Main Application Scenarios
1. Air conditioning system
Inlet/outlet duct: connects the air conditioning box and the air outlet to deliver hot and cold air to the car.
Defrost duct: directs hot air to the windshield for quick defog and defrosting.
Seat ventilation duct: some high-end models use it for air flow delivery in the seat ventilation system.
2. Engine cooling system
Radiator duct: guides cooling air flow to the radiator or intercooler to improve heat dissipation efficiency.
Turbocharger intercooler duct: some models use it for air delivery to the intercooler.
3. Battery pack/motor cooling system (new energy vehicles)
Provides forced cooling air flow for the battery pack or motor to maintain a suitable operating temperature.
4. Other ventilation systems
Auxiliary functions such as air circulation in the car and trunk ventilation.
Advantages Of Air Duct Blow Molding Machine Technology
1. Lightweight
Using lightweight plastics such as PE and PP, which are lighter than metal or rubber tubes, meet the needs of automobile weight reduction.
2. Integrated molding
The blow molding process can produce complex shapes (such as curved and special-shaped structures), reduce splicing nodes, and reduce the risk of air leakage.
Weather resistance and durability
Anti-oil, high and low temperature resistance (-40℃~120℃), anti-aging, adapt to the harsh environment of the engine compartment.
Cost-effectiveness
The mold cost is low, suitable for mass production, and the material can be recycled.
Typical Material Selection
- Polyethylene (PE): Good flexibility, often used for bending air ducts.
- Polypropylene (PP): Better high temperature resistance, suitable for use near the engine compartment.
- TPE/TPV: Used when higher elasticity is required, such as hoses at connection locations.
Industry Development Trends
1. Adaptation to new energy vehicles
Higher requirements for high temperature resistance and flame retardancy of air ducts (such as battery cooling systems).
2. Intelligent design
Integrated sensors or active air flow control valves to optimize air volume distribution.
3. Environmentally friendly materials
Application of bio-based plastics or degradable materials.
Selection Considerations
- Sealing: Need to pass wind pressure test to prevent air leakage.
- NVH performance: Smooth inner wall or add silencer structure to reduce airflow noise.
- Installation convenience: Connection methods such as snap-on and flange must match the vehicle design.
Blow-molded automobile air ducts have become key components of modern automobile ventilation systems due to their lightweight, high integration and cost advantages. With the process upgrade and material innovation of air duct blow molding machine, their application scope will be further expanded.
