Ko te maitai ehara i te mea mo te wai tuku me te paura totoka, te whakawhiti wera, te hanga i nga waahanga miihini me nga ipu, he maitai ohaoha.Hangahanga whare me te apaipa maitai matiti whakangao, poupou me te tautoko miihini, ka taea te whakaiti i te taumaha me te penapena i te 20 ki te 40% whakarewa, ka taea te whakatutuki i te wheketere hanga miihini.

Te mahi whakaputa putorino maitai
Billet – Piki pire – whangai pire – wero – wero – maitai poi whawha – putorino wai pakaru – tihorenga rino – tira maitai – tiki maitai – phosphating maitai – Saponification maitai – maitai tohia matao – maitai tohia matao – Te upoko maitai – maitai oti te whakatika – tapahi rino mahunga tapatapahi hiku – maitai oti te tirotiro – ki roto i te paipa kua oti.

Ko te tirotiro ngongo totoka me te tango i nga hapa o te mata ka tapahia kia rite ki te roa e hiahiatia ana, ka mutu ki te mutunga i roto i te ngongo kua kowaowao, ka tukuna ki te whakamahana oumu, ka werohia he poka i te wa e huri haere tonu ana me te neke whakamua, me te upoko o te pukapuka i raro i te pānga o āta hanga i roto i te kōhao ngongo, ka mea ngongo capillary, a ka tonoa ki te mīhini okeoke aunoa ki te okeoke whakamutunga e rua mihini he taiepa katoa, te mira rahi te rahi, ki ngā whakaritenga, te whakamahi o te hanga mira putorino tonu. o te putorino maitai tuitui wera he huarahi matatau ake ki te whakatakoto kia iti ake, kia pai ake te kounga o te paipa, me whakamatao, me whakamatao ranei te tikanga ka hurihia i runga i te mira e rua-rora, paipa i roto i nga mokamoka o te waahanga rereke me te mahunga. e kore e neke i te poka porohita i hanga i roto i te okeoke, tuhi te tikanga i roto i te mekameka kotahi ranei mekameka rua mīhini tātuhi, tikanga extrusion e pā ana ki ngongo pai whakanohoia i roto i te whakawera kati te tokotoko extruded me te poka puoto tahi me te nekehanga tokotoko extruded, te mema pehi i te kohao iti i roto i te extrusion mate, tenei tikanga e taea te whakaputa i te putorino diameter iti.
