Kev tsim khoom nruab nrab ntawm 500 thiab 1000 units sawv cev rau qhov nyuaj inflection point rau cov pab pawg thiab cov kws kho tshuab. Qhov ntim no zaum hauv thaj tsam grey qhov twgCNC machiningdhau los ua haujlwm- hnyav thiab kim, tseem siab heev - ntim cov cuab yeej nyuaj yuav tsum muaj peev txheej siv nyiaj uas qhov project pob nyiaj yuav tseem tsis tau txhawb nqa. Ntawm Xiamen Dazao Machinery, peb pom ntau txoj haujlwm kaw nyob rau theem no vim yog kev nkag siab tsis zoo ntawm kev lag luam - tawm ntawmCNC vs txhaj molding nqithiab kev ua tau zoo.
Xaiv txoj kev tsis ncaj ncees ua rau ntau tshaj li daim ntawv them nqi siab dua. Nws ua rau kev sib dhos tsis ua haujlwm, cov vaj tsev tsis zoo, thiab lub sijhawm poob. Phau ntawv qhia no txheeb xyuas qhov kev hloov pauv ntawm tus qauv mus rau kev tsim khoom los ntawm lub lens ntawm -kev paub hauv ntiaj teb.
Kev Txhaum Cai Kev Lag Luam ntawm Tsawg Volume Txhaj Molding
Thaum ntsuasCNC vs txhaj molding nqi, buyers feem ntau tsom nkaus xwb rau ntawm daim nqi. Thaum tus nqi ntawm ibtsawg ntim txhaj moldingib feem yuav yog 15 feem pua ntawm CNC machined ib feem, Qhov Tsis yog -Cov Khoom Siv Hluav Taws Xob (NRE) rau cov cuab yeej siv choj tuaj yeem nyob ntawm 3000 USD txog 15000 USD nyob ntawm qhov nyuaj.
CNC Machining Nqi Tsav Tsheb
Rau 500 units, CNC nqi yog tsav los ntawm lub tshuab teev, teem sij hawm, thiab cov cuab yeej hnav.5-axis CNC millingtxo cov teeb suav tab sis lub sij hawm voj voog tseem nyob tas li rau txhua qhov. Tsis muaj kev lag luam ntawm qhov ntsuas tshaj qhov pib qhov programming.
Choj Tooling Nqi Tsav Tsheb
Choj tooling ChinaCov kev xaiv feem ntau siv Al7075 lossis P20 ua ntej-cov hlau tawv. Cov cuab yeej no tso cai rau kev txhaj tshuaj sai. Thawj tus nqi yog thawj pwm tsim thiab fabrication. Rau cov txheej txheem hluav taws xob, qhov tawg -txawm qhov taw tes uas siv cov cuab yeej siv hluav taws xob pheej yig dua li CNC feem ntau tshwm sim ntawm 600 thiab 800 units.
| Feature | CNC Machining (500-1000 units) | Choj Tooling ( Txhaj Molding ) |
| Setup Cost (NRE) | Tsawg (Programming thiab Fixturing) | Nruab nrab mus rau siab (Pwm puag thiab kab noj hniav) |
| Chav tsev Nqe | High (Linear nrog kom muaj nuj nqis) | Tsawg (qis nrog ntim) |
| Lub Sijhawm Lead | 5 rau 10 Hnub | 15 mus rau 25 hnub |
| Khoom siv ntau yam | Yuav luag txhua qhov khoom thaiv | Thermoplastics (ABS, PC, PA66+GF) |
| Tsim Flexibility | Siab (Hloov code tam sim) | Tsawg (yuav tsum tau hloov pwm) |
Technical Barriers: Vim li cas koj tus qauv CNC tuaj yeem ua tsis tiav hauv pwm
Feem ntau manufacturers tham txog tus nqi thiab ceev. Txawm li cas los xij, 24 xyoo ntawm kev ua haujlwm ntawm Dazao tau qhia peb tias kev ua tsis tiav ntawm 500-unit mark feem ntau yog los ntawm peb qhov tshwj xeeb uas cov khoom muag muag tsis quav ntsej.
Internal Stress thiab Dimensional Stability Shifts
CNC machining yog cov txheej txheem rho tawm. Peb pib nrog kev ntxhov siab -relieved block ntawm cov khoom (xws li Al6061-T6 los yog POM-C) thiab tshem tawm yam peb tsis xav tau. Qhov tshwm sim yog dimensionally ruaj khov.
Piv txwv li,tsawg ntim txhaj moldingkoom nrog siab -kev txhaj tshuaj ntawm cov molten resin tom qab txias txias. Cov txheej txheem no qhia txog kev ntxhov siab sab hauv. Rau 1000-unit khiav, yog tias lub qhov rooj qhov chaw lossis cov kab cua txias tsis zoo tsim nyob rau hauv cov cuab yeej choj, cov khoom yuav ua tau raws li qhov kev cia siab tam sim tom qab ejection tab sis warp 48 teev tom qab thaum sib dhos. Yog tias koj lub rooj sib dhos xav tau ntxiv lossis rho tawm 0.02mm kam rau ua hla 200mm ncua, CNC tseem yog qhov kev xaiv zoo dua txawm tias ntawm 1000 units.
Tus Tsim Txiaj Ntsig: Thaum 5000 USD Pwm Ua Khaub Ncaws
Choj cuab yeej yog ua lag luam raws li tus choj rau ntau lawm. Nyob rau hauv kev muaj tiag, nws feem ntau dhau los ua ib tug iteration killer. Peb tau tswj xyuas cov haujlwm uas cov neeg siv khoom txav mus rau kev siv cov cuab yeej txuas ntawm 500 units kom txuag tau 4.00 USD ib feem. Hauv nruab nrab ntawm kev khiav, kev sim teb tau qhia tias cov khoom siv PCB xav tau 1.0 hli ntau dua.
Nrog CNC, peb hloov kho G-code thiab ntu tom ntej yog qhov tseeb. Nrog rau cov cuab yeej choj, koj ntsib lub steel - kev hloov kho kom zoo lossis, qhov phem dua, cov cuab yeej uas tau muab pov tseg. Tsis txhob txav mus rau cov cuab yeej txuas ntxiv tshwj tsis yog tias koj tus qauv tsim nyob rau ntawm 95 feem pua kho lub xeev.
Surface Finish Decay thiab Tool Life Reality
Cov txheej txheem kev lag luam thov yog tias cov cuab yeej siv choj txhuas kav ntev txog 10000 lub voj voog. Thaum lub hauv paus pwm tuaj yeem muaj sia nyob, qhov chaw tseem ceeb tsis ua. Rau siab - zoo nkauj qhov chaw nrog MT-11010 textures los yog siab -gloss tiav, lub abrasive xwm ntawm iav-filled resins (xws li PA66+30%GF) yuav degrade cov pwm parting kab ntev ua ntej 10000th txhaj tshuaj.
Los ntawm chav tsev 800th, koj yuav pom flash lossis poob ntawm kev ntxhib los mos txhais. Ntawm Dazao, peb txo qhov no los ntawm kev siv P20 steel rau choj cov cuab yeej npaj rau iav -cov ntaub ntawv sau, txawm tias 1000-unit xaj.
Case Study: Vim li cas 700 Piece Drone Project Reverted to CNC
Ib tus neeg siv khoom hauv kev lag luam drone tuaj cuag peb nrog kev txiav txim rau 700 airframe Cheebtsam. Thaum xub thawj, lawv thov kom hloov los ntawm CNC machining rauchoj tooling Tuam Tshojcov kev pabcuam kom txo tus nqi tsev ntawm 45.00 USD rau 12.00 USD.
Tus thawj CNC tsim featured txawv phab ntsa thicknesses xws li 1.0mm mus rau 5.0mm kom haum raws li cov qauv tav. Thaum qhov no yooj yim rau tshuab, nws yog ib qho kev puas tsuaj rau kev txhaj tshuaj molding. Cov ntu tuab ua rau cov cim dab dej loj thiab ua kom txias qeeb, thaum cov ntu nyias raug mob los ntawm kev txhaj tshuaj luv luv.
Tus neeg siv khoom tsis tau ua qhov tsim nyogDFM (Design for Manufacturing)tsom xam rau molding. Lawv tau siv 6500 USD rau ntawm lub cuab yeej choj uas tsim cov khoom siv tsis tau. Thaum kawg peb tau rov qab mus rau CNC machining rau cov batch ntawd thaum lawv pab neeg rov tsim dua ib feem rau yav tom ntej 10000-unit txhaj molding khiav. Zaj lus qhia: Ntau lawm ntim dictates tsim, tsis yog lub tshuab.
Dazao Kev txiav txim siab Matrix: Xaiv txoj hauv kev rau koj pawg
Txhawm rau daws koj cov teeb meem kev yuav khoom, ntsuas plaub yam no ua ntej thov kev tsocai:
· Khoom siv:Koj puas xav tau qhov tshwj xeeb molecular orientation ntawm lub molded ib feem, los yog puas yuav cov khoom isotropic ntawm ib tug machined block txaus?
· Sijhawm Sijhawm:Yog tias koj xav tau cov khoom hauv tes hauv 7 hnub rau kev ua lag luam, CNC yog qhov kev xaiv nkaus xwb. Choj tooling yuav tsum muaj tsawg kawg yog 14 hnub rau T1 kuaj.
· Yav tom ntej Scalability:Yog tias 1000 units yog qhov kev sim ua lag luam thiab cov khoom kawg yuav raug txhaj tshuaj molded, siv cov cuab yeej siv choj tam sim no kom siv tau cov txheej txheem molding thiab txo tus nqi.
· Nto tiav:Yog tias koj xav tau ib qho tshwj xeeb molded - hauv kev ntxhib los mos (VDI lossis MT), koj yuav tsum mus nrog kev txhaj tshuaj molding. CNC tsuas yog simulate cov no los ntawm theem nrab hlaws blasting lossis pleev xim.
