The pressing process utilizes a preset pressing path to press the outer skin and the car armrest frame together, ensuring the outer skin fully conforms to the frame and improving the appearance of the car armrest. The pressing path is preset based on different frame and outer skin models, with different paths pre-set in the pressing fixture program. The program controls the pressing path.

[0060] S7: Baking. The car armrest frame and skin, which have been pressed together in step S6, are baked in an oven to dry the glue and ensure the adhesion between the skin and the car armrest frame. The baking temperature is 180-200℃ and the baking time is 15-20 minutes. Before baking, the pressed skin and car armrest frame need to be left to stand at room temperature for 15-20 minutes to ensure that the pressed skin is completely attached to the armrest frame.

After spraying the curing agent, cover the surface of the finished product with a protective film. The protective film adheres to the surface of the finished product through the curing agent. Spray curing agent onto the skin surface. After spraying the curing agent, cover the surface of the finished product with a protective film. The protective film adheres to the surface of the finished product through the curing agent. The curing agent needs to be mixed with water-based adhesive in a ratio of (1-3):100. The curing agent has the best adhesion, which makes the protective film and the skin adhere better.

[0062] S9: Install the accessories. Install the small table into the small table storage space, install the double-leaf armrest door onto the top of the storage space, and install the cup holder into the cup storage space. The top of the double-leaf armrest door is covered with sponge and leather to accommodate elbow rest needs. The small table is prefabricated and fixed to the armrest frame with bolts. The connection between the small table and the armrest frame relies on a multi-section hinged rod, which can be used to retract and unfold the small table. It is used when unfolded and not for storage when not in use. The double-leaf armrest door is prefabricated and serves not only as an elbow rest but also as a door to the storage space. The cup holder is prefabricated and used to hold teacups to prevent them from tipping over during vehicle movement. The top of the armrest door is covered with 5-10mm thick sponge and leather for cushioning and comfort.

[0063] S10: Trimming. Partial trimming of the car handrail obtained in step S9 is performed to avoid problems that affect the appearance and improper assembly. After the trimming is completed, the finished car handrail is obtained. The exposed parts of the skin are manually trimmed and repaired to avoid the skin edges being exposed and affecting the appearance. Each component is tested for opening and closing to prevent the components from failing to work.
