Carbon Fiber Manufacturing Capabilities

Unlike carbon fiber suppliers that outsource key steps, we run autoclave prepreg, vacuum infusion, RTM and compression molding in-house — from prototype to mass production.

Autoclave prepreg carbon fiber parts

Autoclave Prepreg

20 autoclaves for high-definition dry carbon where finish and strength both matter.

Compression molding and forged carbon

Compression & Forged

15 presses for consistent, high-volume compression and forged carbon.

CNC mold machining and composite testing

CNC Tooling & Testing

80 CNC machines for in-house tooling, plus vacuum, coating and strength testing.

In-house Toray carbon fiber weaving

In-House Weaving

Authorized Toray filament supply, woven in-house for consistent material and signature patterns.

Robotic spray coating and curing ovens

Robotic Spray Coating

Robotic coating with controlled curing ovens for a clean, consistent finish.

Carbon fiber bonding and assembly

Bonding & Assembly

Engineered bonding and assembly for complex components — built for strength and finish.

Get to Know JCSPORTLINE

Few carbon fiber manufacturers control every step in-house. With R&D making up over 15% of our team, our plants and global engineers keep your project on time, at any scale.

01 · Re-Innovation

New Technology, Ready for Production

We integrate new materials, processes, and technologies into existing designs. Not experimental concepts — but scalable, manufacturable improvements. Innovation that performs in real products, not just prototypes.

02 · Re-Engineering

Engineering Rebuilt Around Carbon Fiber

Carbon fiber is not a replacement — it’s a new engineering foundation. Structures, load paths, and processes are redesigned from the ground up. Built for strength, consistency, and reliable mass production.

03 · Differentiation

Designed for Long-Term Brand Value

True differentiation goes beyond features or short-term trends. We create defensible product identities through engineering and materials. Positioning your brand for sustainable, premium growth.

Industries We Serve

Engineered carbon for every demanding application.

We partner with professionals across diverse industries to develop custom carbon fiber parts — with the engineering depth that sets us apart from typical carbon fiber companies.

6 Stages · One Team

From Concept to Mass Production

Most carbon fiber manufacturers handle one stage — we manage all six. Starting with a detailed feasibility report, every stage is carefully managed to meet your deadlines.

  1. 01

    Concept & Feasibility

    Send a sketch, drawing, sample or spec. We assess function, loads, finish, volume and budget, then recommend the right process.

    Feasibility report in 3–7 days
  2. 02

    Engineering & Materials

    3D scanning and reverse engineering where needed, CAD and layup design, material selection, FEA / CFD simulation and DFM.

    Production-ready CAD & layup plan
  3. 03

    Tooling

    Molds and fixtures CNC-machined in-house — matched to the process and volume, with tight control on critical interfaces.

    Steel, aluminum or composite molds
  4. 04

    Prototyping

    First samples built with the production-intent process — autoclave prepreg, compression molding or vacuum infusion / RTM.

    Functional samples in 7–15 days
  5. 05

    Testing & Validation

    Dimensional inspection, mechanical and lab testing, and fit-and-function trials in the real application — then your sign-off.

    Dimensional, fatigue, tensile & 2,000-hr xenon aging tests
  6. 06

    Mass Production & Delivery

    Scaled across our 4 plants under ISO / IATF 16949 quality control, with PLM and MES tracking through to global shipping.

    Consistent batch delivery
58 days from concept to sample. See the 58-day workflow
