Pros and Cons of Thermoset Injection Molding

Many people use the injection molding process to create a wide range of plastic parts and products. But they don’t understand all the benefits that are associated with the process. Moreover, many people think that thermoset injection molding isn’t right for them. But when you consider all the benefits and work with an expert to determine your product needs, this article will help you.

Knowing when to use thermoset injection molding is vital for any company that wants to be a top-notch injection molder. But there are so many tool types and molding processes out there. You can create a variety of products and parts, including electronics enclosures, automotive trim and appliances.

Thermoset injection molding is a cost-effective but complex process. Once you wasted time and money on a plastic injection molding system that’s not right for your application, it’s too late. Pros and Cons of Thermoset Injection Molding can help you avoid this problem by providing all the information. So, you need various types of injection moldings and making the process as smooth as possible.

If you’re looking for the best advice to help you choose the correct type of injection molding, then read this article.

Why Is Thermoset Injection Molding Suitable for You?

Thermoset injection molding is a manufacturing process that makes use of various thermoplastic materials. We can use it to manufacture plastic parts with complex geometry due to its efficiency, low cost, and high quality.

It can be used to make parts with complicated geometry. Because it is easy for the tooling designer to work on the mold design before manufacturing it. It also offers lower costs per part than other plastic manufacturing processes. Compared to blow molding and rotational molding, it has high efficiency and ease of use.

Thermoset injection molding has many benefits that make it suitable for different sectors. For example, sectors where you need high quality parts at low costs. It’s effectively what every company needs in the current economy where competition is fierce!

Pros of Thermoset Injection Molding

  • Incredibly versatile – Injection molding is useful for a wide variety of industries. These include automotive, medical, appliance, and electronics.
  • Precision – The molding process allows for very fine details to be intricately produced.
  • Great strength – Injection molding creates parts that are very strong and resistant to wear.
  • Low waste – Because the process uses very specific materials, it creates less waste than other manufacturing methods.
  • Quick turnaround – Parts made via injection molding need a very short timeframe.
  • Customizable – Parts are customizable which fit your individual needs.
  • Faster turnaround time because of the quick cooling.
  • More durable parts with fewer cosmetic flaws.
  • High precision for intricate designs.

Reasons Why Thermoset Injection Molding Isn’t Suitable

Thermoset Injection Molding is not suitable for all applications. Some of the factors that determine its suitability include:

The process is useful for low volume, high value products. If you are looking to make a low volume of products, Thermoset Injection Molding is the best option. But if you are looking to make a large quantity of products, it will not be the best option. Since it is expensive and complex.

The main reason for this is that there is no room for error in Thermoset Injection Molding. Thus, we should do many things correctly in order to achieve a good product. If any part of the process fails, then it will result in a bad product. Hence, your product will not be fit to sell on the market. Therefore, it requires skilled workers and advanced tools, which come at an extra cost too.


Cons of Thermoset Injection Molding

  • These can be quite pricey as precision-crafted molds are needed.
  • Injection Molding is a popular option for thermosetting products. Importantly, this process requires you use a mold-inject system. The Flash needs to be removed after the injection molding has taken place. If this step is not carried out, it could obstruct further post-processing processes. Also, it will make using your product difficult. Flash isn’t an issue with thermoplastics due to the higher viscosity of the liquid plastic.
  • It’s common for larger parts to be manufactured using thermoset injection molding. Medium to high volume projects are better serviced using transfer molding. When the smaller pieces are in consideration, thermoset injection molding isn’t the best choice.

Final Words

Thermoset injection molding is a process that companies are using for manufacturing plastic parts. This process is beneficial for creating a lot of different things from packaging to automotive plastics. Also, we see this process in operation for creating parts that are used as safety and security devices.

The benefits of thermoset injection molding are numerous. This process creates accurate and repeatable parts. It is ideal for medical equipment and automotive parts.

However, thermoset injection molding does have some drawbacks.  It requires more expensive equipment and more complicated mold design processes. We hope you’ve enjoyed this blog about thermoset injection molding.
