8 Steps to Urtopia Carbon Fiber

1. Weaving and Pre-Impregnation:

We select race-grade Toray T1000 carbon fibers and weave them at various angles based on design needs. Our proprietary resin, enhanced with silane coupling agents, improves wetting and curing. Lab tests show this optimized resin densifies the fabric—boosting strength by 5.7%, reducing weight by 4.3%, and cutting delamination risks, potentially extending lifespan by over 50% for enhanced safety.

2. Cutting and Sorting:

During carbon fabric processing, we employ an advanced automated system that precisely cuts, sorts, and codes the fabric based on input dimensions without manual labor. This system reduces the industry’s typical error rate of 0.6% to 0%, minimizing human error and ensuring consistent quality and performance.

3. Pre-Forming:

In the pre-forming stage, we use CAE (Computer Aided Engineering) and FAE (Finite Element Analysis) to aid the design of lamination. Experienced technicians then follow procedures to attach hundreds of pre-cut carbon fabric pieces onto an EPS inner mold. Our unique stacking design optimizes strength, weight, rigidity, and shock absorption— the essence of our carbon fiber frame. Specially shaped patches reinforce areas with varied stress, ensuring stability under complex loads. Consequently, frames with the same exterior can perform differently due to their stacking design.

4. Molding:

Molding is a key step in forming carbon fiber products. Using high-precision molds and controlled temperatures, the fibers and resin cure perfectly. Unlike traditional splicing, our partner’s exclusive MonolithTM one-piece molding forms the entire frame in one process. This directly half the molding time as instead of 2 or 3 pieces of molds now we only do this once for one frame. Less machine time implies shorter production lead time and lower overall cost.

5. Machining:

The Monolith™ technology offers a dual advantage: cost - effectiveness and remarkable performance. Traditional bike frames require gluing and curing, leaving behind heavy and unappealing junctions, which can also create weak points. In contrast, products made with MonolithTM are crafted in one seamless piece. This not only results in a frame with an elegant shape and smooth surface, but also brings about a significant weight reduction. Frames using this technology are over 11.7% lighter; for example, a road bike frame weighs just 583g without any comprimise on the performance.

6. Comprehensive Reliability Inspection:

Each frame undergoes eight rigorous reliability tests. Our long-term investment in testing equipment and quality control ensures potential issues are identified and resolved during production. We perform comprehensive X-ray inspections to detect subtle defects, such as internal carbon fiber delamination, voids, and tiny foreign inclusions, ensuring the frame’s overall reliability and quality.

7. Painting:

Painting is the final step in our frame production. After thorough cleaning, we apply a primer and bake the frame at a controlled low temperature for proper curing. Then, we add decals and a topcoat, followed by another low-temperature bake to achieve the final finish. This process improves paint adhesion, durability, and overall lifespan, ensuring no quality issues due to carbon fiber’s unique properties.

8. Quality Inspection:

Our factory adheres to ISO9001 and TS16949 standards, using automotive-grade quality controls. After 37 thorough inspections of each frame’s appearance and dimensions, the product is packaged and shipped. This rigorous process enhances reliability and safety, ensuring every consumer can trust our product.
