Automotive injection molded parts are widely used in automobile manufacturing, primarily in the following areas:
Engine Parts
Nylon (PA) materials are commonly used in the production of engines and peripheral components. Glass fiber modified nylon can significantly improve strength, product precision, and dimensional stability.
Typical applications include engine hoods, intake manifolds, oil pans, etc., utilizing the lightweight properties of plastics to reduce the overall vehicle weight.
Air Conditioning Parts
Core components such as air conditioning compressors and evaporators are injection molded using thermoplastic plastics such as polypropylene (PP), nylon (PA), and acrylonitrile butadiene styrene (ABS).
The optimized flow channel design of these plastic parts achieves efficient heat exchange while reducing system noise.
Air Filter Components
Air filter housings are manufactured using elastomer materials such as silicone and rubber through elastomer injection molding technology.
Specially formulated materials can withstand the high-temperature environment of the engine compartment while maintaining sealing performance.
Dashboard Components
These are injection molded using thermosetting materials such as glass fiber reinforced materials, polyester, and epoxy resin.
Structural components such as the dashboard frame have their impact resistance improved by adding reinforcing fibers to meet safety regulations.
Seating Accessories
Seat adjustment mechanisms, armrests, and other components are made of thermoplastics such as polypropylene (PP), nylon (PA), and ABS.
Two-color injection molding allows for seamless integration of soft-touch surfaces with rigid structures.
Flooring Accessories
Floor mats, sound insulation pads, and other components are injection molded using elastomers such as silicone and rubber.
A special foaming process enhances sound insulation while maintaining material elasticity.
Roof Panel Components
The roof trim panel uses thermosetting materials such as glass fiber reinforced polyester.
The lightweight design lowers the vehicle's center of gravity while meeting roof crush strength requirements.
Gear Shift Components
The gear shift lever, base, and other components are made of thermoplastic plastics such as PP, PA, and ABS.
Surface treatments can achieve metallic or wood grain finishes.
Steering Wheel Components
The steering wheel frame is injection molded using elastomer materials such as silicone and rubber.
Some high-end models utilize a foaming process to achieve shock absorption and improve driving comfort.
Door Interior Trim Components and Rearview Mirrors
Door interior panels, rearview mirror housings, etc., are made of glass fiber reinforced materials, polyester, and epoxy resin.
Injection molding allows for complex curved surface shapes and integrates wiring harness fixing structures.
