Injection Molding Materials for Automotive Parts

Echofast offers various plastic materials to meet the broad needs of automotive applications. It is important to choose the right plastic. The following is a list of the commonly utilized materials for automotive injection molding products.

Acrylonitrile butadiene styrene (ABS)

As a durable and fairly weather-resistant plastic, ABS is widely used for automotive applications like dashboards and covers.

Polyamide (PA)/ Nylon

With good abrasion and chemical resistance, polyamide (PA) or Nylon being wear-resistant in nature may be used to make items like bushes and bearings.

Polymethyl methacrylate (PMMA) / Acrylic)

Acrylic can be used as a splendid substitute for glass in that it is transparent plastic with high strength, optical clarity, and stiffness. It can be molded into automotive components like headlight covers and internal screens.

Polypropylene (PP)

Polypropylene (PP) is ideal for some of the more high-intensity automotive parts because of its resistance to water, chemicals, and UV. It is used in making parts such as bumpers, cable insulation, and battery cover.

Polyurethane (PU)

PU is frequently used to produce spongy and flexible items like foam seating, which includes car seating. It is also used for making other auto applications, including seals and gaskets, insulation panels, and suspension bushings.

Polyvinyl chloride (PVC)

PVC is a popular synthetic plastic polymer, which makes about 16% of the car’s plastic components. It is flexible and heat resistant, and it is used to make parts that require good chemical resistance,such as interior panels, dashboards, and cable insulation.

Polyethylene(PE)

Being strong, lightweight, and resistant to impact, polyethylene is helpful when moisture resistance and low cost are the top priorities.

Advantages of Injection Molding for Automotive Applications

There are a host of advantages of injection molding for applications in the automotive industry.

Accuracy and Repeatability

High degree of accuracy and repeatability makes injection molding ideal for the automotive manufacturers to produce high-quality auto parts. It is crucial to be able to produce identical parts in the automotive industry. A large number of identical parts that meet extremely tight dimensional tolerances can be produced with automotive injection molding.

Fast and Efficient Manufacturing Process

Injection molding is a fast and cost-effective manufacturing process suitable for the mass applications. Injection molded auto parts can be produced quickly and efficiently. Generally, the parts can be produced within minutes due to the use of injection molding.

High Precision and Surface Finish

Injection molding is ideal for the production of auto parts with excellent surface finishes. The injection molded parts can be smooth and free of defects. Many finish options are available for manufacturers to produce parts, such as glossy, rough, or matte.

Material Availability

A wide range of polymers can be used for various automotive applications. These include ABS, polypropylene, acrylic, acetal, nylon, polycarbonate, and more. The production of automotive components can be fully in accordance with customer specifications in this way.

Color Options

With the use of injection molding in the auto industry, parts can be produced with various textures and colors. Different from other processes, injection molding is characterized by mixing dyes with the raw material prior to manufacturing. After the molding is complete, there is no need for further painting or tinting.

Automotive Injection Molding Applications

Injection molding services are gaining popularity in the automotive industry, because it can be used to manufacture quality plastic parts in large series. Common applications include:

Exterior parts

Bumper mold
Grille mold
Wheel cover mold
Fender mold
Headlights mold

Interior parts

Door panel mold
Dashboard mold
Glove compartments mold
Center console mold

FAQ

1.What is the best material for injection molding automotive parts?

Different materials have their own characteristics, and they can be used to manufacture different automotive parts. It can not make a definite conclusion to tell the best material. However, the most widely used plastics are PP, PU and PVC, both of which can be used to produce seating. Echofast can help you select a suitable material for your automotive parts to meet your customized needs.

2.Can injection molding be used for automotive prototypes?

It is closely connected with your required quantity. It is possible that manufacturers make rapid tooling for a low-cost run of molded parts for a hundred parts or so. However, the use of specialist prototyping technology like additive manufacturing is more meaningful for just one or two units of a prototype. This because the technology brings about fewer up-front costs.

3.Can metal materials be used to make injection molding automotive parts?

No, injection molding is not compatible with metals. Polymers can be injected into the mold, such as PU, PA, and ABS. Die casting is a great alternative when it comes to metals. Manufacturers can produce automotive parts like engine blocks and cylinder heads with die casting. Moreover, CNC machining is a popular process used in the automotive industry.

4.What is the difference between automotive die casting & automotive injection molding?

On the one hand, automotive die casting uses raw materials while automotive injection molding is done with plastic and and polymers. On the other hand, their processes are different. In automotive die casting, we first heat the metal until it melts, and then the forces inside a mold where it solidifies. While in automotive injection molding, we first heat a plastic polymer until it reaches a highly plastic condition. Then, it is pushed to flow under high pressure into the cavity of a mold, where it hardens.
