Potengera zomwe zikuchitika m'mafakitale-makamaka kukula kwachangu kwa magawo a magalimoto ndi zida zapakhomo-zopangapanga za aluminiyamu zapita patsogolo kwambiri. Makina oponyera kufa amakhala ngati chida chofunikira kwambiri pakuponyera aluminium kufa; makinawa ali m'magulu awiri: ozizira-chipinda ndi otentha-chipinda. Ndiye, pali kusiyana kotani pakati pa njira zogwirira ntchito zamitundu iwiriyi yamakina oponya kufa?

Njira yogwiritsira ntchito chipangizochi imayenda motere: Choyamba, nkhungu imatsekedwa. Chitsulo chosungunuka chimayikidwa pamanja (kapena mwamakina) m'chipinda chowombera. Poyambirira, pamene plunger imatsika, liwiro lake la jekeseni ndilochepa; Kenako imalowa m’chipindacho n’kukhudzana ndi chitsulo chosungunula.
Plunger ikafika pamlingo wokwera-wobaya jekeseni, kuchuluka kwa zitsulo zosungunuka zomwe zili pakati pa chigawo chapansi ndi chapamwamba cha plunger chimayendetsedwa pansi pa liwiro lofanana. Mukamaliza kudzaza nkhungu, plunger imagwiritsa ntchito kukakamiza komaliza.

Njira yogwiritsira ntchito chipangizochi ndi motere: Choyamba, mbale ya makina (mutu wa mbale) imabweretsedwa mwamphamvu ndi nkhungu ya sprue bushing ndi nozzle; nkhungu ndiye yotsekedwa. Jekeseniyo akafika pamalo enaake, chitsulo chosungunula chimalowa m'chipinda cha gooseneck kudzera polowera chakumbuyo ("L-doko").
Pamene jekeseni wa jekeseni akucheperachepera ndikusunthira pansi, imatseka doko lolowera kumbuyo. Pamene plunger ibwerera (ikukwera mmwamba), imakoka chitsulo chosungunuka chomwe chili mkati mwa mphuno ndi njira ya gooseneck kubwerera ku chipinda cha gooseneck. Panthawi imeneyi, mbale ndi nkhungu za sprue bushing zimachotsedwa pamphuno.
Kutengera ndi zomwe zili pamwambazi, ndi zoonekeratu kuti makina oponyera zinthu akugwera m'magulu awiri: ozizira-chamber ndi otentha-chamber. Poyerekeza, ngakhale makina otentha{3}}achipinda nthawi zambiri amagwira ntchito bwino kwambiri, njira zoyendetsera mitundu iwiriyi zimasiyana, monganso zida ndi magawo omwe adapangidwa kuti azikonza. Popanga zinthu zenizeni, opanga akuyenera kusankha makina oyenera oponya zinthu poganizira mozama zinthu zenizeni, mtundu wake, ndi zofunikira zenizeni za aluminiyamu yakufa-zinthu zotayidwa zomwe akufuna kupanga.
