A Joma style blade is an advanced snow plow cutting edge designed with rubber-encased carbide segments that flex independently, allowing precise contouring to road surfaces. This articulating design improves snow clearance, reduces vibration, extends wear life, and minimizes salt usage. SENTHAI manufactures these high-performance blades for OEMs and wholesalers, ensuring durable, reliable, and cost-effective solutions for highways and municipal roads.
How Is a Joma Style Blade Constructed?
Joma style blades feature 3- or 4-foot sectional carbide-reinforced steel segments encased in durable rubber. These segments attach to plows via a clamp bar and adapter blade, allowing independent articulation to match road contours. SENTHAI produces these blades using premium tungsten carbide, combining automated wet grinding, sintering, and welding for superior wear resistance.
The bolt-on design enables quick field replacement, reducing downtime. Each steel segment supports 0.955-inch carbide inserts to enhance ice-cutting efficiency. SENTHAI ensures strict ISO-certified quality control for consistent performance across global operations.
| Component | Material | Purpose |
|---|---|---|
| Carbide Insert | Tungsten Carbide | Cuts through ice and packed snow |
| Steel Segment | High-Strength Steel | Supports carbide inserts |
| Rubber Encasing | Vulcanized Rubber | Dampens vibration and allows flex |
| Clamp Bar | Steel | Secures blade segments to plow |
SENTHAI’s Joma blades are compatible with reversible, one-way, wing, and tow plows, offering customized lengths and profiles for various applications.
How Does a Joma Style Blade Work?
The blade’s rubber-encased segments flex along road undulations, creating a squeegee effect for efficient snow removal. Carbide tips cut ice while the rubber absorbs shocks, reducing road wear and operator fatigue.
A thin segment profile improves snow-cutting efficiency, while SENTHAI’s precision bonding via sintering and welding ensures long-lasting performance. Accessories like CurbRunner guards protect edges from curbs, and the adapter blade distributes loads evenly, further extending service life.
What Advantages Do Joma Style Blades Offer?
Joma style blades provide up to three times the wear life of conventional steel edges, reduce salt use by 20–30%, and minimize road damage due to contouring. Reduced vibration ensures safer driving, while sectional replacements lower maintenance costs.
SENTHAI’s bulk supply capability benefits municipal fleets and commercial operations, providing cost-effective, high-performance blades optimized for extreme winter conditions.
Why Are Joma Blades Superior to Traditional Edges?
Joma blades outperform flat steel and full-carbide edges by flexing to match road surfaces, avoiding gouging, and improving snow clearance. Rubber isolation reduces shock loads, protecting plow components and trucks.
Traditional rigid edges create uneven pressure and accelerate wear, requiring more salt. Joma’s articulation distributes force evenly, reducing vibration by approximately 50%. SENTHAI’s factory-direct production allows OEM-customized solutions that surpass generic alternatives.
| Feature | Joma Style | Traditional Steel |
|---|---|---|
| Articulation | Sectional, flexible | Rigid, single piece |
| Wear Life | 2–3x longer | Standard |
| Salt Usage | Reduced 20–30% | Minimal |
| Vibration | Low | High |
| Road Damage | Minimal | Significant |
How Are Joma Style Blades Installed?
Installation is simple and requires minimal tools. Remove the old edge, attach the adapter blade, align and clamp segments, then tighten bolts according to specifications. SENTHAI bolt-on designs eliminate the need for welding and allow one-person installation in under 30 minutes. Post-installation testing ensures proper articulation.
Which Applications Are Best Suited for Joma Style Blades?
These blades excel on highways, rural roads, and concrete or asphalt surfaces with varying contours. They are ideal for high-volume municipal plowing, where minimizing salt usage and maintaining road integrity are priorities. SENTHAI customizes carbide density to match specific road types and plow configurations.
