Description

Technical Field

[0001] The utility model relates to the technical field of paint spraying brackets, in particular to a paint spraying bracket for plastic parts. Background Art

[0002] Plastic parts spray painting technology is a surface treatment process, which is mainly used on plastic products. The main purpose of this technology is to protect the surface of plastic products from corrosion, scratches and other damages, and at the same time improve the appearance of the product, making it more beautiful and durable. Common process flows include: paint stripping, grinding, cleaning, spraying primer, spraying topcoat and other steps. During the spraying process, the paint is evenly sprayed on the plastic surface through a spray gun to form a uniform coating. Plastic spraying can protect the plastic surface from the influence of the external environment, such as moisture, oxygen, chemicals, etc. In addition, plastic spraying can also cover the defects on the surface of the product and improve the overall quality and market competitiveness of the product. When choosing a coating, PU paint is a common choice. It is a general term for all polyurethane coatings. Its film-forming method is natural film formation without special processes. In general, plastic parts spray painting technology is an effective plastic surface treatment method that has been widely used in many fields.

[0003] Existing plastic parts brackets generally have a relatively simple way of fixing plastic parts, which makes it difficult to ensure that the plastic parts can be stably clamped and fixed during painting, thereby affecting the spraying quality; therefore, we propose a plastic parts spraying bracket to solve this problem.
