Me ka hoʻohana ākea onā huahana palaki, He kiʻekiʻe a kiʻekiʻe aʻe nā koi o ka lehulehu no ke ʻano o ka maikaʻi o nā huahana plastik, no laila pono e hoʻomaikaʻi ʻia ka maikaʻi o ka poli poli ʻana o ka lua ʻilika mold e like me ia, ʻoi aku ka ʻino o ka ʻili o ke aniani a me ka ʻili kiʻekiʻe. ʻOi aku ka kiʻekiʻe o nā koi, a no laila ʻoi aku ka kiʻekiʻe o nā koi no ka polishing. ʻAʻole hoʻonui wale ka polishing i ka nani o ka mea hana, akā hoʻomaikaʻi hoʻi i ka pale ʻana i ka corrosion a me ke kūpaʻa ʻana o ka ʻili waiwai, a hiki ke hoʻomaʻamaʻa i ka hoʻoheheʻe ʻana i hope, e like me ka hoʻomaʻamaʻa ʻana i nā huahana plastic i ka demould a me ka hōʻemi ʻana i nā pōʻai hoʻoheheʻe injection. I kēia manawa, ʻo nā ʻano hana polishing maʻamau e like me kēia:
(1) Ka poni mīkini
ʻO ka polishing mechanical kahi ʻano polishing kahi e loaʻa ai ka ʻili maʻemaʻe ma o ka ʻoki ʻana a me ka deformation plastic o ka ʻili o ka mea e wehe ai i ka ʻāpana convex poli. ʻO ka mea maʻamau, hoʻohana ʻia nā ʻāpana pōhaku ʻala, nā huila huluhulu, ka pepa one, a pēlā aku. Ke hoʻohana nei i nā mea hana kōkua e like me nā turntables, hiki ke hoʻohana ʻia nā ʻano hana wili maikaʻi loa a me ka polishing no ka poʻe me nā koi o ka ʻili kiʻekiʻe. Ultra-precision wili a me ka polishing mea he kūikawā abrasive mea paahana, i kaomi ma luna o ka ili o ka workpiece e machined i loko o ka wili a me ka polishing wai i loaʻa abrasive, a rotates i kiʻekiʻe wikiwiki. Ke hoʻohana nei i kēia ʻenehana, hiki ke hoʻokō ʻia ka ʻili o Ra0.008μm, ʻo ia ka mea kiʻekiʻe loa ma waena o nā ʻano polishing like ʻole. Hoʻohana pinepine nā ʻano lens optical i kēia ʻano.
(2) Ultrasonic polishing
Hoʻokomo ʻia ka mea hana i loko o ka abrasive suspension a hoʻokomo pū ʻia i loko o ke kahua kani ultrasonic, a ʻo ka abrasive ka lepo a hoʻonani ʻia ma ka ʻili o ka mea hana e ka oscillation o ka hawewe kani ultrasonic. He liʻiliʻi ka ikaika macroscopic o ka hana kani ultrasonic, a ʻaʻole ia e hoʻololi i ka mea hana, akā paʻakikī ke hana a hoʻokomo i ka mea hana. Hiki ke hoʻohui ʻia ka mīkini kani kani me nā ʻano kemika a i ʻole electrochemical. Ma ke kumu o ka corrosion solution a me ka electrolysis, hoʻohana ʻia ka haʻalulu kani ultrasonic e hoʻoulu i ka hopena, i hoʻokaʻawale ʻia nā huahana i hoʻoheheʻe ʻia ma ka ʻili o ka mea hana, a ʻo ka corrosion a i ʻole electrolyte kokoke i ka ʻili he ʻano like; ʻO ka hopena cavitation o nā hawewe kani ultrasonic i loko o ka wai hiki ke kāohi i ke kaʻina hana corrosion, kahi kūpono i ka hoʻomālamalama ʻana o ka ʻili.
ʻ
(3) ʻO ka poli wai
Ke hilinaʻi nei ka wai polishing i ka wai kahe kahe kiʻekiʻe a me nā ʻāpana abrasive i lawe ʻia e ia e ʻoki i ka ʻili o ka mea hana e hoʻokō ai i ke kumu o ka polishing. ʻO nā ʻano hana maʻamau: ka mīkini jet abrasive, ka mīkini jet wai, hydrodynamic grinding, etc. ʻO ka hydrodynamic grinding ke alakaʻi ʻia e ke kaomi hydraulic, no laila e kahe ka wai e lawe ana i nā ʻāpana abrasive ma luna o ka ʻili o ka mea hana i ka wikiwiki kiʻekiʻe. Hana ʻia ka medium me nā mea hoʻohui kūikawā (polymer-like substance) me ka kahe maikaʻi ma lalo o ke kaomi haʻahaʻa a hui pū ʻia me nā abrasives, a hiki i nā abrasives ke silicon carbide pauka.
(4) ʻO ka wili ʻana a me ka poli ʻana
ʻO ka wili ʻana a me ka polishing magnetic ka hoʻohana ʻana i nā abrasive magnetic e hana i nā pulupulu abrasive ma lalo o ka hana a kahi kahua magnetic e wili ai i nā mea hana. Loaʻa i kēia ʻano ka hana kiʻekiʻe o ka hana, ka maikaʻi maikaʻi, ka mana maʻalahi o nā kūlana hana a me nā kūlana hana maikaʻi. Me nā abrasives kūpono, hiki i ka roughness ili ke hiki i Ra0.1μm.
ʻOkoʻa loa ka polishing i loko o ka hoʻoheheʻe ʻia ʻana o ka mold plastic mai ka polishing surface i koi ʻia i nā ʻoihana ʻē aʻe. ʻO ka'ōlelo koʻikoʻi, pono e kapaʻia ka polishing o ka mold i ka hana aniani. ʻAʻole ia wale nā koi kiʻekiʻe no ka poli ʻana iā ia iho akā nā kūlana kiʻekiʻe no ka palahalaha o ka ʻili, ka maʻalahi a me ka pololei geometric. Pono ka hoʻoliʻiliʻi ʻana i ka ʻili no ka loaʻa ʻana o kahi ʻālohilohi
Hoʻokaʻawale ʻia ka maʻamau o ka hana aniani i ʻehā mau māka: AO = Ra0.008μm, A1 = Ra0.016μm, A3 = Ra0.032μm, A4 = Ra0.063μm, he paʻakikī ke kāohi pono i ka pololei geometric o nā ʻāpana ma muli o ka electrolytic polishing. , ka wai polishing a me nā ʻano hana ʻē aʻe Akā naʻe, ʻaʻole hiki ke hoʻokō ʻia ka maikaʻi o ka ʻili o ka chemical polishing, ultrasonic polishing, magnetic grinding a me nā ʻano polishing i nā koi, no laila ke hoʻomau ʻia nei ka hoʻoili ʻana o ke aniani o nā mold precision e ka mechanical polishing.
