Plastic Components for Automobiles

From the dashboard you see every time you get into your car, to the hidden parts under the hood, plastic components are everywhere — and for good reason. They’re lightweight, durable, and can be made into complex shapes that metal often can’t match.

Behind these plastic parts is a key manufacturing process called injection molding. It allows for fast and accurate production of high-quality plastic components — from small connectors to large body parts.

At Senses, we specialize in injection molding services for the automotive industry. With professional experience and advanced technology, we offer full-service support — from design to mass production — helping our customers create reliable and cost-effective plastic parts.

Common Plastic Components Used in Vehicles

Plastic components are integral to vehicle design due to their versatility, durability, and cost-effectiveness. Here are some of the most common plastic parts used in various sections of a vehicle:

Interior Parts

• Dashboards: The dashboard is one of the largest interior components, often made from materials like ABS (Acrylonitrile Butadiene Styrene) or PP (Polypropylene). It not only serves as a cover for the instrument panel but also integrates air vents, storage compartments, and other functional elements.
• Door Panels: Door panels provide both aesthetic appeal and functionality. They include window controls, armrests, and sometimes even speaker covers. These are typically made from durable plastics that can withstand frequent use.
• Air Vents: Small but essential, air vents direct airflow within the cabin. They need to be lightweight and resistant to wear and tear, which makes plastic an ideal material.
• Trim Pieces: Various trim pieces around the car interior, such as those around the gear shift or door handles, enhance the vehicle’s aesthetics while being easy to clean and maintain.

Exterior Parts

• Bumpers: Modern bumpers are commonly made from polypropylene (PP) because they are lightweight yet strong enough to absorb impacts. They protect critical components of the vehicle during minor collisions.
• Grilles: Positioned at the front of the vehicle, grilles allow air to flow into the engine compartment while adding to the car’s overall look. Made from durable plastics, they resist corrosion and weathering.
• Mirror Housings: Side mirrors need to be sturdy but lightweight. Plastic mirror housings meet these requirements while also offering flexibility in design.
• Lighting Covers: Headlights and taillights have covers made from polycarbonate (PC) or acrylic, which provide excellent transparency and impact resistance.

Under-the-Hood Components

• Engine Covers: Engine covers shield the engine from debris and improve the appearance under the hood. Materials like PA (Polyamide) or PBT (Polybutylene Terephthalate) are chosen for their heat resistance.
• Intake Manifolds: Intake manifolds guide air into the engine cylinders. Made from reinforced plastics, they offer a balance between strength and weight reduction.
• Sensor Housings: Sensors play a crucial role in monitoring engine performance. Their housings must protect sensitive electronics from heat and vibration, making high-performance plastics ideal.

Functional & Safety Components

• Airbag Housings: Airbags save lives by deploying quickly in case of accidents. Their housings need to be robust and reliable, ensuring the airbags deploy correctly when needed.
• Seatbelt Components: Seatbelts keep passengers safe. The buckles and retractors are often made from tough plastics that can withstand significant force.
• Electrical Connectors: Modern vehicles contain numerous electrical systems. Electrical connectors made from durable plastics ensure secure connections, resisting temperature changes and vibrations.
