What You Didn’t Know About Automotive Plastic Parts


When it comes to automotive manufacturing, automotive plastic parts play a vital role in the construction of vehicles. The global injection molded plastics market was valued at USD 343.23 billion in 2020 and is expected to grow at a compound annual growth rate (CAGR) of 5.6% from 2021 to 2028, according to Zion Market Research. Here are five things you may not have known about automotive plastics parts.

1. Creates Lighter Vehicles

Vehicles become lighter in weight, which improves fuel efficiency, with the use of plastics. For example, replacing a steel bumper with a plastic one can save up to 50 pounds in weight. Reducing the weight of vehicles by 10% can improve fuel economy by 6-8%.

2. Enhances Safety

Plastics can help improve the safety of vehicles by absorbing impact energy in the event of a collision. Plastics are often used in automotive safety features such as airbags and seatbelts.

3. Improves Acoustics

Using automotive plastics parts can also improve the acoustics of vehicles by reducing noise, vibration, and harshness (NVH). For example, replacing a steel panel with a plastic one can reduce NVH by up to 50%.

4. Reduces Emissions

These parts help reduce emissions by offering lighter weight and improved fuel efficiency. In addition, some plastics are made from recycled materials, which further reduces emissions. Gas emissions from vehicles are a major contributor to air pollution and climate change.

5. Aesthetically Appealing

Since you can mold plastics into just about any shape, automotive designers have more freedom to create aesthetically pleasing vehicles. In addition, they can paint plastics or apply other finishes to them to create the desired look.

6. Offers Design Flexibility

Utilize design flexibility that can be used to create unique designs. For example, manufacturers can mold plastics into different shapes and colors, which allows for more creativity in automotive design. An example of this is the use of carbon fiber-reinforced plastics (CFRP) in automotive manufacturing. CFRP is a strong and lightweight material that can create intricate designs.

Car designers and manufacturers rely on automotive plastics parts to create safe, efficient, and stylish vehicles. The use of plastics in automotive manufacturing is expected to continue to grow in the coming years. As more vehicles are produced with plastic parts, it’s important to be aware of the benefits they offer. If you’re searching for custom plastic parts, turn to Hansen Plastics.
