Carbon Fiber Special-Shaped Parts Manufacturers

Custom Carbon Fiber Special-Shaped Parts, Engineered from Fiber to Finished Component

Jiangyin Dongli New Materials Technology Co., Ltd. is a China-based Carbon Fiber Special-Shaped Parts Manufacturers and one-stop factory. We control the entire value chain—from weaving carbon fiber fabrics and producing prepreg to final molding via autoclave, RTM, RMCP, PCM, WCM, and spraying. This vertical integration lets us deliver non-standard, high-performance components with consistent quality for aerospace, automotive, sports equipment, construction, electronics, and ODM projects.

Our 32,000-square-meter facility includes climate-regulated workshops and 100,000-grade purification zones, ensuring stable material behavior and precise lamination. Whether you need a drone shell, a motorcycle skid plate, or a custom enclosure, we engineer the part around your load case, dimensional tolerances, and production volume.

Our Range of Special-Shaped Parts

We supply both functional and aesthetic components across six application-focused categories. Each category addresses specific mechanical and environmental demands, and we adapt the material system and molding process accordingly.

Engineering and Manufacturing Approach

Every special-shaped part begins with a material selection and a process plan. We use our own carbon fiber fabrics and prepregs—epoxy or cyanate ester—to match the thermal and mechanical demands of your application. For high-temperature or high-stiffness needs, we adjust the fiber areal weight, weave style, and resin system.

Our molding capabilities include:

• Autoclave for aerospace-grade void content and consistent mechanical properties.
• RTM (Resin Transfer Molding) for complex geometries with tight tolerances and good surface finish.
• RMCP / PCM / WCM for high-volume production with rapid cycle times.
• Spray-up for large, lightly loaded parts where cost efficiency is key.

We also operate 315T and 800T hot presses, enabling compression molding of thick or highly contoured components. Our factory equipment includes precision cutting and lay-up stations, ensuring repeatable fiber orientation and dimensional accuracy.

Quality Assurance and Testing

We follow ISO 9001:2015 quality management principles. Each production batch is traceable from raw fiber to finished part. In-process checks include ply orientation, resin content, and cure cycle monitoring. For structural parts, we perform mechanical testing using a 10KN microcomputer-controlled testing machine, verifying tensile, flexural, and impact properties as required.

Our climate-controlled workshops and 100,000-grade purification areas minimize contamination and moisture pickup, which is critical for prepreg handling and final part quality. We also offer non-destructive inspection options for critical applications, such as ultrasonic scanning, to confirm internal integrity.

Customization and ODM Support

We are not limited to standard shapes. Our ODM service covers product design, mold making, prototyping, and mass production. Whether you provide a 3D model, a drawing, or just a concept, our engineering team works with you to optimize the part for manufacturability and performance.

For example, we have produced lightweight carbon fiber delivery boxes and suitcases with hand-laid rivets, demonstrating our ability to combine structural function with premium aesthetics. We also support surface finishing options—matte, gloss, textured, or painted—to meet your brand requirements.

Information We Use to Configure Your Solution

To prepare an accurate quotation and manufacturing plan, we need the following project details:

• Part geometry: 2D drawings, 3D CAD files (STEP/IGES), or physical samples.
• Application and load requirements: static/dynamic loads, impact, pressure, or temperature exposure.
• Dimensional tolerances: critical surfaces and allowable deviations.
• Production volume: prototype, low-volume, or high-volume series.
• Surface finish: cosmetic class, texture, or paint specification.
• Compliance needs: flame retardancy, outgassing, or specific industry standards.

With this information, we define the material system, ply schedule, molding method, and tooling strategy. We then provide a detailed proposal including lead time and payment terms.

Delivery and Logistics

Our factory is located in Jiangyin, Jiangsu Province, about one hour from Shanghai by high-speed rail. We handle domestic and international shipping, with typical production lead times of 20 days for normal volume orders. We offer FOB, CIF, and other incoterms, and we can arrange packaging that protects parts during transit.

For long-term programs, we support scheduled deliveries and consignment stock to reduce your inventory burden.
