Products Description
The flocking production line of China Hengjiu Jinyi Intelligent Technology Co., Ltd. has been constantly updated and making breakthroughs in the automotive industry. This project is a flocking line for automotive tailgate springs. In order to provide users with a more premium riding experience, it reduces the noise inside the vehicle caused by friction. We are highly confident in the field of flocked springs.
The technological process of spring flocking thread generally includes the following steps:
Spring Surface Treatment
First, the spring needs to be cleaned and degreased to remove oil, dust, and impurities on the surface, ensuring that the flocking glue can adhere well. Special cleaning agents and degreasers can be used, and the treatment can be carried out through methods such as soaking, spraying, or wiping. Then, rinse it thoroughly with clean water and dry it.
Glue Application
Apply the special flocking glue evenly on the spring surface. There are various ways to apply the glue, and common methods include dip - coating, spray - coating, and brush - coating. In dip - coating, the spring is completely immersed in the glue solution so that the spring surface can fully absorb the glue. Spray - coating uses a spray gun to evenly spray the glue on the spring surface, which allows for better control of the glue amount and coating uniformity. Brush - coating is suitable for small springs or partial flocking, where a brush is used to apply the glue to the required flocking areas. After applying the glue, the spring needs to be left standing for a period of time to allow the glue to reach a certain viscosity, usually 5 - 15 minutes, depending on the type of glue and the ambient temperature.
Flocking
Use the electrostatic flocking method to evenly adsorb the fluff onto the spring surface coated with glue. The electrostatic flocking equipment mainly consists of a flocking box, a high - voltage electrostatic generator, and a fluff feeding device. During the flocking process, first place the spring in the flocking box, then start the high - voltage electrostatic generator to create a strong electrostatic field inside the flocking box. At the same time, the fluff feeding device evenly delivers the fluff into the flocking box. Under the action of the electrostatic field, the fluff quickly flies towards the spring surface and vertically embeds into the glue layer. The flocking time is generally 3 - 10 minutes, depending on the size, shape of the spring, and the required flocking density.
Drying
The flocked spring needs to be dried to remove the moisture in the glue and fluff and to solidify the glue, thereby improving the firmness of the flocking. The drying temperature and time are determined according to the characteristics of the glue and the material of the spring. Generally, the temperature ranges from 60 - 120°C, and the drying time is 10 - 30 minutes. Drying equipment such as ovens or drying tunnels can be used. Pay attention to ventilation during the drying process to remove the volatilized solvents and moisture.
Inspection and Refinement
The dried spring needs to be inspected to check the quality of the flocking, including the density, uniformity, and firmness of the fluff. If problems such as uneven flocking, fluff shedding, or impurities are found, they need to be refined in time. For areas with poor local flocking, additional fluff can be added. For excess fluff or impurities, a brush or a vacuum cleaner can be used for cleaning.
Packaging
The spring flocking products after inspection and refinement need to be packaged to prevent damage during transportation and storage. The packaging method can be selected according to the customer's requirements and the characteristics of the product. Generally, plastic bags, cartons, or plastic films are used for packaging. For some high - precision or spring flocking products with special requirements, vacuum packaging or nitrogen - filled packaging can also be used.
The application fields of spring flocking production lines are very extensive. Here are some of the main application areas:
Automotive Industry
It is used for flocking components such as automobile seat adjustment springs, suspension springs, and engine valve springs. Flocking can reduce friction and noise during the spring's operation, enhancing ride comfort. Meanwhile, it can also prevent corrosion and dust, thus extending the service life of the springs.
Furniture Industry
Springs in furniture like sofas, mattresses, and office chairs often require flocking treatment. Flocked springs can provide softer elastic support, increasing the comfort of the furniture. Additionally, they prevent the springs from rusting and enhance the quality and aesthetics of the furniture.
Electronics and Electrical Appliance Industry
Flocking technology is applied to the shock - absorbing components, switch springs, and internal springs of some electronic devices and electrical appliances. This helps reduce the impact of spring vibrations on electronic components, improving the stability and reliability of the equipment. Moreover, it prevents static electricity generation, protecting electronic devices from electrostatic interference.
Toy Industry
After flocking treatment, springs in toys such as those in toy guns and bouncing toys can make the toy's movements softer and smoother, reduce noise, and improve the safety and durability of the toys, providing a better user experience for children.
Medical Device Industry
In some medical devices, such as blood pressure monitors and massagers, flocking of springs can play roles in shock absorption, noise reduction, and anti - slip. It improves the performance and comfort of medical devices while meeting the strict hygiene and safety requirements of the medical device industry.
Industrial Machinery Field
For springs in various industrial machinery, such as those in textile machinery, printing machinery, and packaging machinery, flocking can improve the working performance of the springs, reduce wear and noise, enhance the operating efficiency and stability of the machinery, and lower maintenance costs.
