Guang Yu Badminton Racket – B2B Manufacturing Overview

Guang Yu operates a dedicated production facility in Guangdong Province that supplies badminton rackets to international OEMs, sports‑goods distributors, and private‑label brands. The factory focuses on volume‑consistent output while maintaining tight tolerances on weight, balance, and flex characteristics required for competitive play.

Frame and Shaft Materials

The racket frame is built from high‑modulus graphite prepreg with a tensile modulus typically ranging from 230 to 260 GPa, which contributes to a lightweight yet stiff structure. The shaft uses a combination of graphite and nano‑enhanced resin, achieving a flex modulus around 180 GPa and a density near 1.55 g/cm³. These material choices allow the finished racket to weigh between 85 and 90 grams when unstrung.

Racket Construction Details

Construction follows a symmetrical layup where the frame undergoes a 2‑step molding process: first a low‑pressure bladder mold shapes the head, then a high‑pressure press consolidates the shaft and handle. Grommet holes are precision‑drilled to 0.8 mm diameter, allowing string tension up to 28 lb without deformation. The handle incorporates a tapered polyurethane grip core with a diameter of 22 mm at the base, reducing vibration transmission.

Typical Specifications

Production Process Overview

The process begins with cutting prepreg sheets to precise patterns, followed by automated layup on mandrels. After layup, the rackets enter a compression mold where they are cured at 180 °C for 90 seconds under 150 bar pressure. Post‑curing, excess flash is removed by CNC machining, and the shafts are ground to final diameter tolerances of ±0.02 mm. A UV‑cured clear coat is applied before pad‑printing of logos and final grip installation.

Inspection and Testing

Each batch undergoes inline weight measurement using a load cell with 0.01 g resolution, and balance is verified on a pivot‑beam apparatus. Swing weight is measured via a pendulum method, targeting a range of 78‑82 kg·cm². Torsional stiffness is assessed by twisting the handle 5° and measuring torque, ensuring values stay within 1.2‑1.5 Nm/°. Impact resistance is checked by dropping a 0.5 kg steel ball from 1 m onto the frame; no cracks are accepted.

Industrial Applications

Distributors sourcing rackets for retail chains benefit from Guang Yu’s ability to produce consistent batches that meet international tournament specifications, reducing the risk of non‑compliant returns. OEMs that private‑label sports equipment rely on the factory’s tight tolerance control to maintain brand performance claims across multiple markets. Additionally, the facility supports short‑run custom runs for promotional events, allowing rapid turnaround without retooling the entire line.

Customization Options

Guang Yu offers several adjustable parameters that can be tuned per project requirements.

• Weight adjustment: ±5 g via changes in layup thickness or shaft reinforcement.
• Balance shift: move the balance point 5‑15 mm toward head or handle by altering resin distribution.
• Flex modification: select different graphite modulus or add thermoplastic inserts to achieve stiff, medium, or flexible feel.
• Grip size: standard (G2), small (G1), large (G3) with optional over‑wrap thickness.
• Finish: matte, gloss, or UV‑printed graphics; logo placement via pad‑print or laser etching.

Frequently Asked Questions

Can dimensions be customized? Yes, head width, shaft length, and grip circumference can be adjusted within standard mold limits; new molds are available for major changes.

What information is required before quotation? Provide target weight, balance point, preferred flex, quantity, and any branding or packaging specifications.

How is quality inspected? Inline weight, balance, swing weight, torsional stiffness, and impact tests are performed on every lot; final audit includes visual inspection and adhesion testing.

What packaging methods are available? Rackets are packed in individual foam sleeves, then placed in corrugated cartons with corner protectors; palletization and heat‑shrink wrapping are offered for export.
