me me feem ntau muab zais rau ntawm qhov tsis yog - sab hauv tshuaj pleev ib ce, sab laug los ntawm tus pins uas thawb qhov kho kom zoo tawm ntawm pwm.
Kev faib kab:Ib txoj kab faint khiav nyob ib ncig ntawm qhov chaw uas ob feem ntawm cov cuab yeej pwm tau ntsib.
Vim Li Cas Xaiv Txoj Cai "Qhov" tseem ceeb rau koj txoj kev lag luam
Thaum nrhiav cov khoom siv kev cai, kev taug kev ntawm kev sib tshuam ntawm cov tshuaj sib xyaw thiab cov cuab yeej siv tshuab tsim tuaj yeem ua rau muaj kev ntxhov siab. Xaiv cov resin tsis ncaj ncees lawm los yog tsim ib feem nrog kev hloov pauv ntawm phab ntsa tsis zoo ua rau cov khoom lag luam ntxov ntxov thiab cov peev nyiaj poob qis.
Qhov no yog qhov uas tus neeg tsim khoom lag luam paub dhau los ua qhov muaj txiaj ntsig.Tianjin SWKS Technology & Development Co., Ltdmuaj qhov kawg-rau- xaus kev cai yas thiab roj hmab tsim kev daws teeb meem. Los ntawm kev pab koj xaiv qhov zoo tshaj plaws polymer sib xyaw kom ua kom zoo dua koj cov cuab yeej tsim los ntawm kev ntsuas pwm siab dhau los, peb cov pwm kev cai - qhib kev pabcuam xyuas kom meej tias txhua yam khoom siv thiab tshuaj "ib feem" ntawm koj cov khoom yas ua haujlwm flawlessly hauv nws daim ntawv thov tiag - ntiaj teb no.
