Uma uzwa 'i-metal faka i-plastic injection molding', isithombe esiseduze ngokuvamile siyingxenye yensimbi elula embozwe ngepulasitiki. Kodwa yilapho umbono wokuqala oyiphutha ulele khona. Akukhona nje ukubeka ucezu lwensimbi esikhunjeni bese udubula upulasitiki nxazonke. Inselele yangempela, nalapho amaphrojekthi amaningi ekhubeka, isekulawuleni ukunwetshwa kokushisa okuhlukile nokuzuza isibopho esihlala ngaphansi kwengcindezi, hhayi nje ukubukeka kukuhle kusampula. Ngibone amadizayini amaningi kakhulu ehluleka ngoba aphathe okufakiwe njengokucatshangelwa kamuva.
Inselele Eyinhloko: Umshado, Hhayi Ukuqondana
Inkinga eyisisekelo isixhumi esibonakalayo. Inkontileka yensimbi icishe ibe ngu-0.000006 in/in ngakunye °F, kuyilapho ipulasitiki evamile njengenayiloni ingase ifinyezeke ngokuphindwe kashumi kuleso silinganiso. Uma uvele udizayine okufakiwe okugoqiwe okuqondile bese ukubumba phakathi, ipulasitiki izoshwabana kuyo, impela. Kodwa ingabe izobamba ngaphansi kwamabhayisikili ashisayo? Cishe cha. Ingcindezi ingabangela ukuqhekeka noma, okubi nakakhulu, ukulahlekelwa kancane kancane kwamandla e-torque uma kuwukufaka okunentambo. Awuhlanganisi nje izinto zokwakha; ushada nokuziphatha kwabo.
Yilapho ulwazi oluvela kwezinye izinqubo luba wusizo olukhulu. Bheka inkampani efana I-Qingdao Qiangsenyuan Technology Co., Ltd.(QSY). Ngesizinda sabo seminyaka engama-30 ukutshala imali futhi CNC imishini zezinsimbi nama-alloys akhethekile, baqonda insimbi. Lolo lwazi olujulile lwezinto ezibonakalayo lubalulekile lapho ucacisa isishuthelo. Ukukhethwa kwe-alloy, ukuphela kwayo kwendawo, ngisho nomlando wayo oshisayo kusukela ekubunjweni noma ekusetshenzisweni komshini kuthinta isibopho sokugcina. Okufakiwe akuyona nje ingxenye yempahla; izindaba zayo zangaphambi kwe-conditioning.
Isibonelo, sake sasebenzisa ukufakwa kwe-stainless 304 okujwayelekile kwendlu engabona ukushintsha kwezinga lokushisa kwangaphandle. Ipulasitiki kwakuyi-PBT egcwele ingilazi. Amaqoqo okuqala aphumelele ukuhlolwa kokukhipha. Kodwa ngemva kwemijikelezo yokushisa engu-500, izindlu zaqala ukuqhekeka kuzo zonke izinto ezifakiwe. Ukwehluleka kwakungekho ekubumbeni; bekukumataniswa okubalulekile kanye nomklamo wezici zokugcina zokufaka. Kwadingeka sibuyele emuva, sishintshele endaweni efakwayo enejiyomethri enolaka, engaphansi komshini osuka ebangeni elihlukile, futhi siyishise kusengaphambili ibe nezinga lokushisa elithile ngaphambi kokulibumba. Umehluko wawubusuku nemini.
Ama-Nuances Enqubo: UDeveli ukumininingwane
Ukuzenzakalela kuzwakala kukuhle uze ubhekane nama-microscopic burrs. Esinye sezinyathelo eyisicefe kakhulu, kodwa esibucayi, ukulungiselela ukufaka nokubamba. Uma ufuna ukufakwa kumshini onembile njenge-QSY (ungabona iphothifoliyo yabo yamandla kokuthi https://www.tsingtaocnc.com), uthola izingxenye ezinokubekezelelana okungaguquki. Kodwa noma kunjalo, inqubo yokukhipha imali ayinakuxoxisana. I-burr encane ingasebenza njengesigxili sokucindezeleka, iqalise ukuqhekeka epulasitiki njengoba iphola futhi incipha.
Bese kuba khona ukubekwa. Ukulayisha mathupha kunephutha futhi kuhamba kancane. Izingalo zamarobhothi zingcono, kodwa zidinga ukulungiswa okuphelele esikhunjeni. Isikhunta ngokwaso sidinga imigodi eqondile futhi ngokuvamile sidinga ukuphathwa okushisayo-ngezinye izikhathi udinga ukushisa isikhwama sokufaka, ngezinye izikhathi udinga ukupholisa ngokushesha, kuye ngokuthi ipulasitiki. Awukho umthetho owodwa. Ngikhumbula iphrojekthi lapho kwakudingeka sisebenzise izifudumezi zendawo ezakhelwe kusikhunta ukuze silethe ukufakwa kwe-aluminium ku-120 ° C ngaphambi komjovo ukuvimbela imigqa yokushisela nokuqinisekisa ukugeleza okuzungeze izici eziyinkimbinkimbi.
Futhi flash. O, ukukhanya. Uma okufakiwe kungahlali kahle, noma uma amandla okubamba enganele, ipulasitiki izongena esikhaleni esincane kakhulu. Lokhu kudala ifleshi okunzima ngendlela emangalisayo ukulikhipha ngoba ligoqwe ngensimbi. Ngokuvamile kudinga ukusebenza komshini wesibili, okwehlula inhloso yenqubo yokuma kwenetha. Lona umbulali wezindleko ezithule ukuthi izingcaphuno eziningi aziphuthelwa ngokuphelele.
Ukukhetha Okubalulekile: I-Symphony, Hhayi I-Solo
Awukwazi ukukhuluma ngenqubo ngaphandle kokukhuluma ngepulasitiki. Kuwugibe oluvamile ukukhetha ipulasitiki yomsebenzi wengxenye eyinhloko bese uthemba ukuthi okufakiwe kuyasebenza. Kufanele kube yisinqumo esihlanganyelwe. Ama-amorphous resins afana ne-ABS noma i-PC bond ngokuhlukile kunama-semi-crystalline afana ne-POM noma i-PA. Izigcwalisi zengilazi noma zamaminerali zandisa ukuqina kodwa zehlisa ubunzima bokwehluleka, okwenza isixhumi esibonakalayo sibe nzima nakakhulu.
Yilapho ubungcweti bensimbi obuvela kozakwethu bubaluleka khona. Umsebenzi we-QSY nge esekelwe ku-cobalt futhi ama-alloys asekelwe ku-nickel ingcindezi ephezulu, izinga lokushisa eliphezulu libanika ukuqonda kwangaphakathi kokuthi izinsimbi ziziphatha kanjani ngaphansi kokuvinjelwa. Lapho befaka umshini wokufaka, bacabanga ngesakhiwo sokusanhlamvu, ingcindezi eyinsalela evela ekusikeni, nokuthi leyo ndawo izosebenzisana kanjani ne-polymer encibilikisiwe egeleza ngomfutho omkhulu. Lokho akuwona umqondo ojwayelekile wesitolo somshini jikelele.
Sasinengxenye yensiza yezokwelapha eyayidinga ukufakwa ngokuzenzakalelayo. Ipulasitiki yayiyi-PEEK enezinga eliphezulu lokushisa. Inketho yokufaka esobala kwakuyinsimbi engagqwali eyenziwe ngomshini. Kodwa ukukhanda okujwayelekile kushiye ukuhluka kwe-micro-surface okudale amaphuzu abuthakathaka. Ngokusebenza nethimba eliwuqondayo wonke umjikelezo wokuphila, sigcine sicacisa ukuthungwa kwendawo egxishwe ngokukhethekile kokufakiwe, okwabe sekudluliswa. Amandla ebhondi ngemva kwemijikelezo yokuvala inzalo ayengaphezulu kwama-40% ngaphezulu. Lokho kwavela engxoxweni yezinto ezibonakalayo ejulile, yokuhlanganyela, hhayi nje ukushintshana ngokudweba.
Uma Kungalungile: Ukufunda Ekuhlulekeni
Akuwona wonke amaphrojekthi ayimpumelelo yezincwadi. Okunye okuhlangenwe nakho okuthobisa kakhulu kwakuyindlu enkulu, enezindonga ezincane enezindonga ezingaphezu kuka-50 zokufaka izixhumi. Umklamo wawubukeka umuhle ephepheni. Sayibumba. Izingxenye zaphuma ngokubukeka ziphelele. Kodwa ngesikhathi sokuhlolwa kwe-drop, izindlu azizange ziqhekeke-ipulasitiki ezungeze ingxenye yokufakwayo ivele iyeke. Izinto ezifakiwe zaziphotha ngokukhululekile emaphaketheni azo.
Ukuhlolwa kwesidumbu kwembula izinto ezimbili. Okokuqala, izinsimbi zethusi zazinendawo ebushelelezi, ephucuziwe lapho iwa, eyayingenzi lutho olutheni ukuze ipulasitiki ibambeke ngomshini. Okwesibili, futhi ngobuqili, iphethini yokugeleza yepulasitiki yakha imigqa ye-weld ebuthakathaka ngqo ngemuva kokufaka ngakunye ngenxa yendlela okufakwayo okuphazamise ngayo ukugeleza. Isixazululo kwakungekona nje ukushintsha ukuthungwa kokufaka. Bekumele sidizayine kabusha isango nesistimu yomgijimi ukuze siqinisekise ukuthi i-flow front izohlangana ngaphambi kokuhlangana nokufakayo, hhayi eduze kwayo. Yengeza izindleko nobunkimbinkimbi esikhunjeni, kodwa kwaba ukuphela kwendlela.
Enye imodi yokwehluleka yakudala ukugqwala. Uma usebenzisa okokufaka kwensimbi okuhlukile engxenyeni engase ibone ukuswakama noma ukungcoliswa kwe-ionic, ukugqwala kwe-galvanic kungenzeka kusixhumi esibonakalayo, kwehlise isithunzi kancane kancane ibhondi. Ngikubonile lokhu kuma-automotive electronics. Ukwehluleka okuthatha izinyanga noma iminyaka ukuvela. Manje, sihlala sicabangela imvelo futhi ngezinye izikhathi sicacisa igesi ye-platin noma ama-alloys ahambisanayo, ngisho noma kubiza kakhulu ngaphambili.
Isithombe Esikhulu: Kungani Kufanele Inkinga
Pho kungani uzihlupha ngakho konke lokhu kuyinkimbinkimbi? Ngoba uma kwenziwa kahle, faka insimbi yokubumba umjovo wepulasitiki kwakha izingxenye ezingenakwenzeka nganoma iyiphi enye indlela. Uthola amandla enziwe endawo, ukuqhutshwa kwe-conductivity, noma ukumelana nokugqokwa kwensimbi kuhlanganiswe nenkululeko yokuklama, ukukhanya, kanye nokuphumelela kwezindleko zokubumba ipulasitiki. Inika amandla imihlangano edidiyelwe, inciphisa ukubalwa kwengxenye, futhi ivamise ukuqeda ukusebenza komhlangano wesibili njengokufakwa kwe-press-fitting noma ukufakwa kwe-ultrasonic.
Kuyinqubo edinga ukuhlonishwa kwazo zombili isayensi yezinto ezibonakalayo. Awukwazi nje ukuba uchwepheshe wepulasitiki noma uchwepheshe wensimbi. Udinga ukukwazi kahle kokubili, noma usebenze nozakwethu abakhona. Ifemu efana ne-QSY, ibhuloho ukubunjwa kwegobolondo amafomu ensimbi ayinkimbinkimbi futhi CNC imishini ngokunemba, iletha lokho kujula kohlangothi lwensimbi olubalulekile etafuleni. Umlando wabo omude usho ukuthi kungenzeka babone ukuthi izingxenye zabo zensimbi zihluleka kanjani emkhakheni, okwazisa umklamo wokufaka ongcono kusukela ekuqaleni.
Ekugcineni, ukubumba okuphumelelayo kokufakwa kwensimbi kumayelana nokulindela ingxoxo phakathi kwezinto ezimbili phakathi kwempilo yonke yomkhiqizo. Akuyona inqubo ehlanzekile, yasetiyetha. Kungcolile, kunamandla, futhi kugcwele izinqumo ezincane ezinemiphumela emikhulu. Kodwa ukukulungisa—yilapho ukwaneliseka kwangempela kobunjiniyela kulele khona. Ingxenye isebenza nje, buthule nangokuthembekile, futhi lokho umgomo omkhulu.
