Dab tsi yog theem nrab ua rau txhaj tshuaj molded qhov chaw?
Kev ua haujlwm thib ob
Kev ua haujlwm thib ob ntawm cov khoom yas yog hais txog kev ua haujlwm ntxiv ntawm cov khoom tom qab kev ua haujlwm thawj zaug (kev txhaj tshuaj molding, extrusion, tuag casting). Kev ua haujlwm thib ob feem ntau suav nrog kev kho kom zoo nkauj saum npoo, machining, thiab sib dhos. Cov txheej txheem kho kom zoo nkauj saum npoo muaj xws li kev tshuaj ntsuam luam ntawv, ncoo luam ntawv, kub stamping, hloov luam ntawv kub, dej hloov luam ntawv, decals, txau, electroplating, nqus metallization, flocking, thiab ntaub qhwv. Machining txoj kev muaj xws li drilling, tig, milling, dabtsi yog khoov, thiab dov. Cov txheej txheem sib dhos feem ntau suav nrog kub yaj vuam, ultrasonic vuam, thiab laser vuam. Kev ua haujlwm thib ob ntawm cov khoom yas tuaj yeem ua rau lawv cov nqi ntxiv, ua rau lawv zoo li vibrant, thiab tsim cov khoom uas tsis tuaj yeem tsim los ntawm kev ua thawj zaug. Cov hauv qab no yog kev taw qhia txog cov txheej txheem tseem ceeb ntawm kev ua haujlwm thib ob ntawm cov khoom yas.
Silkscreen luam ntawv ntawm kev txhaj tshuaj molded qhov chaw
Screen printing yog luv luv rau "silk screen printing." Kev tshuaj ntsuam luam ntawv suav nrog kev ncab cov kab xev, hluavtaws fiber ntau, lossis hlau mesh mus rau ib lub thav duab thiab tsim lub npov luam ntawv phaj siv phau ntawv etching lossis photochemical txoj kev. Niaj hnub nimno tshuaj ntsuam luam ntawv thev naus laus zis siv cov ntaub ntawv photosensitive los tsim lub vijtsam luam ntawv phaj los ntawm txoj kev yees duab (ua rau lub mesh qhib rau hauv cov duab thaj chaw qhib thaum lub qhov qhib hauv qhov tsis yog - cov duab duab raug thaiv). Thaum lub sij hawm luam ntawv, tus cwj mem raug yuam los ntawm lub mesh qhib ntawm cov duab thaj chaw mus rau lub substrate los ntawm ib tug squeegee, tsim ib tug duab zoo tib yam rau tus thawj (saib daim duab 8-1). Cov khoom siv tshuaj ntsuam luam ntawv yog qhov yooj yim, yooj yim rau kev khiav lag luam, thiab cov txheej txheem luam ntawv thiab phaj ua tau yooj yim, pheej yig, thiab hloov tau yooj yim. Kev tshuaj ntsuam luam ntawv muaj ntau yam kev siv, feem ntau yog siv rau cov ntaub ntawv luam tawm xws li cov xim pleev xim, cov ntawv tshaj tawm, daim npav lag luam, phau ntawv npog, cov ntawv sau khoom, thiab cov ntawv luam tawm.
Pad luam ntawv ntawm kev txhaj tshuaj molded qhov chaw
Pad printing siv cov qauv ntawm gravure printing. Cov cuab yeej muaj xws li silicone ncoo, ib tug qauv luam ntawv phaj (steel los yog fiber), thiab number case. Nws tuaj yeem luam ntau cov kab zoo, fonts, thiab cov qauv, txawm tias plaub - xim ib nrab cov duab. Cov txiaj ntsig zoo tshaj plaws tuaj yeem ua tiav txawm tias qhov chaw ntawm cov khoom luam tawm yog concave, convex, lossis tsis xwm yeem.
Kub stamping ntawm kev txhaj tshuaj molded qhov chaw
Kub stamping yog ib txoj kev luam ntawv uas hloov cov qauv ntawm tus cab kuj mus rau ib qho chaw ua haujlwm hauv qab cua sov thiab siab. Nws yog ib qho tseem ceeb ntawm kev kho kom zoo nkauj saum npoo rau cov khoom yas thiab cov txheej txheem kho kom zoo nkauj siv hauv cov khoom siv hauv tsev thiab cov khoom siv hluav taws xob. Kub stamping yog muab faib ua cov menyuam stamping thiab kub stamping. Plaub yam uas yuav tsum tau muaj rau kub stamping yog: ib tug stamping tuag, ib tug stamping zaj duab xis, lub rhaub, thiab lub siab kis mechanism.
Dej hloov luam ntawv ntawm kev txhaj tshuaj molded qhov chaw
Dej hloov luam ntawv yog cov txheej txheem luam ntawv uas siv dej siab los hydrolyze cov polymers ntawm cov ntawv hloov pauv / yas zaj duab xis nrog cov qauv xim. Nws tau tsim los daws cov teeb meem ntawm cov duab nyuaj thiab nyuaj - mus rau - mus txog thaj chaw uas cov kev luam ntawv ib txwm muaj, xws li kub stamping, pad printing, thiab screen printing, tsis tuaj yeem kov yeej.
Ultrasonic vuam ntawm txhaj molded qhov chaw
Lub hauv paus ntsiab lus ntawm ultrasonic yas vuam yog tias lub tshuab hluav taws xob tsim tawm 20kHz (los yog 15kHz) siab -voltage, siab-frequency signal, uas yog hloov mus rau siab - zaus mechanical vibration los ntawm lub transducer system. Qhov kev vibration no yog siv rau cov yas ua haujlwm, thiab qhov kub ntawm qhov sib cuam tshuam nce vim kev sib txhuam ntawm qhov chaw ua haujlwm thiab cov molecules. Thaum qhov kub nce mus txog qhov melting point ntawm lub workpiece, lub interface melts sai heev thiab nyob rau hauv lub qhov khoob ntawm cov pob qij txha. Thaum lub vibration nres, lub workpiece txias thiab solidifies nyob rau hauv ib tug tej yam siab, yog li ua tau ib tug siab - weld zoo, raws li qhia nyob rau hauv daim duab 8-8. Daim duab 8-9 qhia tau hais tias lub tshuab ultrasonic vuam.
Txhaj molded qhov chaw txau
Kev txhaj tshuaj molding txheej yuav tsum tau txau ib txheej ntawm cov xim (feem ntau hu ua roj pleev xim) rau ntawm cov yas kom ua tiav cov txiaj ntsig xav tau. Cua txau yog tam sim no ib tug dav siv txheej txheej hauv painting. Cua txau siv compressed airflow, tsim tsis zoo siab los ntawm lub nozzle ntawm ib rab phom. Qhov tsis zoo siab no rub cov xim hauv los ntawm lub raj nqus dej thiab tawm los ntawm lub nozzle, tsim cov xim pos huab. Cov xim pos huab ua ib daim duab xim zoo nkauj rau ntawm qhov chaw uas tau coated. Cua txau tuaj yeem tsim cov xim pleev xim zoo ib yam nrog kev ua kom zoo nkauj thiab zoo nkauj; Nws tuaj yeem sib npaug sib npaug ntawm qhov tsis tshua pom ntawm qhov chaw (xws li crevices thiab qhov tsis sib xws). Txawm li cas los xij, txoj kev no muaj kev siv cov xim tsis tshua muaj: 50% -60%.
Electroplatingntawm cov khoom yas
Kev Taw Qhia rau Electroplating ntawm Cov Khoom Siv Yas Cov Plastics Feem ntau suav nrog cov thermoplastics thiab thermosetting plastics, ob qho tib si tuaj yeem ua tau electroplated, tab sis yuav tsum muaj kev sib txawv ua kom muaj zog, ua rau muaj qhov sib txawv tseem ceeb hauv qhov kawg ntawm qhov zoo.
Electroplating yog txheej txheem ntawm kev tso cov hlau los yog hlau rau ntawm qhov chaw ntawm lub workpiece siv electrolysis los ua ib qho kev sib xws, ntom ntom, thiab zoo- khi hlau txheej. Electroplating ntawm cov khoom yas muaj cov kev siv hauv qab no:
① Kev tiv thaiv corrosion;
② Kev tiv thaiv kho kom zoo nkauj;
③ Hnav tsis kam;
④ Cov khoom siv hluav taws xob: Muab cov khoom siv hluav taws xob lossis cov txheej txheem insulating raws li qhov yuav tsum tau ua ntawm qhov ua haujlwm.
Nqus txheej
Lub tshuab nqus tsev vacuum yog npaj cov yeeb yaj kiab hauv lub tshuab nqus tsev, suav nrog tso cov hlau crystalline, semiconductors, insulators, thiab lwm yam khoom siv los yog cov yeeb yaj kiab sib xyaw. Thaum cov tshuaj vapor deposition kuj siv cov tswv yim nqus xws li kev txo qis, tsis tshua muaj siab, lossis ntshav, lub tshuab nqus tsev feem ntau yog hais txog kev tso tawm ntawm cov yeeb yaj kiab nyias uas siv lub cev. Muaj peb hom ntawm lub tshuab nqus tsev vacuum: nqus evaporation deposition, nqus sputtering deposition, thiab nqus ion plating. Txhua txoj hauv kev no suav nrog kev tso ntau yam hlau thiab tsis yog- cov yeeb yaj kiab hlau rau saum npoo ntawm cov khoom yas hauv lub tshuab nqus tsev los ntawm kev distillation lossis sputtering. Txoj hauv kev no ua rau cov txheej txheej nyias nyias thiab muaj cov txiaj ntsig tseem ceeb xws li kev kub ceev thiab muaj zog adhesion, ua rau nws tsim nyog rau cov txheej txheem ua haujlwm siab dua - cov khoom kawg.
