Kev txhaj tshuaj pwm, uas peb hu ua pwm txias khiav pwm, ua tiav tom qab txhaj ib zaug. Tom qab qhib lub pwm, yuav muaj ib txoj kev txias thiab solidification txaus txoj kev uas yuav tsum tau coj tawm manually los yog neeg kho tshuab. Cov pwm ntawd nrog cov kub khiav tshuab (nrog rau cov kub khiav dej kub, sib cais kub kub, lub tshuab ua kom sov, cov khaub thuas sib tw kub kub, thiab lwm yam.) Hu ua kub khiav tawm pwm.
Qhov zoo ntawm cov kub khiav pwm txhaj piv rau kev sib tw khiav txias pwm yog:
1 Thaum cov phab ntsa tuab ntawm cov khoom yog nyias, xyuas kom meej tias cov yaj tuaj yeem mus txog qhov chaw deb ntawm lub rooj vag (chaw nres nkoj pub noj), zoo heev txo cov degree ntawm cov khoom deformation, zoo heev txhim kho qhov khoom zoo thiab qhov sib xws ntawm cov khoom.
2 Lub siab poob hauv cov channel ntws yog me me, melt fluidity yog qhov zoo, qhov ceev tau yooj yim rau qhov tsis sib xws, thiab cov tsis xws luag xws li deformation ntawm qhov txhaj moulded feem, batch ncov, qhov tsis zoo thiab qhov chromatic aberration yog zam.
3 Tag nrho lossis feem ntau ntawm cov khoom siv tshem tawm (dej nozzle), tsis tas yuav txiav tus kheej nozzle, tsis tas yuav tsoo, txhim kho kev siv cov ntaub ntawv, txuag lub zog thiab txhim kho kev ua haujlwm.
4 Txhawm rau tshem tawm cov cua kub ntxiv los ntawm cov pov tseg, lub voj voog txias ntawm lub pwm tsuas yog lub sijhawm txias ntawm cov yas, luv lub voj voog ua.
5 Cov neeg khiav kub tau txiav lub rooj vag txhawm rau txhim kho cov tsos ntawm lub rooj vag thiab txhim kho lub tshuab ua kom tiav.
6 Muaj kev tswj fwm qhov kub ntawm cov melt yas, tshem tawm qhov kev puas tsuaj ntawm cov khoom, ua lub sijhawm nyob hauv kev tsim nyog thiab txo qhov kev ntxhov siab sab hauv ntawm cov khoom.
Vim tias cov kev zoo no ntawm cov txheej txheem kub khiav, hauv cov teb chaws tsim xws li Europe, Tebchaws Asmeskas, thiab Nyij Pooj, ntau tshaj li 70% kev txhaj tshuaj pwm siv cov txheej txheem kub khiav.
Kev faib tawm ntawm kub khiav
Qhib hom
Cov qauv qhib yog yooj yim, cov khoom siv muaj qhov kev txwv siab, kev kos duab thiab cov dej xau tuaj yeem yooj yim tshwm sim, qhov zoo tshaj plaws tsis zoo, thiab daim ntawv thov tsawg dua nyob rau hauv cov pwm siab ua haujlwm nyob hauv cov teb chaws txawv teb chaws, thiab tib lub koom haum pwm tuaj yeem sib xyaw. nrog rab koob valve hom ntawm cov tuam ntxhab sib txawv. Ntau lub tuam txhab tuaj yeem ua rau lawv tus kheej.
Koob koob yam
Koob valve hom kub khiav cov ntaub ntawv txuag, qhov saum npoo ntawm cov yas yog qhov zoo nkauj, thiab sab hauv yog zoo thiab lub zog yog siab.
