B2B Guang Yu Badminton Racket – Supplier Overview
Product Overview
Guang Yu badminton rackets are manufactured for bulk supply to sporting goods distributors, OEMs, and institutional buyers. The design focuses on consistent weight distribution, shaft stiffness, and frame geometry that meet international play standards. Each unit is produced in batches with traceable lot numbers to support quality tracking.
Key Technical Specifications
| Parameter | Typical Value | Notes |
|---|---|---|
| Overall Length | 675 mm ± 2 mm | Measured from butt cap to tip |
| Unstrung Weight | 80 g ± 3 g | Includes grip, excludes strings |
| Balance Point | 295 mm ± 5 mm from butt | Even‑balance classification |
| Shaft Flex | Medium (≈ 7.5 mm deflection under 10 N) | Suitable for all‑round play |
| Frame Material | High‑modulus graphite composite | Layered with resin for impact resistance |
Material Composition
The racket frame uses a high‑modulus graphite cloth impregnated with epoxy resin, providing a tensile strength of approximately 4.2 GPa. The shaft incorporates a tapered graphite core reinforced with aramid fibers to dampen vibration. The grip is made of PU‑foam wrapped in a synthetic leather overlay, offering a sweat‑absorbent surface with a durometer of 65 Shore A.
Manufacturing Process
Production begins with lay‑up of pre‑impregnated graphite sheets onto a mandrel, followed by vacuum bagging and curing at 180 °C for 90 minutes. After demolding, shafts are machined to tolerance ± 0.1 mm and assembled with the grip using a solvent‑free adhesive. Each racket undergoes a static load test of 150 N to verify frame integrity before painting.
Performance Characteristics
The even‑balance design yields a swing weight of approximately 85 g·cm², facilitating quick wrist action. Medium shaft flex delivers a rebound efficiency of about 78 % under standard impact conditions. These parameters are validated through drop‑weight testing on a calibrated pendulum rig.
- Consistent shuttle‑cock exit speed variance < 3 % across a batch of 100 units.
- Frame deflection under 50 N load remains within 0.4 mm, indicating high stiffness.
- Grip torque resistance measured at 1.2 Nm before slippage occurs.
Applications in Industrial B2B Context
Distributors purchase these rackets to stock retail chains that require uniform specifications for league play. OEMs integrate the frames into custom‑branded lines where weight and balance must match a reference model. Sports academies order bulk sets to ensure trainees receive equipment with identical feel, reducing variability in training outcomes.
Customization Options
Buyers can request adjustments to weight, balance point, grip size, and cosmetic finish while maintaining the core graphite lay‑up. Customization is executed by altering the lay‑up schedule or selecting alternative grip compounds.
- Weight range: 75 g – 88 g (unstrung) in 1 g increments.
- Balance point: head‑light (260 mm) to head‑heavy (330 mm).
- Grip circumference: 80 mm, 85 mm, 90 mm.
- Finish: matte, gloss, or custom color‑match via pad printing.
Quality Assurance & Inspection
Quality control follows a three‑stage protocol: incoming material verification, in‑process dimensional checks, and final functional testing. Each lot is sampled at a rate of 2 % for weight, balance, and flex measurements. Results are logged against the lot number and supplied with the shipment documentation.
Inspection criteria include: frame crack detection via 10× magnification, adhesive bond strength ≥ 1.5 MPa, and grip adhesion resistance to peeling under 5 N lateral load. Non‑conforming units are segregated and re‑worked or scrapped according to internal defect classification.
Packaging and Logistics
Rackets are packed in corrugated cartons with internal dividers to prevent contact damage. Each carton holds 30 units, weighed approximately 2.5 kg, and is sealed with pressure‑sensitive tape. Cartons are palletized (1.2 m × 1.0 m base) and stretch‑wrapped for stable transport.
Export shipments include a moisture‑absorbent sachet (silica gel, 5 g) per carton to mitigate humidity effects during transit. Standard Incoterms offered are FOB Ningbo or CIF destination port, with lead times typically 20‑25 working days after receipt of purchase order and approved artwork.
Frequently Asked Questions
- Can dimensions be customized?
- Yes, length, weight, and balance point can be adjusted within the ranges specified; tooling changes may affect lead time.
- What information is required before quotation?
- Required details include target quantity, desired weight/balance, grip size, finish type, and preferred packaging.
- What materials are available for the frame?
- Standard is high‑modulus graphite; alternative blends with boron or nanotube reinforcement are available upon request.
- How is quality inspected?
- Inspection includes weight, balance, flex, frame integrity, and bond strength checks as outlined in the quality assurance section.
- What packaging methods are available?
- Standard carton with dividers; optional single‑unit sleeve or bulk‑pack pallet without internal dividers for large OEM orders.
- How are export shipments protected?
- Each carton contains a silica gel sachet and is stretch‑wrapped on pallets; corner boards can be added for extra protection.
- What is the typical production lead time?
- Lead time ranges from 20 to 25 working days after order confirmation, depending on customization complexity.
- How are samples arranged?
- Samples are produced after approval of specifications and shipped via express courier; sample costs are credited against the first bulk order.
