ABS Ntawv Khoom Thiab Pwm Tsim

1. Phab ntsa tuab ntawm cov khoom

Phab ntsa tuab ntawm cov khoom yas ABS muaj feem cuam tshuam nrog qhov ntev ntws ntawm cov yaj, kev ua haujlwm tau zoo, thiab kev siv. Qhov piv ntawm qhov siab tshaj plaws ntws ntev ntawm ABS yaj rau phab ntsa tuab ntawm cov khoom yog li 190: 1. Tus nqi no yuav txawv nrog qib sib txawv. Yog li ntawd, phab ntsa tuab ntawm cov khoom ABS yuav tsum tsis txhob tuab heev. Rau cov khoom lag luam uas xav tau electroplating, phab ntsa tuab Lub thickness yuav tsum yog tuab me ntsis txhawm rau txhawm rau txhim kho cov nplaum rau saum npoo ntawm cov khoom. Yog li, phab ntsa tuab ntawm cov khoom yuav tsum raug xaiv ntawm 1.5 thiab 4.5 hli.

Thaum txiav txim siab cov tuab tuab ntawm cov khoom, koj yuav tsum tau them sai sai rau qhov tsis sib xws ntawm phab ntsa tuab. Tsis txhob sib txawv ntau. Cov nplaim ntawm cov khoom lag luam uas yuav tsum tau siv hluav taws xob yuav tsum ua kom du thiab tsis muaj qhov tsis sib xws, vim tias cov khoom no yooj yim rau ua raws li cov hmoov av thiab nyuaj rau tshem tawm vim hluav taws xob zoo li qub. Qhov nrawm ntawm txheej txheej zuj zus. Ib qho ntxiv, kev muaj lub kaum ntse ntse yuav tsum raug zam kom tiv thaiv kev ntxhov siab. Yog li, nws raug nquahu kom siv arcs rau kev hloov pauv ntawm cov ces kaum thiab tuab thiab nyias pob qij txha.

2. Demoulding kaum

Cov pwm tso tawm txoj kab nqes ntawm cov khoom yog cuam tshuam ncaj qha rau nws tus nqi qis. Vim yog qib sib txawv, cov khoom sib txawv sib txawv thiab cov txheej txheem sib txawv, cov txheej txheem shrinkage muaj qhov sib txawv, feem ntau 0.3 ~ 0.6%, qee zaum nce txog 0.4 ~ 0.8%, Yog li nws cov khoom muaj qhov siab molding qhov tseeb. Demolding nqes hav ntawm ABS cov khoom lag luam tau txiav txim siab raws li hauv qab no: qhov tseem ceeb yog 31 ° raws txoj kev demolding, thiab kab noj hniav ib feem yog coj 4 (/-1 ° 20' raws txoj kev demolding. cov duab lossis nrog cov tsiaj ntawv thiab cov qauv Rau cov khoom lag luam, lub kaum sab xis yuav tsum tau nce kom haum.

3. Yuav tsum tau muab tshem tawm

Vim tias qhov pom tseeb ntawm cov khoom muaj kev cuam tshuam loj rau kev ua haujlwm electroplating, ib qho me me khawb ntawm qhov saum npoo yuav pom meej tom qab electroplating. Yog li ntawd, ntxiv rau qhov tsis xav tau khawb ntawm cov kab noj hniav pwm, tseem yuav tsum tau tshem tawm. Thaj chaw muaj txiaj ntsig yuav tsum loj, kev sib koom ua ke ntawm txoj kev tshem tawm nrog ntau tus ejector pins yuav tsum yog qhov zoo, thiab lub zog tshem tawm yuav tsum zoo ib yam.

4. Tso pa tawm

Txhawm rau tiv thaiv qhov tshwm sim tsis zoo thaum lub sijhawm ua cov txheej txheem, ua rau hlawv kub hnyiab, pom meej cov kab thiab lwm yam teeb meem, nws yuav tsum tau qhib lub qhov cua lossis qhov cua qhov zawj nrog qhov tob tsis ntau tshaj 0.04 hli los pab txhawb kev tsim khoom lub yaj. Cov pa tawm.

5. Cov neeg khiav thiab lub rooj vag

Txhawm rau ua kom ABS yaj tag nrho txhua qhov ntawm kab noj hniav kom sai li sai tau, txoj kab uas hla ntawm tus khiav yuav tsum tsis pub tsawg dua 5 hli, lub tuab ntawm lub rooj vag ntau dua 30% ntawm cov khoom tuab, thiab qhov ntev ntawm qhov ncaj (hais txog ntu uas yuav nkag mus rau kab noj hniav) yog hais txog Nws yog li 1 hli. Qhov chaw ntawm lub qhov rooj yuav tsum txiav txim siab raws li qhov yuav tsum tau ua ntawm cov khoom lag luam thiab cov lus qhia ntawm cov khoom ntws. Rau cov khoom lag luam uas yuav tsum tau electroplated, feem ntau nws tsis raug tso cai kom muaj nyob rau ntawm cov nplaim nplaum ntawm txheej.
