**Painting Process**
The painting process involves applying several layers of paint onto a substrate that has been ground to a specific level of roughness, typically a high-density sheet. Afterward, the coated object is baked at a high temperature. This method currently requires high-quality paint and excellent color rendering. The advantages include vibrant colors, strong visual impact, a smooth surface finish, easy cleaning, and good resistance to moisture and fire, making it a premium surface treatment option.
However, this process has some disadvantages. It is quite complex and costly, which significantly increases the final price of the product. Additionally, its wear resistance is not as strong as other methods, potentially affecting the design and durability of smart locks over time.
**Spraying Process**
Electrostatic spraying is a technique that uses a high-voltage electrostatic field to direct negatively charged paint particles toward the workpiece, allowing them to adhere to its surface. The equipment includes a spray gun, a spray cup, and a high-voltage power supply for electrostatic charging.
This method offers better wear resistance and a more cost-effective solution. However, the surface may have a slightly textured appearance, which can affect the visual appeal. Furthermore, the surface finish may not be as resistant to environmental factors as other techniques.
**Plating Process**
Electroplating is one of the most commonly used surface treatments. It involves depositing a metal layer onto a base material through an electrolytic process. This method is simple to operate, cost-effective, and often results in a hard, attractive finish, such as chrome plating. However, it does not perform as well as other processes in terms of corrosion resistance.
**New Technologies in Hardware Industry**
New processes are now being introduced into the hardware industry. One of the latest innovations is the "wind grinding" process, which has been applied in products like Bida smart locks. This unique technology uses organic materials mixed with non-floating aluminum paste to create a bright, hammer-like paint finish. The surface features a texture resembling the patterns left by hammered metal, known as the wind-grinding pattern. This process has been tested in harsh environments and is considered one of the most durable and stable surface technologies available.
Different materials and processes are suited for different product positions, helping to meet the needs of a wider range of consumers. The integration of new technologies continues to drive progress within the industry.
Similar to the traditional method, but replace the stringers and joists with aluminum forming systems, or replace the steel beams with support frames and replace them with metal pillars. This also makes the method more systematic and reusable. Aluminum beams are made as telescopic units so that they can span different distances of support. The telescopic aluminum beam can be used and reused in the structure of various sizes.
