Noj cov kab rov tav tuag casting tshuab ua piv txwv, cov khoom siv niaj hnub no tuaj yeem siv cov txheej txheem extrusion casting thiab tsim extruded tuag castings yam tsis tau ntxiv cov cuab yeej siv tshuab tshiab. Txawm li cas los xij, qhov tshwm sim tau muaj cov qauv yooj yim me ntsis, thiab qhov tseeb qhov tseeb ntawm lawv cov tuab yog qee qhov txwv.
Vim hais tias cov kab rov tav tuag casting tshuab tsis muaj qhov tshwj xeeb extrusion nyiaj mechanism, lub pwm kaw mechanism yuav tsum ua tib zoo tuav pwm kaw thiab extrusion nyiaj ua haujlwm. Lub extrusion casting pwm siv yuav tsum muaj ib lub punch uas npog tag nrho qhov projected cheeb tsam ntawm ib feem, qhov tseem ceeb ua "punch," zoo ib yam li cov pwm siv nyob rau hauv qhib extrusion casting tshuab. Qhov no yog ib txwm ua thiab raug extrusion casting pwm qauv.
Yog li ntawd, siv cov txheej txheem extrusion casting rau ib txwm kab rov tav tuag casting tshuab yuav tsum tau ceev faj tswj cov pwm kaw qhov tseeb. Txoj kev yooj yim tshaj plaws yog los tswj qhov raug pwm kaw txoj hauj lwm los ntawm li-hu ua "tiag- tswj lub sijhawm." Qhov no ua tiav los ntawm kev ntxiv "txoj haujlwm tswj" hloov mus rau lub tshuab tuag casting thiab kho lub tshuab logic Circuit Court raws li. Lub thickness raug ntawm qhov tuag casting yog txwv los ntawm kev tswj tau qhov tseeb ntawm qhov "txoj hauj lwm tswj kev hloov." Los ntawm qhov kev txhim kho no, tag nrho cov txheej txheem extrusion tuag casting yuav zoo ib yam li qhov uas twb muaj lawm ntsug kaw- pwm (punch- hom pwm) thim rov qab- txheej txheem extrusion casting.
Siv cov khoom siv kab rov tav tuag casting tshuab rau extrusion tuag casting, vim yog kaw- pwm filling txoj kev, tsis tsuas yog nws tuaj yeem tsim cov khoom nrog cov qauv nyuaj dua li cov txheej txheem ntsug extrusion casting tshuab qhib - pwm casting txoj kev, tab sis kuj, vim hais tias cov txheej txheem txhaj tshuaj yog sophisticated ntau tshaj li ntawm ib tug extrusion casting tshuab hloov dua siab tshiab }} ntau tshaj li ntawm ib tug xovxwm ntau tshaj li ntawm ib tug xovxwm 2. ntsug kaw-pwm thim rov qab-txoj kev extrusion casting txoj kev, nrog tib complexity coefficient raws li cov tsoos tuag casting txheej txheem.
