What's the differences between 2K Molding and Insert Molding?

It is not so easy to understand the differences between 2K molding and insert molding.

So today let's figure it out easily.

2K molding: Two plastic materials are injected on the same injection molding machine, and this injection molding machine is a special machine which can inject two kinds of material,normally one is soft plastic and the other one is hard plastic. 

This injection molding machine will have 2 nozzles which the normal injection machine has only 1 nozzle. In general, this molding process is also called double-material injection molding. Usually, it consists of two molds, one half of which is mounted on the fixed plate of the nozzle side, and the other half is mounted on the rotating plate of core side half. The core half molds are exactly the same, but the two sets of cav half molds are indeed different. When the plastic injection of the first color is completed, the molds will be opened in the parting line, and the core half mold will bring the first product and rotates 180 degrees to reach the position where the second color needs to be injected. In this cycle, there will be a mold for a primary product and a secondary product in each molding cycle.

Insert Molding: sometimes called Fake 2k molding, two kinds of plastic materials are injected on different injection molding machines,this could be used with normal injection machines with only one nozzle.It means the parts have to inject totally 2 times.They are not injected in the same machine as 2K molding.When the first shot is completed,the parts have to move to the other machine,you may need use hands or robot to take them one by one put into the second mold. The second injection molding with be injected with the first insert part(so we call the first shot as an insert). Generally, this molding process is usually completed by 2 sets of molds and 2 sets of injection machine, without the need for a special two-color injection molding machine.

The above are the basic principles of making two-color injection molds.

Also the insert mold's cost will be much less than a 2K injection molding.

If you have big quantity of part request,you could consider to make the parts with 2K injection moldings.

If you have less quantity of part request,we suggest you could make it with insert molding,it is also called overmolding.

Triple-c is also a specialist in 2-component injection molding.

What is 2 components injection molding?

With this technology, two materials are combined in one mold. For example, materials with multiple different properties or materials in two different colors or hard-soft combinations. Think of the current modern white toothbrushes with a soft grip/handle;

The chemical bonding of the 2 components occurs because they merge into one another or because the first component is constructed in such a way that the second component bonds mechanically. Sometimes it is desirable that the two materials do not adhere to each other. As a result, play-free parts can be &#;mounted&#; in the mold. Our specialists will be happy to advise you on what is most feasible for you.

2K injection molding saves time and costs

One of the strengths of Triple-c mold maker department is the 2c injection molding (Two Component injection molding). We have a very advanced machine park that takes 2c injection molding to a higher level. With 2K injection molding it is possible to combine two different types of plastic in one injection molding process. This allows us to integrate multiple properties into one product: for example, layered products, combinations of hard and soft plastic or for making different color combinations.

The benefits of 2K injection molding

The technology two components injection molding makes it possible to produce a completely assembled product so that this part does not need further secondary processing . That means gains in the cycle time, a constant process, a higher degree of efficiency and the avoidance of manual insertion. And because the post-processing or assembly is not longer necessary, you can also save considerably on costs with 2components injection molding.
