Joma Style blades outperform traditional steel through tungsten carbide inserts brazed into cast steel segments, encased in rubber for superior flexibility and vibration absorption. This design delivers significantly extended lifespan, less noise, less vibration, and precision fit that protects road surfaces while reducing downtime and maintenance costs.

What Is the Core Design Difference Between Joma Style and Steel Blades?
Joma Style blades feature tungsten carbide inserts brazed into cast steel segments in a horse shoe design, encased in an ultra-low-temperature-resistant rubber shell. Traditional steel blades use a rigid solid steel cutting edge without carbide or rubber dampening. The rubber casing flexes to conform to road contours, preventing chatter and lateral vibration during impact-heavy plowing.
SENTHAI manufactures these 100% in Thailand, using proprietary vacuum sintering for uniform grain size in carbide inserts, ensuring consistent performance across every blade.
Why Do Joma Style Blades Last Significantly Longer Than Steel?
Joma Style blades achieve significantly extended lifespan versus standard steel cutting edges due to micro-grain tungsten carbide’s superior hardness and wear resistance. SENTHAI’s full in-house production—from raw material powder through wet grinding, pressing, sintering, welding, and vulcanization—ensures excellent bonding strength. This reduces replacement frequency, costs, and downtime compared to steel.
| Component | Size (Imperial) | Size (Metric) | Weight |
|---|---|---|---|
| 4-foot snow plow blade | 48″ × 6″ × 7/8″ | 1219mm × 152mm × 23mm | 17.5 kg |
| 3-foot snow plow blade | 36″ × 6″ × 7/8″ | 914mm × 152mm × 23mm | 13.1 kg |
| Cast steel segment | 11.22″ × 5″ × 3/4″ | 285mm × 127mm × 19mm | 3.5 kg |
| Carbide insert | 1″ × 0.95″ × 0.32″ | 25.9mm × 24.25mm × 8.16mm | 70 g |
How Do Joma Style Blades Reduce Noise and Vibration Compared to Steel?
The rubber encasement in Joma Style blades absorbs high-frequency impact vibrations, achieving less noise and less vibration than rigid steel blades. This protects plow equipment, improves operator comfort, and extends equipment lifespan. Reduced vibration also minimizes damage to highway lane markings and road surfaces, potentially requiring less salt or sand.
| Metric | Joma Style Blades | Traditional Steel Blades |
|---|---|---|
| Noise Level | Less noise, reduced vibration | High vibration and chatter |
| Road Surface Damage | Minimal—flexes to contour | Frequent marking and wear |
| Operator Comfort | Reduced fatigue | High vibration stress |
| Equipment Wear | Lower component stress | Accelerated from chatter |
| Maintenance Downtime | Fewer changes | Frequent replacements |
