Technical Comparison Module (Infographic-Hushamwari)
1. Core Process Principles
| Parameter | Yakawedzerwa Grid | Yakadhindwa Grid |
|---|---|---|
| Material Prep | Mutobvu wakanyungudutswa → Kuramba kuchikanda (0.8-2.0mm strip) | Mutobvu wakanyungudutswa → Unoramba uchikunguruka (1.2-3.0mm strip) |
| Kugadzira Nzira | Kurova + Mechanical kutambanudza (18-25m/min) | Precision stamping (300-500 sitiroko / min) |
| Dimensional Tolerance | ±0.2mm | ± 0.05mm (inotsamira mukuumbwa) |
| Key Equipments | Kuwedzera muchina | Progressive die stamping press |
Misiyano Yakakosha:
- Magidhi akadhindwa anovimba nemhando yepamusoro-chaiyo (± 0.05mm) kune yakaoma geometries; magridi akawedzerwa anotungamira kuchinjika nekudzika kwakadzika.
2. Performance Metrics
2.1 Mechanical Simba (ASTM E8 Standard)
| Test Parameter | Yakawedzerwa Grid | Yakadhindwa Grid |
|---|---|---|
| Tensile Simba | 38-42 MPa | 55-62 MPa |
| Elongation paBreak | 15-18% | 8-12% |
| Kuneta Hupenyu (Magedhe) | 5,000 | 8,000+ |
ASTM E8 Kutevedzera:
- Kureba kwegeji: 4D (E8) kana 5D (E8M) yekuenderana gadziriro yemuenzaniso.
- Strain rate: 0.015±0.006 mm/mm/min (yakavharwa-loop control).
2.2 Production Economics (USD/10k Units)
| Cost Category | Yakawedzerwa Grid | Yakadhindwa Grid |
|---|---|---|
| Mutengo Wekushandisa | 0 | 700-1,200 |
| Energy Cost | 120 | 180 |
| Scrap Recycling | 25 | 85 |
| Total Cost | 145 | 965+ |
Kunzwisisa Kwakakosha:
- Madhidhi akadhindwa anounza 75% mutengo wekushandisa, unoshanda chete pakugadzirwa kwakawanda; magridi akawedzerwa anoderedza zvirashwa ne70%, akanakira mapurojekiti asingadhuri.

3. Yakakurudzirwa Mamiriro ezvinhu
| Vadivelu Comedy Technology | Applications |
|---|---|
| Yakawedzerwa Grid | ? Motokari SLI mabhatiri (> 100k zvikamu / mwedzi) |
| ? Mapurojekiti eESS anodhura (40% yakaderera CAPEX) | |
| ? Yakamisikidzwa grid madhizaini (dhaimondi / rectangular mapatani) | |
| Yakadhindwa Grid | ? Kutanga-kumira / kudzika-kutenderera mabhatiri (> 1,200 kutenderera, paIEC 61427) |
| ? Tsika geometries (huchi / radial grids) | |
| ? Yakakwirira-chaiyo kushivirira (ukobvu musiyano |
Scenario Analysis:
- Kutanga-Stop Systems: Yakadhindwa magidhi 'kusimba kwesimba (55-62 MPa) uye kuneta hupenyu (8,000+ kutenderera) zvinosangana kakawanda kubhadharisa-kuburitsa zvinodiwa.
- ESS Projects: Yakawedzerwa ma grids 'mutengo wakakwana (145 USD/10k mayuniti) inokodzera CAPEX-sensitive deployments, ine magadzirirwo akamisikidzwa anogonesa scalability.
Innovation Trends & References
- Yepamusoro Grid Geometries: Madhidhi akadhindwa anogonesa 18% yakakwirira inoshanda kurodha kuburikidza nezvimiro zvehuchi, yakasimbiswa mumapurojekiti e-ESS ekugadzira grid (semuenzaniso, Xinjiang Bazhou Shared ESS).
- Vadivelu Comedy Mold Technology: GREE's ± 0.001mm chaiyo molds uye 380-strokes/min stamping speed iri kukurumidza kugamuchirwa mumabhatiri eEV ekutanga.
