Tuhinga o mua
Ko te tiihi makariri he mea hanga i te koti wera wera. I roto i te huringa makariri, ka hurihia te tiihi wera i raro i te pāmahana repa, a ko te kowiri tira e hurihia ana i te pāmahana rūma. Ko te pepa maitai me te ihirangi silicon teitei he iti te kaha me te iti o te kiripiri, me matua ki te 200 ° C i mua i te hurihuri makariri. Mai i te mea kaore i te mahana te maramara o te makariri i te wa o te mahinga whakaputa, kaore i te he i te oriwa me te kounga o te hau, me te kounga o te mata me te mutunga.

Ko te karaehe panini makariri
1. 195, 215, 235, 255, 275 - Ko te tohu mo te paanga o a raatau hua (rohe), te waahanga: MPA MPA (N / MP2); I runga i nga taonga miihini whanui o te kaha maitai o te Q235, he uaua me te maara i roto i te kowiri hanganga i roto i te kowiri hanganga o te waro, na reira he whanui rawa te whanui o te tono.
2.
3. Germany Load St12 - St-Steel (STELL), 12-akomanga te pepa kowiri tio.
Te tono o te kowiri tio makariri
He pai te mahi a te tiihi makariri, ara, na roto i te maeke makariri, he maamaa teitei, he maamaa te mata o te mata makariri, me te maamaa o te pepa makariri. Ko te tukatuka o te raima, te rereketanga, me nga ahuatanga o te mahi tohu nui me te iti o te whakamahinga, he nui te whakamahi i te umanga, me te hanga whare.
