The automotive interior parts flocking production line usually consists of a series of professional equipment that work in coordination to firmly attach the flocking to the surface of the interior parts, achieving the goal of enhancing the aesthetics and tactile sensation of the interior. The following is a detailed introduction to its main component equipment:

Pre-treatment Equipment

• Cleaning Machine: It is used to remove impurities such as oil stains, dust, and release agents from the surface of automotive interior parts. Common types include spray cleaning machines and ultrasonic cleaning machines. The spray cleaning machine sprays cleaning liquid onto the surface of the workpiece through high-pressure nozzles and removes stains by means of mechanical scouring force. The ultrasonic cleaning machine, on the other hand, relies on the cavitation effect generated by ultrasonic waves in the cleaning liquid to more finely remove tiny particulate contaminants, ensuring that the surface of the workpiece is clean and providing a good foundation for the subsequent flocking process.

• Drying Equipment: After cleaning, the interior parts need to be dried to prevent the residual moisture from affecting the flocking quality. The hot air circulation oven is commonly used. It generates hot air through the internal heating elements, and the hot air circulates inside the oven by means of a fan to dry the workpiece evenly. It can effectively control the drying temperature and time, ensuring that the workpiece is thoroughly dried without being damaged by overheating.

Flocking Equipment

• Flocking Machine: The core equipment of the flocking production line. According to the working principle, it can be divided into electrostatic flocking machines and mechanical flocking machines. Electrostatic flocking machines are mostly used in the production of automotive interior parts. When it works, the flocking fibers are charged under the action of a high-voltage electrostatic field, fly vertically towards the surface of the interior parts that have been pre-coated with an adhesive, and are evenly implanted into the adhesive to form a dense and neat flocking layer. The performance of the flocking machine directly affects the quality and efficiency of flocking, including key indicators such as the implantation depth and uniformity of the flocking fibers.

• Flocking Supply System: It is responsible for continuously and stably supplying flocking fibers to the flocking machine. It generally consists of a flocking storage tank, a flocking conveying pipeline, and a quantitative feeding device. The storage tank is used to store flocking fibers of different colors, materials, and specifications. The flocking conveying pipeline transports the flocking fibers to the working area of the flocking machine under the action of a fan. The quantitative feeding device can precisely control the amount of flocking fibers transported each time, ensuring the stability of the flocking supply during the flocking process and avoiding flocking quality problems caused by uneven flocking supply.

• Gluing Equipment: Before flocking, an adhesive needs to be evenly applied to the surface of the automotive interior parts so that the flocking fibers can be firmly attached. Common gluing equipment includes roll coaters and sprayers. The roll coater evenly spreads the adhesive on the surface of the workpiece through a rotating glue roller, which is suitable for the interior parts with a large area and regular shape. The sprayer atomizes the adhesive and sprays it onto the workpiece by means of a spray gun, which can achieve more accurate gluing for the interior parts with complex shapes, ensuring that the adhesive coating is uniform in thickness and there is no omission, thus improving the adhesion and overall quality of the flocking.

Post-treatment Equipment

• Curing Equipment: After flocking, the interior parts need to be cured to quickly cure the adhesive and enhance the bonding force between the flocking fibers and the surface of the workpiece. Commonly used curing equipment includes ultraviolet (UV) curing ovens and hot air curing ovens. The UV curing oven uses ultraviolet light to irradiate the flocked workpiece, so that the adhesive containing a photosensitizer quickly undergoes a photochemical reaction and cures, which has the advantages of fast curing speed, high efficiency, and low energy consumption. The hot air curing oven cures the adhesive by heating it with high-temperature hot air, which is suitable for the interior parts materials that are not sensitive to temperature, ensuring that the adhesive is fully cured and improving the durability of the flocked products.

• Cleaning Equipment: It is used to remove the excess floating flocking fibers on the surface of the interior parts after flocking, making the product surface cleaner. Vibration cleaners and dust suction devices are common cleaning equipment. The vibration cleaner generates high-frequency vibrations to make the loosely attached floating flocking fibers fall off, and then cooperates with the dust suction device to suck away the fallen flocking fibers, ensuring that the surface quality of the product meets the high standards required for automotive interiors and avoiding the floating flocking fibers from falling off during the use of the vehicle and affecting the in-vehicle environment and user experience.

Conveying Equipment

• Production Line Conveying System: It connects the equipment of each process to realize the automated transmission of automotive interior parts in the production line. Common conveying methods include chain conveying, belt conveying, and hanging conveying. Chain conveying has a strong structure and is suitable for the conveying of heavier and larger-sized interior parts. Belt conveying has the characteristics of stable operation and low noise and can well adapt to interior parts of various shapes. Hanging conveying can make full use of space and is more suitable for some interior parts with irregular shapes that require special postures for processing. The speed of the conveying system can be adjusted according to the requirements of the production process to ensure that the production rhythm between each process is coordinated and consistent, improving the production efficiency of the entire production line.
