Cov ntaub ntawv khawm yog roughly muab faib ua cov yas (resin, yas), hlau nyees khawm (tooj liab, hlau, hlau), ntuj (plhaub, ntoo, txiv maj phaub plhaub, xyoob). Ntau yam khoom siv los ua cov nyees khawm, thiab cov txheej txheem sib txawv. Qee cov nyees khawm saib zoo ib yam, thiab txawm tias cov neeg hauv kev lag luam yuav tsis tuaj yeem paub qhov txawv ntawm lawv qhov muag kom pom tseeb, yog li lawv tsuas tuaj yeem paub qhov txawv ntawm khawb lub tsho loj.
Cov nyees khawm tau muab faib ua cov nyees khawm yas thiab cov nyees khawm, cov nyees khawm yas thiab cov nyees khawm resin. Yas (nrog rau ntau yam yas) nyees khawm feem ntau tuag-casted, yog li yuav muaj ib txoj kab ntawm ntug khawm. Txoj kab sib faib no, qee lub tsev tsim khoom yuav ua raws li- ua tiav. Cov xov no tau raug tshem tawm, tab sis nws qhov hnyav yuav sib zog dua li cov resin (ntawm chav kawm qee cov yas tshwj xeeb yuav hnyav dua). Resin nyees khawm yog mechanically engraved thiab tom qab ntawd polished, yog li qhov saum npoo tsis muaj kab tag nrho thiab yog du heev. Tab sis nws yog qhov tsis yooj yim, qhov saum npoo yog khawb tau yooj yim, thiab nws ua mos thaum muab tso rau hauv dej npau npau.
Yuav ua li cas paub qhov txawv ntawm cov nyees khawm tooj liab thiab cov nyees khawm hlau? : Cov nyees khawm ua los ntawm cov khoom siv tooj liab thiab hlau, koj tuaj yeem siv cov hlau nplaum kom paub qhov no, thiab txhuam cov txheej plating txheej nrog cov khoom tawv, cov xim tooj dag (kub) hauv cov pob tooj liab. Cov hlau buckle yog xim dub, uas yog xim ntawm cov khoom siv raw.
How to judge whether it is an alloy button? : The alloy buckle is relatively heavy and is made of die casting. All mold lines are generally ground and polished, so you may not see it, but it is heavy and solid.
