Support until delivery

DIALEAD Composite can be tailored to your applications and specifications.

  • Design Support
    We meet customer needs by optimal design and material selection of composite.
  • Prototyping / mass production
    We are a unique manufacturer that has a complete production system from carbon fiber to carbon fiber composite products
    We can offer quotations from prototyping to mass-produced items.
  • Prices / quality
    Thanks to ISO-based quality control and production structures, we offer quality, competitive composite products.




The coefficient of thermal expansion can be controlled by optimizing carbon fiber mixing, and can be made to zero, depending on design.
In addition to low thermal expansion, lightweight, and high stiffness, heat sink and other thermal controls can be realized, utilizing the product's property of thermal conductivity only in the orientation of the fiber.
