Kev Sib Piv Module (Infographic-Friendly)
1. Cov txheej txheem tseem ceeb
| Parameter | Expanded Grid | Stamped Grid |
|---|---|---|
| Khoom Prep | Molten lead → Nruam casting (0.8-2.0mm strip) | Molten lead → Nruam dov (1.2-3.0mm strip) |
| Txoj kev tsim | Punching + Mechanical stretching (18-25m / min) | Precision stamping (300-500 strokes / min) |
| Dimensional kam rau ua | ± 0.2 hli | ± 0.05 hli (pwm-nyob) |
| Cov cuab yeej tseem ceeb | Expanding tshuab | Progressive tuag stamping xovxwm |
Qhov txawv tseem ceeb:
- Stamped daim phiaj cia siab rau cov pwm ua haujlwm siab (± 0.05mm) rau cov geometry nyuaj; Cov kab sib txuas nthuav dav tseem ceeb ua kom yooj yim nrog qis dua.
2. Kev ntsuas kev ua haujlwm
2.1 Mechanical Strength (ASTM E8 Txuj)
| Test Parameter | Expanded Grid | Stamped Grid |
|---|---|---|
| Tensile zog | 38-42 MPa | 55-62 MPa |
| Elongation ntawm Break | 15-18% | 8-12% |
| Fatigue Life (Cycles) | 5,000 | 8,000+ |
ASTM E8 Kev Ua Raws Cai:
- Ntsuas qhov ntev: 4D (E8) lossis 5D (E8M) rau kev npaj cov qauv zoo ib yam.
- Tus nqi lim: 0.015 ± 0.006 mm / mm / min (kaw-loop tswj).
2.2 Production Economics (USD / 10k units)
| Qeb Nqi | Expanded Grid | Stamped Grid |
|---|---|---|
| Tus nqi cuab yeej | 0 | 700-1,200 Nws |
| Tus nqi zog | 120 | 180 |
| Cov khoom siv rov ua dua tshiab | 25 | 85 |
| Tus nqi tag nrho | 145 | 965+ ib |
Ntsiab kev pom:
- Stamped grids incur 75% tooling tus nqi, siv tau tsuas yog rau ntau lawm; nthuav daim phiaj txo cov nqi seem los ntawm 70%, zoo tagnrho rau cov nqi-rhiab heev.

3. Cov xwm txheej pom zoo
| Technology | Daim ntawv thov |
|---|---|
| Expanded Grid | ? Automotive SLI roj teeb (> 100k units / hli) |
| ? Nqi-sensitive ESS tej yaam num (40% qis CAPEX) | |
| ? Standardized daim phiaj tsim (pob zeb diamond / duab plaub) | |
| Stamped Grid | ? Pib-nres / sib sib zog nqus roj teeb (> 1,200 cycles, ib IEC 61427) |
| ? Kev cai geometries (honeycomb / radial daim phiaj) | |
| ? High-precision kam rau ua (thickness variation |
Kev soj ntsuam scenario:
- Pib-Stop Systems: Stamped grids ' tensile lub zog (55-62 MPa) thiab qaug zog lub neej (8,000+ cycles) ua tau raws li qhov xav tau ntau zaus.
- ESS Projects: Nthuav daim phiaj 'tag nrho cov nqi (145 USD / 10k units) suits CAPEX-sensitive deployments, nrog standardized designs enabling scalability.
Innovation Trends & References
- Advanced Grid Geometry: Stamped daim phiaj pab kom 18% siab dua cov khoom thauj khoom ntawm cov qauv honeycomb, validated nyob rau hauv daim phiaj-forming ESS tej yaam num (xws li, Xinjiang Bazhou Shared ESS).
- Pwm Technology: GREE's ± 0.001mm precision pwm thiab 380-strokes / min stamping ceev tau nrawm rau kev txais yuav hauv cov roj teeb hwm EV.
