Cast vs Extruded Acrylic Manufacturing Methods

Kuv tau tsim acrylic rau 15 xyoo tam sim no. Pib ntawm lub khw kos npe hauv Phoenix, tsiv mus rau hauv kev ua vaj tse, thiab tam sim no khiav ntau lawm rau cov chaw tsim khoom hauv Midwest. Cov lus nug cam piv rau extruded los tsis tu ncua-los ntawm cov neeg ntiav tshiab, los ntawm cov neeg siv khoom, los ntawm cov engineers uas spec'd cov khoom tsis raug thiab tam sim no xav kom peb kho nws.

Nov yog qhov kuv tau kawm txoj kev nyuaj.

Cam khwb cia acrylic yog poured li kua monomer ntawm iav daim hlau thiab kho maj mam. Extruded acrylic yog melted pellets thawb los ntawm rollers. Qhov ntawd yog nws. Ob leeg yog PMMA. Ob leeg saib zoo ib yam ntawm lub khib.

Qhov teeb meem pib thaum koj sim ua ib yam dab tsi nrog lawv.

Cast vs Extruded Acrylic Manufacturing Methods

Casting yuav siv sij hawm. Ib daim ntawv ib nrab -inch yuav kho tau 12 teev lossis ntau dua. Cov iav pwm xav tau kev saib xyuas tas li. Tsis lees txais cov nqi khiav ntau dua vim tias muaj kev sib kis hauv cov monomer tshwm sim raws li qhov tsis xws luag uas koj kho tsis tau.

Plaskolite khiav ob txheej txheem ntawm lawv qhov chaw Columbus. Lawv cov kab Optix yog extruded, khiav 24/7, cranks tawm footage. Lawv cov kab nrum txav qeeb dua. Tus nqi sib txawv-feem ntau yog 30-40% markup rau cast-reflects tiag tiag kev lag luam, tsis yog kev lag luam.

Evonik's Acrylite zoo ib yam. Qib GP (extruded) raug nqi tsawg dua lawv qib FF (cam khwb cia). Tib lub tuam txhab, tib yam resin chemistry, txheej txheem sib txawv, tus nqi sib txawv.

Qhov no ua rau tib neeg xav tsis thoob. Extruded ntawv tuav nruj dua thickness kam rau ua dua cam khwb cia.

Cov menyuam sib txawv ntawm cov kab extrusion yog mechanically tsau. Koj muab nws rau 0.118 "thiab qhov ntawd yog qhov koj tau txais, ntxiv lossis rho tawm ob peb tus koj. Cov ntawv pov tseg thaum lub sij hawm polymerization, thiab qhov shrinkage sib txawv nyob rau hauv daim ntawv. Ib tug nominally quarter-inch cam khwb cia daim ntawv yuav ntsuas 0.236" nyob rau hauv ib lub ces kaum thiab 0.251" nyob rau hauv lwm yam.

Raws li ASTM D4802, cam khwb cia acrylic tso cai ± 10% thickness variation. Extruded feem ntau tuav ± 5%. Thaum koj nyob nraum machining qhov chaw uas yuav tsum tau pawg lossis haum rau hauv cov channel, qhov no tseem ceeb.

Peb muaj ib txoj hauj lwm xyoo tas los-kev pab cuam muag khoom, 400 units, txhua tus xav tau peb lub txee acrylic zaum hauv aluminium extrusion. Cov neeg siv khoom spec'd nrum vim "nws zoo dua." Thawj batch tuaj rau hauv, rhawv tau khi nyob rau hauv ib nrab ntawm fixtures. Thickness variation. Hloov mus rau extruded, teeb meem daws.

Khiav 60W CO2 laser los ntawm cam khwb cia acrylic ntawm 15mm / s, 85% zog, thiab koj tau txais ib tug polished ntug. Dej- ntshiab. Npaj rau cov neeg siv khoom. Cov khoom vaporizes huv si vim hais tias cov ntev polymer chains sib cais yam tsis muaj seem seem.

Sim ua li ntawd nrog extruded thiab koj tau txais cov ntug frosted. Qee zaum mis nyuj. Qee zaum nrog cov npuas me me raws lub ntsej muag txiav. Koj tuaj yeem kho lub laser-poob zog, nce nrawm, ntxiv huab cua pab-tab sis koj tab tom nrhiav kev rov qab los. Extruded npoo yeej tsis phim cov npoo ntawm lub laser.

Rau kev kos npe, POP qhia, txhua yam ntawm ntug pom, peb siv cam khwb cia. Lub sijhawm. Cov khoom siv tus nqi hwm ploj mus tiv thaiv tus nqi zog ntawm cov nplaim polishing extruded npoo.

Trotec thiab Epilog ob leeg tshaj tawm cov chaw pom zoo rau "acrylic" yam tsis muaj kev qhia meej. Cov kev teeb tsa no ua haujlwm rau cast. Extruded xav tau kev sib txawv.

Cam khwb cia acrylic muaj qhov sib txawv ntawm kwv yees li 40℃F. Koj tuaj yeem rub nws tawm ntawm qhov cub qhov twg los ntawm 340-380℃F thiab nws nyob twj ywm ua haujlwm. Extruded muab rau koj tej zaum 20℃F ntawm lub qhov rais ua ntej nws mus los ntawm nruj heev rau dhau floppy.

Kuv saib ib tug txiv neej tshiab rhuav tshem tag nrho daim ntawv ntawm extruded lub hli tas los. Nws tab tom tsim cov lauj kaub kos npe yooj yim, tsis muaj dab tsi nyuaj. Tau lub qhov cub teem rau cam khwb cia (peb tau khiav nrum txhua lub lim tiam). Thawj rub tawm tau zoo vim tias daim ntawv tau ua tiav. Thib ob rub nws sab laug ntev me ntsis kom them nyiaj - ntev dhau. Cov khoom sagged los ntawm tus ncej ua ntej nws yuav tau mus rau pwm.

Cast zam txim txhaum. Extruded tsis.

Rau kev sib sib zog nqus nqus-txhua yam dhau 2: 1 piv- nrum yog qhov yuav tsum tau ua. Qhov sib txawv molecular hnyav qhia tau tias yog formability. Extruded yuav nyias tawm thiab tsim kua muag qhov twg nrum stretches uniformly.

Ob qho khoom siv ua haujlwm zoo nrog cov khoom noj kom zoo thiab nrawm. Peb khiav Multicam nrog 18K spindle, ib zaug -flute O-ntsis, 120 IPM pub rau lub quarter-inch khoom. Chip clearance yog qhov tseem ceeb. Acrylic melts ntawm 320℃F thiab koj lub router me ntsis ua kom sov los ntawm kev sib txhuam.

Extruded cov pos hniav tuaj sai. Cov luv luv polymer chains soften ntawm qis temps. Peb tsoo cov huab cua blast siab nce 10 PSI thaum khiav extruded thiab txo tus nqi pub los ntawm li 15%. Qee lub khw siv misting coolant tab sis peb twb muaj teeb meem nrog coolant tawm residue nyob rau hauv laser - txiav cov hauj lwm downstream.

Cam khwb cia chips ya tawm huv si. Cov khoom nyob twj ywm nruj dua nyob rau hauv tej kub.

Ib yam tsis muaj leej twg qhia rau koj: extruded muaj kev ntxhov siab ntau ntxiv los ntawm txheej txheem extrusion. Txiav ib txoj hlua nqaim tawm ntawm ntug ntawm ib daim ntawv extruded thiab saib nws nkhaus. Cast zaum tiaj. Qhov kev ntxhov siab no kuj txhais tau hais tias extruded tawg yooj yim dua thaum lub sij hawm machining yog tias koj lub cuab yeej yog npub lossis koj qhov kho kom zoo cia cov ntawv vibrate.

Weld- Ntawm 3 thiab 4 yog cov qauv. Nyias-lub cev MMA-raws li cements. Siv rau kev sib koom ua ke, capillary nkaus rub nws hauv, hnyav flashes tawm, polymer chains tangle ua ke.

Cam khwb cia-rau- cov pob qij txha cam khwb cia muaj zog dua li extruded-rau-extruded. Kuaj rau ASTM D4499, cam khwb cia pob qij txha khiav 3500-4200 PSI shear. Extruded khiav 2400-3000 PSI. Qhov sib txawv molecular hnyav dua.

Tseem ceeb tshaj cov lej: cam khwb cia daim ntawv cog lus zoo dua. Cov cement ntws sib npaug, kho kom meej. Extruded pob qij txha qee zaum qhia me ntsis hazing lossis micro- npuas nyob rau hauv daim ntawv cog lus. Rau cov qauv siv nws tsis muaj teeb meem. Rau cov rooj plaub uas tus neeg siv khoom nyob deb ntawm 6 ntiv tes kuaj xyuas koj txoj haujlwm, nws tseem ceeb.

Cov pob qij txha sib xyaw ua ke- nrum rau extruded- yog qhov tsis paub tseeb. Peb zam lawv thaum ua tau.

Kuv tau siv feem ntau ntawm cov kab lus no piav qhia vim li cas cam khwb cia yog superior. Yog li thaum twg extruded ua rau kev nkag siab?

Daim duab ncej. Lub teeb diffuser panels. Cov neeg tiv thaiv tsis muaj leej twg saib ze. High - cov kev pab cuam ntim qhov twg cov khoom siv tus nqi dominates. Txhua yam tau pleev xim los yog laminated qhov twg ntug zoo yog zais.

Extruded kuj yeej ntawm muaj. Standard sizes nkoj los ntawm kev faib khoom hauv ib hnub lossis ob hnub. Cam khwb cia tej zaum muaj txhuas lub sij hawm, tshwj xeeb tshaj yog txawv thicknesses los yog tints.

Peb khiav roughly 60% cam khwb cia, 40% extruded los ntawm ntim. Qhov sib xyaw ua haujlwm nyob ntawm seb cov haujlwm nyob hauv tsev.

Cov ntawv tsis muaj cim yog mob taub hau. Peb khaws cam khwb cia thiab extruded ntawm nyias racks nrog xim -coded ntug daim kab xev, tab sis cov khoom sib tov thaum tuav.

Qhov ntsuas hnyav ua haujlwm. Muab cov methylene chloride tso rau ntawm qhov chaw. Extruded tig tacky hauv 10-15 vib nas this. Cast resists ntev-30 vib nas this los yog ntau tshaj ua ntej koj pom whitening.

Qee cov qub -timers ua qhov ntsuas nplaim taws ntawm ntug khawb. Cam khwb cia kub nrog tsawg pa luam yeeb thiab poob. Kuv tsis pom zoo qhov no. Ob cov ntaub ntawv muab tawm cov pa taws thaum hlawv thiab qhov sib txawv tsis txaus ntseeg kom ntseeg tau.

Qhov kev xyaum zoo tshaj plaws: tsis txhob tshem cov npog ntsej muag kom txog thaum koj yuav tsum tau ua, thiab kos cov nplooj ntawv liab qab nrog cov xim cwj mem thaum lub ntsej muag tawm.

Plaskolite (Optix, Plaskolite), Evonik (Acrylite), Trinseo (Plexiglas G thiab MC), thiab Arkema (Altuglas) yog cov players loj hauv North America. Txhua tus ua ob qho tib si cam khwb cia thiab extruded qib.

Distributor Tshuag sib txawv raws cheeb tsam. Laird Plastics, Piedmont Plastics, thiab Curbell txhua tus muaj ntau lub npe. Tus nqi hloov pauv-peb tau pom kev sib tw ntawm 15% dhau ib lub hlis twg. Tau txais cov lus hais los ntawm tsawg kawg ob qhov chaw ntawm cov haujlwm loj.

Ntshuam daim ntawv los ntawm Asia khiav pheej yig dua tab sis kev tswj tsis tau zoo. Peb tau txais supposedly cam khwb cia cov ntaub ntawv uas laser - txiav zoo li extruded. Kev ntsuam xyuas cov khoom tuaj yuav txuag kev tu siab tom qab.

Kev xaiv cov khoom yog hais txog cov khoom sib xws rau cov kev xav tau. Cam khwb cia acrylic txheej txheem zoo dua nyob rau hauv feem ntau cov hauj lwm thiab ua ntau dua - zoo tiav qhov chaw. Extruded acrylic nqi tsawg dua thiab ua haujlwm zoo thaum kho kom zoo nkauj tsis tseem ceeb.

Paub qhov koj tab tom yuav. Paub qhov koj cov neeg siv khoom xav tau tiag tiag. Cov khoom siv "zoo dua" yog ib qho uas tau txais txoj haujlwm ua tiav ntawm tus nqi tsim nyog yam tsis muaj kev hu rov qab.
