When it comes to parts for automobiles, there are many who think of "metal". However, in recent years parts made of "plastic" are often used. So I will explain why plastic is used in cars.
Why Use Plastics in Cars?
In conclusion, the reason for using plastic parts in cars is "weight reduction". In general, if the same parts are made of metal and plastic, plastic parts are lighter in weight.
One of the main reasons for reducing the weight of automobiles is "improvement in fuel efficiency and driving performance". The famous story mentions "Oil shock", but in modern times the improvement of the fuel efficiency of the car has become a matter of life and death, and the weight reduction of the car is a major issue as a major factor to improve the fuel efficiency. is.
However, with changes in automobile regulations, the types of parts needed for automobiles are on the rise. As long as it is not possible to reduce parts, it is a challenge to reduce the weight of the vehicle by reducing the weight of each part.
What are the benefits of plastics other than lightweight?
There are many advantages to using plastic parts in automobiles besides weight reduction.
The first is that it does not rust. Parts made of metal will rust over time, which can cause fatal problems if not maintained. On the other hand, plastic does not rust, so there is no need for rustproofing.
The second is "high resiliency." Plastic parts are highly resilient compared to metal parts, for example, by making the body skin plastic, it can be easily restored to its original shape if it is slightly bumped. This will reduce the cost needed to repair in the event of an accident.
The third is "high soundproofing and anti-vibration." The car is loaded with an engine, so vibrations and sounds are reasonable. Since plastic is more soundproof and anti-vibration compared to metal parts, it can reduce the noise and vibration in the car.
The fourth is the ability to pursue design. Plastic is easier to process than metal, and it is likely to be easy to process plastic if it is difficult to mold metal parts. This has made it possible to manufacture cars of smooth forms derived from plastics, which were mainly angular designs.
Performance Required for Automotive Plastic Parts
There is a kind of plastic at one bite, and each one has different characteristics. Automobiles have different performance requirements depending on parts. For example, bumpers need high impact resistance, and headlights need high transparency and strength. When using plastic parts in a car, it is important to use plastics that have the performance appropriate to the parts.
