Project Overview
A power tool manufacturer required quieter gear assemblies for their professional tools. The project demanded noise reduction, wear resistance, and equivalent strength to metal.
Challenge
- Noise Reduction: 40% reduction target for user comfort
- Strength: Equivalent to metal gears
- Wear Resistance: Long service life under load
- Temperature: Motor heat and friction heating
- Cost: Competitive with metal alternative
Solution
Material & Design
- PA6 (Nylon 6) with optimized formulation
- Optimized gear tooth profiles for quiet operation
- Integrated lubrication channels
- Precision molding for smooth operation
Testing & Validation
- Noise testing under operating conditions
- Wear testing for durability
- Torque capacity validation
- Temperature resistance testing
Results
| Metric | Target | Achieved |
|---|---|---|
| Noise Reduction | 35% | 40% |
| Durability | Equivalent to metal | Exceeded |
| Annual Volume | 200K units | 500K+ units |
| User Satisfaction | 85% | 95% |
| Cost | Equal to metal | 15% lower |
Customer Testimonial
“CoreLMould’s nylon gear assemblies are fantastic. 40% quieter than metal, same durability, and lower cost. Our customers love the reduced noise.”
