Choyamba, preheating:
1. Kwa chogwirira ntchito chokhala ndi mawonekedwe ovuta kapena kusintha kwakuthwa kwa gawo limodzi ndi makulidwe akulu akulu, ziyenera kutenthedwa.
2. Njira ya preheating ndi: preheating kwa 800 ℃, yachiwiri preheating ndi 500 ~ 550 ℃ ndi 850 ℃, kutentha kukwera mlingo wa preheating pulayimale ayenera kukhala ochepa.
Awiri, kutentha:
1. Pali notches ndi mabowo mu workpiece, kuponyera ndi kuwotcherera mbali ndi kukonzedwa zosapanga dzimbiri workpiece, kawirikawiri osati mu ng'anjo yosambira mchere mchere
2. Onetsetsani kuti workpiece ndi kutentha kwa nthawi yokwanira. Werengetsani makulidwe abwino a chogwirira ntchito ndi makulidwe ovomerezeka ( makulidwe enieni ochulukitsidwa ndi mawonekedwe a mawonekedwe a workpiece) potengera Table 5-16 ndi Table 5-17
Chachitatu, kuyeretsa:
1. Chogwirira ntchito ndi zida ziyenera kuchotsedwa mafuta, mchere wotsalira, utoto ndi zinthu zina zakunja musanayambe kutentha.
2. Zomwe zimagwiritsidwa ntchito kwa nthawi yoyamba mu ng'anjo ya vacuum ziyenera kuchotsedwa ndi kuyeretsedwa pasadakhale pansi pa digiri ya vacuum yofunidwa ndi workpiece.
Chachinayi, kuyatsa ng'anjo:
1. Pochiza kutentha, ntchito yowonongeka iyenera kutenthedwa pazitsulo zapadera
2. Chogwiritsira ntchito chiyenera kuikidwa pamalo otenthetsera bwino
