1. Txhaj tshuaj molding yog ib txoj hauv kev tsim molding ntawm cov khoom lag luam. Cov khoom lag luam feem ntau yog tsim los ntawm kev txhaj tshuaj yas thiab yas. Txhaj tshuaj molding tseem tuaj yeem muab faib ua kev txhaj tshuaj molding thiab tuag casting. Txhaj tshuaj molding tshuab (xa mus rau lub tshuab txhaj tshuaj lossis tshuab moulding tshuab) yog cov khoom siv thermoplastic lossis thermosetting siv yas mould pwm rau ntau yam duab ntawm cov khoom yas ntawm cov khoom siv tseem ceeb, kev txhaj tshuaj yog dhau los ntawm kev txhaj tshuaj tshuab thiab pwm kom ua tiav.
2. Nws yog txheej txheem txheej txheem uas cov khoom siv extrusion tau ua los ntawm ntau yam khoom hla ntu lossis cov khoom ib nrab los ntawm lub tshuab extrusion los ntawm kev ua ntawm cov raj extrusion thiab cov ntsia hlau thaum raug rhaub thiab yas, thiab thawb rau pem hauv ntej los ntawm cov ntsia hlau .
3. Tshuab moulding, tseem hu ua hollow tshuab moulding, yog txheej txheem yas ua sai sai. Cov raj yas yas uas tau txais los ntawm kev txau lossis txhaj tshuaj molding ntawm cov thermoplastic cob tau muab tso rau hauv cov pwm sib cais thaum nws kub (lossis ua kom sov mus rau lub xeev muag muag), thiab cov huab cua tau txhaj rau hauv daim ntawv tam sim tom qab pwm raug kaw kom ua yas billet tshuab thiab lo rau sab hauv phab ntsa ntawm cov pwm. Tom qab txias thiab demoulding, ntau yam khoom hollow tau txais.
4. Blister yog ib hom yas ua tshuab. Lub hauv paus ntsiab lus yog kom ua kom cov yas yas tiaj los ntawm cua sov, nqus nws ntawm cov pwm los ntawm lub tshuab nqus tsev, thiab tsim nws tom qab txias, thiab siv rau txhua txoj kev ntawm lub neej.
5. Mould nias molding, tseem hu ua nias molding lossis compression molding, yog thawj cov hmoov, cov yas lossis cov yas fibrous rau hauv qhov kub thiab txias ntawm pwm kab noj hniav, thiab tom qab ntawd kaw cov pwm siab thiab ua rau nws ua haujlwm thiab ua haujlwm kho. Mould molding kuj tseem tuaj yeem siv rau thermosetting plastics, thermoplastics thiab cov khoom siv roj hmab.
