nylon abs pp pom abs pulasitiki ndodo fakitale

Pali mapulasitiki masauzande ambiri pamsika kuti apange ma prototyping mwachangu kapena ang'onoang'ono - kusankha pulasitiki yoyenera pulojekiti inayake kungakhale kovuta, makamaka kwa omwe akufuna kupanga kapena ochita bizinesi. Chilichonse chimayimira kusagwirizana malinga ndi mtengo, mphamvu, kusinthasintha ndi kutha kwa pamwamba. Ndikofunika kuganizira osati kungogwiritsa ntchito gawo kapena mankhwala, komanso malo omwe adzagwiritsidwe ntchito.
Nthawi zambiri, mapulasitiki aumisiri asintha zinthu zamakina zomwe zimapereka kulimba kwambiri ndipo sizisintha panthawi yopanga. Mitundu ina ya mapulasitiki imatha kusinthidwanso kuti ikhale ndi mphamvu, komanso kukhudzidwa ndi kutentha. Tiyeni tilowe muzinthu zosiyanasiyana zapulasitiki kuti tiganizire kutengera momwe gawo lomaliza limagwira ntchito.
Chimodzi mwazinthu zomwe zimagwiritsidwa ntchito popanga zida zamakina ndi nayiloni, yomwe imadziwikanso kuti polyamide (PA). Polyamide ikasakanizidwa ndi molybdenum, imakhala ndi malo osalala kuti azitha kuyenda mosavuta. Komabe, zida za nayiloni pa nayiloni sizikulimbikitsidwa chifukwa, monga mapulasitiki, amakonda kumamatirana. PA imakhala ndi mavalidwe apamwamba komanso kukana kwa abrasion, komanso makina abwino pamatenthedwe apamwamba. Nayiloni ndi chinthu choyenera kusindikiza cha 3D ndi pulasitiki, koma imatenga madzi pakapita nthawi.

Polyoxymethylene (POM) ndi chisankho chabwino kwambiri pamakina. POM ndi utomoni wa acetal womwe umagwiritsidwa ntchito popanga DuPont's Delrin, pulasitiki yamtengo wapatali yomwe imagwiritsidwa ntchito mu giya, zomangira, mawilo ndi zina zambiri. POM ili ndi mphamvu zosinthika kwambiri komanso zolimba, zolimba komanso zolimba. Komabe, POM imawonongeka ndi alkali, klorini ndi madzi otentha, ndipo zimakhala zovuta kumamatirana.
Ngati polojekiti yanu ndi chidebe chamtundu wina, polypropylene (PP) ndiye chisankho chabwino kwambiri. Polypropylene imagwiritsidwa ntchito m'zotengera zosungiramo chakudya chifukwa imalimbana ndi kutentha, yosagonjetsedwa ndi mafuta ndi zosungunulira, ndipo sichitulutsa mankhwala, zomwe zimapangitsa kuti zikhale zotetezeka kudya. Polypropylene ilinso ndi kulimba kwabwino kwambiri komanso kulimba kwamphamvu, zomwe zimapangitsa kuti zikhale zosavuta kupanga malupu omwe amatha kupindika mobwerezabwereza osathyoka. Itha kugwiritsidwanso ntchito mu mapaipi ndi mapaipi.
Njira ina ndi polyethylene (PE). PE ndi pulasitiki yodziwika kwambiri padziko lonse lapansi yokhala ndi mphamvu zochepa, zolimba komanso zolimba. Nthawi zambiri amakhala pulasitiki yoyera yamkaka yomwe imagwiritsidwa ntchito popanga mabotolo amankhwala, mkaka ndi zotsukira. Polyethylene imagonjetsedwa kwambiri ndi mankhwala osiyanasiyana koma imakhala ndi malo otsika osungunuka.
Zinthu za Acrylonitrile butadiene styrene (ABS) ndizoyenera pulojekiti iliyonse yomwe imafuna kukana kwambiri komanso kung'ambika komanso kusweka. ABS ndi yopepuka ndipo imatha kulimbikitsidwa ndi fiberglass. Ndiwokwera mtengo kuposa styrene, koma imakhala nthawi yayitali chifukwa cha kuuma kwake ndi mphamvu zake. Fusion-molded ABS 3D modelling for prototyping mwachangu.
Chifukwa cha mawonekedwe ake, ABS ndi chisankho chabwino pazovala. Ku Star Rapid, tidapanga smartwatch case ya E3design pogwiritsa ntchito jekeseni wakuda wa ABS/PC pulasitiki wakuda. Kusankha kwazinthu izi kumapangitsa kuti chipangizo chonsecho chikhale chopepuka, komanso chimapereka mlandu womwe ungathe kupirira kugwedezeka kwanthawi zina, monga wotchi ikagunda molimba. High impact polystyrene (HIPS) ndi chisankho chabwino ngati mukufuna zinthu zosunthika komanso zosagwira ntchito. Izi ndizoyenera kupanga zida zamphamvu zolimba komanso zida za zida. Ngakhale ma HIPS ndi otsika mtengo, samaganiziridwa kuti ndi okonda zachilengedwe.
Ma projekiti ambiri amafunikira jakisoni woumba utomoni wokhala ndi mphamvu ngati mphira. Thermoplastic polyurethane (TPU) ndi yabwino chifukwa ili ndi mapangidwe ambiri apadera a elasticity, kutentha kochepa komanso kukhazikika. TPU imagwiritsidwanso ntchito pazida zamagetsi, zodzigudubuza, zotsekereza chingwe, ndi zinthu zamasewera. Chifukwa cha kukana kwake zosungunulira, TPU ali mkulu abrasion ndi kukameta ubweya mphamvu ndipo angagwiritsidwe ntchito m'madera ambiri mafakitale. Komabe, amadziwika kuti amatenga chinyezi kuchokera mumlengalenga, zomwe zimapangitsa kuti zikhale zovuta kukonza panthawi yopanga. Pakuumba jekeseni, pali mphira wa thermoplastic (TPR), yomwe ndi yotsika mtengo komanso yosavuta kuyigwira, monga yopangira mphira wochititsa mantha.
Ngati gawo lanu likufuna magalasi omveka bwino kapena mawindo, acrylic (PMMA) ndi yabwino. Chifukwa cha kuuma kwake komanso kukana kwa abrasion, zinthuzi zimagwiritsidwa ntchito popanga mawindo osasunthika monga plexiglass. PMMA imapukutanso bwino, imakhala ndi mphamvu zokhazikika, ndipo imakhala yotsika mtengo pakupanga voliyumu yayikulu. Komabe, sizimakhudzidwa kapena kugonjetsedwa ndi mankhwala monga polycarbonate (PC).
Ngati pulojekiti yanu ikufuna zinthu zamphamvu, PC ndi yamphamvu kuposa PMMA ndipo ili ndi mawonekedwe abwino kwambiri opangira magalasi ndi mazenera opanda zipolopolo. PC imatha kupindika ndikupanga kutentha kwachipinda popanda kusweka. Izi ndizothandiza kwa prototyping chifukwa sizifuna zida za nkhungu zodula kuti zipange. PC ndi yokwera mtengo kuposa acrylic, ndipo kuwonetsedwa kwa nthawi yayitali kumadzi otentha kumatha kutulutsa mankhwala owopsa, kotero sikumakwaniritsa miyezo yachitetezo cha chakudya. Chifukwa cha kukhudzidwa kwake komanso kukana kukanika, PC ndiyabwino pazogwiritsa ntchito zosiyanasiyana. Ku Star Rapid, timagwiritsa ntchito izi kupanga nyumba zapam'manja za Muller Commercial Solutions. Gawoli linali CNC machined kuchokera chipika olimba PC; popeza anafunikira kuoneka bwino, ankaupaka mchenga ndi manja ndi kupukuta nthunzi.
Ichi ndi chidule chachidule cha mapulasitiki omwe amagwiritsidwa ntchito kwambiri popanga. Zambiri mwa izi zitha kusinthidwa ndi ulusi wamagalasi osiyanasiyana, zolimbitsa thupi za UV, mafuta odzola kapena ma resins ena kuti akwaniritse zofunikira zina.
Gordon Stiles ndiye woyambitsa komanso purezidenti wa Star Rapid, kampani yojambula mwachangu, yopanga zida mwachangu komanso yopanga ma voliyumu ochepa. Kutengera luso lake laukadaulo, Stiles adakhazikitsa Star Rapid mu 2005 ndipo pansi pa utsogoleri wake kampaniyo idakula mpaka antchito 250. Star Rapid imagwiritsa ntchito gulu lapadziko lonse la mainjiniya ndi akatswiri omwe amaphatikiza matekinoloje otsogola monga kusindikiza kwa 3D ndi makina a CNC amitundu yambiri ndi njira zachikhalidwe zopangira komanso miyezo yapamwamba kwambiri. Asanalowe nawo ku Star Rapid, masitayelo anali ndi STYLES RPD, kampani yayikulu kwambiri yaku UK yowonera komanso kugwiritsa ntchito zida, yomwe idagulitsidwa ku ARRK Europe mu 2000.
