According to a report by Grand View Research, the global injection molding market is expected to reach $ 423.7 billion by 2030 up from 284.7 billion in 2021. This growth is partly fueled by the variety of injection molded parts available and their diverse applications across many industries.

Here, in this article, are some of the most common injection molded products and how they’re used to solve everyday problems from simple parts such as bottle caps to large car components. Read on to discover the many uses of injection molding, and how you can utilize it for your project.

How Injection Molding Works

Before the list of injection molded parts, it’s important to understand how the technology works. This process is accomplished by feeding a material, such as molten polystyrene, into an injection mold. The molten plastic then fills the mold and solidifies once cooled.

Injection molded parts are impressive in their accuracy and repeatability with minimal waste or imperfections. As such, they are ideal for mass production. Because injection molded parts can be made from a variety of materials with different colors, textures and flexibility, they are hugely popular in many industries.

Injection Molded Parts

Injected molded parts can be found being used in broad range of industries, including automotive, aerospace and healthcare. In these applications, these products offer the advantages of strength, durability and precision. Now let’s look at some of the most popular injection molding applications and parts.

7. Injection Molded Optics

Injection molded optics include lenses and other optical components. This type of injection molded part is used in a variety of applications such as cameras, eyeglasses etc.

One of the most common examples of injection molding applications in optics is the Fresnel lens. A Fresnel lens is a thin, flat plastic sheet with concentric circles cut into it.

Fresnel lenses focus light and provide a wider angle of view than traditional spherical lenses. These injection molded lenses find application in many products ranging from traffic light lenses to automotive headlights.

Injection molding lenses, besides providing a cost-effective way to manufacture optical products, also ensure lightweight products that can easily be produced, which means a lot when it comes to mass production.

8. Injection Molded Electronics

Injection molded electronics are becoming increasingly popular in a range of industries, such as consumer electronics, telecommunications, medical devices and aerospace.

Injection molding product examples in this application include electronic enclosures such as those found on cell phones, tablets and other consumer electronic devices.

Lightweight in nature and with excellent in strength, injection molded structural electronics offer an ideal solution for various components.

This process also allows for special details, such as logos and other decorative features. In addition, injection molding is capable of meeting tight tolerances which are required for electronic enclosures and components.
