Ntu 2 ntawm 3: Txheej nrog cov yas
Kauj Ruam 1. Txhuam rau ib txheej kua kua nplaum
Mus ob peb centimeters dhau los ntawm cov khoom ntug los tsim lub flange. Thawj txheej no yuav yog cov pwm nto kom ntseeg tau tias tsis muaj cua npuas. Cia cov txheej no kom qhuav li 30 feeb.
Kauj Ruam 2. Txhuam ntau txheej ntawm cov yas
Tso cai rau txhua txheej kom qhuav ua ntej thov daim ntawv tom ntej. Ntau txheej ntawm cov yas yuav ua rau muaj cov pwm muaj zog dua. Rau cov khoom me me, plaub lossis tsib txheej yuav txaus. Cov khoom loj yuav xav tau kaum lossis ntau txheej.
Tsis txhob cia cov yas kom qhuav thaum hmo ntuj ntawm cov txheej. Qhov no yuav kho cov pwm thiab ua rau txheej txheej tom ntej tsis sib raug zoo
Kauj Ruam 3. Ntxiv cov khoom txhawb ntxiv
Yog tias koj tab tom ua cov khoom loj dua, koj yuav xav tau qee cov ntaub ntawv ntxiv los tsim cov pwm khov. Cov ntaub xoob xoob xws li ntaub qhwv ntaub ua haujlwm tau zoo. Ntub nws nrog cov yas thiab siv rau thaj chaw uas zoo li yuav nthuav tawm ntawm cov duab thaum cov pwm puv nrog qhov nruab nrab casting. Tsis txhob txhawb qhov chaw uas yuav tsum tau ncab kom pab tau cov khoom tso tawm los ntawm cov pwm.
Cov pwm zoo li yuav ncab thiab deform ze rau hauv qab ntawm cov pwm (uas yog qhov zoo tshaj plaws ntawm qhov khoom). Qhov no yog vim nws yuav tsum txhawb nqa qhov hnyav ntawm koj cov khoom siv casting
Ntu 3 ntawm 3: Tiav Koj Cov Pwm
Kauj Ruam 1. Cia cov pwm qhuav ib hmo lossis ntev dua thaum ua tiav

Kauj Ruam 3. Tsim kom muaj kev txhawb nqa rau pwm
Rau feem ntau cov khoom, nws yog qhov zoo tshaj los txhawb cov pwm nyob hauv qab lub flange kom nws raug ncua. Cov khoom loj dua tuaj yeem xav tau kev txhawb nqa ntxiv xws li lub thawv ntoo kom khaws nws kom zoo thaum tsim nyog.
