Kwa mchakato huu, manufacturers of aluminum circles are obliged to roll and calender the 6 millimeters thick billet to the required thickness of aluminum circle.
Kilicho muhimu zaidi ni kuwa na uwezo wa kudhibiti kwa uangalifu kiwango cha kusongesha na kuweka kalenda ya kila pasi..
Hata hivyo, baada ya kutekeleza tafiti za kiasi, tumegundua kila kiasi cha kuweka na kuweka kalenda hakitazidi 60%. Ili kuiweka kwa usahihi zaidi, kiwango cha juu cha kalenda ya 1.0 millimeter should be o.6mm or else it will affect the quality of aluminum circle.
Zaidi ya hayo, sahani sawa itakuwa sare calendered na akavingirisha.
Muhimu zaidi, chini ya hali ya kufanikiwa kudhibiti unene na upana wake, aluminum circle’s thickness tolerance should be controlled within plus or minus 0.01mm.
