Molemo oa Metal Surface Finishing Process
Mesebetsi ea phekolo ea holim'a tšepe e ka akaretsoa ka tsela e latelang:
● Ntlafatsa ponahalo
● Eketsa mebala e metle ka ho khetheha
● Fetola khanya
● Ntlafatsa khanyetso ea lik'hemik'hale
● Eketsa khanyetso ea ho apara
● Fokotsa liphello tsa ho bola
● Fokotsa likhohlano
● Tlosa mefokolo e ka holimo
● Ho hloekisa likarolo
● Sebeletsa e le seaparo sa pele
● Fetola boholo
Kachi, sehlopha sa rona sa litsebi sa litsebi se tla eletsa ka mekhoa e metle ea phekolo ea holim'a metsi le mekhoa ea ho qeta ho finyella liphello tsa hau tse lakatsehang. U ka khetha qetello e ntle ka ho fetisisa e matlafatsang le ho sireletsa ponahalo ea likarolo tse entsoeng ka mochine.Mekhoa e teng ea kalafo ea holim'a metsi e kenyelletsa tse latelang:
Anodize
Anodize ke ts'ebetso ea electrolytic passivation e holisang lesela la oxide ea tlhaho likarolong tsa aluminium bakeng sa ts'ireletso khahlanong le ho senyeha le ho bola, hammoho le litlamorao tsa litlolo.
Ho phatloha ha Bead
Ho phatloha ha mecha ea litaba ho sebelisa jete e hatelletsoeng ea mecha ea phatlalatso ea abrasive ho kenya matte, seaparo se tšoanang holim'a likarolo.
Electroplating
Nickel plating ke mokhoa o sebelisetsoang ho electroplate lesela le tšesaane la nickel holim'a karolo ea tšepe.Plating ena e ka sebelisoa bakeng sa kutu le ho hanyetsa ho roala, hammoho le merero ea ho khabisa.
Ho benya
Likarolo tsa mochini oa CNC tse tloahelehileng li bentšoa ka letsoho ka mahlakoreng a mangata.Bokaholimo bo boreleli ebile boa khantša hanyane.
Chromate
Kalafo ea chromate e sebelisa motsoako oa chromium sebakeng sa tšepe, e leng se fanang ka tšepe ea ho qetela e thibelang ho bola.Mofuta ona oa ho qeta holimo o ka boela oa fa tšepe ponahalo ea mokhabiso, 'me ke motheo o atlehang oa mefuta e mengata ea pente.Hase feela hoo, empa hape e lumella tšepe ho boloka motlakase oa eona oa motlakase.
Ho penta
Ho penta ho kenyelletsa ho fafatsa lera la pente holim'a karolo eo.Mebala e ka tsamaellana le nomoro ea 'mala oa Pantone eo moreki a e khethang, ha lipheletso li fapana ho tloha ho matte ho isa ho gloss ho isa ho metallic.
Black oxide
Black oxide ke seaparo sa phetoho se tšoanang le Alodine se sebelisetsoang tšepe le tšepe e sa hloekang.E sebelisoa haholo-holo bakeng sa ponahalo le bakeng sa khanyetso e fokolang ea kutu.
Ho tšoaea karolo
Ho tšoaea karolo ke mokhoa o sa jeng chelete e ngata oa ho kenya li-logo kapa litlhaku tse tloahelehileng ho meralo ea hau, 'me hangata e sebelisoa bakeng sa ho tšoaea karolo e ikhethileng nakong ea tlhahiso e felletseng.
