High-frequency welding machines are widely used in automotive interior components. Below are some specific application scenarios:

1. Car Sun Visors
High-frequency welding machines can be used for welding car sun visors, including edge-less welding, hemming, and other processes. They ensure the integrity and functionality of the visors. The pressurization system stabilizes pressure, delivers smooth welding edges, and maintains mechanically stable structures.

2. Car Door Panels
These machines are suitable for hot welding of car door panels, such as those composed of 30% PVC fabric with sponge, laminated cardboard, or PVC fabric interiors. Customized equipment and molds can be designed based on the size of door panels to meet manufacturers' needs.

3. Car Seat Components

Ventilation Bags: Achieve perimeter welding and sealing for ventilation bags by sandwiching mesh vent net materials between dual-layer TPU films, with simultaneous melt-cutting and edge trimming.
Lumbar Support Airbags: Perform edge welding and sealing for lumbar support airbags.
Backrest Cushions: Ensure strong connections between backrest cushions and seat frames through welding.

4. Car Floor Mats and Carpets

Welding and Embossing: Suitable for PVC spray-molded mats, automotive spray-molded mats, and other heat-pressed embossing applications.
PVC Velvet Carpets: Apply to PVC flocked carpets, door mat embossing, and various seat cushion patterns, enhancing durability and aesthetics.

5. Car Interior Panels
Used for hemming, molding, and welding processes on hard-shell vacuum-packaged interior panels.

6. Steering Wheel Covers
Enable secure welding of steering wheel covers to prevent detachment or damage during use.

7. Car Headliners
Ensure robust bonding between headliner materials, improving stability and durability.

8. Embossing and Branding
High-frequency welding machines can imprint patterns, logos, letters, or 3D textures on automotive interiors. With additional attachments, they also support foil stamping processes.
