Silver txoj hlua khi ntawm kev txhaj tshuaj molding cov khoom muaj xws li cov pa hluav taws xob sab hauv (feem ntau cov pa roj, roj av) {1} Qhov laj thawj tseem ceeb yog tshuaj xyuas raws li nram no:
.} tshuab theem:
(1) Lub thoob thiab ntsia hlau raug puas lossis roj hmab lub taub hau thiab cov roj hmab nplhaib muaj cov ntaub muag digital dig, uas yog decomposed los ntawm lub sijhawm ntev cua sov.
(2) Cov txheej txheem cua sov tsis tawm ntawm kev tswj hwm, ua rau qhov kub thiab txias ua rau muaj cov cua sov thiab cov cua sov {.
B . mould:
(1) tso tawm tsis zoo .
(2) Kev sib txhuam tsis kam ntawm kev khiav, rooj vag, thiab kab noj hniav hauv cov pwm loj, ua rau ib nrab overheating thiab decomposition.
(3) Lub rooj vag thiab kab noj hniav tsis sib xws
(4) Dej Seeps mus rau hauv cov txias channel rau hauv kab noj hniav .
C . yas yas:
(1) Yas muaj cov av noo ntau, cov phom sij ntau dhau los yog cov phom sij tas mus li, cov yas yuav tsum tau muab tshem tawm tag nrho thiab cov khib nyiab yuav tsum muab tshem tawm .
(2) nws abrathbs cov as-ham los ntawm huab cua lossis nqus cov xim zoo los ntawm cov xim tsis muaj xim. Nws yog qhov zoo tshaj plaws rau nruab ib lub tshuab ziab khaub ncaws ntawm lub tshuab ntawm lub tshuab {}}
(3) Tus nqi ntawm cov roj nplua nyeem thiab cov tuab dua rau cov yas yog ntau dhau los yog qhov sib xyaw ua ke yog kom muaj zog, nws kuj yuav decomepose, nws kuj tseem yuav decompose.
(4) Cov yas yog qhov tsis huv thiab sib tov nrog lwm cov plastics .
D . txheej qib theem:
(1) When the set temperature, pressure, speed, back pressure, and melt motor speed are too high to cause decomposition, or when the pressure, speed, injection time, holding pressure, and back pressure are too low, because high pressure cannot be obtained, the density is insufficient, and the gas cannot be melted. The appropriate temperature, pressure, speed and time should be set, and a multi-stage injection rate should be adopted.
(2) qis rov qab siab thiab nrawm nrawm nrawm tuaj yeem yooj yim ua rau huab cua nrog ntev dhau lawm, ua rau muaj kev sib tw ntev dhau, ua rau kev txiav txim siab tsis ntev, ua rau kev txiav txim siab.
(3) Cov khoom siv tsis txaus
Qhov kev siv txiaj ntsig zoo rau Weld Seams hauv kev txhaj tshuaj molding
Thaum lub molten yas tau ntsib qhov ntxig qhov, thaj chaw nrog cov pwm uas ntim tau zoo li, nws tsis tuaj yeem ua rau weld
. txheej qib theem:
(1) Kev txhaj tshuaj siab thiab nrawm yog tsawg heev, thiab cov tawv nqaij kub thiab cov pwm kub tsis tshua muaj zog, ua rau txias rau thaum ntxov thiab lub ntsej muag weld kom tshwm sim.
(2) Thaum txhaj tshuaj thiab nrawm yog siab dhau, yuav muaj tshuaj txau thiab weld seams.
(3) nce kev hloov nrawm, nce rov qab siab, txo qhov viscosity ntawm cov yas, thiab nce lub ntom ntom.
(4) Cov yas yuav tsum tau muab cov ntaub ntawv ua haujlwm kom qhuav thiab siv tsawg dua.}}}}} .
(5) txo lub zog clamping thiab pab txhawb kev tso tawm .
b . mould:
(1) Muaj ntau lub rooj vag nyob rau hauv tib kab noj hniav zoo ib yam {} Lub rooj vag yuav tsum raug txo lossis teeb tsa cov kev sib tw, lossis kom ze rau weld li sai tau.
(2) Lub pa tawm ntawm Weld yog neeg pluag, thiab kev tso sab nraud yuav tsum tau teeb tsa .
(3) Kev nchuav yog loj heev, cov pouring system specification yog tsis tsim nyog los ntawm ntws ib ncig ntawm cov ntxig, lossis cov ntxig yuav tsum tau siv kom tau tsawg li sai tau .
(4) Cov kev hloov tuab heev yog loj heev, los yog cov tuab tuab dhau lawm, thiab cov khoom tuab yuav tsum tau sib xyaw .
(5) Yog tias tsim nyog, ib txoj kev siv vuam zoo yuav tsum tau teeb tsa ntawm Weld sib koom ua ke cais cov khoom weld los ntawm cov khoom .
c . yas yas:
(1) Lubricants thiab cov tuab yuav tsum tau qhia rau hauv cov plastics nrog cov fluidity tsis zoo lossis kub kub ua tau ntau li ntau tau.
(2) Yas muaj ntau yam impurities thiab yuav tsum tau hloov nrog zoo zoo yas thaum tsim nyog.
