There are a few additional components that are often utilized within the plastic injection molding process, and one particular category that’s useful in a few different industries is that of inserts. There are several different insert types that might be used depending on project specifications, and one that’s especially notable is the threaded insert.

At EnviroTech Custom Injection Molders, we proudly provide plastic injection molding solutions for clients across numerous industries that may benefit from threaded inserts, including automotive solutions and many others. What are threaded inserts, how do they compare to other plastic injection molding part inserts, and what are their key benefits and uses across industries today? Let’s have a look.

What Are Threaded Inserts?

For those just learning about them, threaded inserts refer to small parts that are meant to be inserted into a hole in the plastic part during the molding process. These inserts will often be cylindrical in shape, though they can also come in a variety of other shapes and sizes depending on the application.

What makes threaded inserts unique is that they have some form of threading built into them; this helps them to hold onto the plastic part securely once it’s been inserted. These inserts, unlike other types, are specifically meant for things like screws, bolts, and other items to be inserted into the molded plastic part.

Advantages of Threaded Inserts

Threaded inserts have a few distinct advantages when compared to other types of inserts, such as those that are used for mounting or alignment purposes. Firstly, they can provide a stronger bond between the plastic part itself and whatever item is being inserted, making them especially useful in applications where strength and durability are of paramount importance.

Additionally, threaded inserts often require minimal extra effort on the part of the designer during the injection molding process; they can be quickly added to a design without having to worry about finding additional space for them or if they will fit properly. This makes them an attractive choice for those who need to keep their designs slim and efficient.

Not only is general durability important, but so is the fact that threaded inserts can be repeatedly used in the same application without any issues. This makes them a great choice for applications that involve frequently swapping out or replacing parts, especially those within the automotive industry.

Finally, threaded inserts can also be cost effective when compared to other types of plastic injection molding inserts, making them an attractive choice financially as well as in terms of performance. They often cost far less than many other alternatives and can still provide a strong hold and excellent performance over the long term.

Uses for Threaded Inserts

Threaded inserts are an ideal choice for lots of different applications, but they’re especially popular in industries such as automotive and aerospace for their durability and cost-effectiveness. In terms of the automotive industry, threaded inserts are often used in things like engines, brake systems, suspension components, and other parts where strength and reliability is of paramount importance.

The aerospace industry also makes ample use of threaded inserts due to their light weight and ability to provide a secure hold for items such as blades or fasteners. They’re also commonly used in applications related to medical devices and other equipment where precision is key.

Another major industry where threaded inserts are found is in electronics. For instance, they can be used to provide a secure hold for components like capacitors and resistors in circuit boards.

Important Factors When Choosing Threaded Inserts

If you’re going to be utilizing threaded inserts as part of a given production run, here are a few important factors that our team will help you work through:

  • Type of plastic resin: Different types of plastic resins may require specific levels of grip strength, and the type of resin you use could affect the performance of your threaded inserts. This is a vital factor to consider when choosing the right threaded inserts for your project.
  • Shape: As mentioned earlier, threaded inserts come in a variety of shapes and sizes depending on the application. This can be crucial when it comes to making sure that they have enough room to fit within the part as well as providing a secure hold.
  • Thread size: The thread size will be important to consider as well, as this will determine the type of screws and fasteners that can be used with the threaded insert. It’s essential to make sure you choose a thread size that can accommodate any components you might need.
  • End-use application: It’s also important to consider the final use of the plastic part that will be utilizing threaded inserts. This is a key factor when it comes to determining the type and size of the insert needed, as some applications require more strength than others.

Once these factors have been taken into consideration, our team can help you find the perfect threaded insert for your project. Our experienced team can also help you determine the best technique for inserting the threaded insert into your part, making sure it will provide a secure and reliable hold for years to come. With our guidance, you can rest assured that your production run will go off without a hitch.
