Common Misconceptions About Injection Molding

Injection molding is a complex manufacturing process that has been used for many decades to produce a wide range of plastic parts. However, there are still many misconceptions and misunderstandings about the injection molding process. In this post, we'll explore some of the most common misconceptions about injection molding.


Misconception #1: Injection Molding is Only for Large-Scale Production

One of the most common misconceptions about injection molding is that it's only suitable for large-scale production runs. While injection molding can be used to produce high volumes of parts quickly and efficiently, it's also a viable option for smaller production runs. Advances in technology have made it possible to set up smaller, more flexible production lines that can accommodate smaller orders.


Misconception #2: Injection Molding is Only for Simple Parts

Another common misconception is that injection molding is only suitable for simple, uncomplicated parts. In reality, injection molding can be used to produce a wide variety of complex parts with intricate shapes and geometries. With the right equipment and expertise, injection molding can produce parts with extremely tight tolerances and complex shapes.


Misconception #3: Injection Molding is Only for Standard Materials

Many people believe that injection molding is only suitable for standard materials like ABS, polycarbonate, and polypropylene. While these materials are commonly used in injection molding, there is a wide range of materials that can be used in the process, including high-performance materials like PEEK and Ultem. These materials offer unique properties like high heat resistance, chemical resistance, and durability.


Misconception #4: Injection Molding is a Low-Quality Manufacturing Process

Another common misconception about injection molding is that it produces low-quality parts. In reality, injection molding is a highly precise and accurate manufacturing process that can produce parts with exceptional quality and consistency. With the right equipment and expertise, injection molding can produce parts with very tight tolerances and excellent surface finish.


Misconception #5: Injection Molding is Too Expensive

Many people believe that injection molding is too expensive for their production needs. While injection molding can have higher upfront costs than other manufacturing processes like 3D printing or CNC machining, it offers significant cost savings in the long run due to its high efficiency and ability to produce high volumes of parts quickly and accurately.


In conclusion, there are many misconceptions about injection molding that can prevent manufacturers from fully realizing the benefits of this highly efficient and versatile manufacturing process. By dispelling these misconceptions and understanding the true capabilities of injection molding, manufacturers can make informed decisions about their production needs and choose the best manufacturing process for their application.
