1. Preparation work
Material preparation:
Plastic products: Prepare plastic products that require oil spraying treatment to ensure that the surface of the product is clean and free of stains.
Coatings: Choose suitable coatings according to customer requirements, such as regular paint, UV paint, rubber paint, etc.
Equipment preparation:
Spray equipment: Check and debug automatic spray equipment to ensure proper operation.
Spray painting workshop: Ensure that the spray painting workshop is clean, dust-free, and the temperature and humidity are controlled within an appropriate range.
2. Pre processing
Cleaning:
Use ultrasonic cleaning or solvent cleaning methods to remove oil, dust, and impurities from plastic surfaces.
Electrostatic dust removal:
Further remove small particles on the plastic surface through electrostatic precipitators to ensure the spraying effect.
3. Spray coating process
Primer spraying:
Spray primer: Apply a uniform layer of primer on the plastic surface to enhance the adhesion and durability of the coating.
Baking: Place the plastic product coated with primer in an oven to cure the primer. For Brother Hui spraying, it is recommended to control the temperature at 60-80 degrees Celsius for 30-60 minutes.
Intermediate processing:
Polishing: Use fine sandpaper to lightly polish the surface of the primer, removing particles and unevenness from the surface.
Topcoat spraying:
Spray paint: Spray paint according to customer requirements, which can be monochrome, multi-color, or gradient color. Use automatic spraying equipment to ensure even coating.
Baking: Place the plastic product in the oven again to bake and cure the topcoat. The temperature is usually controlled at 60-80 degrees Celsius for 30-60 minutes.
4. Post processing
Surface treatment:
According to the needs, additional treatments such as surface polishing, screen printing, and transfer printing are carried out to improve the appearance quality of the product.
Quality inspection:
Appearance inspection: Check whether the sprayed plastic products have a uniform appearance, no color difference, and no bubbles.
Adhesion testing: Use tape testing and other methods to test the adhesion of the coating, ensuring that the coating is firm.
Wear resistance test: Conduct wear resistance tests to ensure the durability and wear resistance of the coating.
5. Packaging and Shipping
Packaging:
Packaging plastic products that have been sprayed and passed quality inspection, using dust-proof and shockproof packaging materials to ensure that they are not damaged during transportation.
Shipment:
Arrange shipment based on customer orders
Summary
The plastic spray processing technology process is scientifically rigorous, covering various links from pre-treatment, spraying to post-treatment. By strictly controlling each process step, we ensure that the sprayed products have a good appearance, excellent adhesion, and durability
