Soutien à l'ingénierie
Our engineer team is composed of technicians who have been focusing on carbon fiber and composite materials for a long time. The core members have more than 10 years of experience in the industry and are familiar with the structural design, material selection and manufacturing process control in different application scenarios.
They not only understand the drawings, but also understand the force, weight, strength and consistency requirements of the products in actual use. At the early stage of the project, our engineers will participate in the manufacturability assessment (DFM), take the initiative to point out the potential risks, and propose more stable and mass-producible solutions without changing the core functions.
Whether it’s technical details, drawing validation, or tolerance, process and lot stability issues, you get clear, timely, actionable feedback.
Quality Control & Repeatability
Our quality system is built around process control and repeatability
Customer Voice
Why Customers Choose to Stay with Us
We sent STP files and got useful feedback instead of just a price. That saved us time during prototyping and scaling.
Daniel Wright
Operations Manager from Australia
We’ve reordered the same parts multiple times and the dimensions and finish stayed stable. That’s important for our assembly line.
Michael Anderson
Engineering Manager from USA
No overpromising, no sales talk. When something wasn’t ideal, they explained the trade-offs and suggested alternatives.
Hiroshi Tanaka
Supplier Development from Japan
They’re not focused on one-off parts. Once our model was confirmed, production was predictable and smooth.
Thomas Müller
Technical Manager from Germany
You can tell they control their own processes. Questions about tolerances and tooling were answered directly by people who actually make the parts.
Jan de Vries
Supply Chain Manager from Netherlands
We started with samples and moved to repeat orders. Lead times and quality stayed aligned with what was agreed at the beginning.
Ahmed Al Mansoori
Project Manager from United Arab Emirates
Our Mission
Our mission is to be our customers’ trusted carbon fiber parts manufacturing partner.
We specialize in reducing manufacturing risk, guaranteeing quality consistency, and supporting long-term project stability.
In every project, we set the standard for rigor and accountability to create predictable, replicable manufacturing results for our customers.
Carl Wang
Vice President of Sales
I come from a manufacturing background and have spent my career working closely with composite materials, production processes, and industrial supply chains. Before founding the company, I was directly involved in material selection, process optimization, and supplier coordination for carbon fiber and composite components across multiple application scenarios.
My focus has always been practical: how materials perform in real projects, how production consistency is maintained at scale, and how procurement risks can be reduced for long-term partners. I believe carbon fiber is not a “premium material by default,” but a technical solution that must be applied correctly, manufactured consistently, and delivered with clear engineering accountability.
Today, my role is to ensure that our carbon fiber sheets are produced with stable processes, realistic specifications, and transparent communication—so our customers can make confident decisions for project-based sourcing, batch procurement, and OEM collaboration.
