Kev soj ntsuam zoo tom qab extrusion tuag ua tiav yog ib kauj ruam tseem ceeb hauv kev ua kom zoo tuag, txhim kho kev tsim khoom, thiab lav qhov zoo ntawm cov khoom yas. Cov txheej txheem no suav nrog ntau qhov ntev, suav nrog cov tsos zoo, qhov tseeb qhov tseeb, nto tiav, thiab qhov zoo ntawm cov khoom yas molding txheej txheem. Cov hauv qab no yog cov lus piav qhia ntxaws txog cov qauv tshuaj ntsuam xyuas no.
Kev Pom Zoo Txais Cov Qauv
Cov tsos mob zoo yog tus qauv tseem ceeb rau kev lees paub tuag, cuam tshuam ncaj qha rau kev tuag lub neej thiab kev zoo nkauj ntawm cov khoom yas. Tshwj xeeb, cov qauv kev pom zoo pom zoo suav nrog cov hauv qab no:
1. Die Surface Integrity: Qhov chaw tuag yuav tsum tsis txhob pom cov kab nrib pleb, qhov pores, tsis sib xws, lossis lwm yam tsis xws luag. Cov teeb meem no tsis tsuas yog cuam tshuam rau cov tuag lub zog thiab kev ruaj ntseg tab sis kuj tseem tuaj yeem tso cov cim ntawm cov khoom yas nto, cuam tshuam rau cov khoom zoo nkauj.
2. Nto thiab Core Pwm Matching: Qhov tuag saum npoo thiab cov tub ntxhais pwm saum npoo yuav tsum muaj qhov sib txuam siab, tsis muaj qhov pom tseeb tilting, misalignment, lossis deformation. Qhov no yuav pab xyuas kom meej tias cov khoom yas sib npaug sib npaug thaum lub sij hawm molding, tsis txhob muaj qhov tsis xws luag xws li warping thiab deformation.
3. Nameplates thiab Identification: Lub nameplate cov ntsiab lus yuav tsum ua kom tiav, cov cim meej, thiab zoo zoo, thiab nws yuav tsum tau kho ntawm cov pwm ko taw nyob ze ntawm lub template thiab reference ces kaum. Lub nameplate tsis tsuas yog pab txhawb pwm kev txheeb xyuas thiab kev tswj hwm tab sis kuj tseem yog lub hauv paus tseem ceeb rau pwm zoo traceability.
Dimensional Accuracy Acceptance Standards
Dimensional raug yog ib qho ntawm cov cim tseem ceeb rau kev ntsuas pwm zoo. Nws ncaj qha cuam tshuam rau qhov seem stability thiab interchangeability ntawm cov khoom yas. Dimensional raug lees txais cov qauv feem ntau suav nrog:
1. Dimensional Conformity: Txhua qhov ntev ntawm cov pwm extrusion yuav tsum nruj me ntsis raws li cov qauv tsim hauv cov duab kos. Qhov no suav nrog tag nrho qhov ntev ntawm cov pwm, qhov ntev ntawm qhov tseem ceeb, thiab qhov ntev mating.
2. Kev Tswjhwm kam rau ua: Qhov ntev ntev ntawm cov pwm extrusion yuav tsum ua tau raws li cov kev cai. Dimensional deviations thiab geometric tolerances yuav tsum tsim nyog los xyuas kom meej tias qhov tseeb yuav tsum tau ua raws li thaum ua thiab siv. Piv txwv li, kab noj hniav txoj kab uas hla ntawm kev txhaj tshuaj pwm yuav tsum tsis txhob ntau tshaj 0.01mm, thiab kab noj hniav loj yuav tsum tsis txhob ntau tshaj 0.02mm.
3. Geometric Shape thiab Dimensional Accuracy: Cov duab geometric thiab qhov tseeb ntawm cov khoom yuav tsum ua raws li qhov yuav tsum tau ua ntawm cov pwm qhib kos duab kos duab (los yog cov ntaub ntawv 3D). Rau cov khoom uas yuav tsum tau tshwj xeeb precision, nruj tswj yog tsim nyog raws li kam rau ua. Piv txwv li, qhov kam rau siab rau qhov ntev ntawm qhov ntev yog qhov tsis zoo, thaum lub siab ntev rau qhov qhov ntev yog qhov zoo.
Surface Finish Acceptance Standards
Surface finish yog ib qho tseem ceeb qhia txog qhov zoo ntawm cov pwm ua, ncaj qha cuam tshuam rau qhov zoo ntawm cov khoom yas. Cov txheej txheem kev lees paub qhov saum npoo av feem ntau suav nrog:
1. Nto Smoothness: Cov pwm saum npoo yuav tsum du thiab tiaj, tsis muaj qhov pom tseeb lossis burrs. Cov kev tsis zoo no tsis tsuas yog cuam tshuam rau qhov zoo ntawm cov pwm, tab sis kuj tseem tuaj yeem tawm khawb, hnav, thiab lwm yam cim rau ntawm qhov chaw ntawm cov khoom yas.
2. Post-Moulding Surface Quality: Tom qab molding, qhov saum npoo ntawm cov khoom yas yuav tsum tsis txhob hnav, khawb, warping, thiab lwm yam defects. Cov teeb meem no tsis tsuas yog cuam tshuam rau cov khoom zoo nkauj xwb tab sis kuj tseem tuaj yeem txo nws txoj kev ua tau zoo.
