Cov txuj no yog siv ntsuas ntawm mus shrinkage rau txhaj tshuaj thiab compression molding. Cov ntaub ntawv rau shrinkage pwm yuav tau
siv khoom tawg yooj yim sib piv rau lwm yam. Cov pwm shrinkage qhov tseem ceeb mas yog dependant rau qhov ntsuas, lwj configuration pwm, thiab ua
cov neeg mob.
Pwm shrinkage rau cov ntaub ntawv raws kom txaus thiab transverse (los yog thoob txaus) cov kev qhia. Txaus qhia tawm raws li cov kev taw qhia cov
molten khoom tawg yooj yim yog mus tsham thaum nws nyob ntawm lub rooj vag thiab nkag mus rau hauv cov pwm.
Ntsuas Orientation
Peb mus yam tej zaum yuav tsis muab mus shrinkage pwm, cov hom A, B hom, thiab cov yam D2. Shrinkage pwm expressed raws feem pua
hloov ntawm ib tug mus in relation to qhov ntev pwm dimension.
Payment pwm shrinkage nyob rau hauv cov kev taw qhia txaus los ntawm:
SFlow = 100 * (LM - LS) / LM
qhov twg LM qhov ntev ntawm sab lus kuaj txog tus kab noj hniav pwm thiab LS coj kom txog tus ntawd mus tom qab nws tau txias.
Payment pwm shrinkage nyob rau hauv cov kev taw qhia transverse los ntawm:
STransverse = 100 * (WM - WS) / WM M yog cov dav uas xeem ntu ntawm cov kab noj hniav pwm thiab WS yog cov dav uas cov xeem mus coj
tom qab nws tau txias.
