The production process of Sinor baking paint for wooden doors

The production process of painted wooden doors usually involves the following steps:

1. Preparation:
   • Door Preparation: Choose suitable wood and cut, process, and assemble the required door panels.
   • Surface Preparation: Ensure the door’s surface is smooth, free from impurities, dust, and grease to ensure good adhesion of coatings.
2. Primer Application:
   • Primer Coating: Apply a primer coat to the door’s surface. Priming enhances adhesion, levels the surface, and prevents wood from absorbing water and corroding.
3. Sanding:
   • Sanding: After the primer dries, sand the door’s surface to make it smoother, preparing it for the next coat.
4. Coating:
   • Painting: Use spray or brush techniques to apply paint onto the door’s surface. Multiple layers are usually applied, with sanding and cleaning between each coat to achieve a smooth and even finish.
5. Drying and Curing:
   • Drying: After coating, place the door in a controlled-temperature drying room to gradually remove moisture from the paint layers.
   • Curing: Post-drying, the door might enter a curing chamber where high temperatures enhance the durability and quality of the coating.
6. Sanding and Polishing:
   • Sanding: After curing, perform fine sanding to ensure the coating surface is even.
   • Polishing: Finally, polish the door’s surface to enhance its gloss and appearance.
7. Inspection and Quality Control:
   • Inspect the coatings to ensure color, texture, gloss, etc., meet expectations.
   • Implement quality control measures to ensure the door meets required standards.
8. Packaging and Delivery:
   • After passing inspection, package the door to protect the finish. It can then be delivered to customers or distributors.
