Leading the innovation of spraying and achieving excellent quality - Automatic spraying machine for plastic parts
Plastic parts spraying is an important surface treatment technology. It can not only improve the appearance and texture of the product, but also has practical functions and protective effects. The following are several aspects of the necessity of plastic parts spraying:
1. **Improve adhesion**: Plastic parts need to be surface treated before painting, such as removing mold release agents, foreign matter, dirt, etc., to improve the adhesion of the paint and reduce defects on the surface of the paint film.
2. **Eliminate internal stress**: Residual stress may be generated during plastic molding, which is not conducive to the wetting of the paint and the adhesion of the coating. Annealing can relieve the internal stress during plastic molding and prevent cracking after painting.
3. **Remove surface contaminants**: After plastic parts are processed and molded, there may be mold release agents or other oil stains on the surface. These contaminants will affect the adhesion and appearance of the coating, so they need to be cleaned.
4. **Beautify the appearance**: Spraying can improve the appearance of plastic parts, provide a variety of colors and texture effects, and meet the design requirements of different products.
5. **Protective effect**: The coating layer can provide additional protection for plastic parts to prevent damage to plastic parts caused by environmental factors such as chemical corrosion and ultraviolet radiation.
6. **Increase product added value**: Through the spraying process, plastic parts can have a more refined and high-end appearance, which helps to improve the market competitiveness of products and consumer recognition.
7. **Adapt to automated production**: With the development of spraying technology, methods such as electrostatic spraying can adapt to the needs of automated and large-scale production and improve production efficiency.
8. **Environmental protection and energy saving**: Modern spraying technology focuses on environmental protection and energy saving. For example, HVLP spraying technology can reduce mist and overspray, and reduce the emission of paint and solvents. It is an environmentally friendly spraying technology.
In summary, spraying of plastic parts is an indispensable part of the production process of plastic products. It not only improves the appearance and texture of the product, but also has practical protection and functionality.
