  Have you ever wondered how the latest styles of 

automobiles came to be?

 The next time you drive or ride in a car, you’ll notice 

much of the interior consists of plastic. The molding around 

the entertainment center, the steering wheel, and more all 

consist of plastic.

Take a look at the exterior. The headlights and bumpers? In 

many models, they consist of, you guessed it, plastic.

But plastic [url=https://www.jetchinamold.com/]automotive 

molding[/url] is relatively new.

Automobiles before the 1970s used metal for everything. This 

made them heavy and clunky.

It wasn’t until the 1940s and 1950s when the plastics 

started booming. By the 1970s, vehicles started using 

lightweight plastic for decorative elements. It wasn’t 

until the 1980s that some exterior elements started to use 

plastics.

The 2000s welcomed the use of plastics for structural parts 

making vehicles lighter and more fuel-efficient.

Today, automotive molding is an efficient way to manufacture 

plastic components for vehicles. Here are the types and 

advantages of [url=http://www.jetchinamold.com/auto-mold/]

How Automotive Molding Works

Injection molding is one of the most popular processes of 

automotive [url=http://www.jetchinamold.com/electronic-

car parts and cell phones to toys and storage containers.

Injecting molding uses an injection machine to create a foam 

or [url=http://www.jetchinamold.com/plastic-mould/]plastic 

mold[/url]ing. To use it, you feed plastic powder or 

granular into the machine which heats it into molten 

plastic.

Once melted, the plastic enters an injector which pushes it 

into a shaped cavity. It fills the cavity and sits until it 

cools and hardens. After it hardens, you can remove it from 

the metal cavity and use it for its intended purpose.

A similar process works with most polymers, resins, foams, 

and silicone rubber. The process and machine used will 

change a little depending on the size of the part you’re 

molding and material used.
