fakitale ya ndodo ya pulasitiki ya nayiloni ya pp pom abs

Pali mapulasitiki ambirimbiri omwe akugulitsidwa kuti agwiritsidwe ntchito mwachangu kapena kupanga zinthu zazing'ono - kusankha pulasitiki yoyenera pa ntchito inayake kungakhale kovuta, makamaka kwa opanga zinthu kapena amalonda omwe akufuna kupanga zinthu. Chilichonse chimayimira mgwirizano pankhani ya mtengo, mphamvu, kusinthasintha komanso mawonekedwe ake. Ndikofunikira kuganizira osati kugwiritsa ntchito gawo kapena chinthucho chokha, komanso malo omwe chidzagwiritsidwe ntchito.
Kawirikawiri, mapulasitiki opanga zinthu zamakono ali ndi mphamvu zabwino zamakina zomwe zimapangitsa kuti zinthu zikhale zolimba kwambiri ndipo sizisintha panthawi yopanga. Mitundu ina ya mapulasitiki imatha kusinthidwanso kuti ikhale ndi mphamvu, komanso kukana kutentha ndi kukhudza. Tiyeni tikambirane za zipangizo zosiyanasiyana za pulasitiki zomwe tingaganizire kutengera momwe gawo lomaliza kapena chinthucho chimagwirira ntchito.
Limodzi mwa ma resin odziwika bwino omwe amagwiritsidwa ntchito popanga zida zamakina ndi nayiloni, yomwe imadziwikanso kuti polyamide (PA). Polyamide ikasakanizidwa ndi molybdenum, imakhala ndi malo osalala kuti isasunthike mosavuta. Komabe, magiya a nayiloni-on-nayiloni sakuvomerezeka chifukwa, monga pulasitiki, nthawi zambiri amamatirana. PA imakhala ndi kukana kuwonongeka ndi kusweka kwambiri, komanso imakhala ndi mphamvu zabwino zamakina kutentha kwambiri. Nayiloni ndi chinthu chabwino kwambiri chosindikizira cha 3D ndi pulasitiki, koma imayamwa madzi pakapita nthawi.

Polyoxymethylene (POM) ndi chisankho chabwino kwambiri pazida zamakanika. POM ndi utomoni wa acetal womwe umagwiritsidwa ntchito popanga DuPont's Delrin, pulasitiki yamtengo wapatali yomwe imagwiritsidwa ntchito mu magiya, zomangira, mawilo ndi zina zambiri. POM ili ndi mphamvu yolimba komanso yopindika, kulimba komanso kuuma. Komabe, POM imawonongeka ndi alkali, chlorine ndi madzi otentha, ndipo zimakhala zovuta kumamatirana.
Ngati polojekiti yanu ndi mtundu wina wa chidebe, polypropylene (PP) ndiye chisankho chabwino kwambiri. Polypropylene imagwiritsidwa ntchito m'zidebe zosungiramo chakudya chifukwa sichimatentha, sichimawotchedwa ndi mafuta ndi zosungunulira, ndipo sichitulutsa mankhwala, zomwe zimapangitsa kuti chikhale chotetezeka kudya. Polypropylene ilinso ndi kulimba bwino komanso mphamvu yokoka, zomwe zimapangitsa kuti zikhale zosavuta kupanga ma loops omwe amatha kupindika mobwerezabwereza popanda kusweka. Ingagwiritsidwenso ntchito m'mapaipi ndi mapayipi.
Njira ina ndi polyethylene (PE). PE ndi pulasitiki yodziwika kwambiri padziko lonse lapansi yokhala ndi mphamvu zochepa, kuuma komanso kuuma. Nthawi zambiri imakhala pulasitiki yoyera ngati mkaka yomwe imagwiritsidwa ntchito popanga mabotolo a mankhwala, zotengera za mkaka ndi sopo. Polyethylene imalimbana kwambiri ndi mankhwala osiyanasiyana koma imakhala ndi malo ochepa osungunuka.
Zipangizo za Acrylonitrile butadiene styrene (ABS) ndizoyenera ntchito iliyonse yomwe imafuna kukana kwambiri komanso kukana kung'ambika kapena kusweka kwambiri. ABS ndi yopepuka ndipo imatha kuwonjezeredwa ndi fiberglass. Ndi yokwera mtengo kuposa styrene, koma imakhala nthawi yayitali chifukwa cha kuuma kwake komanso mphamvu zake. Kupanga chitsanzo cha 3D cha ABS chopangidwa ndi Fusion-molded kuti chigwiritsidwe ntchito mofulumira.
Popeza ili ndi makhalidwe abwino, ABS ndi chisankho chabwino pa zovala zogwiritsidwa ntchito. Ku Star Rapid, tinapanga chikwama cha smartwatch cha E3design pogwiritsa ntchito pulasitiki yakuda ya ABS/PC yopakidwa kale. Kusankha kwa zinthu kumeneku kumapangitsa chipangizo chonse kukhala chopepuka, komanso kupereka chikwama chomwe chingathe kupirira kugwedezeka nthawi zina, monga wotchi ikagunda pamalo olimba. Polystyrene yogwira ntchito kwambiri (HIPS) ndi chisankho chabwino ngati mukufuna chinthu chosinthasintha komanso chosagwedezeka. Zinthuzi ndizoyenera kupanga zikwama za zida zamagetsi zolimba komanso zikwama za zida. Ngakhale kuti HIPS ndi yotsika mtengo, sizimaonedwa kuti ndi zotetezeka ku chilengedwe.
Mapulojekiti ambiri amafuna ma resini opangidwa ndi jakisoni okhala ndi kusinthasintha monga rabala. Thermoplastic polyurethane (TPU) ndi chisankho chabwino chifukwa ili ndi mitundu yambiri yapadera yopangidwa ndi jakisoni wokwera, kutentha kochepa komanso kulimba. TPU imagwiritsidwanso ntchito mu zida zamagetsi, ma rollers, ma cable insulation, ndi zinthu zamasewera. Chifukwa cha kukana kwake kusungunuka, TPU ili ndi kuuma kwambiri komanso mphamvu yodula ndipo ingagwiritsidwe ntchito m'malo ambiri amafakitale. Komabe, imadziwika kuti imayamwa chinyezi kuchokera mumlengalenga, zomwe zimapangitsa kuti zikhale zovuta kukonza panthawi yopanga. Pa jakisoni wopangidwa ndi jakisoni, pali rabala wa thermoplastic (TPR), womwe ndi wotchipa komanso wosavuta kugwira nawo, monga kupanga zingwe za rabala zomwe zimayamwa kugunda kwa shock.
Ngati gawo lanu likufuna magalasi owoneka bwino kapena mawindo, acrylic (PMMA) ndiye yabwino kwambiri. Chifukwa cha kulimba kwake komanso kukana kusweka, nsalu iyi imagwiritsidwa ntchito popanga mawindo osasweka monga plexiglass. PMMA imapukutidwa bwino, imakhala ndi mphamvu yokoka bwino, ndipo ndi yotsika mtengo popanga zinthu zambiri. Komabe, siimakhudzidwa ndi kugwedezeka kapena mankhwala monga polycarbonate (PC).
Ngati polojekiti yanu ikufuna zinthu zolimba, PC ndi yolimba kuposa PMMA ndipo ili ndi mawonekedwe abwino kwambiri, zomwe zimapangitsa kuti ikhale chisankho choyenera cha magalasi ndi mawindo osaphulika. PC ikhoza kupindikanso ndikupangidwa kutentha kwa chipinda popanda kusweka. Izi ndizothandiza popanga ma prototyping chifukwa sizifuna zida zodula za nkhungu kuti zipangidwe. PC ndi yokwera mtengo kuposa acrylic, ndipo kuwonetsedwa nthawi yayitali ndi madzi otentha kumatha kutulutsa mankhwala owopsa, kotero sikukwaniritsa miyezo yotetezeka ya chakudya. Chifukwa cha kukhudzidwa kwake komanso kukana kukanda, PC ndi yabwino kwambiri pa ntchito zosiyanasiyana. Ku Star Rapid, timagwiritsa ntchito izi popanga nyumba za Muller Commercial Solutions zogwiritsidwa ntchito m'manja. Gawolo linapangidwa ndi CNC kuchokera ku PC yolimba; popeza linkafunika kukhala lowonekera bwino, linapakidwa ndi manja ndikupukutidwa ndi nthunzi.
Iyi ndi chidule chachidule cha mapulasitiki ena omwe amagwiritsidwa ntchito kwambiri popanga zinthu. Ambiri mwa awa amatha kusinthidwa ndi ulusi wosiyanasiyana wagalasi, zolimbitsa UV, mafuta odzola kapena ma resin ena kuti akwaniritse zofunikira zina.
Gordon Stiles ndiye woyambitsa komanso purezidenti wa Star Rapid, kampani yopanga zinthu mwachangu, zida mwachangu komanso yopanga zinthu zochepa. Kutengera ndi luso lake la uinjiniya, Stiles adakhazikitsa Star Rapid mu 2005 ndipo motsogozedwa ndi utsogoleri wake kampaniyo yakula kufika pa antchito 250. Star Rapid imagwiritsa ntchito gulu lapadziko lonse la mainjiniya ndi akatswiri omwe amaphatikiza ukadaulo wamakono monga kusindikiza kwa 3D ndi CNC multi-axis machining ndi njira zachikhalidwe zopangira zinthu komanso miyezo yapamwamba. Asanalowe nawo Star Rapid, Styles anali ndi ndikuyendetsa STYLES RPD, kampani yayikulu kwambiri yopanga zinthu mwachangu komanso zopangira zinthu mwachangu ku UK, yomwe idagulitsidwa ku ARRK Europe mu 2000.
