Dimensional Tolerances nyob rau hauv OEM Screen Manufacturing: Tswj Mesh Shrinkage
Lub qhov rais screen qhov tseeb qhov tseeb nyob ntawm peb qhov sib txawv: cov khoom siv mesh ruaj khov, kev tsim precision, thiab kev suav txiav txiav. Hauv OEM ntau lawm, qhov sib txawv ntawm qhov sib txawv ntau tshaj ± 2 hli tuaj yeem tsim kev teeb tsa tsis ua haujlwm, cov neeg siv khoom tsis txaus siab, thiab cov nqi lav siab. Cov neeg tsim khoom muab cov ntxaij vab tshaus kev cai yuav tsum tswj mesh shrinkage coefficients, CNC txiav tolerances, thiab thav duab sib dhos variations los ntawm cov ntaub ntawv tswj txheej txheem.
Rau cov neeg muag khoom, cov neeg cog lus, thiab OEM cov neeg yuav khoom, kev nkag siab qhov ntev ntawm qhov siab yog qhov tseem ceeb thaum nrhiav kev cai - qhov loj me ntawm qhov screen rau loj - cov haujlwm ntim.
1. Heat Shrinkage Coefficients: Fiberglass vs. Polyester
Mesh cov ntaub ntawv cuam tshuam qhov sib txawv ntawm qhov kub thiab txias thaum lub sij hawm tsim khoom, warehouses, tsheb thauj mus los, thiab kev teeb tsa.
Thaum tshav kub kub-vim qhov kev hloov pauv yog cuam tshuam los ntawm cov qauv xov paj, txheej txheej txheej, thiab ib puag ncig.
Tej yam kub Shrinkage Performance
| Mesh Khoom | Qhov kub thiab txias | Warp Direction Shrinkage | Weft Direction Shrinkage |
|---|---|---|---|
| Fiberglass Mesh PVC-Coated | 70 degree | Tsawg dua los yog sib npaug li 0.5% | Tsawg dua los yog sib npaug li 0.5% |
| Fiberglass Mesh PVC-Coated | 100 degree | Tsawg dua lossis sib npaug li 1.0% | Tsawg dua lossis sib npaug li 1.0% |
| Polyester Mesh | 70 degree | 1.5%-2.0% | 1.2%-1.8% |
| Polyester Mesh | 100 degree | 2.5%-4.0% | 2.0%-3.5% |
| Pleated Polyester Mesh | 70 degree | 1.8%-2.2% | 1.5%-2.0% |
Fiberglass mesh ua kom pom kev ruaj ntseg zoo dua vim tias cov iav fibers muaj qhov thermal expansion coefficients qis dua li polyester yarns.
Cov txheej txheem xaiv cov khoom siv
| Hom phiaj | Khoom siv pom zoo |
| Cov tsev lag luam | Fiberglass Mesh |
| High -Rise Projects | Fiberglass Mesh |
| Cov Tsev Kho Mob | Fiberglass Mesh |
| Nyob Retractable Systems | Polyester Mesh |
| Pleated Screen Qhov Rooj | Pleated Polyester Mesh |
Rau cov haujlwm nyob rau hauv cov cheeb tsam uas lub thawv kub yuav siab tshaj 60℃thaum thauj, fiberglass mesh feem ntau muab qhov zoo sib xws.
2. CNC Txiav Precision Tolerances (± 1 hli)
Niaj hnub nimno OEM screen factories cia siab rau CNC- tswj cov tshuab txiav kom tswj tau qhov ntev ntawm ntau txhiab units.
Hom Kev Tsim Kho Kom Zoo
| Txheej txheem | Standard Tolerance |
| Mesh Txiav | ± 1.0 hli |
| Aluminium Profile Txiav | ± 0.5 hli |
| Lub Rooj Sib Tham | ± 0.8 hli |
| Ua tiav Screen Dav | ± 1.5 hli |
| Ua tiav Screen Qhov siab | ± 1.5 hli |
Rau cov rooj sib tham loj loj tshaj 1500 mm dav, cov tuam txhab lag luam feem ntau siv cov kev tswj hwm kev sib txuas ntxiv los tiv thaiv qhov dav dav thaum sib dhos.
Kev Tswj Xyuas Cov Ntsiab Lus Zoo
H3: Mesh Squareness Verification (tsawg dua los yog sib npaug rau 1.5 mm Diagonal Difference)
- Ntsuas ob kab pheeb ces kaum
- Qhov sib txawv yuav tsum nyob qis dua 1.5 mm
- Tshawb xyuas txhua pawg ntau lawm
H3: Aluminium Profile Txiav qhov tseeb (± 0.5 hli)
- Digital caliper pov thawj
- Thawj - txheej txheem kev pom zoo
- Kev tshuaj xyuas ntau lawm ib teev
H3: Cov khoom tiav qhov ntev (± 1.5 hli)

Nruab nrab-Cov Lus Pom Zoo Txog Kev Yuav Khoom
Cov neeg muag khoom loj thiab cov neeg ua haujlwm cog lus yuav tsum thov cov ntaub ntawv qhia txog kev muaj peev xwm ua ntej pom zoo ntau lawm.
Rau OEM tej yaam num xav tau kev cai tsim specifications, tshuaj xyuas⇒[OEM kev cai loj qhov rai cov ntxaij vab tshaus]los soj ntsuam cov peev txheej tsim khoom, kev txhawb nqa engineering, thiab cov txheej txheem tswj qhov seem.
3. Muab xam cov nqi txiav tawm rau cov khoom siv rov qab thiab Flush Mount Installations
Installation deductions them nyiaj rau thav duab clearance, manufacturing variation, thiab installation tolerances.
Kev txiav tawm tsis raug tseem yog ib qho ntawm feem ntau ua rau thaj chaw teeb tsa tsis ua haujlwm.
Recessed Mount Deduction Guidelines
| Qhib dav | Pom zoo txiav tawm |
| <600 mm | -2 hli |
| 600-1200 hli | -3 hli |
| 1200-1800 hli | -4 hli |
| >1800 hli | -5 hli |
Flush Mount Deduction Guidelines
| Ncej hom | Pom zoo txiav tawm |
| Aluminium Qhov rai ncej | -2 hli |
| UPVC Ncej | -3 hli |
| Ntoo Ncej | -3-4 hli |
| Kev kho dua tshiab | Yuav tsum muaj kev txheeb xyuas qhov chaw |
Piv txwv xam
Ntsuas qhov dav dav:
1200 hli
Pom zoo txiav tawm:
3 hli
Kev tsim khoom dav:
1200mm - 3mm=1197 hli
Qhov kev txiav tawm no ua kom haum rau thermal expansion, installation variation, thiab manufacturing kam rau ua tsub zuj zuj.
4. Kev txo cov khib nyiab hauv kev txiav - mus rau - Kev txiav txim loj
Kev siv cov khoom siv ncaj qha cuam tshuam rau OEM cov nqi tsim khoom.
Factories ua phav phav ntawm kev cai tshuaj ntsuam qhov ntau thiab tsawg txhua hnub siv optimization software kom txo tau txhuas thiab mesh pov tseg.
Yam khoom siv tus nqi
| Txoj kev tsim khoom | Kev siv cov khoom siv |
| Phau ntawv Nesting | 82%-86% |
| Semi-Automated Optimization | 88%-91% |
| Advanced Nesting Algorithms | 93%-97% |
Piv txwv li Kev Ntsuas Txhuas Txhuas
| Ib xyoos ib zaug | Kev siv cov khoom siv | Qhwv tus nqi |
| 50,000 units | 85% | 15% |
| 50,000 units | 95% | 5% |
Rau lub Hoobkas siv 500 metric tons ntawm txhuas txhua xyoo, kev txhim kho kev siv ntawm 85% mus rau 95% tuaj yeem txo cov seem li ntawm 50 metric tons hauv ib xyoos.
Cov tswv yim txo cov khib nyiab tseem ceeb

Vim li cas Dimensional Tolerance Control Matters rau B2B Buyers
Cov pab pawg muag khoom feem ntau tsom rau cov nqi tsev thaum saib xyuas kev tsim khoom sib xws.
Qhov sib txawv ntawm 1 hli yuav tshwm sim tsis tseem ceeb, tab sis thoob plaws ntau txhiab units nws tuaj yeem ua rau:
- Installation qeeb
- Nce nqi zog ua hauj lwm
- Cov khoom xa rov qab
- Warranty thov
- Qhov project teem caij cuam tshuam
Factories nrog cov ntaub ntawv kev tswj hwm kev ua siab ntev feem ntau xa cov nqi ua tswv cuab qis dua li cov neeg muag khoom xaiv nkaus xwb ntawm tus nqi.
Thov OEM Manufacturing Specifications
Yog tias koj qhov project xav tau kev cai - qhov loj me ntawm cov ntxaij vab tshaus qhov rai, qhov loj me ntawm qhov screen thav duab, lossis tus neeg faib khoom- qhov ntev tshwj xeeb, thov cov ntaub ntawv muaj peev xwm ua ntej kev pom zoo.

Fabrication Tolerance FAQs
Ntev npaum li cas kam rau ua tau rau OEM qhov rai cov ntxaij vab tshaus?
Cov lag luam feem ntau - qib cov tuam txhab tuav cov khoom tiav ntawm ± 1.5 hli, nrog rau qhov profile txiav qhov siab ntawm ± 0.5 hli thiab mesh txiav tolerances ntawm ± 1.0 hli.
Cov khoom siv mesh twg muaj qis dua hauv cov huab cua kub?
PVC-coated fiberglass mesh feem ntau pom tsawg dua 1.0% shrinkage nyob rau hauv qhov kub thiab txias thiab muaj kev ruaj ntseg zoo dua li polyester mesh.
Yuav txiav tawm li cas rau kev cai - qhov loj me ntawm qhov kev txiav txim?
Kev txiav tawm qhov tseem ceeb nyob ntawm hom thav duab, qhib qhov loj, thiab txoj kev mounting. Kev lag luam tej yaam num feem ntau siv txiav tawm ntawm 2 hli thiab 5 hli los xyuas kom meej installation clearance.
