Kev tshuaj xyuas qhov tsis xws luag rau kev txhaj tshuaj molded qhov chaw thiab Yuav ua li cas peb tuaj yeem txhim kho

txhim kho 1

Kev puas tsuaj 1. Tsis muaj cov khoom siv

A. Defect vim li cas:

Cov khoom me me thiab cov ces kaum ntawm cov khoom tiav tsis tuaj yeem tsim tau tag nrho, vim kev ua haujlwm tsis zoo ntawm cov pwm lossis cov pa tawm tsis zoo, thiab cov qauv tsim tsis zoo (cov phab ntsa tuab tsis txaus) vim tsis txaus txhaj tshuaj lossis siab hauv molding.

B. Pwm txhim kho kev ntsuas:

Kho cov pwm qhov twg cov khoom ploj lawm, coj los yog txhim kho cov pa ntsuas, ua kom cov khoom tuab, thiab txhim kho lub rooj vag (loj lub rooj vag, nce lub rooj vag).

C. Kev txhim kho molding:

Ua kom cov koob txhaj tshuaj, nce qhov txhaj tshuaj, thiab lwm yam.

Qhov tsis xws luag 2. shrinkage

A. Defect vim li cas:

Nws feem ntau tshwm sim nyob rau hauv qhov tsis sib xws ntawm phab ntsa tuab lossis cov khoom tuab ntawm cov khoom molded, uas yog tshwm sim los ntawm qhov sib txawv ntawm qhov txias txias los yog solidification shrinkage ntawm cov yas kub yaj, xws li sab nraub qaum, cov npoo nrog sab phab ntsa, thiab sab nraub qaum ntawm BOSS txhua.

B. Pwm txhim kho kev ntsuas:

Txo cov khoom tuab, tab sis khaws tsawg kawg 2/3 ntawm cov khoom tuab;thicken tus khiav thiab nce lub rooj vag;add tso.

C. Kev txhim kho molding:

Ua kom cov khoom kub, ua kom lub zog txhaj tshuaj, ncua lub sijhawm tuav lub sijhawm, thiab lwm yam.

Qhov tsis zoo 3: Cov qauv huab cua

A. Defect vim li cas:

Muaj tshwm sim ntawm lub rooj vag, feem ntau vim tias cov pwm kub tsis siab, qhov kev txhaj tshuaj ceev thiab siab siab dhau lawm, lub rooj vag tsis raug teeb tsa kom zoo, thiab cov yas ntsib cov qauv turbulent thaum pouring

B. Pwm txhim kho kev ntsuas:

Hloov cov sprue, polish tus khiav, nthuav cov khoom txias ntawm cov neeg khiav dej num, nthuav cov sprue, thiab ntxiv kev ntxhib los mos rau saum npoo (koj tuaj yeem kho lub tshuab lossis kho pwm kom ntes cov kab sib txuas).

C. Kev txhim kho molding:

Ua kom pwm kub, txo kev txhaj tshuaj nrawm, txo txhaj tshuaj, thiab lwm yam.

Tsis zoo 4. Deformation

A. Defect vim li cas:

Cov khoom me me, nyias-walled qhov chaw nrog thaj tsam loj, lossis cov khoom tiav loj nrog cov qauv asymmetric yog tshwm sim los ntawm qhov tsis sib xws ntawm kev ntxhov siab los yog sib txawv ejection quab yuam thaum molding.

B. Pwm txhim kho kev ntsuas:

Kho qhov thimble;teeb tsa tus pin tensioning, thiab lwm yam;yog tias tsim nyog, ntxiv cov txiv neej pwm los kho qhov deformation.

C. Kev txhim kho molding:

Kho cov pwm kub ntawm cov txiv neej thiab poj niam pwm kom txo tau lub siab tuav, thiab lwm yam. (Qhov kev hloov ntawm qhov deformation ntawm cov me me feem ntau yog nyob ntawm lub siab thiab lub sij hawm, thiab kev hloov ntawm deformation ntawm qhov loj feem ntau yog nyob ntawm pwm kub. )

Tsis zoo 5. Qhov saum npoo tsis huv

A. Defect vim li cas:

Qhov saum npoo ntawm pwm yog ntxhib.Rau cov khoom siv PC, qee zaum vim muaj pwm kub, muaj cov kua nplaum seem thiab cov roj stains ntawm cov pwm saum npoo.

B. Pwm txhim kho kev ntsuas:

Ntxuav qhov tuag saum npoo thiab polish nws.

C. Kev txhim kho molding:

Txo cov pwm kub, thiab lwm yam.

Tsis zoo 6. Stomata

A. Defect vim li cas:

Pob tshab tiav cov khoom PC yog yooj yim tshwm sim thaum molding, vim hais tias cov roj tsis tas thaum lub sij hawm txhaj tshuaj molding txheej txheem, tsis tsim pwm tsim los yog tsis zoo molding tej yam kev mob yuav muaj kev cuam tshuam.

B. Pwm txhim kho kev ntsuas:

Ua kom cov pa tawm, hloov lub rooj vag (nce lub rooj vag), thiab cov khoom siv PC khiav yuav tsum tau polished.

C. Kev txhim kho molding:

Cov txheej txheem ziab kom qhuav, ua kom lub zog txhaj tshuaj, txo kev txhaj tshuaj nrawm, thiab lwm yam.

Defect 7. Tawm ntawm qhov ntev tolerences

A. Defect vim li cas:

Teeb meem nrog pwm nws tus kheej, los yog tsis tsim nyog molding tej yam kev mob ua rau lub molding shrinkage tsis tsim nyog.

B. Pwm txhim kho kev ntsuas:

Kho cov pwm, xws li ntxiv cov kua nplaum, txo cov kua nplaum, lossis txawm tias rov qhib cov pwm hauv qhov xwm txheej hnyav (tus nqi shrinkage tsis tsim nyog ua rau ntau qhov sib txawv).

C. Kev txhim kho molding:

Feem ntau, hloov lub sijhawm tuav thiab kev txhaj tshuaj siab (theem thib ob) muaj qhov cuam tshuam loj tshaj plaws ntawm qhov loj.Piv txwv li, nce qhov kev txhaj tshuaj siab thiab ua kom lub siab tuav thiab pub mis tuaj yeem ua kom qhov loj me, lossis txo cov pwm kub, ua kom lub rooj vag lossis nce lub rooj vag tuaj yeem txhim kho cov kev cai.
