Lub tshuab xuab zeb molding tsis siv neeg yuav ntsib qee qhov tsis zoo hauv cov txheej txheem siv, cov hauv qab no yog qee qhov teeb meem tshwm sim thiab cov hau kev kom tsis txhob muaj lawv:
Teeb meem porosity: porosity feem ntau tshwm sim hauv qhov chaw ntawm qhov casting, uas yog qhia ua ib qho porosity lossis honeycomb porosity nrog qhov chaw huv thiab du. Qhov no yuav tshwm sim los ntawm qhov chaw tsis tsim nyog ntawm lub kaw lus pouring, qhov kev sib sau ua ke ntawm cov pwm xuab zeb ntau dhau lossis cov pa tawm tsis zoo ntawm cov xuab zeb core. Yuav kom tsis txhob muaj qhov cua, nws yuav tsum tau ua kom ntseeg tau tias lub kaw lus pouring tau teeb tsa zoo, cov pwm xuab zeb yog sib npaug hauv qhov sib sau ua ke, cov xuab zeb core tsis muaj kev thaiv, thiab qhov cua lossis qhov cua nkag tau teeb tsa rau ntawm qhov siab dua ntawm qhov casting.
Teeb meem qhov xuab zeb: Qhov xuab zeb hais txog qhov chaw casting muaj cov xuab zeb me me. Qhov no yuav tshwm sim los ntawm kev tso tsis raug ntawm lub kaw lus nchuav, tsim tsis zoo ntawm cov qauv qauv, lossis lub sijhawm nyob ntev dhau ntawm cov pwm ntub ua ntej nchuav. Cov txheej txheem los tiv thaiv cov qhov xuab zeb suav nrog kev tsim kom zoo ntawm qhov chaw thiab qhov loj ntawm lub kaw lus casting, xaiv qhov pib nqes hav thiab lub kaum sab xis, thiab luv lub sijhawm nyob ntawm cov pwm ntub ua ntej nchuav.
Teeb meem ntawm cov xuab zeb uas muaj nyob hauv: cov xuab zeb uas muaj nyob hauv txhais tau tias muaj ib txheej xuab zeb molding nyob nruab nrab ntawm ib txheej hlau thiab qhov casting ntawm qhov chaw ntawm qhov casting. Qhov no yuav yog vim qhov pwm xuab zeb khov kho lossis kev sib zog tsis sib xws, lossis qhov chaw nchuav tsis raug thiab lwm yam laj thawj. Cov txheej txheem kom tsis txhob muaj cov xuab zeb uas muaj nyob hauv suav nrog kev tswj cov pwm xuab zeb kom nruj, txhim kho qhov cua nkag tau, thiab ntxig cov ntsia hlau rau hauv cov chaw tsis muaj zog hauv zos thaum lub sijhawm ua qauv tes.
Teeb meem ntawm lub thawv tsis raug: Lub tshuab pwm tsis siv neeg yuav muaj teeb meem ntawm lub thawv tsis raug hauv cov txheej txheem tsim khoom, cov laj thawj yuav suav nrog qhov tsis sib xws ntawm lub phaj pwm, lub koob tso lub khob hliav qab lo rau cov xuab zeb, qhov kev sib hloov sab saud thiab sab qis los ntawm kev thawb ceev dhau, phab ntsa sab hauv ntawm lub thawv tsis huv thiab lo rau cov xuab zeb, thiab qhov kev tsa tsis sib xws ntawm cov pwm ua rau lub log xuab zeb ntawm lub thawv qaij. Txhawm rau daws cov teeb meem no, nws yuav tsum tau ua kom ntseeg tau tias qhov tsim ntawm lub phaj yog qhov tsim nyog, lub koob tso lub khob hliav qab huv, qhov ceev ntawm kev thawb hom yog qhov nruab nrab, phab ntsa sab hauv ntawm lub thawv huv, thiab cov pwm yog du.
Los ntawm cov kev ntsuas saum toj no, qhov ua tau tsis zoo hauv kev siv lub tshuab xuab zeb molding tsis siv neeg tuaj yeem txo qis tau zoo, thiab qhov zoo ntawm casting tuaj yeem txhim kho.
