Applications of Plastic Injection Molding in Automotive Industry

Mercedes Benz cars

Although the automotive industry has traditionally been associated with steel and metal, plastic has become very important in the manufacturing of automobiles. This is because plastics are sturdier and, in some cases, durable than their metal counterparts. In fact, parts manufactured using automotive injection molding usually meet certain expectations more effectively than metal parts could.

Here, we go through some of the applications of plastic injection molding in the automotive industry.

Protection cases of electrical components

Vehicles have a number of electrical components, and they must be safeguarded from heat, water, as well as other external factors. Thanks to injection molding techniques, building protection cases using thermoplastics isn’t an issue. These cases are used as an external covering for sensors and electrical machinery present in the automobile.

Plastic provides immunity to any sort of physical damage (such as sudden shock) to the components.

Exterior components

Vehicle exterior components such as lamp housings, floor rails, door panels, bumpers, grilles, fenders, and other parts are all made using injection molding. Splash guards are an incredible example of how injection molded parts can be useful.

Flexible and durable materials like rubber are often used in the components that don’t just prevent splashing but shield the car from road debris.

Interior components

Most interior pieces of vehicles are produced using automotive plastic injection molding. This may include air vents, glove boxes, doorknobs, dashboard faceplates, interior surfaces, instrumentation, and other items. Moreover, injection molding is used for creating decorative plastic parts.

Under the hood components

In the last two decades, most under-the-hood components that were once made of metal have been replaced with plastic.

Robust polymers like PET, Nylon, and ABS are commonly used in these applications. On the other hand, injection molding is used to build items such as oil pans and cylinder head covers. Compared to metal parts, this approach didn’t just reduce costs, but the weight of the parts as well.

Increasing car comfort

Durable polymers improve driving pleasure. The plan is to increase consumer desire to purchase by enhancing driver assistance, intelligent technologies, entertainment systems, convenience features, interior finishes, handling performance, and reducing cabin noise while minimizing vibration.

4 Types of Injection Molding Technology

Image
From elaborate designs to simple products, injection molding can be used to make full production runs in the millions, a small number of prototypes, or anything in between. There are several injection molding technologies available to manufacture your next products. Here, we highlight 4 technologies that you may use to bring your product to life with higher quality in a shorter time. 1. Liquid silicone injection molding Thermoset is the majority of injection molding, meaning a part is created by injecting cold material into a very hot mold. In this process, the part is cured so it can never melt again. However, if you need a part to tolerate chemical agents or extremely high temperatures (as you might with certain car parts or medical devices), you may need thermoplastic injection molding , which uses liquid silicone frequently. 2. Metal injection molding Metals can also be injection molded. This new technology is considerably costlier than plastic injection molding and typically ser

Plastic Injection Molding: Benefits and Limitations

Image
One of the most commonly used methods of manufacturing identical plastic products in bulk is injection molding. However, like every process, it’s important to understand the specific design restrictions that must be considered to facilitate the obvious benefits of successfully producing high-quality, cost-effective parts. Here, we talk about the benefits and limitations of plastic injection molding: Benefits Low cost per part Although the initial high investment for the plastic injection molding tool is high, the cost per part is pretty low. While other plastic processing techniques may need a number of operations, such as polishing, injection molding can do everything at once. If you decide to do CNC machine apart, it may be costly. Injection molding will be your best bet if you’re looking to go into full production. High repeatability Once you’re done making mold tools, it’s possible to produce similar products repeatedly. The mold life of a decently made mold is quite lengthy – as

Double Injection Molding | PTMS

Image
Our company have much experience in  double injection molding  mass production since 2010. Double means double color, or double different plastic resin, it is also called double molding. In the fact, the cost of double parts is very expensive at this stage, because injection machine cost is very high, it needs double injection machine to produce the mass production. The machine has two hoppers for the different materials or colors, this cost is very expensive, but the double parts look very nice. The application of this injection is just limited, because it is not widely used in the different industries right now, so the cost cannot be cut down. The less, the little, the high cost we think. Here is a product made by double injection molding, it looks like a two-color basket, it is made of white hard glue PP and red soft glue TPE, the two different plastic resin is food grade, the soft TPE can be foldable, this part is portable and durable, but the mold is very simple, not very difficul
