Best Price Ball Badminton Graphite Racket for Sale
This racket is constructed from high-modulus graphite fiber reinforced with epoxy resin, targeting distributors and sports equipment wholesalers who require consistent performance at competitive pricing. The design focuses on delivering a balanced combination of power transmission and shock absorption suitable for intensive training environments.
Technical Specifications
Typical unstrung weight ranges from 80 to 88 grams depending on layup configuration, measured with a precision balance scale. Overall length is 675 mm with a tolerance of ±2 mm, conforming to international badminton racket standards. The balance point is positioned 285 mm from the handle end, providing a slightly head‑heavy feel that enhances swing momentum.
Stiffness, expressed as RDC (Racket Deflection Constant), falls between 22 and 28 mm/kg, indicating a medium‑flex profile suitable for both offensive and defensive play. Recommended string tension lies between 20 and 28 lbs, with a maximum safe limit of 30 lbs to avoid frame deformation.
Material Composition and Layup
The frame utilizes 40‑ton modulus graphite fibers aligned primarily at 0° and 45° orientations to optimize torsional stability and longitudinal strength. A secondary layer of 24‑ton modulus fibers is woven at 90° to improve impact resistance during shuttle‑cork collisions. The resin system is a low‑viscosity epoxy cured at 180 °C for 90 minutes to achieve a glass transition temperature above 150 °C.
The handle incorporates a polyurethane foam core wrapped with a synthetic leather grip, offering a durometer hardness of 70 ShA for moisture absorption and slip resistance. Grip size options are standardized at G4 (85 mm circumference) with optional G3 and G5 variants available upon request.
Manufacturing Process
Fiber prepregs are cut to precise patterns and placed in a heated compression mold that applies 150 bar pressure during the curing cycle. Post‑curing, the frame undergoes CNC machining to achieve exact beam dimensions and throat geometry before drilling string holes with a tolerance of ±0.1 mm.
Each racket receives a UV‑stable clear coat to protect the graphite surface from abrasion and UV degradation, followed by a 24‑hour conditioning period at 23 °C and 50 % relative humidity to stabilize mechanical properties.
Performance Characteristics
Impact testing shows a peak force transmission of 180 N at the sweet spot, with a vibration decay time of 12 ms, indicating effective damping through the graphite layup. Energy return measured via pendulum rebound yields a coefficient of restitution of 0.78, translating to efficient power conversion during smashes.
Frame deflection under a 50 N load applied at the 3‑and‑9‑o’clock positions averages 2.3 mm, confirming the medium‑flex classification. These metrics allow buyers to predict playing feel and durability under repeated high‑impact cycles.
Typical Applications
- Sports clubs and training academies that require rackets for daily coaching sessions and member usage.
- Retail distributors seeking a cost‑effective graphite model for mid‑tier product lines.
- OEM suppliers who integrate the racket into branded kits for school sports programs.
Model Comparison
| Model | Weight (g) | Balance Point (mm from handle) | Stiffness (RDC, mm/kg) | Recommended Tension (lb) | Price Range (USD) |
|---|---|---|---|---|---|
| Standard | 84 | 285 | 25 | 22‑26 | 18‑22 |
| Lightweight | 80 | 280 | 22 | 20‑24 | 20‑24 |
| Power | 88 | 290 | 28 | 24‑28 | 22‑26 |
Quality Control and Testing
Every production lot undergoes dimensional inspection using a coordinate measuring machine with a repeatability of ±0.02 mm. Flexural stiffness is verified on a three‑point bend fixture calibrated to NIST traceable standards.
Impact resistance is assessed via a drop‑weight tester delivering 2 J energy to the frame throat; acceptable units show no visible cracking or delamination. Final visual inspection checks for coating uniformity and grip adhesion under 100 % humidity exposure for 48 hours.
Customization Options
- Grip size: G3, G4, G5 (optional over‑wrap thicknesses available).
- Frame color: matte black, glossy white, or custom Pantone match upon request.
- String pattern: standard 16×19 or alternative 18×20 for increased control.
- Weight tuning: insertion of tungsten weights in the handle shaft to shift balance point by ±5 mm.
Frequently Asked Questions
Can the racket specifications be adjusted for a specific order?
Yes, weight, balance point, and stiffness can be tailored by modifying the graphite layup and resin content; detailed requirements should be submitted during the quotation phase.
What information is needed to obtain a formal quote?
Provide desired quantity, target delivery date, any customization requests (grip size, color, weight tuning), and preferred Incoterms; a technical drawing is optional but helpful for OEM projects.
How is product consistency ensured across large batches?
Statistical process control monitors key parameters such as fiber weight, resin viscosity, and cure temperature; control charts are maintained and available for review upon request.
