Shrinkage yuav tsum txawv raws li qhov loj ntawm cov khoom thiab lub thickness ntawm cov kua nplaum. Peb tus qauv tsim yuav muaj ntau yam. Rau cov pwm loj, feem ntau yuav tsum tau kuaj cov pwm ntawm qhov pib ntawm qhov loj me nrog cov ntaub ntawv ua ntej, thiab tom qab ntawd qhib cov pwm tom qab txiav txim qhov tseeb shrinkage tus nqi. Lub shrinkage ntawm cov pwm me me tsis txawv ntau. Kuj tseem muaj cov khoom sib txawv, thiab qhov shrinkage yuav txawv, yog li nws yuav tsum tau txiav txim siab ua ntej qhib pwm.
Hauv kuv lub tswv yim, ABS, PC, ABS ntxiv rau PC, thiab AS muaj qhov qis me me, tab sis nws txawv heev rau cov khoom siv tshiab los yog siv dua tshiab nrog qhov loj me xws li PP, PA, thiab PVC.

Qhov saum toj no shrinkage tus nqi tau txais tom qab ntau xyoo ntawm kev xyaum, thiab nws yog kiag li txhim khu kev qha thaum lub nruab nrab kua nplaum thickness ntawm cov khoom tsis ntau tshaj 300mm thiab tsis tshaj 3MM. Yog hais tias qhov loj ntawm cov khoom ntau tshaj 300mm, lub subtotal yog 0.0005. Yog tias qhov loj ntawm cov khoom sib txawv dhau lawm, X-axis, Y-axis, thiab Z-axis yuav tsum tau xam cais. Thaum cov kua nplaum nruab nrab ntawm cov khoom yog tuab heev, nyias nyias (hauv qab 0.5) thiab cov khoom siv tshwj xeeb rau qhov loj me.
Tsis tas li ntawd, qhov tseeb pwm shrinkage tus nqi sib txawv heev rau cov khoom sib txawv ntawm tib lub yas! Cov hauv qab no yog cov ntsiab lus ntawm qhov shrinkage tus nqi sau los ntawm tus kws tshaj lij engineers raws li xyoo ntawm kev ua tau zoo. Cia peb saib ze dua ~
