A Guide into Sourcing Automotive Plastics

A Guide into Sourcing Automotive Plastics

For a very long time, alloys have overwhelmed the general material substance of a car. Nonetheless, in the most recent decade, because of new regulations and fuel costs, there has been a noteworthy move to utilizing lighter weight materials, most commonly plastics or composites. This ascent in the car plastics is because of the business’ push to diminish the general mass of a vehicle, which is being driven by government controls and benchmarks (CAFE), and fuel costs.

An acquisition professional should always remember the following things before settling on a plastic injection molding crew. Not only do all of the following affect the overall pricing of the component, but equally as important, they affect the quality.

Key Considerations

Car plastics present one of a kind and valuable properties, for example, sturdiness, solidness, recycle capacity, heat stability, strength, protection, design adaptability, and light weight. The most widely recognized applications for plastics in autos are with the inside, outside and motor segments since they offer a lighter-weight choice, while expanding fuel effectiveness. Plastics likewise enhance the look or style, diminish noise and vibrations (NVH), keep in heat, and so on. Plastics offer a more reasonable way to deal with a more maintainable vehicle.


To legitimately source a car plastic part, a plastic injection professional must consider and completely comprehend the procedure that the segment and application warrant. Many variables determine which process is worthy. These incorporate size, weight, shape, application, surface area, heat, stream, and so forth. The most well known plastic procedures for car applications, incorporate the accompanying:

Injection Molding

Injection molding is the most mainstream process utilized for car plastic segments. With this procedure, the plastic (in pellet frame) is put into a container which moves the plastic pellets into a warmed infusion unit, where it is pushed through a long chamber. The material is liquidized amid this procedure and solidifies in the wake of drying. For high-volume plastic segment programs, this is the prescribed procedure.

Thermoforming/Vacuum Forming

Thermoforming utilizes a plastic sheet, which is shaped with a form by applying air or through mechanical help. The pneumatic force utilized can be about zero psi, or a few hundred psi. At 14 psi, which is roughly proportional to air weight, the weight is made by emptying the space between the shape and the sheet. This is known as vacuum framing.

Blow Molding

At the point when the segment should be empty or have liquid move through, the blow shaping procedure is most useful for the application. A liquid tube is made with blow molding utilizing packed air, which explodes the tube and powers it to comply with the chilled form.

Pressure Molding

Pressure molding is the most well-known process utilized with thermosetting materials and is typically not utilized for thermoplastics. With this procedure, the material is crushed into its shape with the assistance of weight and warmth. At the point when the mold is shut and warmed, the material experiences a synthetic change that makes it solidify into the coveted shape. The temperature, weight, and time allotment used amid this procedure relies upon the coveted results.


The procedure of extrusion is normally used to make items, for example, film, ceaseless sheeting, tubes, profile shapes, poles, coat wire, fibers, cored, and cables. Similarly as with injection molding, dry plastic material is put into a container and bolstered into a long warming chamber. Toward the end of the chamber, the material is moved out of a little opening, or a die, in the state of the completed item. As the plastic leaves the die, it is put on a transport line where it is permitted to cool. Blowers are now and then used to help in this procedure, or the item might be submerged in water to enable it to cool.


In light of the use of the part, its nearness to a heat source, area on the vehicle, and process, there are an assortment of elite plastics that are broadly utilized as a part of the car business, and a plastic injection molder must consider the attributes of every while sourcing a plastic segment. The most common materials for car plastics include: Polypropylene (PP), Polyurethane (PUR), Poly-Vinyl-Chloride (PVC), Acrylonitrile Butadiene Styrene (ABS), and Polyamide (PA, Nylon 6/6, Nylon 6).


The car plastics industry is situated to grow exponentially in the coming years. Understanding the above key aspects will guarantee trust in sourcing choices and offer organizations an upper hand in settling on future choices. Despite the fact that these thoughts are perhaps basic, there are numerous plastic injection professionals today settling on key choices without considering every single potential alternative with regards to plastic preparing and material determination. A true plastic injection molding expert will invest the energy it takes to completely comprehend plastic applications, volumes, procedures, and materials before sourcing to best plan their organizations can supply for your project.

Automotive Plastic Injection Molding

Automotive Plastic Injection Molding

The automotive industry has profited much from the injection molding process. Formed plastic parts from the littlest segment to entire body panels of vehicles can be massed delivered utilizing Injection molding methods. Learn more from this slide show.

Plastic Injection Molds and the Automotive Industry

Plastic Injection Molds and the Automotive Industry

Vehicles have come a long way since they started, while some of the first forms of human transportation was nothing more than simple horse-drawn carriages as chariots, the development of new technologies soon led to cars, boats, motorcycles and trucks powered by engines. Even so, the development of plastic injection molds allowed for much growth in the automotive industry, and engine-powered vehicles have come a long way since their humble beginnings.

The First Cars

Henry Ford is widely seen as the first inventor to make cars that were widely accessible to the general public. However, the first cars tended to consist mainly of metal parts, predominantly steel. The main drawback of this was that these cars were heavy, meaning they had more weight for the engines to drag along, because of this, most older cars tend to have high fuel consumption levels.

Another major drawback of heavy steel cars was that production techniques didn’t allow manufacturers to think much about aerodynamics in order to minimize air resistance on a moving vehicle.

All of the above-mentioned things were some of the initial challenges faced by the first car makers.

Plastic in the Automotive Industry

In modern times, plastics are crucial in the production of almost anything you can think of, including cars. In the automotive industry, the main benefit of plastic is that it helps to make vehicles lighter, which helps to make cars more fuel efficient.

However, modern vehicles often merge the automotive industry with technology, and new cars often come out with features like built-in screen displays, rear view cameras and more. Most of these luxury features need plastic molded parts too, and so the amount of plastics in cars tends to become more and more, not only because parts that were previously made from steel (like bumpers and inside door panels) can now be molded from plastic, but also because new technological features necessitate the use of additional plastic parts.

In a world of advancing technologies, plastic has been a crucial ingredient in our modern success. This is no different in the automotive industry where improved molding techniques and the availability of new materials has made it possible for the automotive industry to advance in ways we previously would never have been able to imagine.

Automotive Injection Molds

The use of plastic in advancing technology is indisputable. However, few people stop to think about the process of creating plastic pats. The advances visible in society today have only been made possible through the use of precision-engineered plastic molds.

But plastic injection molds aren’t simply forms to pour molten plastic into. The production of a plastic injection mold that can produce parts for modern vehicles is a meticulous process. A mold that’s been made with care is one of the main things that will ensure that molded parts are free of defects. A faulty mold could result in problems such as a mold cavity that doesn’t fill, or dark lines on the molded part (among other possible problems that could occur). This is especially true with parts that that have curves, lines and other complex shapes that are commonly required in the automotive industry.

To prevent injection molding defects while producing plastic parts, automotive manufacturers simply need two things: a reliable molds that have been designed right, and the correct use of polymers in the mold. This is because using the wrong plastics, or even using the right plastics at the wrong temperatures could result in defects in the molded parts. And while it’s easy to change issues with polymers simply by using different plastics, or by changing the temperatures at which equipment operates, having a faulty mold changed would be a more costly.

Mold gates placed in the wrong areas, for instance, would be a difficult, costly problem to fix. Remember, molds have to be designed with their end purpose in mind. And in the case of plastic injection molding, the flow of the molten materials through a mold is an important thing to keep in mind while designing and making the mold.

In order to get a quality molded part that will live up to expectations, automotive manufacturers must begin with molds that can do the job right.
