(19) Dimensional sib txawv ntawm kev txhaj tshuaj molded qhov chaw Txhaj Molding txheej txheem tsis xws luag tuav phau ntawv (65 hom)

Cov yam ntxwv ntawm qhov tsis xws luag hauv kev txhaj tshuaj molded qhov chaw
Kev hloov pauv ntawm qhov hnyav thiab qhov loj me thaum txhaj tshuaj molding ntau tshaj qhov muaj peev xwm ntawm cov pwm, txhaj tshuaj molding tshuab, thiab cov yas sib xyaw ua ke.
2. Tej yam ua rau muaj teeb meem
(1). Muab cov yas tsis sib npaug rau hauv lub tog raj kheej txhaj tshuaj.
(2) Qhov kub lossis qhov hloov pauv ntawm lub tog raj kheej txhaj tshuaj loj dhau.
(3) Lub peev xwm ntawm lub tshuab txhaj tshuaj molding yog tsawg dhau.
(4) Kev txhaj tshuaj siab tsis ruaj khov.
(5) Cov ntsia hlau rov pib dua yog tsis ruaj khov.
(6) Kev hloov pauv ntawm lub sijhawm ua haujlwm thiab cov tshuaj tsis sib haum viscosity.
(7) Kev txhaj tshuaj ceev (kwj tswj) tsis ruaj khov.
(8) Ib hom yas uas tsis haum rau pwm tau siv.
(9) Xav txog pwm kub, txhaj tshuaj, ceev, sij hawm, thiab siab tuav
Qhov cuam tshuam rau cov khoom.
3. Kev kho mob
(1) Xyuas seb puas muaj cov dej txias txaus ntws los ntawm lub caj pas hopper kom tswj tau qhov kub thiab txias.
(2) Txheeb xyuas qhov tsis zoo lossis cov thermocouples xoob.
(3) Txheeb xyuas tias cov thermocouples siv nrog lub ntsuas kub yog hom raug.
(4) Tshawb xyuas qhov txhaj tshuaj kom muaj nuj nqis thiab lub peev xwm ntawm lub tshuab txhaj tshuaj molding, thiab tom qab ntawd muab piv nrog cov tshuaj txhaj tshuaj tiag tiag thiab kev txhaj tshuaj ib teev.
Sib piv cov yas siv.
(5) Xyuas seb puas muaj cov khoom kub kub ruaj khov thaum lub sijhawm ua haujlwm.
(6) Txheeb xyuas qhov rov qab tiv thaiv valve kom xau thiab hloov nws yog tias tsim nyog.
(7) Tshawb xyuas cov khoom noj tsis raug.
(8) Xyuas kom meej tias cov ntsia hlau ruaj khov ntawm qhov chaw rov qab thaum lub sijhawm ua haujlwm, piv txwv li tsis pub ntau tshaj 0.4 hli hloov.
(9) Tshawb xyuas qhov tsis sib xws hauv lub sijhawm ua haujlwm.
(10) Siv lub zog rov qab.
(11) Tshawb xyuas seb lub tshuab hydraulic ua haujlwm li cas thiab seb cov roj kub siab dhau lossis qis dhau (25-60oC).
(12) Xaiv cov yas ntau yam uas haum rau pwm (tsuas yog xav txog shrinkage thiab txhua yam muaj zog). (13) Kho tag nrho cov txheej txheem tsim khoom.
