Product Development Process

1 Layup / Pre-molding Process

60mm deep carbon rims

Precision Automated Cutting

Using premium Toray T800 & T1000 carbon prepreg, every layer is precisely cut by automated CNC machinery into exact angles and dimensional profiles to ensure perfect structural alignment.

Multi-Angle Manual Lamination

Skilled technicians lay up carbon sheets in precise directional schedules (0°, 45°, 90°). This optimized schedule maximizes lateral stiffness, impact resistance, and structural strength.

Automated Carbon Roll Pre-cutting

High-quality carbon fiber prepreg rolls are continuously fed and pre-cut with strict material tension control, laying a consistent, zero-defect foundation before manual lamination.

2 Molding Process

High-Precision Mold Preparation & Alignment

Pre-molded rim blanks are carefully aligned in high-strength alloy molds. Strict temperature and pressure monitoring ensures flawless compaction and seamless carbon layer bonding during curing.

Thermal Curing & De-molding Quality Control

Rims undergo controlled hot-press curing under extreme pressure to eliminate air voids. Once de-molded, each rim is rigorously inspected for structural integrity and surface smoothness.

3 Machining

Automated 3D CNC Drilling Multi-axis CNC drilling delivers precise spoke hole angles, preventing nipple binding.
Precision Valve Hole Machining CNC reaming ensures ultra-clean valve holes and smooth inner surfaces.
Drainage Hole Milling Precisely machined water drainage ports allow rapid moisture release during wet riding.
Edge De-burring & Inspection All drilled edges are deburred and optically checked for zero micro-cracks.

4 Painting / Decaling Process

Custom Decaling & Precision Coating

Applied with precision in dust-free conditions, seamlessly integrated under a clear coat for lasting aesthetics.
