Hoobkas teeb rau Acrylic ntau lawm
Nyob rau hauv xya xyoo ntawm fielding nug, tej zaum peb cov neeg tiag tiag xav tsim ib tug acrylic ntau lawm kab los ntawm kos. Lwm tus? Cov neeg ua haujlwm muag khoom, cov kws tsim khoom tsim khoom, cov neeg soj ntsuam zoo-cov neeg sim xyuas seb lub Hoobkas lawv tab tom txiav txim siab puas paub tias lawv ua dab tsi lossis tsuas yog muaj cov duab zoo nkauj ntawm Alibaba.
Ob qho tib si siv ua haujlwm ntawm no. Peb mam li npog cov khoom siv, tus lej, cov khoom tseem ceeb. Tab sis tus nqi tiag tiag yog paub cov lus nug dab tsi nthuav tawm lub khw muaj peev xwm piv rau ib qho uas yuav xa koj cov khib nyiab.
Txoj Kev Yooj Yim Yooj Yim (thiab Vim Li Cas Thiaj Li Tseem Ceeb)
Daim ntawv tuaj nyob rau ntawm 1220 × 2440mm feem ntau. Qee zaum 1200 × 2400, nyob ntawm tus neeg xa khoom. Ua ntej koj txiav nws. Tom qab ntawd txoj kev, laum, zeb-Txawm li cas los xij tus qauv tsim xav tau. Thermal processing rau khoov. Polish. Sau yog xav tau. Sib dhos.
Cov kab ke ntawd tsis yog arbitrary. Muaj ib tus neeg siv khoom ib zaug hais tias peb polish ua ntej qhov kawg routing vim lawv xav tau cov npoo tiav. Suab logical rau lawv. Teeb meem yog routing tom qab polishing pov micro- khib nyiab nyob txhua qhov chaw, khawb qhov polished nto, thiab peb tau rov ua dua tag nrho cov khoom. Plaub caug- xya daim. Tsis loj, tab sis annoying txaus kuv tseem nco ntsoov tus naj npawb.
Point yog, qhov kev ua haujlwm muaj nyob rau vim li cas tsis pom tseeb kom txog thaum koj ntsia nws.
Txiav: Laser vs CNC
CO2 laser yog huab tais rau acrylic. Lub 10.6μm wavelength tau txais yuav luag tag nrho los ntawm PMMA, muab cov npoo uas zoo li nplaim taws - polished ncaj nraim ntawm lub txaj. Peb tau hloov mus rau laser - cov haujlwm tseem ceeb hauv ... 2018? 2019? Nyob ib ncig ntawm ntawd. Ua ntej ntawd peb tau hla txhua yam thiab polished tom qab, uas ua haujlwm tab sis ntxiv cov sijhawm ua haujlwm.
CNC routing tseem tsis tuag. Tsis tuaj yeem laser lub hnab ntim 15mm sib sib zog nqus. Tsis tuaj yeem laser xov. Tsis tau profile ib tug complex ntug nthuav dav. Cov tshuab ua ntau yam.
Kev Pom Kev Txawj Ntse
Nov yog qee yam uas cais cov khw muag khoom zoo los ntawm cov khoom tsis zoo -thiab kuv tsis yog kev hais lus rau qhov no vim nws tseem ceeb: cov cuab yeej sib kis.
