dziwitsani
Kuponya zitsulo zamtengo wapatali ndi luso lakale, lomwe linayamba zaka mazana ambiri. Kuchokera pakupanga zodzikongoletsera zovuta mpaka kupanga ziboliboli zokongoletsedwa, njira yopangirayi imalola amisiri kusandutsa zida kukhala zojambulajambula zodabwitsa. Mu bukhuli, tifufuza za makina ndi njira zomwe zimagwiritsidwa ntchito popanga zitsulo zamtengo wapatali, zomwe zikupereka chithunzithunzi chokwanira cha luso lochititsa chidwili.

Phunzirani za njira yopangira zitsulo zamtengo wapatali
Tisanafufuze makina enieni omwe amagwiritsidwa ntchito poponya zitsulo zamtengo wapatali, m'pofunika kumvetsetsa ndondomeko yonseyi. Kuponya kumaphatikizapo kusungunula zitsulo, kuzitsanulira mu nkhungu, ndiyeno kuzilola kuti zizizizira ndi kulimba. Njirayi imatha kupanga mawonekedwe ovuta komanso mapangidwe omwe angakhale ovuta kapena osatheka kukwaniritsa kudzera munjira zina.

Makina opangira zitsulo zamtengo wapatali
1. Ng'anjo yamoto
Imodzi mwa makina ofunika kwambiri omwe amagwiritsidwa ntchito poponya zitsulo zamtengo wapatali ndi ng'anjo yowotcha. Ng'anjo yamtunduwu imapangidwa kuti ifike kutentha kwambiri kuti isungunuke zitsulo monga golide, siliva, ndi platinamu poponyera. Ng'anjo zowotchera zimabwera mosiyanasiyana, kuchokera kumitundu yaying'ono yam'mwamba yomwe imagwiritsidwa ntchito popanga zodzikongoletsera mpaka kumafakitale akuluakulu omwe amagwiritsidwa ntchito popanga zambiri.

2. Centrifugal kuponyera makina
Makina opangira ma centrifugalNthawi zambiri amagwiritsidwa ntchito popanga zing'onozing'ono, zovuta zogwirira ntchito monga zodzikongoletsera. Makina amtunduwu amagwiritsa ntchito mphamvu ya centrifugal kugawa mofanana zitsulo zosungunuka mkati mwa nkhungu, kupanga zojambula zapamwamba zokhala ndi porosity yochepa. Makina opangira ma centrifugal amapezeka m'mitundu yonse yamanja komanso yodziwikiratu, kupereka kusinthasintha kwa amisiri ndi opanga.

3. Makina opangira jekeseni wa vacuum
Makina oponyera vacuum ndiofunikira kuti mupeze zoponya zapamwamba kwambiri, zopanda kanthu. Makinawa amagwira ntchito popanga malo ochotsa mpweya ndi mpweya kuchokera ku nkhungu asanathire zitsulo zosungunuka. Njirayi imathandiza kuthetsa matumba a mpweya ndikuonetsetsa kuti zitsulo zimadzaza nkhungu, zomwe zimapangitsa kuti pakhale kuponyedwa kolondola komanso koyenera.

4. Ng'anjo yosungunula induction
Kwa ntchito zopanga zazikulu komanso zopangira mafakitale,ng'anjo zosungunuka za inductionamagwiritsidwa ntchito kwambiri. Ng'anjozi zimagwiritsa ntchito ma elekitiromagineti induction kutenthetsa ndi kusungunula zitsulo, kupereka kuwongolera kutentha ndi kuwongolera mphamvu. Miyendo yosungunula induction imatha kusungunula zitsulo zosiyanasiyana, kuzipanga kukhala chida chosunthika choponyera zitsulo zamtengo wapatali pamlingo waukulu.

Ukadaulo woponya zitsulo zamtengo wapatali
Kuphatikiza pa makina opangira zitsulo zamtengo wapatali, amisiri ndi opanga amagwiritsa ntchito njira zosiyanasiyana kuti akwaniritse zomwe akufuna. Zina mwa njira zodziwika bwino ndi izi:

- Kutaya Sera: Njira yakaleyi imaphatikizapo kupanga chitsanzo cha sera cha chinthu chomwe mukufuna ndikuchiyika mu nkhungu. Sera imasungunuka ndikuchoka, ndikusiya chitsulo chodzaza ndi chitsulo chosungunuka kuti chipangike pomaliza.

- Kuponya Mchenga: Kuponyera mchenga ndi njira yosunthika komanso yotsika mtengo yoponyera zitsulo. Zimaphatikizapo kupanga nkhungu mwa kuphatikizira mchenga kuzungulira chitsanzocho, chomwe chimachotsedwa kuti chichoke m'bowo momwe chitsulo chimathiridwamo.

- Kuponyera Ndalama: Kumatchedwanso "kutaya sera," kuponya ndalama kumaphatikizapo kupanga sera yomwe imakutidwa ndi chipolopolo cha ceramic. Sera imasungunuka ndipo chigoba cha ceramic chimadzazidwa ndi chitsulo chosungunula kuti apange kuponya.

- Die Casting: Die casting ndi njira yabwino kwambiri yopangira zida zachitsulo zolondola kwambiri. Zimaphatikizapo kukakamiza chitsulo chosungunula kukhala nkhungu pansi pa kupanikizika kwakukulu, zomwe zimapangitsa kuti zikhale zovuta komanso zolimba.

Pomaliza
Kuponya zitsulo zamtengo wapatali ndi luso lodziwika bwino lomwe likuyenda bwino masiku ano. Pomvetsetsa makina ndi njira zopangira zitsulo zamtengo wapatali, amisiri ndi opanga amatha kupanga zidutswa zabwino kwambiri zomwe zimasonyeza kukongola ndi kusinthasintha kwa zipangizo zamtengo wapatalizi. Kaya tikupanga zodzikongoletsera zovuta kapena kupanga zida zamafakitale, luso lopanga zitsulo zamtengo wapatali likadali gawo lofunikira padziko lonse lapansi pakupanga ndi zojambulajambula.
