Mold Preparation
High-quality molds are essential for shaping carbon fiber products. We craft molds using precise techniques, ensuring they are smooth, durable, and suitable for repeated use. Proper mold preparation guarantees accurate product dimensions and flawless surfaces.
Material Preparation
Only premium-grade carbon fiber materials are selected to ensure top performance. These materials are pre-inspected and prepared to meet the specifications of each project, setting the stage for reliability and durability.
Cutting Prepreg
Prepreg sheets (pre-impregnated carbon fiber) are meticulously cut to the required size and shape. Using precision tools, this step ensures minimal waste and uniformity, preparing the materials for perfect alignment during layup.
Layup
In this step, layers of carbon fiber are strategically arranged in the mold according to design specifications. Proper layering is critical for achieving desired mechanical properties and structural integrity in the final product.
Forming
Under controlled heat and pressure, the layered material is cured and formed into its intended shape. This process bonds the fibers and resin, creating a strong and lightweight component.
Demolding
After forming, the product is carefully removed from the mold. Special care is taken to prevent any damage or deformation, preserving the precision achieved in earlier steps.
Blank Forming Check
A thorough inspection is conducted to verify the dimensions, structure, and overall quality of the freshly formed blank. This ensures there are no defects before proceeding to the next stage.
Trimming and Machining
The product edges are trimmed, and machining is performed to achieve precise shapes and finishes. This process ensures that the component meets exact specifications for its intended application.
Sanding
Sanding smoothens the product’s surface, preparing it for a flawless paint finish. It removes imperfections and creates an even texture, enhancing the visual and tactile quality.
Painting
This step adds protective coatings and a customized appearance. Advanced techniques and durable paints ensure the final product withstands environmental factors while looking polished and professional.
Printing
Logos, graphics, or custom designs are applied to the product using high-precision printing techniques. This step enhances branding and adds unique aesthetic appeal.
Assembling
