Hauv kev sib piv rau cov ntaub ntawv hlau, sib txawv txawv txav txawv txav, daim ntawv thiab qhov chaw feem ntau yuav tsum tau thaum ua ntawv thov thiab ua cov khoom siv cov khoom siv. Raws li cov khoom tshwj xeeb ntawm cov plastics (piv txwv li siab deformity (eg siab heev, qhov tsis tshua muaj zog), qhov ua haujlwm qis dua rau cov khoom lag luam me me kom haum.
Cov khoom ntiag tug yog txawv dua ntawm cov hlau uas tiv rau tus qauv tshwj xeeb ntawm cov plastics thiab lawv cov ntaub ntawv hloov kho. Cov yam ntxwv ntawm cov plastics cuam tshuam rau qhov raug ntawm cov ntawv sau ua ke (kev tshuaj xyuas cov khoom siv pwm, ntau dua ntawm cov duab geometrical hauv cov khoom siv hlau. Cov qauv zam tau siv rau cov khoom hlau yog li tsis muaj peev xwm los yuav tau rau cov qauv yas, lossis tsuas yog ua tau li ntawd. Qhov no ua rau cov qauv no tsim nyog rau kev tsim kev ua kom muaj kev tsim txiaj rau kev hwm cov khoom yas mould.
Cov khoom tshwj xeeb tshaj plaws ntawm cov yas txhais tau tias peb qhov sib txawv ntawm cov qib thiab cov yam ntxwv hauv kev hwm rau cov yam ntxwv tseem ceeb tau raug coj los txiav txim siab.
Tus phab ntsa
Cov txheej txheem no tau npaj los ntawm Pawg Neeg Ua Haujlwm na 054-05-13 Aa "Daj rau Plastics Cov Txheej Txheem Mouldic" ntawm Pawg Neeg Saib Xyuas Plastics (FNK).
Cov lus German ntawm lub DIN 16742 yuav tau coj raws li kev sau npe. Tsis tau lav tias tuaj yeem muab nrog hwm txhais lus Askiv. Ib qho kev ua lag luam yog siv los ua cov cim ntsuas zauv. Saib xyuas yog kos rau qhov ua tau tias qee cov ntsiab lus ntawm cov ntaub ntawv no tej zaum yuav yog qhov kev kawm patent.
Din [thiab / los yog thuam tias] yuav tsis muaj lub luag haujlwm rau kev txheeb xyuas ib qho lossis txhua qhov kev cai siv duab.
Cov Hloov Dua
Cov kev hloov hauv qab no tau ua rau muaj kev hwm DIN DIN 16901: {1}}} rho tawm hauv 2009-10:
A) tsim kom muaj kev sib xyaw ua ke nrog kev kam ua thoob ntiaj teb thiab haum rau ISO 1, iso {}, iso 80415, iso 10135, Iso 14253-1, iso 14405-1}, iso {{} 17450-2;
b) Hloov ntawm cov ntawv tso pa molding kom tau txais cov hloov tshiab tsis tu ncua los ntawm hom haujlwm raws li cov khoom ntiag tug;
c) classification of the mobilised production expense (process stability, quality assurance) for the required accuracy level from a realistic analysis of the capacity of the moulded part manufacturer in tolerances series (expense series).

Cov laj thawj hauv qab no yuav tsum tau ua raws li kev sib koom tes sib koom tes ntawm kev txhim kho kev sib koom tes ntawm kev txhim kho ib feem ntawm kev txhim kho kev sib koom tes thiab cov cuab yeej tsim:
A) Cov neeg tsim qauv ntawm cov neeg tsim qauv txiav txim siab txog kev ua haujlwm tsim nyog tau txais los ntawm cov ntawv thov thiab cov rooj sib txoos nrog kev txiav txim siab ntawm cov khoom siv pwm.
b) Cov pwm ntawm cov pwm ua kom pom tseeb, rau kev ua raws li kev sib txheeb "ua haujlwm tau ua haujlwmNtau dua los yog sib npaugKev zam kev siv thev naus laus zis ", lub thev naus laus zis ua tau nrog kev tsim thev naus laus zis ntawm cov neeg siv khoom mouldorated) tej zaum yuav tsum tau ua kom muaj kev zam txim siab yuav tsum tau ua kom muaj kev zam txim Cov. Nyob rau hauv txoj kev no, absurdly raug thiab tsis zoo li kev ntshai thiab kev ua phem rau kev ua siab ntev "yog zam.
c) Cov khoom siv ntawm cov pwm ntu yog bindingly txhais los ntawm cov neeg tsim qauv ntawm kev txiav txim siab rau thaum qhov kev txiav txim. Nws yog li ntawd tsim lub hauv paus rau kev txiav txim siab moulding shrinkage. Tom qab kev txiav txim tso chaw, suav cov nqi nyob rau hauv kev hwm ntawm Moulding Shrinkage yuav tsum tau pom zoo ntawm Moulding Part Chaw tsim tshuaj paus thiab cov cuab yeej sab nraud (piv txwv li cov khoom lag luam moulded
Nyob ntawm cov pwm ntawm cov pwm sib xyaw ua ke, pwm feem tsim qauv thiab cov cuab yeej ntawm cov yas muaj qhov cuam tshuam tseem ceeb ntawm cov khoom siv hluav taws xob. Kev ua cov tshuab ntawm thawj txoj kev ua yeeb yam yog cov tshuab ua haujlwm yooj yim ntawm cov tshuab hluav taws xob, uas yog qhov ua tiav thiab ua kom pom tseeb txawm tsim cov thev naus laus zis ntau heev.
Cov teeb meem ntawm cov plastics ntawm cov plastics suav nrog cov hom huab cua ntau heev los yog hardness nrog rau molding shrinkage. Tsis ruaj khov thiab inhomogeneous cuab yeej thiab molding cov kev sib txuas nrog cov kev sib tw nrog cov khoom ntiag tug, uas ua rau muaj kev cuam tshuam nrog cov khoom ntiag tug thiab kev tawm tsam ntau dua los ntawm cov khoom siv. Tsis tas li ntawd, cov phab ntsa tuab sib txawv lossis cov kev ua kom muaj zog / cov khoom siv ntau tuaj yeem ua rau muaj kev cuam tshuam rau deformation. Daim ntawv, qhov chaw nyob thiab lub kaum sab xis ua yog li txuas rau hauv txoj kev nyuaj, uas ua rau muaj kev nyuaj ntau hauv kev sib piv rau cov hlau.
Kev nkag tsis tau cov txheej txheem-ua rau muaj kev sib txawv yog vim li ntawd yuav tsum tau xav tias yuav tau rau cov pwm. Cov txheej txheem yuav tsum tau ua raws li kev sib txawv ntawm kev sib txawv yog nyob ntawm txoj haujlwm ntawm cov pwm thiab yog qhov yuav tsum muaj kev pom zoo:
Tshem tawm kev sib txawv los ntawm kev tsim qauv (ntxiv dag zog Ribs, cov khoom siv thickening, daim ntawv pauv thiab lwm yam);
kho qhov sib txawv los ntawm kev khaws cia hauv lub cuab tam;
khaws kev sib cav thiab cov ntaub ntawv nws los ntawm kev pom zoo kev pom zoo los sis kev kho kom haum;
Tso rau kev sib cav thiab cov ntaub ntawv los ntawm "kev sib txawv ntau dua".
Kev cim cov txheej txheem-tsim kev txawv txav tuaj yeem txo ob qho los ntawm kev tsim qauv zoo ntawm cov khoom siv pwm thiab los ntawm kev ua haujlwm ntawm cov txheej txheem ntau lawm.
