A. Txhaj pwm-TV casings, keyboard nyees khawm, hluav taws xob khoom vaj tse, computer peripherals, khoom ua si, khoom siv hauv tsev (feem ntau yog siv)
B. Tshuab pwm-Lub raj mis haus
C. Compression pwm-Bakelite keyboards, technical ceramic tableware
D. Hloov pwm-Cov khoom siv hluav taws xob sib txuas
E. Extrusion pwm-Hoses, hnab yas
F. Thermoforming moulds-Cov pob tshab moulded plhaub
G. Rotational pwm-Soft yas menyuam roj hmab/cov khoom ua si
Cov ntsiab lus tseem ceeb rau kev tsim pwm yas muaj xws li:
1. Lub rooj vag yuav tsum nyob ntawm qhov tuab tshaj plaws ntawm ib feem kom ntseeg tau tias du thiab ua tiav pwm filling;
2. Qhov zoo tshaj plaws, tso lub rooj vag uas nws tsis cuam tshuam rau cov khoom zoo li lossis kev ua haujlwm, xws li raws ntug lossis hauv qab;
3. Lub qhov dej txias yog feem ntau muab tso rau ntawm qhov kawg ntawm tus khiav ze ntawm lub rooj vag, nruab nrog tus pin rub los pab txhawb kev khiav tawm;
4. Rau qhov loj lossis tiaj, ntau- taw tes rooj vag yog pom zoo kom tiv thaiv warping, deformation, lossis txhaj tshuaj luv luv;
5. Qhov chaw ntawm lub rooj vag yuav tsum txo txoj hauv kev ntawm cov yas ntws kom txo qis kev poob siab thiab pab txhawb pwm qhov cua;
6. Tsis txhob tso cov rooj vag ze ntawm cov cores kom tiv thaiv cov kwj deg los ntawm kev cuam tshuam ncaj qha rau cov tub ntxhais, uas tuaj yeem ua rau deformation, misalignment, lossis khoov;
7. Qhov ntev ntawm lub rooj vag nyob ntawm qhov loj me, geometry, qauv, thiab hom yas; ib qho tuaj yeem pib nrog qhov me me thiab kho lawv raws li cov txiaj ntsig kev sim pwm;
8. Siv cov pwm ntws los yog kev paub dhau los los txiav txim siab yog tias cov kab sib txuas (knit kab) tshwm sim los ntawm qhov chaw tso ntawm qhov rooj yuav cuam tshuam rau cov tsos lossis kev ua haujlwm; Cov dej txias slug tuaj yeem ntxiv los txo qhov teeb meem no;
9. Rau ntau-kab kab noj hniav pwm, siv symmetrical gating rau zoo tib yam; Thaum molding qhov sib txawv hauv tib lub pwm, ua ntej tso qhov loj tshaj plaws nyob ze rau lub ntsiab khiav.
Cov ntsiab lus tseem ceeb rau Kev Ceeb Toom
I. Tsis txhob tsom mus rau kev tsim khoom tsim thaum tsis saib xyuas cov pwm tsim khoom.
Thaum lub sij hawm tsim khoom lossis prototyping, qee cov neeg siv tsuas yog tsom rau qhov kev tshawb fawb thiab kev loj hlob ntawm cov khoom, tsis quav ntsej kev sib txuas lus nrog cov chaw tsim khoom yas pwm. Hu rau cov tuam txhab pwm thaum ntxov, thaum tsim cov khoom tsim ua ntej, muaj ob qho txiaj ntsig tseem ceeb:
1. Nws ua kom cov khoom tsim tau zoo rau cov txheej txheem molding zoo, zam qhov yuav tsum tau hloov kho qhov kawg tsim vim kev tsim khoom nyuaj.
2. Nws tso cai rau cov neeg tsim pwm tuaj yeem pib tsim kev npaj ua ntej, tiv thaiv kev saib xyuas los ntawm kev maj nrawm uas tuaj yeem ncua sijhawm ntawm qhov project.
3. Ua tau zoo - cov yas pwm zoo yuav tsum muaj kev sib koom tes zoo ntawm tus neeg muag khoom thiab cov neeg siv khoom; qhov no yog tib txoj hauv kev kom txo tau cov nqi thiab txo cov sij hawm txhuas.
II. Tsis txhob tsom rau tus nqi nkaus xwb; xav txog qhov zoo, lub sijhawm ua haujlwm, thiab kev pabcuam dav dav.
1. Muaj ntau hom pwm, dav categorized rau hauv kaum chav loj. Hom pwm xaiv yog nyob ntawm cov kev cai tshwj xeeb hais txog cov khoom siv, lub cev thiab tshuaj lom neeg, lub zog siv tshuab, qhov tseeb qhov tseeb, qhov ua tiav ntawm qhov chaw, kev pabcuam lub neej, thiab tus nqi -kev ua tau zoo.
2. High-precision pwm yuav tsum tau machining ntawm siab- precision CNC tshuab cuab yeej thiab nruj me ntsis ua raws li cov khoom thiab cov txheej txheem molding; lawv kuj xav tau kev siv CAD/CAE/CAM technologies rau kev tsim thiab tshuaj xyuas.
3. Qee qhov chaw muaj cov txheej txheem molding tshwj xeeb uas yuav tsum tau ua cov thev naus laus zis xws li cov tshuab kub khiav, roj- pab molding, lossis nitrogen gas cylinders.
4. Cov neeg tsim khoom yuav tsum muaj cov khoom siv xws li CNC tshuab, EDM (Electrical Discharge Machining) units, xaim - txiav EDM tshuab, CNC luam milling tshuab, siab - precision grinders, thiab siab - CMMs (Kev Sib Koom Tes Ntsuas Tshuab), nrog rau kev tsim lub tshuab computer thiab cov software cuam tshuam.
5. Rau cov pwm stamping loj (xws li cov khoom siv rau lub tsheb lub cev), cov khoom xws li xovxwm qhov khoob - tuav mechanism, ntug lubrication systems, thiab ntau - chaw nres tsheb muaj peev xwm yuav tsum tau txiav txim siab. Tshaj li xovxwm tonnage, ib tug kuj yuav tsum xav txog tus nqi stroke, pub mechanisms, thiab kev tiv thaiv systems rau ob lub xovxwm thiab pwm.
6. Tsis yog txhua lub tuam txhab muaj lossis tau ua tiav cov txheej txheem tsim khoom thiab cov txheej txheem saum toj no. Thaum xaiv ib tus neeg koom tes, nws yog ib qho tseem ceeb rau kev ntsuam xyuas lawv cov peev xwm tsim khoom- saib tshaj kho vajtse los txiav txim siab txog cov qauv kev tswj hwm, kev siv tshuab, thiab kev txawj ntse.
7. Cov lus hais los ntawm cov tuam txhab sib txawv rau tib lub pwm tuaj yeem sib txawv. Koj yuav tsum them tsis yog ntau tshaj qhov pwm tus nqi tseeb lossis tsawg dua nws cov nqi tiag. Zoo li koj tus kheej lub lag luam, cov tuam txhab pwm yuav tsum tau txais txiaj ntsig tsim nyog. Kev txiav txim pwm raws li qhov tshwj xeeb tsis tshua muaj nqe lus feem ntau yog qhov pib ntawm teeb meem. Cov neeg siv yuav tsum ua qhov kev ntsuam xyuas dav raws li lawv cov kev xav tau tshwj xeeb.
III. Tsis txhob cuam tshuam nrog ntau tog; Qhov zoo tshaj plaws, xaiv qhov kev pabcuam "ib-stop" uas suav nrog ob qho tib si yas pwm tsim thiab ua cov khoom lag luam.
1. Muaj cov pwm tsim nyog (ib qho uas tsim cov qauv kuaj pom zoo) tsis lav qhov loj ntawm cov khoom tsim nyog. Kev vam meej yog nyob ntawm qhov kev xaiv ntawm cov tshuab ua haujlwm, cov molding tsis (xws li kub thiab lub sij hawm voj voog), thiab kev txawj ntse ntawm cov neeg ua haujlwm.
2. Lub siab- pwm zoo yuav tsum muaj siab- zoo molding ua; yog li ntawd, kev sib koom ua ke "ib qho - nres" kev pabcuam yog qhov zoo dua los txo qis qhov xav tau kev sib koom tes ntawm ntau tog. Yog tias qhov kev npaj no tsis ua tau, ib tog neeg yuav tsum raug xaiv los ua lub luag haujlwm tag nrho, thiab qhov kev npaj no yuav tsum tau hais meej meej hauv daim ntawv cog lus.
