Feem ntau cov fwj iav niaj hnub no yog tsim los ntawm kev siv cov pwm moldedpwmVim muaj ntau yam txheej txheem tsim khoom thiab cov kab ntau lawm ntev, lawv muaj qhov zoo ntawm qhov nyuaj rau tawg. Lub raj mis iav tshwj xeeb rau kev ntim cawv thiab kev hloov kho tuaj yeem tsim tau raws li pwm. Qee lub raj mis iav nrog cov duab tshwj xeeb, cov lus kos rau ntawm lub cev, lossis cov qauv yog tsim los ntawm pwm.
Ua pwmlub raj mis iavsiv dav hauv kev ua lag luam, xws li hauv kev lag luam khoom noj (xws licov fwj cawv, lub raj mis npias, lub raj mis cawv, lub raj mis dej, thiab lwm yam), kev lag luam tshuaj (xws li lub raj mis infusion, lub raj mis kua loj hauv qhov ncauj,cov fwj roj tseem ceeb, lub raj mis roj paj liab, thiab lwm yam), kev lag luam tshuaj lom neeg txhua hnub (xws liroj tseem ceeblub raj mis,lub raj mis tshuaj pleev ib ce, lub raj mis tshuaj pleev ib hnub, thiab lwm yam), thiab cov tuam txhab tsim khoom noj qab haus huv (xws li lub raj mis tshuaj blister, lub raj mis khoom noj qab haus huv, thiab lwm yam).
Cov fwj iav pwm yog tsim los ntawm kev siv pwm. Cov teeb meem xws li cov kab sib txuas pwm, cov kab pwm hauv qhov ncauj, cov kab nrib pleb hauv qab lub raj mis, tsis txaus tiv taussiab ua haujlwm sab hauv, thiab tsis txaus thermal shock tiv taus yog txhua yam tshwm sim los ntawm cov pwm tsis zoo. Yog li ntawd, qhov zoo ntawm cov pwm tuaj yeem cuam tshuam ncaj qha rau qhov zoo ntawm lub raj mis iav molded. Kev siv cov pwm tag nrho rau kev tsim khoom ua kom ntseeg tau tias qhov zoo ntawm cov pwm thiab txo qisqhov hnyav sib txawvhauv cov khoom, yog li ua kom ntseeg tau tias qhov zoo ntawm lub raj mis iav ntawm nws cov hauv paus chiv keeb. Cov pwm yog cov khoom siv tau, thiab vim yog kev hnav thiab tsim kua muag, lawv feem ntau xav tau kev saib xyuas kom ntseeg tau tias cov fwj iav tsim tawm tsis muaj teeb meem zoo.
Yog li peb feem ntau ua li cas thiaj tswj tau pwm?
Ua ntej, ntxuav pwm. Ntxuav pwm pib, tsim pwm, xuas nrig, thiabpwm qhov ncauj, thiab ntxuav txhua qhov ntawm cov pwm.Peb lub Hoobkassiv lub tshuab ntxuav qhuav kom ntev lub neej ntawm cov pwm.
Qhov thib ob, kev tshuaj xyuas thawj zaug. Xyuas qhov loj me ntawm cov lus qhia txog kev kam rau siab, ntim, thiab xeb ntawmpwm pibthiab tsim pwm rau txhua qhov kev taw qhia, thiab sau cov ntaub ntawv tseem ceeb rau ntawm daim ntawv tshuaj xyuas thiab kho pwm.
Qhov thib peb, kev saib xyuas yooj yim. Kho cov khoom puas tsuaj, ua raws li cov lus qhiatshuaj tsuag vuamnyob rau ntawmpwm kab txaij, ua qhov vuam tsuag rau txhua qhov sib txuas nruj nreem, kho qhov sib xyaw ua ke ntawm cov pwm pib thiab lub hauv paus, zeb thiab daws qhov sib xyaw ua ke ntawm lub qhov ncauj pwm, thiab luam tawm thiab rho tawm lub hau ntswj rau ntawm qab pwm. Txhuam cov pwm thiab lub qhov ncauj pwm.
Qhov thib plaub, kev tshuaj xyuas zaum kawg. Tom qab kho cov pwm pib thiab cov pwm tsim tiav lawm, siv lub micrometer, ib qhovernier caliper, thiab iblub ntsuas qhov txuas xovraukev tshuaj xyuas zaum kawg.
Qhov saum toj nocov txheej txheem txij nkawmtxawv me ntsis ntawm kev saib xyuas cov pwm raws sijhawm thaum lub sijhawm tsim khoom lossis kev npaj cov pwm rau kev hloov pauv. Nws yog ib qho tseem ceeb uas yuav tsum rov xyuas dua cov pwm uas tau kho ua ntej lossis cov pwm tag nrho ua ntej teeb tsa rau ntawm lub tshuab ua lub raj mis. Txhawm rau kom ntseeg tau tias tus qauv tsim khoom ntseeg tau, txhua yam tseem ceeb thiab cov yam ntxwv tseem ceeb yuav tsum sib xws nrog cov qauv tsim thiab cov qauv qub.
Tshwj xeeb, thaum tsim cov fwj sib dua hauv lub Hoobkas fwj iav, yuav tsum tau them sai sai rau cov khoom siv ntawm cov pwm thiab cov khoom siv. Piv txwv li, cov khoom siv punch siv rau lub qhov ncauj nias tshuab yuav tsum ntseeg tau txaus. Yog tias cov hlau sab hauv ntawm qhov chaw ntawm lub punch poob tawm, nws yuav lo rau sab hauv ntawm lub raj mis khoob, ua rau "qhov dub"thiab txo qis qhovkev cuam tshuam tsis kamthiab lwm yamcov kev ua tau zoo ntawm lub cevntawm lub raj mis iav molded.
