Muaj ntau txhiab hom yas hauv khw rau kev tsim qauv sai lossis kev tsim khoom me me - kev xaiv cov yas zoo rau ib qho project tshwj xeeb tuaj yeem nyuaj heev, tshwj xeeb tshaj yog rau cov neeg xav tsim khoom lossis cov neeg xav ua lag luam. Txhua yam khoom siv sawv cev rau kev sib haum xeeb hauv cov nqe lus ntawm tus nqi, lub zog, kev ywj pheej thiab qhov tiav ntawm qhov chaw. Nws yog ib qho tsim nyog los xav txog tsis yog tsuas yog kev siv ntawm qhov lossis cov khoom, tab sis kuj tseem ceeb rau ib puag ncig uas nws yuav raug siv.
Feem ntau, cov yas engineering muaj cov khoom siv kho tshuab zoo dua uas ua rau muaj kev ruaj khov dua thiab tsis hloov pauv thaum lub sijhawm tsim khoom. Qee hom yas kuj tseem tuaj yeem hloov kho kom txhim kho lawv lub zog, nrog rau kev cuam tshuam thiab kev tiv taus cua sov. Cia peb kawm txog cov khoom siv yas sib txawv kom xav txog nyob ntawm qhov ua haujlwm ntawm qhov kawg lossis khoom.
Ib qho ntawm cov resins feem ntau siv los ua cov khoom siv kho tshuab yog nylon, tseem hu ua polyamide (PA). Thaum polyamide sib xyaw nrog molybdenum, nws muaj qhov chaw du rau kev txav mus los yooj yim. Txawm li cas los xij, cov iav nylon-rau-nylon tsis pom zoo vim tias, zoo li cov yas, lawv feem ntau lo ua ke. PA muaj kev tiv thaiv kev hnav thiab kev puas tsuaj siab, thiab cov khoom siv kho tshuab zoo ntawm qhov kub siab. Nylon yog cov khoom siv zoo tagnrho rau 3D luam ntawv nrog yas, tab sis nws nqus dej dhau sijhawm.
Polyoxymethylene (POM) kuj yog ib qho kev xaiv zoo heev rau cov khoom siv kho tshuab. POM yog ib qho acetal resin siv los ua DuPont's Delrin, ib qho yas muaj nqis siv rau hauv cov iav, ntsia hlau, log thiab ntau ntxiv. POM muaj lub zog flexural thiab tensile siab, rigidity thiab hardness. Txawm li cas los xij, POM raug rhuav tshem los ntawm alkali, chlorine thiab dej kub, thiab nyuaj rau lo ua ke.
Yog tias koj qhov project yog ib yam khoom siv hauv lub thawv, polypropylene (PP) yog qhov kev xaiv zoo tshaj plaws. Polypropylene siv rau hauv cov thawv khaws khoom noj vim nws tiv taus cua sov, tsis nkag mus rau cov roj thiab cov kuab tshuaj, thiab tsis tso cov tshuaj lom neeg tawm, ua rau nws muaj kev nyab xeeb rau kev noj. Polypropylene kuj muaj qhov sib npaug zoo ntawm kev tawv thiab lub zog cuam tshuam, ua rau nws yooj yim los ua cov voj voog uas tuaj yeem khoov ntau zaus yam tsis tawg. Nws kuj tseem siv tau rau hauv cov kav dej thiab cov hoses.
Lwm txoj kev xaiv yog polyethylene (PE). PE yog cov yas uas siv ntau tshaj plaws hauv ntiaj teb uas tsis muaj zog, tsis tawv thiab tsis khov. Feem ntau nws yog cov yas dawb zoo li mis nyuj siv los ua cov fwj tshuaj, cov thawv mis nyuj thiab cov thawv ntxuav khaub ncaws. Polyethylene tiv taus ntau yam tshuaj lom neeg tab sis nws muaj qhov kub thiab txias qis.
Cov khoom siv Acrylonitrile butadiene styrene (ABS) zoo tagnrho rau txhua qhov project uas xav tau kev tiv taus kev cuam tshuam siab thiab kev tiv taus kev rhuav thiab tawg. ABS yog lub teeb thiab tuaj yeem txhawb nqa nrog fiberglass. Nws kim dua li styrene, tab sis kav ntev dua vim nws qhov nyuaj thiab lub zog. Fusion-molded ABS 3D modeling rau kev tsim qauv sai.
Vim nws cov khoom, ABS yog qhov kev xaiv zoo rau cov khoom siv hnav tau. Ntawm Star Rapid, peb tau tsim lub thawv smartwatch rau E3design siv cov yas ABS/PC dub uas tau pleev xim ua ntej. Qhov kev xaiv cov khoom siv no ua rau tag nrho lub cuab yeej sib dua, thaum tseem muab lub thawv uas tuaj yeem tiv taus qee zaum, xws li thaum lub moos ntaus rau ntawm qhov chaw tawv. Polystyrene muaj zog (HIPS) yog qhov kev xaiv zoo yog tias koj xav tau cov khoom siv uas siv tau ntau yam thiab tiv taus kev cuam tshuam. Cov khoom siv no yog qhov tsim nyog rau kev ua cov thawv cuab yeej hluav taws xob ruaj khov thiab cov thawv cuab yeej. Txawm hais tias HIPS pheej yig, lawv tsis suav tias yog tus phooj ywg ib puag ncig.
Muaj ntau qhov project uas xav tau cov tshuaj txhaj molding uas muaj elasticity zoo li roj hmab. Thermoplastic polyurethane (TPU) yog ib qho kev xaiv zoo vim nws muaj ntau cov qauv tshwj xeeb rau elasticity siab, kev ua haujlwm kub qis thiab kev ruaj khov. TPU kuj tseem siv rau hauv cov cuab yeej hluav taws xob, cov menyuam, cov khoom rwb thaiv tsev cable, thiab cov khoom siv kis las. Vim nws tsis kam rau cov kuab tshuaj, TPU muaj lub zog sib txhuam thiab shear siab thiab tuaj yeem siv rau hauv ntau qhov chaw ua haujlwm. Txawm li cas los xij, nws paub txog kev nqus cov dej noo los ntawm huab cua, ua rau nws nyuaj rau ua thaum lub sijhawm tsim khoom. Rau kev txhaj molding, muaj roj hmab thermoplastic (TPR), uas pheej yig thiab yooj yim rau kev tuav, xws li kev ua cov roj hmab tuav uas nqus tau kev co.
Yog tias koj qhov khoom xav tau cov iav lossis qhov rai uas pom tseeb, acrylic (PMMA) yog qhov zoo tshaj plaws. Vim nws lub zog thiab kev tiv taus kev sib txhuam, cov khoom siv no yog siv los ua cov qhov rai uas tsis tawg xws li plexiglass. PMMA kuj tseem ua kom ci ntsa iab zoo, muaj lub zog tensile zoo, thiab pheej yig rau kev tsim khoom ntau. Txawm li cas los xij, nws tsis tiv taus kev cuam tshuam lossis tshuaj lom neeg zoo li polycarbonate (PC).
Yog tias koj qhov project xav tau cov khoom siv muaj zog dua, PC muaj zog dua PMMA thiab muaj cov khoom siv kho qhov muag zoo heev, ua rau nws yog qhov kev xaiv zoo rau cov iav thiab cov qhov rai tiv thaiv mos txwv. PC kuj tseem tuaj yeem khoov thiab tsim ntawm chav tsev kub yam tsis tawg. Qhov no muaj txiaj ntsig zoo rau prototyping vim nws tsis xav tau cov cuab yeej pwm kim los tsim. PC kim dua acrylic, thiab kev raug dej kub ntev tuaj yeem tso cov tshuaj lom neeg phem, yog li nws tsis ua tau raws li cov qauv kev nyab xeeb zaub mov. Vim nws qhov cuam tshuam thiab kev tiv thaiv khawb, PC zoo tagnrho rau ntau yam kev siv. Ntawm Star Rapid, peb siv cov khoom siv no los ua cov tsev rau Muller Commercial Solutions handheld terminals. Qhov seem yog CNC machined los ntawm ib lub thaiv khov kho ntawm PC; txij li nws xav tau kom pob tshab tag nrho, nws tau xuab zeb los ntawm tes thiab ua kom huv si.
Qhov no tsuas yog kev piav qhia luv luv ntawm qee cov yas siv feem ntau hauv kev tsim khoom. Feem ntau ntawm cov no tuaj yeem hloov kho nrog ntau yam iav fibers, UV stabilizers, roj nplua nyeem lossis lwm yam resins kom ua tiav qee yam kev qhia tshwj xeeb.
Gordon Stiles yog tus tsim thiab tus thawj tswj hwm ntawm Star Rapid, lub tuam txhab tsim qauv sai, cov cuab yeej siv sai thiab cov tuam txhab tsim khoom tsawg. Raws li nws keeb kwm yav dhau los engineering, Stiles tau tsim Star Rapid hauv xyoo 2005 thiab nyob rau hauv nws txoj kev coj noj coj ua lub tuam txhab tau loj hlob mus txog 250 tus neeg ua haujlwm. Star Rapid ntiav ib pab pawg thoob ntiaj teb ntawm cov engineers thiab cov kws tshaj lij uas sib xyaw cov thev naus laus zis tshiab xws li 3D printing thiab CNC multi-axis machining nrog cov txheej txheem tsim khoom ib txwm muaj thiab cov qauv zoo. Ua ntej koom nrog Star Rapid, Styles muaj thiab ua haujlwm STYLES RPD, lub tuam txhab tsim qauv sai thiab cov cuab yeej loj tshaj plaws hauv UK, uas tau muag rau ARRK Europe hauv xyoo 2000.
