The production of carbon fiber watch cases involves several complex steps. Here are the basic procedures for making carbon fiber watch cases:
Material preparation: Select high-quality carbon fiber fabric and resin. The carbon fiber fabric serves as the main structural material for the watch case, while the resin is used to bond the carbon fiber fabric together.
Cutting carbon fiber fabric: Precisely cut the carbon fiber fabric into the desired shapes and sizes according to the design drawings of the watch case.
Mold preparation: Prepare a mold that matches the shape of the watch case. This mold can be made of metal or other rigid materials.
Laying carbon fiber fabric: Gradually place the cut carbon fiber fabric onto the mold, ensuring that each layer is flat and free of bubbles. Depending on the design requirements, multiple layers of carbon fiber fabric may be required.
Resin impregnation: Evenly apply the resin onto the carbon fiber fabric using a brush or roller, ensuring that the resin penetrates into each layer of carbon fiber fabric.
Curing: Place the carbon fiber fabric impregnated with resin into an oven and cure it under certain temperature and pressure conditions. During this process, the resin hardens, securely bonding the carbon fiber fabric together.
Demolding: Once the carbon fiber watch case is fully cured, remove it from the mold.
Post-processing: Perform subsequent processing on the removed watch case, such as grinding and polishing, to make the surface smooth, flat, and conform to the design requirements.
