Amid rising demands for safety and durability in commercial gym equipment, domestic sports brand VANBO has officially launched its professional ARK Series dumbbells. Featuring polyurethane coating technology, an innovative octagonal anti-roll structure, and versatile design, this product meets the upgrade needs of mid-to-high-end gym strength equipment. Initial orders have covered over 20 fitness facilities across Asia.
Polyurethane Armor: 12mm Thick Coating Sets Industry Protection Benchmark
Addressing common issues like cracking and metal impact noise in traditional rubber-coated dumbbells, the ARK Series adopts a triple-layer composite structure:
Core Layer: Solid #45 forged steel inner core with high-frequency quenching treatment
Buffer Layer: Chamfered steel core edges effectively prevent surface rubber cracking
Protective Layer: 12mm thickened polyurethane coating passes -30°C freeze/70°C bake cycle tests with no deformation or cracking
Third-party 100,000 drop tests confirm coating integrity.
Octagonal Revolution: From Training Tool to Safety System
The groundbreaking octagonal head design integrates four innovations:
1. Anti-Roll Structure: Eight 120° concave surfaces create self-locking effect, auto-repositioning at 30° tilt
2. Push-Up Mode: R15mm rounded corners eliminate palm pressure marks
3. Floor Protection: Polyurethane edges extend 12mm beyond steel core, preventing floor scratches
4. Visual Identification: Centralized weight markings at 2.5kg increments, recognizable from 2 meters
Ergonomic Handle: Electroplating Unlocks Ultimate Grip
Handle manufacturing features five precision stages:
1. Base Material: Precision-turned 40Cr alloy steel
2. Plating: Triple-layer composite plating (copper + nickel + hard chrome)
3. Knurling: 0.6mm diamond pattern with double-spiral grooves increases friction by 50%
4. Dimensions: 151mm length fits all hand sizes; anti-slip flanges prevent slipping
5. Balance: <1.5% center-of-gravity deviation across 2.5-50kg range ensures stable swing trajectory
High-intensity testing (100 swings/minute) shows only temperature rise with no peeling.
Commercial Adaptation: Hardware Upgrade to Operational Efficiency
ARK Series aligns with gym operational needs:
Space Efficiency: Octagonal design reduces equipment spacing to 40cm, increasing space utilization by 35%
Maintenance: High-quality polyurethane resists stretching/aging with <10% fading in 5 years
User Experience: Graded handle diameters (2.5-20kg: 32mm; 22.5-50kg: 32mm)
Gym trials show equipment reset time reduced by 66% and trainer efficiency increased by 22%.
Manufacturing Excellence: Baopeng Factory Forges Quality Assurance
Produced in Baopeng Factory's 100,000-class cleanroom with stringent QC:
1. Material Inspection: EU REACH-certified polyurethane
2. Process Control: Injection molding (±2% tolerance) + automated plating lines
3. Load Testing: Simulates 3x self-weight impact
KUKA robotic welding stations maintain <3% defect rate in critical processes.
Customization Activates Global Markets
Options include:
OEM: Pantone color customization, laser logos, weight markings
ODM: Special weights (MOQ: 200 pairs)
From anti-roll engineering to noise reduction, VANBO ARK Series is redefining commercial dumbbell value. As the brand's technical director states: "When equipment becomes an extension of fitness, every curve should embody the synergy of safety and efficiency."
