Lub precision ntawm PET preform pwm ncaj qha cuam tshuam qhov zoo ntawm cov khoom kawg. Yog li ntawd, manufacturers yuav tsum tau ua ib tug series ntawm kev ntsuas thaum lub sij hawm ntau lawm kom ntseeg tau siab pwm precision. Cov hauv qab no yog cov txheej txheem tseem ceeb thiab cov thev naus laus zis siv los ntawm PET preform pwm manufacturers kom paub meej:
1. Kev ua kom zoo ntawm cov txheej txheem tsim thiab tsim khoom
Pwm tsim yog thawj kauj ruam hauv kev ua kom muaj tseeb. Cov neeg tsim khoom feem ntau siv cov khoos phis tawj siab heev- pab tsim (CAD) thiab khoos phis tawj- pabcuam kev tsim khoom (CAM) technologies rau 3D qauv thiab simulation tsom xam ntawm pwm. Los ntawm kev simulation, tej zaum cov teeb meem hauv kev tsim qauv tuaj yeem txheeb xyuas ua ntej thiab ua kom zoo. Tsis tas li ntawd, cov pwm tsim cov qauv tsim yuav tsum xav txog yam xws li cov khoom siv thermal expansion, txias efficiency, thiab venting kev ua tau zoo los xyuas kom meej cov pwm stability thiab precision thaum txhaj molding.
Hais txog cov txheej txheem tsim khoom, cov tuam txhab siv high - precision CNC machining chaw rau kev ua pwm. Cov khoom siv CNC tuaj yeem ua tiav micron -theem machining precision, kom ntseeg tau tias qhov ntev thiab cov duab ntawm txhua yam pwm ua tau raws li cov qauv tsim. Tib lub sijhawm, cov pwm tseem ceeb (xws li cov kab noj hniav, cores, ejector pins, thiab lwm yam) feem ntau yog ua los ntawm siab -hardness, siab- hnav- cov ntaub ntawv resistant, xws li siab - zoo alloy steel, thiab lawv hardness thiab kev pab cuam lub neej yog zoo dua los ntawm kev kho cua sov txheej txheem.
2. Kev xaiv khoom thiab kev tswj xyuas zoo
Kev xaiv cov khoom siv pwm yog qhov tseem ceeb rau kev txiav txim siab. PET preform pwm yuav tsum tiv taus qhov kub thiab txias, kev kub siab, thiab kev txhaj tshuaj ntau zaus; Yog li ntawd, cov ntaub ntawv uas muaj zog, siab hnav tsis kam, thiab thermal stability yuav tsum tau xaiv. Feem ntau siv cov pwm hlau xws li P20, H13, thiab S136, uas muaj cov khoom siv zoo thiab kev kho cua sov.
Thaum lub sij hawm cov txheej txheem kev yuav khoom, manufacturers nruj me ntsis tswj cov khoom zoo, xyuas kom meej tias lawv cov tshuaj muaj pes tsawg leeg, txhua yam khoom, thiab kev kho cua sov ua tau raws li cov qauv. Nyob rau tib lub sijhawm, txhua yam ntawm cov pwm tau kuaj xyuas nruj ua ntej ua, suav nrog qhov ntev, qhov roughness, thiab hardness, kom ntseeg tau tias nws ua tau raws li cov qauv tsim.
3. Cov khoom siv machining thiab txheej txheem tswj
High -cov cuab yeej machining precision yog qhov tseem ceeb kom ntseeg tau tias pwm precision. Kev ua haujlwm ntawm PET preform pwm feem ntau xav tau CNC milling tshuab, CNC lathes, hluav taws xob tawm machining (EDM), thiab cov khoom siv hlau txiav. Cov tshuab no ua rau siab - precision machining, kom ntseeg tau qhov tseeb ntawm qhov ntev thiab cov duab ntawm txhua qhov pwm.
Thaum lub sij hawm ua, manufacturers nruj me ntsis tswj kev ua tsis xws li txiav ceev, pub tus nqi, thiab qhov tob ntawm txiav kom paub meej qhov zoo thiab qhov tseeb ntawm qhov machined nto. Tib lub sijhawm, cov pwm ua tiav ntau yam kev ntsuas thiab kev tshuaj xyuas thaum ua haujlwm kom ntseeg tau tias nws ua tau raws li cov qauv tsim.
4. Kev kho cua sov thiab kev kho deg
Kev kho cua sov yog txheej txheem tseem ceeb rau kev txhim kho hardness thiab hnav tsis kam ntawm cov khoom pwm. Tom qab ua tiav, PET preform pwm feem ntau dhau los ua cov txheej txheem kho cua sov xws li quenching thiab tempering los txhim kho lawv cov tawv tawv thiab hnav tsis kam. Thaum lub sij hawm kho cua sov, manufacturers nruj me ntsis tswj qhov kub thiab txias, lub sij hawm, thiab txias npaum li cas los xyuas kom meej cov pwm mus txog nws cov kev ua tau zoo.
Tsis tas li ntawd, kev kho saum npoo ntawm cov pwm kuj yog ib qho tseem ceeb hauv kev ua kom muaj qhov tseeb. Feem ntau siv cov txheej txheem kho saum npoo muaj xws li nitriding, chrome plating, thiab PVD txheej. Cov txheej txheem kho saum npoo no txhim kho pwm qhov hnav tsis kam, tiv thaiv corrosion, thiab kev ua haujlwm zoo, yog li txuas nws lub neej kev pab cuam thiab ua kom muaj tseeb thaum txhaj tshuaj molding.
