The advantages of engineering plastics in the automotive industry
Engineering plastics are playing an increasingly important role in automotive manufacturing. Currently, there are about 30,000 parts in one car, of which one-third are made of plastic. There are about 40 different types of basic plastics used to manufacture automotive components.
What are the advantages of engineering plastics in the automotive industry?
1. Weight reduction. Using engineering plastic parts can reduce the weight of the car, which consumes less energy during driving. Reducing the weight of the body means improving the power-to-weight ratio, which can provide a better acceleration experience with the same engine power.
2. Safety. A bumper made of composite engineering material is 50% lighter than a metal bumper and has better elasticity, which can absorb more energy during collision.
3. Complexity of parts. Engineering plastic parts are processed through injection molding, which makes it easier to make complex parts than metal materials.
4. Cost control. The processing cycle of plastic parts is shorter, and there is no need for secondary machining operations. The corresponding appearance treatment can be obtained directly through the injection mold, which can effectively reduce processing costs.
