The manufacturing process of spray painting for packaging wooden boxes mainly includes the following steps:

Production foundation: First, make a flat wooden box as the foundation. Polish and buff the surface of the box to ensure a smooth and even finish. Primer application: Apply a layer of primer. Primer can fill and strengthen the wood texture, while also improving the adhesion of the paint surface. Apply intermediate paint: After applying the primer, apply another layer of intermediate paint. The color of the intermediate paint can be adjusted according to design requirements. Topcoat: After the intermediate coat is completely dry, apply another layer of topcoat. Topcoat is the focus of the wood box paint process, which can play a protective and beautifying role. Grinding and polishing: After the topcoat is dry, perform grinding and polishing treatment. This step can make the surface of the wooden box smoother, more uniform, and enhance its luster. Processing carving: If carving is required on the surface of the wooden box, it can be done before grinding and polishing. Wax application: Finally, apply a layer of wax on the surface of the wooden box to protect the paint surface from contamination and scratches. The above are the basic steps for manufacturing packaging wooden boxes using spray painting technology. Each step requires precise operation to ensure the final product quality. At the same time, the paint used also needs to be selected according to specific situations, such as nitro paint and alkyd paint, to ensure that the appearance and performance of the wooden box reach the best state.
