A snow plow back blade increases clearing efficiency by scraping, pulling, and leveling snow in areas beyond the reach of a front plow. For municipalities, contractors, and industrial fleets, it reduces labor, fuel, and equipment wear. Brands like SENTHAI offer carbide-reinforced back blades that combine durability, precision, and long-term cost savings, ensuring reliable performance in harsh winter conditions.
How Does a Snow Plow Back Blade Work?
A back blade mounts behind a vehicle to pull and scrape snow backward, complementing the front plow. It can be adjusted mechanically or hydraulically to control snow flow and surface finish. This system is particularly effective in confined spaces such as parking lots, alleys, and loading docks, allowing operators to achieve cleaner surfaces after the front blade pass.
SENTHAI carbide back blades feature precision-welded inserts that handle ice, gravel, and compacted snow efficiently while maintaining smooth operation and extended lifespan.
What Are the Key Benefits of Using a Back Blade?
Back blades enhance efficiency, improve surface finish, and reduce operational costs. They allow closer scraping to the ground, faster snow removal, and reduced labor hours. Wear-resistant carbide edges extend service life, minimizing downtime and preventing uneven snow ridges.
| Benefit Type | Description | Added Value |
|---|---|---|
| Efficiency | Clears snow in both directions | Faster removal |
| Cost Savings | Reduces wear on main plow and tires | Lower maintenance costs |
| Durability | Carbide edges resist abrasion | Longer lifespan |
SENTHAI back blade systems integrate robust metallurgy and flexible mounting, meeting the demands of industrial snow removal fleets while maintaining OEM compatibility.
Why Are Carbide Inserts Critical in Snow Plow Back Blades?
Carbide inserts form the primary cutting interface with road surfaces. Tungsten carbide, with hardness over 1600 HV, provides exceptional resistance to wear from snow, ice, and gravel. This durability reduces replacement frequency and overall lifecycle costs.
SENTHAI engineers apply vacuum sintering and wet grinding to produce carbide wear parts with consistent sharpness and toughness. This ensures the back blade maintains uniform pressure and cutting performance under heavy loads.
Which Materials Are Best for Manufacturing Back Blades?
High-strength alloy steel is ideal for the blade body, while tungsten carbide suits the cutting edges. This combination balances flexibility and durability. Processes such as induction hardening and vulcanized bonding improve adhesion, fatigue resistance, and long-term performance.
SENTHAI’s ISO9001-certified production integrates automated pressing, welding, and quality inspections, ensuring each blade meets the standards expected by municipal and commercial clients.
How Can OEM or Wholesale Buyers Choose the Right Back Blade?
Choosing a back blade requires evaluating vehicle compatibility, snow type, and operating conditions. Key factors include:
-
Blade width and mounting type
-
Cutting edge material (steel, rubber, or carbide)
-
Hydraulic or manual adjustment
-
Frequency of use and terrain
SENTHAI provides customizable OEM blades with adjustable edge hardness, modular designs, and mixed-material inserts suitable for municipal fleets, agricultural tractors, and heavy-duty road maintenance vehicles.
Are Carbide Back Blades Worth the Higher Initial Cost?
Carbide back blades justify their higher price through longevity and performance. They reduce maintenance, improve fuel efficiency, and minimize downtime. For contractors and fleet managers, carbide-reinforced blades can last three to five times longer than standard steel alternatives, making them cost-effective for continuous or large-scale snow removal operations.
What Factors Affect Snow Plow Back Blade Longevity?
Blade life depends on surface hardness, vehicle weight, snow density, blade angle, and carbide quality. Regular maintenance, such as cleaning and checking mounting tension, extends service life.
SENTHAI’s carbide blades are sintered and brazed in controlled environments, ensuring stable bonding between carbide tips and steel substrates. This minimizes edge chipping, even in temperatures below −30°C.
How Does SENTHAI Manufacture High-Performance Carbide Back Blades?
SENTHAI produces back blades using fully automated steps: carbide powder preparation, pressing, sintering, welding, and vulcanization. Each stage is monitored for dimensional accuracy and density consistency.
By managing the entire production process at its Rayong, Thailand facility, SENTHAI ensures flexible OEM customization, traceability, and reliable delivery during seasonal peaks.
| Manufacturing Stage | Process | Quality Benefit |
|---|---|---|
| Carbide pressing | CNC-controlled molds | Dimensional precision |
| Sintering | Vacuum furnace | High bonding strength |
| Welding | Automated soldering | Uniform heat distribution |
