Step 1-Carbon Prepreg Production
We purchase different kinds of carbon fibers from Toray Japan.According to the rims requirements,we produce the optimal epoxy resin.The carbon prepregs are carbon fibers saturated with epoxy resin through the machines and then kept in optimal condition through refrigeration at -5℃: a stable temperature for the resin.
Step 2- Cutting Carbon Sheets
Firstly we prepare the prepreg carbon fiber（pre-impregnated with custom proprietary high TG resin).
According to the production schedule,we need to select the necessary carbon sheets.Carbon fiber sheets are cut into the desired angles of 0°, ±45°,±30°, and ±90°. The carbon fibers are precisely machine-cut into pieces.
Step 3-Lamination Preparation
Our well trained staffs will prepare the different multiple layers of high-tensile carbon sheets,high modulus carbon reinforcement strips for the rim layup process.This step is very import to speed up the carbon rim production.Lamination prepares the different parts of the rim with the carbon sheets which allows us to arrange the product more easily.We have the unique innovation in the carbon sheets lamination which can balance the rim weight,durability,rigidity better.This innovation keep us stand out from many manufacturers.
Step 4-Rim Layup
The premold eliminate the risk of fiber moving during layup transfer. We adopt two-in-one molds for manfacturing to make mold more precise.We have the unique patented molds for rim layup and with the custom air bags that match the inner shape of each specific model rim.These custom made bags ensure that the compression is equal on the entire inner surface of the rim during the molding process.Our layup technicians hand lay the fabric layers from the outer to the inner, constructing the rim body as well as fine details like bead hook and nipple reinforcement. After each overlap, we smooth the prepregs to ensure there are no wrinkles, fiber fractures, or air bubbles. When layups are finished, the two parts of the premold are merge into one mold and prepared for the next process.The technicians must check rim weight before the molding process.
Step 5-Curing And Forming
During the molding process,heat and pressure are accurately controlled and monitored in the composite curing ovens.The rims will be formed under the temperature controlled molding heating curing equipments.
Step 6-Quality Check
All rims are 100% inspected and visual checked.
Step 7-CNC Machining
After quality inspection,the rims are moved to CNC machining workshop to drill holes.We use aviation-grade CNC drills with drill bits specifically designed for drilling through advanced composites.All rims are drilled at a proper angle and good condition.
Step 8-Quality Check
All rims are 100% inspected and visual checked.
Step 9-Refinement
After quality inspection,the rims will be tansferred to sanding worshop to be sanded.After quality inspection,the rims will be tansferred to sanding worshop to be sanded.Details determine success or failure.We focus on the rim details,we have special details treatment workshop to handle the details.
Step 10-Quality Check
All rims are 100% inspected and visual checked.
Step 11-Painting
The ultralight carbon rims are paintless but the traditional rims should be sent to the painting workshop for a glossy, matte, or any custom finish.
Step 12-Waterslide Decals & Laser Carving
After painting,some rims required waterslide cecals and some Rims required laser logo.We recommend laser carving logo which is brief and environmental.
Step 13-Quality Check
All rims are 100% inspected and visual checked.
Step 14-Packing
All the rims in good condition will be packed carefull and will be took pictures for customers double confirmation if needed.If the customers order the wheels ans then go to next process.
Rims will be tested including UCI vertical impact test,additional impact,stiffness,trueness,longevity test,frequency torque fatigue test and tire pressures test during the manufacturing.Learn More>>
Step 15-Wheels Assembly
Amoy Wheels will be handbuilt by our professional technicians.Wheels are stress-relieved 4 to 5 times before packing so they’re ready to be rode.
Step 16-Packing
All the wheels in good condition will be packed carefull and will be took pictures for customers double confirmation if needed.
Step 17-Shipping
We provide several shipping options depending on your choose(time-efficient or economical). If your order was shipped, tracking number will be provided to you as soon as possible.
