Custom Professional Badminton Racket – Wholesale Pricing Overview

The racket frame is constructed from high-modulus carbon fiber with a tensile strength exceeding 4.5 GPa, providing a stiffness-to-weight ratio suitable for rapid swing speeds above 130 km/h. This configuration reduces frame deformation during impact, maintaining consistent string bed response across a 0.6 mm tolerance.

Design and Performance Characteristics

The head shape follows an isometric profile with a 22 mm width at the 3‑ and 9‑o’clock positions, enlarging the sweet spot by approximately 12 % compared to conventional oval frames. Aerodynamic drag coefficient measured in wind tunnel tests is 0.28 Cd, facilitating quicker recovery between strokes.

String tension range is specified between 20 lb and 30 lb, with a recommended baseline of 24 lb for optimal power‑control balance. The grommet system uses low-friction nylon inserts, limiting string abrasion and extending usable life by roughly 300 hours of play.

Material Selection and Structural Properties

The shaft incorporates a 40 % graphite and 60 % resin composite layup, oriented at ±45° to enhance torsional rigidity while preserving a flex point at 200 mm from the handle. This layout yields a flexural modulus of 120 GPa, translating to a measured deflection of 2.1 mm under a 10 N load.

The handle core is made from polyurethane foam with a density of 0.25 g/cm³, over‑wrapped with a synthetic leather grip featuring a micro‑perforation pattern for moisture management. Grip circumference options are 86 mm, 90 mm, and 94 mm to accommodate varying hand sizes.

Customization Options for OEM Orders

• Frame length adjustable from 665 mm to 680 mm in 5 mm increments.
• Head weight configurable between 85 g and 95 g via internal weighting inserts.
• String pattern selection: 16×19, 18×20, or 20×21.
• Cosmetic finishes: matte, gloss, or UV‑printed graphics with Pantone‑matched colors.

Manufacturing Process and Tolerances

Frames are produced using automated filament winding followed by compression molding at 180 °C and 150 bar pressure, ensuring uniform resin cure and minimal void content (<0.5 %). Post‑milling CNC machining achieves dimensional tolerances of ±0.1 mm on critical interfaces.

Each racket undergoes a dynamic balance test on a computerized swing analyzer, targeting a balance point within 285 mm ± 2 mm from the handle butt for head‑light models and 300 mm ± 2 mm for even‑balance variants.

Quality Assurance and Testing Protocols

Inspection includes ultrasonic scanning for internal delamination, with acceptance criteria set at <0.2 mm defect depth. Surface finish is evaluated using a gloss meter; gloss units must remain within 45 ± 5 for matte finishes and 80 ± 5 for gloss finishes.

Fatigue testing simulates 5 000 shuttle impacts at 35 m/s; rackets must retain >90 % of initial stiffness after the cycle. Results are recorded and available upon request for audit purposes.

Typical Applications in Professional and Training Environments

The racket’s low swing weight (approximately 78 g) and high repower index make it suitable for singles players requiring rapid net exchanges and precise placement. Doubles players benefit from the stable head‑light balance, which facilitates quick defensive drives and net kills.

Training centers often select the 90 mm grip variant paired with a 19 mm string gauge to enhance durability during intensive multi‑session use, reducing replacement frequency by an estimated 20 %.

Wholesale Pricing Structure and Lead Times

Pricing reflects FOB Shanghai terms; freight, insurance, and customs duties are additional. Sample units are available at a nominal cost, credited against the first order upon approval.

Frequently Asked Questions

Can dimensions be customized beyond the listed ranges? Yes, frame length and head width adjustments are possible upon submission of detailed CAD drawings; additional tooling fees may apply.

What information is required before quotation? We need the desired quantity, grip size, string tension, head weight target, and any cosmetic specifications (color, logo placement).

What materials are available for the shaft? Standard is a graphite‑resin composite; alternative basalt‑fiber reinforcement can be supplied for increased damping, with a corresponding price adjustment.

How is quality inspected? Each batch undergoes ultrasonic internal defect scanning, dynamic balance verification, and fatigue impact testing as described above.

What packaging methods are available? Rackets are packed in individual foam sleeves, placed in corrugated cartons of 10 units each, with optional palletization for containerized shipments.

How are export shipments protected? Cartons are strapped and corner‑protected; moisture‑barrier liners are included for humid climates, and tracking numbers are provided upon dispatch.

What is the typical production lead time? Lead times vary with order size as shown in the table; rush orders can be accommodated with a surcharge.

How are samples arranged? Sample requests are processed within 48 hours; shipping costs are prepaid and reimbursed upon placement of a qualifying wholesale order.
