The production process of painted wooden doors usually involves the following steps:
- 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.
- 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.
- Sanding:
- Sanding: After the primer dries, sand the door’s surface to make it smoother, preparing it for the next coat.
- 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.
- 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.
- 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.
- 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.
- Packaging and Delivery:
- After passing inspection, package the door to protect the finish. It can then be delivered to customers or distributors.
