Kev siv cov yas pwm

1. Piv txwv li, nyob rau hauv ntau yam xws li cov khoom siv hauv tsev, cov cuab yeej siv thiab cov ntsuas, cov cuab yeej tsim kho, kev lag luam tsheb, thiab cov khoom siv niaj hnub, qhov feem ntawm cov khoom yas yog nce sai heev. Cov khoom siv yas tsim tau zoo tuaj yeem hloov tau ntau yam khoom siv hlau. Cov qauv ntawm plasticization ntawm cov khoom lag luam thiab cov khoom siv niaj hnub niaj hnub yog nce ntxiv.
2. Cov ntsiab lus dav dav ntawm pwm: Hauv kev tsim khoom, ntau lub tshuab xovxwm thiab cov cuab yeej tshwj xeeb mounted ntawm cov tshuab xovxwm yog siv los tsim cov khoom lossis cov khoom ntawm cov duab uas xav tau los ntawm cov hlau lossis cov khoom tsis yog hlau los ntawm kev siab. Cov cuab yeej tshwj xeeb no suav nrog hu ua pwm.
3. Txhaj tshuaj molding txheej txheem piav qhia: Pwm yog cov cuab yeej tsim khoom yas.
4. Kev faib tawm dav dav ntawm cov pwm: tuaj yeem muab faib ua cov pwm yas thiab cov pwm tsis yog yas:
Cov pwm uas tsis yog yas muaj xws li casting pwm, forging pwm, stamping pwm, tuag-casting pwm, thiab lwm yam.
A. Casting pwm - faucet, npua hlau platform
B. Forging tuag - tsheb lub cev
C. Stamping tuag - lub computer vaj huam sib luag
D. Tuag casting pwm - superalloys, lub tog raj kheej thaiv
⑵ Cov pwm yas muab faib ua:
A. Txhaj tshuaj molding pwm - TV casing, keyboard khawm (feem ntau siv)
B. Tshuab pwm - lub raj mis haus
C. Compression molding pwm - hluav taws xob ntoo hloov, scientific porcelain tais thiab phaj
D. Hloov moulding pwm - cov khoom siv sib xyaw ua ke
E. Extrusion molding pwm - kua nplaum raj, hnab yas
F. Kub forming pwm - pob tshab tsim ntim lub plhaub
G. Rotating molding pwm - Mos roj hmab menyuam roj hmab cov khoom ua si
Kev txhaj tshuaj molding yog txoj kev siv ntau tshaj plaws hauv kev ua cov yas. Txoj kev no siv tau rau tag nrho cov thermoplastic plastics thiab qee cov thermosetting plastics, thiab qhov ntau ntawm cov khoom yas tsim yog tsis sib haum los ntawm lwm txoj kev molding. Raws li ib qho ntawm cov cuab yeej tseem ceeb rau kev txhaj tshuaj molding ua, cov pwm txhaj tshuaj muaj qib siab ntawm qhov raug zoo, lub voj voog tsim khoom, thiab kev ua haujlwm ntawm cov txheej txheem txhaj tshuaj molding, uas cuam tshuam ncaj qha rau qhov zoo, tso zis, nqi, thiab cov khoom hloov tshiab ntawm cov khoom, thiab tseem txiav txim siab txog kev muaj peev xwm thiab kev ceev ntawm kev lag luam hauv kev sib tw ua lag luam.
