The Consideration of 2K Injection Molding

The Consideration of 2K Injection Molding


We insist mold construction design, steel quality and precise manufacturing is the key to achieve molds with excellent performance. Our mold design principle is the mold must be durable, high efficiency and easy to do the maintance and manufacturing.To get more news about 2k mold, you can visit asm-mold.com official website.

There are a few variations of two shot moulding, including rotary platen, movable core, and overmold. The first two require a second injection unit, two runner systems, and two processes. The latter, in most cases, involves two separate molds—one for each material—but can also be run with one mold, two runner systems, and pick-and-place part transfer, either manually or with a robot.

2K injection mold and 2K injection molding process cost is higher than single injection molding, but the cost can be covered because of the assembly cost.

Deep Mould is pleased to advise you as a stong 2K injection mold manufacturing and 2K injection molding partner. We will work with you to optimize the part design, select the suitbale material, choose the cost effective 2K mold and two shot molding solution. We have the Engel 2K Injection molding machine with rotary plate in house for 2K mold trial and 2K injection molding production.

What’s the difference between 2k moulding and overmoulding?
A common question. Let’s first define overmoulding.

Overmoulding is also a type of injection moulding process that allows for the combination of two or more different materials into a single product. This usually includes a rigid, plastic-base component overlaid with a pliable, thin rubber-like thermoplastic elastomer (TPE) exterior layer or other materials using either a 1 shot (insert moulding) or 2 shot (2k) technique.
These are the main benefits associated with 2k moulding. While the counter argument and potential drawback is that the mould for 2k moulding and running the 2k moulding machine is more expensive… where high volume is needed, the overall cost and time can be significantly lower, thanks to a greater reduction in overall assembly and labour costs.

2k Moulding Design Considerations
Choosing the right material is very important. While 2k moulding certainly gives you more liberty in your creative expression, there are still fundamentals to adhere to. Take note of what plastics you are combining as some potentially may work better together than others. Factors such as viscosity and environmental protection are all things to consider from the outset.
If the 2 given materials are not compatible either physically or chemically – the end result will inevitably be a sub-par product… with deformation or other bonding issues like delamination where the different materials fall apart.

In summary, there are numerous other nuances to consider in the design process such as parting lines and the draft angle. However starting off in the right manner with the correct material choice will inevitably set the tone for the project. This is critical for every project, particularly when it comes to medical devices.
