Yas pwm tsim yog raws li cov khoom siv yas tsim, thiab cov pwm tsim thiab kev tsim khoom muaj feem xyuam nrog kev ua cov yas. Kev vam meej lossis tsis ua tiav ntawm kev ua cov yas feem ntau yog nyob ntawm qhov cuam tshuam ntawm pwm tsim thiab pwm tsim zoo. Cov txheej txheem tsim nyog yuav tsum tau txiav txim siab hauv kev tsim pwm yas yog:
1. Parting nto, uas yog qhov chaw sib cuag ntawm tus poj niam thiab txiv neej pwm thaum kaw cov pwm. Kev xaiv ntawm txoj hauj lwm thiab cov duab yog cuam tshuam los ntawm cov khoom xws li cov khoom zoo li thiab cov tsos, phab ntsa thickness, txoj kev tsim, tom qab ua technology, pwm hom thiab qauv, demolding txoj kev, thiab tshuab qauv.
2. Cov khoom tsim, xws li sliders, sloping tops, ncaj saum blocks, thiab lwm yam. Complex pwm. Kev tsim qauv ntawm cov khoom siv yog ib qho tseem ceeb heev thiab muaj feem xyuam rau lub neej pwm, kev voj voog, nqi, thiab cov khoom zoo. Yog li ntawd, nyob rau hauv lub complex core qauv tsim ntawm pwm, designers yuav tsum nrhiav ib tug ntau dua kev tsim, qhov yooj yim tshaj plaws, ruaj, thiab ntau economic kev daws teeb meem.
3. Pwm raug, piv txwv li tsis txhob adhesion, qhov tseeb qhov chaw, qhia ncej, positioning pins, thiab lwm yam. Qhov chaw qhov system muaj feem xyuam rau cov khoom zoo li, pwm zoo, thiab kev pab lub neej. Xaiv qhov chaw sib txawv rau cov qauv pwm sib txawv. Kev tswj ntawm qhov chaw qhov tseeb feem ntau yog nyob ntawm tus txheej txheem. Qhov chaw pwm sab hauv feem ntau yog tsim los ntawm cov neeg tsim qauv, nrog rau lub hom phiaj ntawm kev txiav txim siab thiab tsim kom muaj qhov tsim nyog thiab yooj yim kho txoj hauv kev.
4. Pouring system, uas yog cov khoom noj channel los ntawm kev txhaj tshuaj molding tshuab nozzle rau pwm kab noj hniav. Xws li cov neeg khiav dej num tseem ceeb, tus neeg khiav dej num thib ob, lub rooj vag, thiab cov khoom siv txias txias. Tshwj xeeb, qhov chaw ntawm lub rooj vag yuav tsum raug xaiv kom tso cai rau cov yas molten kom ntws zoo thiab sau cov kab noj hniav pwm. Thaum qhib pwm, cov khoom khiav thiab lub rooj vag txias cov khoom txuas nrog cov khoom yuav yooj yim pop tawm ntawm pwm. (tsis suav cov kub khiav pwm).
5. Yas shrinkage thiab ntau yam uas cuam tshuam rau cov khoom seem raug (pwm tsim thiab sib dhos ua yuam kev, pwm hnav, thiab lwm yam). Tsis tas li ntawd, thaum tsim compression thiab txhaj tshuaj pwm, nws tseem yuav tsum tau xav txog qhov sib txuam ntawm cov txheej txheem molding tshuab thiab cov qauv tsis. Khoos phis tawj pab tsim thev naus laus zis tau siv dav hauv kev tsim pwm yas.
