Tinplate chinhu chakakosha chinoshandiswa mumaindasitiri akasiyana-siyana, kunyanya mukurongedza nekugadzira. Mhando yetinplate yakakosha pakuona kana yakakodzera chinangwa chaicho. Chinyorwa chino chinoongorora zvakadzama zviratidzo zvikuru zvinotsanangura mhando yetinplate, kusanganisira huwandu hwetin plating, kuomarara, mhando yepamusoro, hunhu hwemakanika uye kuramba ngura.
Rudzi rwemhando ye tinplate runonyanya kutsanangurwa ne tin coating yayo, inova ukobvu hwe tin layer inoshandiswa pa substrate yesimbi. Iyi tin layer yakakosha sezvo inopa kudzivirira ngura uye inowedzera hupenyu hwechigadzirwa. Hunhu hwakajairika hwe tin coating hunowanzova pakati pe 2.8 ne 12 gramu pa square meter (g/m²), zvichienderana nekushandiswa kwaunoda. Kuyera tin coating, vagadziri vanowanzo shandisa nzira dzakadai se X-ray fluorescence (XRF) kana gravimetric analysis kuti ive nechokwadi chekuti tin layer inosangana nezvinodiwa kuti ishande zvakanaka.
Chimwe chinhu chakakosha pakuyera kunaka kwe tinplate igiredhi rekuomarara, iro rinoongorora kuramba kwechigadzirwa ichi pakuomarara uye pakusakara. Kuomarara kunowanzo kuyerwa uchishandisa bvunzo yekuomarara yeRockwell kana Brinell, uye mwero wakajairika unosiyana zvichienderana nekushandiswa kwacho. Semuenzaniso, tinplate inoshandiswa pakurongedza chikafu inogona kuda giredhi rekuomarara rakakwirira, uko kugara kwenguva refu kwakakosha. Kunzwisisa giredhi rekuomarara kunobatsira vagadziri kusarudza tinplate yakakodzera yezvigadzirwa zvavo, vachiona kuti zvinosangana nezvinodiwa neindasitiri uye zvinotarisirwa nevatengi.
Hunhu hwepamusoro chinhu chakakoshawo pakusarudza mhando yeplate yesimbi. Inosanganisira chitarisiko uye kurapwa kweplate yesimbi, zvichikanganisa runako uye mashandiro ayo. Zvikanganiso zvepamusoro zvakaita sekukwenya, makomba kana kuchinja ruvara zvinogona kukanganisa mashandiro echinhu chacho uye kukonzera ngura. Hunhu hwepamusoro hunowanzo ongororwa kuburikidza nekutarisa nemaziso uye bvunzo dzakajairwa, uye miganhu inogamuchirika inotsanangurwa nezvinodiwa neindasitiri. Kugadziriswa kwepamusoro hakungowedzere kutaridzika kwechigadzirwa chete, asiwo kunovandudza hunhu hwacho hwese hwemakanika uye kuramba ngura.
Hunhu hwemakanika, kusanganisira simba rekudhonza uye kureba, zviratidzo zvakakosha zvemhando ye tinplate. Hunhu uhwu hunoratidza kugona kwechigadzirwa ichi kutsungirira kushushikana uye kushanduka panguva yekugadzira uye kushandiswa kwekupedzisira. Simba rekudhonza rinoyerwa mu megapascals (MPa), uye kukosha kwakajairika kunosiyana zvichienderana negiredhi chaiyo yetinplate. Kureba kunoratidzwa sechikamu uye kunoratidza kugona kwechigadzirwa chacho kudhonza chisati chatyoka. Vagadziri vanowanzoita bvunzo dzekudhonza kuti vave nechokwadi chekuti tinplate inosangana nehunhu hwemakanika hunodiwa pakushandiswa kwayo, nokudaro vachivimbisa kuvimbika uye kuchengetedzeka.
Chekupedzisira, kuramba ngura ndiyo pfungwa huru mumhando ye tinplate. Tin layer inoshanda sechidziviriro kubva kuzvinhu zvinokonzera ngura nekuora. Kuramba ngura kunowanzo ongororwa kuburikidza nemiedzo yekukurumidzira ngura, senge bvunzo dzemunyu, dzinotevedzera mamiriro akaomarara. Mhedzisiro yacho inobatsira kuona hupenyu hwebasa re tinplate uye kukodzera kwayo kushandiswa kwakasiyana-siyana, kunyanya mukugadzira chikafu nezvinwiwa, uko kuchengetedza kunaka kwechigadzirwa kwakakosha.
Muchidimbu, mhando yesimbi yesimbi inoonekwa nezviratidzo zvakakosha, zvinosanganisira huwandu hwesimbi inoputirwa, kuomarara, kunaka kwechinhu pamusoro, hunhu hwemuchina uye kuramba ngura. Kunzwisisa zviratidzo izvi nemitengo yazvo kwakakosha kune vese vagadziri nevatengi kuona kuti simbi inoshandiswa muzvishandiso zvakasiyana-siyana inosangana nezvinodiwa pakushanda uye kuchengetedzeka. Nekutevedzera zviyero izvi zvemhando, indasitiri inogona kuvimbisa kuvimbika uye kugara kwenguva refu kwezvigadzirwa zvayo, zvichizopedzisira zvavandudza kugutsikana kwevatengi.
