Dab tsi yog cov txheej txheem ntawm cov yas molding?

1) Pretreatment (yas ziab los yog ntxig preheat kho)

2) tsim

3) Machining (yog tias xav tau)

4) Retouching (de-flashing)

5) Kev sib dhos (yog tias tsim nyog) Ceeb toom: tsib txheej txheem saum toj no yuav tsum tau ua tiav thiab tsis tuaj yeem thim rov qab.

Yam tseem ceeb cuam tshuam rau qhov tseeb qhov tseeb ntawm yas molding:

1) Kev cuam tshuam ntawm shrinkage tus nqi ntawm raw khoom

Qhov ntau dua qhov shrinkage ntawm cov khoom siv raw, qhov qis dua qhov precision ntawm cov khoom. Tom qab cov khoom siv yas tau ntxiv dag zog los yog hloov kho nrog inorganic filling, nws cov shrinkage tus nqi yuav raug txo los ntawm 1-4 zaug. Yas shrinkage ua tej yam kev mob (txias tus nqi thiab txhaj tshuaj, kev ua, thiab lwm yam), cov khoom tsim thiab pwm tsim thiab lwm yam. Qhov tseeb ntawm kev sib txawv molding yog nyob rau hauv nqe lus txiav txim: txhaj tshuaj molding > extrusion > txhaj tshuab moulding > extrusion tshuab moulding > compression molding > calender molding > nqus tsev

2) Kev cuam tshuam ntawm cov khoom raw creep (creep yog deformation ntawm cov khoom nyob rau hauv kev ntxhov siab). General: Cov ntaub ntawv yas uas muaj kev nkag siab zoo: PPO, ABS, PC thiab cov khoom siv ntxiv lossis cov khoom hloov kho. Tom qab cov khoom siv yas tau ntxiv dag zog los yog hloov kho nrog inorganic filling, nws cov creep kuj yuav zoo heev.

3) Kev cuam tshuam ntawm linear expansion ntawm raw khoom: linear expansion coefficient (thermal expansion coefficient)

4) Kev cuam tshuam ntawm kev nqus dej ntawm cov khoom siv raw: Tom qab nqus dej, qhov ntim yuav nthuav dav, ua rau muaj qhov loj me, uas cuam tshuam rau qhov tseeb qhov tseeb ntawm cov khoom. (Kev nqus dej ntawm cov khoom siv raw kuj tseem cuam tshuam rau lub cev thiab lub zog ntawm cov khoom siv raw tom qab lawv ua tiav rau hauv qhov chaw.)

Cov yas uas muaj dej nqus dej siab: xws li: PA, PES, PVA, PC, POM, ABS, AS, PET, PMMA, PS, MPPO, PEAK Ua tib zoo saib xyuas cov khoom ntim thiab ntim ntawm cov yas no.

5) Kev cuam tshuam ntawm o ntawm raw cov ntaub ntawv Ceev faj! ! Qhov hnyav tsis kam ntawm cov khoom siv raw yuav cuam tshuam rau qhov tseeb qhov tseeb ntawm cov khoom thiab lub cev thiab lub zog ntawm cov khoom. Rau cov khoom yas hauv kev sib cuag nrog tshuaj lom neeg, siv cov ntaub ntawv yas uas nws cov xov xwm tsis tuaj yeem ua rau lawv o.

6) Kev cuam tshuam ntawm kev muab tub lim: Tom qab cov khoom siv yas tau ntxiv dag zog lossis hloov kho los ntawm cov khoom siv tsis huv, qhov tseeb qhov tseeb ntawm cov khoom yas tuaj yeem txhim kho.
