1. Automotive Exterior Components
Lighting Systems: Welding of headlight/taillight lenses to their housings; requires IP67–IP68 sealing standards to prevent fogging and moisture ingress; typically utilizes 20kHz/35kHz equipment, completing the process in 2–3 seconds with no material overflow or visible marks.
Bumpers & Grilles: Segmented welding of PP/ABS bumpers and assembly of grille components; serves as an alternative to screws and clips, offering a seamless appearance and resistance to vibration and impact.
Functional Exterior Parts: Side mirror housings, wiper bases, and fuel tank cap assemblies; features high weld strength and excellent sealing properties, capable of withstanding extreme outdoor temperatures (-40°C to 125°C).

2. Automotive Interior Components
Dashboards & Center Consoles: Instrument bezels, display brackets, air vents, and storage compartments; utilizes high-power 15kHz/20kHz equipment with contoured welding horns to prevent thermal deformation; replaces clips to enhance the overall aesthetic and tactile quality of the interior.
Door Panels & Pillars: Door trim strips, armrests, interior door panels, and A/B-pillar trim pieces; produces invisible welds with zero VOC emissions, thereby improving interior air quality.
Seats & Headliners: Plastic seat back panels, headliner mounting brackets, and seatbelt guides; minimizes deformation when welding thin-walled components, achieving a welding precision of ±0.01mm.

3. Engine Bay & Chassis Components
Intake & Cooling Systems: Intake manifolds, coolant reservoirs, hose connectors, and filter housings; compatible with glass-fiber reinforced materials such as PA66+GF30, ensuring reliable sealing in high-temperature environments.
Sensors & Electrical Enclosures: ABS sensor housings, tire pressure monitoring modules, wiring harness connectors, and fuse boxes; provides IP67-standard sealing with a minimal heat-affected zone, effectively protecting internal circuitry.

Chassis Shields & Protective Covers: Engine underguards, chassis aerodynamic panels, and battery pack protective covers; achieves a weld strength reaching 80%–95% of the base material's strength, offering resistance to gravel impact and corrosion. 

4. Dedicated Applications for New Energy Vehicles

Battery Pack Components: Battery top covers, insulation covers, module end plates, and charging port protective covers; featuring watertight sealing, electrical insulation for safety, spark-free operation, and minimal thermal impact, while being fully compatible with automated production lines.

Lightweight Structural Components: Battery tray reinforcement ribs, lightweight interior brackets, and plastic-metal hybrid connectors; contributing to a 5%–10% reduction in overall vehicle weight and lowering energy consumption.
