What are the different types of plastic molding processes used in automotive manufacturing?

There are several plastic molding processes used in automotive manufacturing. Here are some of the most common types:
Injection molding: This is the most widely used plastic molding process in the automotive industry. Molten plastic is injected into a mold cavity under high pressure and cooled to form a part.
Blow molding: This process is used to create hollow plastic parts, such as fuel tanks and ductwork. The plastic is melted and formed into a tube, which is then inflated to conform to the shape of the mold.
Thermoforming: This process is used to create large, shallow parts such as instrument panels and interior trim pieces. The plastic sheet is heated until it is soft and then formed over a mold using vacuum pressure.
Rotational molding: This process is used to create large, hollow parts such as water tanks and air ducts. The plastic is placed into a mold and then rotated on multiple axes while heated, causing the plastic to evenly coat the mold surface.
Compression molding: This process is used to create high-strength, high-durability parts such as brake components and engine covers. The plastic is placed into a heated mold and compressed under high pressure until it takes on the desired shape.
Each plastic molding process has its advantages and disadvantages, and the choice of process will depend on the specific application and required properties of the final product.
