Taw qhia
Cov cuab yeej kho mob yog ib feem tseem ceeb ntawm kev lag luam kho mob, ua lub luag haujlwm tseem ceeb hauv kev kuaj mob, saib xyuas, thiab kho cov neeg mob. Kev txhaj tshuaj molding yog cov txheej txheem tsim khoom siv dav siv los tsim cov khoom siv kho mob zoo. Nws koom nrog kev txhaj tshuaj molten yas rau hauv pwm kab noj hniav, uas tom qab ntawd solidifies thiab siv cov pwm pwm. Kab lus no tham txog cov txheej txheem ntawm kev txhaj tshuaj molding cov cuab yeej kho mob kom ntxaws.
Cov khoom siv hauv Kev Txhaj Tshuaj Molding Cov Khoom Siv Kho Mob
Kev xaiv cov ntaub ntawv siv rau kev txhaj tshuaj molding yog nyob ntawm daim ntawv thov thiab cov lus qhia tshwj xeeb ntawm cov cuab yeej kho mob tau tsim. Cov khoom siv yuav tsum muaj kev nyab xeeb, tsis muaj tshuaj lom, thiab muaj peev xwm tiv taus qhov hnyav ntawm qhov chaw kho mob.
Cov thermoplastics
Thermoplastics ua rau feem ntau ntawm cov khoom siv hauv kev txhaj tshuaj molding khoom siv kho mob. Nws yog hom yas uas tuaj yeem yaj thiab rov molded ntau zaus yam tsis poob nws cov khoom. Qee cov khoom siv thermoplastic feem ntau siv rau kev kho mob muaj xws li:
- Polypropylene: Nws yog feem ntau siv los tsim cov khoom siv hauv chav kuaj, ntim khoom, thiab ntim khoom kho mob.
- Polycarbonate: Nws yog cov yas uas muaj zog thiab pob tshab siv los tsim cov cuab yeej kho mob thiab khoom siv, suav nrog cov hlab ntshav thiab cov thawv kho mob.
- Polyurethane: Nws yog ntau yam khoom siv los tsim cov catheters, tubing, thiab lwm yam khoom siv kho mob.
- Nylon: Nws yog feem ntau siv los tsim cov phais phais, pob txha taub hau, thiab lwm yam kev cog lus kho mob.
Silicones
Silicones kuj tseem siv rau hauv kev txhaj tshuaj molding khoom siv kho mob. Lawv yog hom elastomer, txhais tau tias lawv muaj ob qho tib si yas thiab roj hmab zoo li cov khoom. Qee cov khoom siv silicone muaj xws li:
- Liquid silicone roj hmab (LSR): Nws yog pob tshab thiab hloov tau yooj yim silicone siv los tsim cov khoom siv kho mob xws li catheters, seals, thiab gaskets.
- Cov roj hmab sib xws (HCR): Nws yog cov khoom siv silicone siv rau kev tsim cov khoom cog, cov ntsaws ruaj ruaj, thiab gaskets.
Cov txheej txheem ntawm Txhaj Molding Cov Khoom Siv Kho Mob
Txoj kev txhaj tshuaj molding muaj ob peb kauj ruam, suav nrog kev tsim cov cuab yeej, xaiv cov khoom siv, kev teeb tsa pwm, txhaj tshuaj, thiab tom qab ua tiav. Cov hauv qab no yog cov ncauj lus kom ntxaws txog kev txhaj tshuaj molding khoom siv kho mob:
Tooling Tsim
Cov txheej txheem tsim cov cuab yeej suav nrog kev tsim cov cuab yeej (pwm) uas yuav siv los ua cov khoom siv yas molten. Tus qauv tsim yuav tsum muaj nyob rau hauv cov khoom kawg cov duab, qhov loj me, thiab kev ua haujlwm. Nws tseem yuav tsum xyuas kom yooj yim ejection ntawm cov khoom kawg thiab cov khoom pov tseg yam tsawg kawg nkaus.
Kev xaiv khoom
Kev xaiv cov khoom siv ua lub luag haujlwm tseem ceeb hauv qhov zoo ntawm cov khoom kawg. Cov khoom siv yuav tsum ua tau raws li cov lus qhia tshwj xeeb uas yuav tsum tau ua rau daim ntawv thov tshwj xeeb. Nws tseem yuav tsum muaj kev nyab xeeb, tsis muaj tshuaj lom, thiab biocompatible.
Pwm teeb
Lub pwm teeb tsa theem yuav txhim kho cov pwm rau hauv lub tshuab txhaj tshuaj molding. Cov theem no yuav tsum tau muaj tseeb raws li cov pwm qhov chaw yuav txiav txim siab cov khoom kawg cov duab thiab zoo.
Txhaj tshuaj
Thaum cov pwm nyob rau hauv qhov chaw thiab cov khoom yas tau ntim rau hauv lub tshuab txhaj tshuaj molding, lub sijhawm txhaj tshuaj pib. Lub tshuab lub cev muaj zog tsav cov ntsia hlau uas thawb cov yas molten los ntawm lub nozzle rau hauv pwm kab noj hniav. Lub siab yog siv los xyuas kom meej cov khoom yas ntim tag nrho cov ces kaum ntawm pwm kab noj hniav.
Txias
Tom qab cov khoom siv yas txhaj rau hauv pwm, nws sab laug kom txias thiab khov. Lub caij txias yuav tsum tau ua tib zoo tswj qhov kub kom tsis txhob muaj kev sib tsoo lossis tawg ntawm cov khoom kawg.
Tshem tawm
Thaum cov khoom siv yas tau txias txaus thiab ruaj khov, nws yog lub sijhawm rau ejection cov khoom kawg los ntawm pwm. Cov theem no yuav tsum tau ua tib zoo tuav kom tsis txhob muaj kev puas tsuaj rau cov khoom kawg.
Tom qab ua tiav
Cov theem kawg suav nrog kev tshuaj xyuas, kuaj, thiab ntim cov khoom siv kho mob. Txhua yam khoom siv yuav tsum tau kuaj xyuas kom paub tseeb tias lawv ua tau raws li cov qauv kev nyab xeeb thiab kev ua haujlwm uas yuav tsum tau ua. Tom qab ntawd lawv tau ntim thiab sau npe rau kev xa khoom.
Xaus
Kev txhaj tshuaj molding yog txheej txheem tsim khoom tseem ceeb rau kev tsim cov khoom siv kho mob zoo. Kev xaiv cov ntaub ntawv raug, tsim cov cuab yeej, thiab kev tswj hwm ntawm txhua kauj ruam hauv cov txheej txheem ua kom cov cuab yeej kho mob muaj kev nyab xeeb thiab ua haujlwm. Nrog rau qhov kev thov rau cov cuab yeej kho mob loj hlob tuaj, kev txhaj tshuaj molding yuav txuas ntxiv yog cov txheej txheem tseem ceeb hauv kev lag luam kho mob.
