The Advantages of Double Injection Molding

If you are thinking of setting up a manufacturing company, it is important that you know the best ways to mass produce your products in record time. Why not try out double injection molding? It is a mass production process that could really speed up your production lines. What sets it apart from other production methods though? What advantages could it offer your production lines? Here are the key advantages of double injection molding.

1. It is Cost-effective

One of the best things about double injection molding is its relative cost-effectiveness. Compared to other mass production technology, there is very little material wastage. Remember that double injection molding is extremely accurate. This means when you create copies of your products, there will be fewer chances of errors occurring. You could really save up on materials, and it won’t slow down your production process in the long run. This allows your production lines to work without any interruption.

The main reason why the double injection molding is so efficient is because the process takes only one machine cycle. The main principle of double injection molding is that once the first mold is filled, it is rotated in order for the second mold to be attached to the product. The entire process is time-saving and could endure that more products could be made in record time.

2. There is a Beauty in its simplicity

As advanced as double injection molding might seem, it is actually quite a simple process. What’s incredible about the product, is that it is very easy to use, and assimilate into your work processes.

Double injection molding is very easy to teach your employees, and is a game-changer when it comes to the efficiency of your production lines. There is also the fact that you don’t need to change your whole work process to have it benefit you. It just adds a great deal more efficiency to your production lines.

3. It produces high quality products

Double injection molding is a relatively new manufacturing method, and it allows you to enhance your product’s overall quality.

What really sets double injection molding apart from other molding applications is the exceptionally strong bond that it could create. This makes any product made from the double injection molding process so much more durable and long-lasting.

Aside from double-shot molding, you should also invest in robot arms to fully complement the molding process. Once the plastic parts are done, robot arms could be used to remove the parts and assemble them with the other parts. As a rule, it is important that you have your molds work with robot arms for full effectiveness.

4. It has incredible versatility

Yet another aspect of double injection molding that is worth mentioning, is its incredible versatility. Whether you are mass producing plastic buckets, pails, or other types of household objects. The product does not need to be of a simplistic design either. Due to its incredible accuracy, you could also mass produce finer quality products, without any added cost or time.

There is also a fact that double injection molding allows you to mix both hard and soft polymers for a better outcome for any product, no matter how small it may be. This process is so efficient and multifaceted that you could use multiple materials that usually could not be bonded by other melding processes.

5. Easier To Control Product Outcome

Double injection molding is a very efficient and accurate manufacturing method. This accuracy makes it so much easier for you to control the final outcome of your product. Remember that the double injection molding process is extremely efficient, and usually has a great end result.

It is so accurate that you could minimize the number of misalignments in your products to a great degree. There are fewer instances of breakages or air bubbles on the final product.

Due to the efficiency of the double shot injection molding technology, it is very easy to get careless. However, there might be times where there are holes or dents in the final product. In this case, it is important for your employees to do a quick visual inspection of the product. As a rule, you should install LED lighting all over your production lines. This will make it easier for them to spot any potential imperfections to the final product.

6. It creates a more aesthetic design

One of the key features of using double injection molding is that it allows you to create extremely detailed designs. Remember that the main principle of double injection molding is that the hot plastic is injected into specially made grooves. This means that as long as you have a master mold to follow, your company could still mass produce highly detailed products without any trouble at all.

One of the best examples of double injection molding is RYD. It is a well- known company that sells top quality molds at the best prices possible. By investing in RYD, you could make sure that your  plastic constructs come out perfectly. If you are interested in purchasing RYD molds, you should check out the full two shot molding design guide to know more about the product.

7. More ergonomic designs

Aside from giving you a more aesthetic design, you could also create a product that has a more ergonomic feel and design. This is possible because the process allows for the use of soft-touch surfaces. This results in the products having a more handy and efficient feel. This feature is relatively useful for hand tools and other handheld products.


If you want to speed up the production process, you should try out double injection molding. By knowing the advantages of using double injection molding, you’ll know why it is such a great mass production option.
