Lub tshuab txhaj tshuaj molding yog siv rau kev txhaj tshuaj molding nrog cov pwm hlau, uas hais tias pwm muaj kab noj hniav uas muaj kab noj hniav nyob rau hauv cov pwm qis thiab pwm sab sauv, uas yog ib qho channel tsim los ntawm ib qho kev txiav txim siab nyob rau hauv cov kab noj hniav ntawm cov pwm qis ze ntawm qhov inlet rau txhaj molten resin (P) rau hauv kab noj hniav. Cov qhov qhib ntawm cov channel raug them tag nrho, tsim cov cua txias nruab nrab ntws channel kom cov cua txias nruab nrab (xws li cua txias) tau nkag rau hauv qhov nkag, ntws los ntawm cov channel thiab tawm ntawm qhov hluav taws xob. Cov pwm qis thiab sab saud yog ua los ntawm txhuas lossis aluminium alloy. Qhov chaw xaiv ntawm cov kab noj hniav, uas yog nyob rau hauv kev sib cuag ncaj qha nrog cov molten resin, yog sandblasted los yog tshuaj kho los tsim cov pob me me.
Hlau Powder Txhaj Moulding (MIM) yog cov hmoov metallurgy tshiab nyob ze-net-shape thev naus laus zis uas tau qhia txog niaj hnub yas txhaj tshuaj molding rau hauv cov hmoov metallurgy.
Cov pwm hlau yog qhia hauv qab no:
Cov txheej txheem yog raws li nram no: Thaum xub thawj, cov hmoov thiab cov organic binder yog uniformly tov, thiab ces txhaj rau hauv pwm kab noj hniav los ntawm kev txhaj tshuaj molding tshuab nyob rau hauv rhuab plasticizing xeev (~ 150 ℃), thiab ces cov binder nyob rau hauv lub forming dawb paug yog muab tshem tawm los ntawm cov tshuaj los yog thermal decomposition txoj kev, thiab thaum kawg cov khoom kawg yog tau los ntawm sintering thiab densification. Txheej txheem: binder → sib tov → txhaj tshuaj → degreasing → sintering → tom qab kho.
Kev txhaj tshuaj pwm yog ib qho cuab yeej rau kev tsim cov khoom yas thiab yog qhov lav ntawm lawv cov qauv ua tiav thiab qhov ntev. Txhaj tshuaj molding yog ib txoj hauv kev ua haujlwm siv hauv kev tsim khoom loj ntawm qee yam zoo li lub cev. Nws tshwj xeeb yog hais txog kev txhaj tshuaj ntawm cov khoom siv hluav taws xob (los ntawm kev kub siab rau hauv pwm kab noj hniav, tom qab txias thiab kho, kom tau txais cov khoom tsim. Hlau hmoov txhaj tshuab siv cov hmoov hlau txhaj tshuaj molding tshuab molding khoom, kuj muaj cov cuab yeej sib txawv.
