Production Process

Quality Guarantee

This equipment is used to test the torsional rigidity and structural stability of badminton racket shafts and frames. It simulates the twisting force generated during actual swinging, hitting and net blocking movements.
Working Principle
Two sets of pneumatic fixtures firmly lock the racket handle and racket head respectively. The air cylinder applies fixed torque to twist the racket body. Sensors record real-time twist angle, rebound data and permanent deformation value after releasing force.
Test Significance
Verify whether the full carbon frame has sufficient anti-twist performance to avoid off-target shots caused by frame distortion during hitting.
Screen unqualified products with soft shafts or loose carbon layers; guarantee stable hitting feedback for 4U–8U ultra-light rackets.
Ensure the racket can withstand long-term swing torsion without permanent bending deformation.

Focused on testing the bending resistance and structural strength of the badminton racket middle shaft, simulating the heavy bending load generated during powerful smashes, hard defensive blocks and accidental shaft compression impacts.
Working Principle
The racket handle is horizontally locked on an adjustable sliding fixture. The precision pressure head slowly presses vertically down onto the middle shaft section. Built-in force sensors record the maximum bearing load, bending deflection and fracture threshold of the shaft in real time.
Test Significance
Verify the rigidity of our full carbon middle shaft, confirm it won't bend excessively or snap under intense hitting force.
Validate the shaft's load capacity matching our 28–35 lbs high tension design, ensuring stable power transmission from handle to racket head.
Standardize strength inspection for all 4U–8U lightweight models to eliminate weak shafts and improve overall racket durability.

Vertical load test for the top and throat of the racket head, simulate the pulling force of high-tension strings and heavy vertical impact from powerful smashes.
Working Principle
The racket is fixed vertically. A circular pressure plate applies uniform vertical pressure on the top arc of the racket head. The machine records deformation curve, elastic recovery performance and breaking load limit.
Test Significance
Verify the frame's bearing capacity under 28–35 lbs high string tension, prevent frame ovalization or fracture after stringing.
Detect the structural strength of the racket head arc and throat, ensure powerful smashes will not cause frame collapse.
Standardize quality inspection standards for all weight specifications (4U to 8U ultra-light rackets) to unify product stability.

Core Performance Advantages

Rich Material Selection For Diversified Demands 
We supply multiple frame materials for customization. Multi-layer solid wood composite rackets feature sensitive ball feeling and stable control, suitable for close-table control players and beginners. Carbon fiber & graphite composite rackets own lightweight structure, strong rigidity and explosive power, delivering fast ball speed for fast attack and loop players. Buyers can select materials according to market positioning and target customer groups.
All-Round Customization Solutions 
Support customized items include silk screen / heat transfer / laser engraved brand logo, frame paint color, surface decorative pattern, racket length, static weight, balance distribution, straight handle / flared handle, max string tension and grip specification. We can develop exclusive new styles according to customer design drafts and realize personalized private label service.
Precise Hot Press Manufacturing Process 
Each layer of timber and carbon material undergoes standardized hot pressing molding. Uniform internal bonding effectively avoids layer separation and deformation under long-time hitting. Strictly controlled weight tolerance ensures consistent hitting performance of each batch of rackets.
Ergonomic Humanized Design 
Optional multiple handle styles, polished smooth surface without burrs. Scientific weight distribution reduces wrist fatigue during long training and matches. Flat smooth frame edge reduces air resistance and optimizes swing fluency.
Wide Application Scenarios 
Suitable for daily skill training, amateur badminton matches, school physical education courses, club team equipment configuration. Perfect for sporting goods retail brands, team uniform customization, corporate promotional gifts and badminton training institutions.
Strict Quality Control & Factory Direct Supply 
All customized rackets pass flatness inspection, elasticity testing and appearance screening before shipment. We provide professional technical communication during pre-production sample confirmation. Flexible MOQ supports small batch trial orders and large-volume bulk wholesale, competitive factory price for long-term cooperation.
