Racket OEM Sample Prototyping Turnaround, QC Calibration & Courier Matrix
Every physical badminton, padel, tennis, and squash sample dispatched from our Hangzhou Fuyang facility undergoes pre-shipment digital calibration for static weight, balance point, shaft flex, and frame torsion, accompanied by a serialized QC inspection card.
Racket OEM Sample Types & Turnaround Schedule| Sample Tier | Configuration Scope | Factory Prep Time | Air Courier Transit |
|---|
| Open-Mold Stock Evaluation Sample | Verify carbon layup, frame geometry, EVA core density & on-court hitting feel | 48–72 hours | 3–5 business days (DHL / FedEx / UPS) |
| Custom Paint & Water-Slide Decal Prototype | Custom Pantone spray, matte/gloss/chameleon finish, water decals & laser butt cap | 7–10 business days | 3–5 business days |
| Custom 3D Mold Engineering Sample (T1) | Proprietary P20/718H steel cavity CNC milling + custom carbon prepreg layup schedule | 25–35 days (mold + T1) | 3–5 business days |
Pre-Shipment Sample Calibration & Tolerance Checklist| Calibration Metric | Lab Instrument | Target Tolerance |
|---|
| Static Weight & Balance Point | 0.1g Digital Scale & Laser Fulcrum Beam | ±1.5g (Badminton) / ±3.0g (Padel) / ±2.0mm BP |
| Shaft Flex & Frame Torsion | Static Cantilever Deflection & Torque Rig | ±0.2mm flex deflection / ≤ 3.5° torsion angle |
| High-Tension Stringing Overload | 6-Point Constant-Pull Pneumatic Stringer | +20% over rated tension (up to 35 LBS) with zero frame ovalization |
