The production process of enamel cufflinks is a complex and delicate process that covers multiple steps, each of which requires a high degree of professional skills and rigorous operation to ensure the quality and beauty of the final product. In summary, enamel cufflinks are first made of metal, and then coated with colored silicon enamel, which is heated to 1600 degrees Celsius to complete the production. The following is Yuheng’s detailed description of the production process of enamel cufflinks:

• 1. Production of metal base

The production of enamel cufflinks starts with the design and processing of the metal base. Usually materials such as brass, stainless steel or silver are used as the base. These metals are not only strong and durable, but also perfectly combined with enamel. At this stage, the designer will perform precise metal cutting and grinding according to the final shape and pattern of the cufflinks to ensure that the surface of the metal base is flat and suitable for coating enamel. This process requires the use of advanced CNC cutting machines or laser cutting technology to ensure the accuracy of size and consistency of shape.

• 2. Enamel coating

After the metal base is completed, the enamel coating process comes next. Enamel is a material made of fine colored silicon powder. These silicon powders are carefully screened and blended to form different colors and textures, giving enamel cufflinks a rich visual effect. During the coating process, craftsmen use special tools to evenly coat the enamel powder on the metal surface. In order to ensure the saturation and uniformity of the color, multiple coatings are usually performed, and careful inspection is required after each coating to avoid bubbles and unevenness.

• 3. High-temperature firing

After the coating is completed, the cufflinks will enter the high-temperature firing stage, which is also the core part of the enamel process. In this process, the enamel cufflinks will be placed in a specially designed kiln and heated to about 1600 degrees Celsius. At such a high temperature, the silicon powder in the enamel gradually melts and closely combines with the metal base to form a smooth, hard and shiny surface. The firing time and temperature need to be strictly controlled, because too long firing time or too high temperature will cause the enamel to discolor or crack, while too low temperature may not completely melt the enamel, resulting in an uneven surface.

• 4. Cooling and polishing

After firing, the enamel cufflinks need to be cooled slowly to prevent cracks caused by sudden temperature changes. After cooling, the surface of the cufflinks is usually hand-polished to further enhance the gloss and surface smoothness. This process not only removes minor defects that may occur during the firing process, but also makes the color of the cufflinks more full and translucent, enhancing the visual effect.

• 5. Final quality inspection and assembly

After all processing steps are completed, the enamel cufflinks will undergo strict quality inspection to check the color, gloss, surface flatness and structural integrity. Only products that pass the quality inspection will enter the assembly stage to install accessories such as back buckles or chains to ensure wearing comfort and stability. Finally, the finished products will be cleaned and packaged and prepared for shipment.

• 6. Personalization of enamel cufflinks

For customized enamel cufflinks, every step of the process may vary depending on the customer’s special requirements. The designer may need to make special designs based on the patterns or badges provided by the customer, or even use different colors of enamel powder for gradient effects during the coating process. Every detail is carefully polished to ensure that the customized enamel cufflinks fully meet the customer’s expectations and become a unique work of art.
