Ib tus neeg saib xyuas kev yuav khoom tsis ntev los no tau nug: "Peb tus neeg muag khoom tsuas yog hais txog kev kho cua sov raws li cov khoom sib cais - qhov no puas yog ib txwm? Peb puas tuaj yeem hla nws los txiav nqi?"
Qhov no yog ib qho ntawm cov nqi pheej yig tshaj -cov lus nug txog hauv hlau 3D luam ntawv cov kev pabcuam. Cov lus teb ncaj ncees yog: Yog, kev kho cua sov ntxiv tus nqi - feem ntau 10–40% ntawm tag nrho cov nqi nyob ntawm cov khoom siv thiab cov txheej txheem nyuaj. Txawm li cas los xij, kev hla nws feem ntau ua rau muaj kev siv nyiaj ntau dua los ntawm cov khoom seem, kev sim ua tsis tiav, qeeb, lossis teeb meem kev tswj hwm.
Vim li cas kev kho cua sov yog tus nqi sib cais hauv Hlau 3D luam ntawv
Nws tsis yog ib feem ntawm Cov Txheej Txheem Luam Ntawv - Nws yog Txoj Haujlwm Sib Cais
SLM luam ntawv xaus thaum lub phaj tsim txias thiab cov khoom raug tshem tawm. Kev kho cua sov yuav tsum muaj cov cuab yeej tshwj xeeb (lub tshuab nqus tsev vacuum, HIP cov hlab ntsha, lub qhov cub laus), cov kws tshaj lij, cov txheej txheem validation, thiab tom qab- tshuaj xyuas kev kho mob. Reputable hlau 3D luam ntawv muab kev pab cuam hais nws cais raws li ib tug kos npe rau ntawm pob tshab, tsis upselling.
Tus nqi tseem ceeb tsav tsheb hauv kev kho cua sov
Khoom siv: Lub tshuab nqus tsev vacuum raug nqi $ 200K– $ 1M+, thaum HIP systems khiav $ 2M– $ 5M+.
Lub Zog & Lub Sij Hawm Sij Hawm: Ntev ntev - qhov kub thiab txias (4–12+ teev).
Batch Efficiency: Cov kev khiav me me muaj ntau dua rau - cov nqi ib feem.
Kev Ua Haujlwm & Txhim Kho: Teeb tsa, thauj khoom, tshem tawm, thiab kuaj xyuas qhov zoo.
Daim ntawv pov thawj: Cov ntaub ntawv, calibration, thiab kev ua raws cai ntxiv nyiaj siv ua haujlwm, tshwj xeeb tshaj yog rau titanium, npib tsib xee alloys, thiab kev lag luam tswj.
Cov ntaub ntawv zoo li npib tsib xee superalloys thiab titanium ELI xav tau cov txheej txheem kim dua li txhuas lossis 316L.
Tus nqi kho cua sov npaum li cas?
Kev Ruaj Ntseg Kev Nyuaj Siab - Qhov Kev Xaiv Muaj Nqi Tshaj Tshaj
Ib qho ntxiv: $ 30– $ 150 ib pob lossis $ 5– $ 30 rau ib feem (cov ntim me me). Parameters: 600-750 degree, 2-4 teev nyob rau hauv lub tshuab nqus tsev los yog inert gas. Qhov zoo tshaj plaws rau: Ua ntej-machining nyem lossis tsis yog{11}} qauv qauv tseem ceeb. Cov nqi poob qis nrog cov khoom loj dua.
Tag Nrho Cov Txheej Txheem thiab Kev Kho Thaum Tshav Kub Kub - Nruab Nrab- Tus Nqi Ntau
Ib qho ntxiv: $ 50 - $ 200 ib feem (cov khoom me me). Xws li kev tswj kom meej thiab feem ntau yog quench kauj ruam. Feem ntau rau AlSi10Mg T6 thiab 17-4PH.
Kev kho mob thiab kev laus (STA) - Tus nqi siab dua, kev ua tau zoo dua
Ib qho ntxiv: $ 100 - $ 400 ib feem. Ntau- cov txheej txheem theem yuav tsum tau tswj nruj. Qhov tseem ceeb rau kev ua haujlwm siab -Ti-6Al-4V thiab IN718.
Kub Isostatic Pressing (HIP) - Qhov kim tshaj plaws, Tab sis siv tau zoo tshaj
Ib qho ntxiv: $200–$800+ ib feem rau cov khoom me me (tuaj yeem tshaj $1,000 rau qhov nyuaj / loj). HIP tus nqi npaum li cas rau 3D luam ntawv hlau qhov chaw? Nws yog ib qho kev tshaj tawm siab tshaj plaws - tus nqi ua haujlwm tab sis muab kev txhim kho loj hauv lub neej qaug zog thiab ceev. Ntau tus neeg muab kev pab cuam outsource HIP, ntxiv logistics thiab 3-10 hnub ua lub sij hawm. Cov nqi poob qis heev nrog cov nkoj puv.

Tiag -Tus Nqi Ntiaj Teb
Scenario 1 - Aerospace Bracket Skipping HIP txuag tau $4,560 ntawm 12 feem tab sis ua rau qaug zog tsis ua hauj lwm raug nqi ntau dua $22,000 hauv tag nrho cov cuam tshuam.
Scenario 2 - Stainless Steel Housing Skipping stress relief saved $1,800 but lead to $4,700 in machining scrap - net poob.
Scenario 3 - Aluminium Prototype Batch Tiered mus kom ze (kev ntxhov siab rau feem ntau, T6 tag nrho rau qhov tseem ceeb) txuag 45% thaum tiv thaiv kev ua haujlwm.
Yog lawm, kev kho cua sov ntxiv tus nqi - feem ntau 10–40% ntawm tag nrho cov nqi ib feem - tab sis feem ntau nws yog ib qho kev nqis peev ntse. Cov lus nug tiag tiag tsis yog tias nws raug nqi nyiaj, tab sis dab tsi hla nws thaum kawg yuav ua rau koj poob rau hauv kev qeeb, ua tsis tiav, lossis poob lub sijhawm.
