2k injection moulding in practical applications : Special moulds with 2 product cavities
We build molds with 2 product cavities for this type of injection moulding. During the production process we inject plastic into one cavity of the mould. Once that has hardened, the mould rotates and we inject plastic into the other cavity, against the product that was formed in the first cavity.
The benefits of 2k injection moulding
With 2K injection melding, we can inject a plastic into the mild with one or more separate injections. This gives a very precise split line between the different materials, such as the difference in hardness of material or a difference in colour etc.
The 2K injection moulding technique can be more attractive from an aesthetic point of view because the 2 components fit together seamlessly as product can be made in 2 colours (2K) in one production process.
Because the 2K technology assembles assembly steps together into one injection moulding process, the cost price of your product is often lower.
User-compliant and tailor made products
The practical use is an important aspect in product development. Hard plastic is not always user-friendly. It is then possible to finish the product with softer edges or a complete soft plastic cover, which increases user comfort. When producing a soft seal in the second shot, products can be made fit for use in watertight applications etc.
The disadvantages of 2K
The one-time investment costs of 2k injection moulding are a bit more expensive when compared with a single stage injection moulding process. However, these costs are in most cases quickly recovered because assembly steps and hand labour can be eliminated.
Not all plastic combinations are possible because some plastics do not adhere sufficiently to each other.
GL Plastics, your injection molding partner and market leader for 2K injection mouldings
2K injection moulding offers many advantages with regard to more complex products compared to single injection moulding. It helps effectively reduce costs, reduce assembly time, combine material properties and make a strong connection between materials.
We will gladly calculate for you whether 2k injection moulding is the right solution for you, or if another option of injection moulding is more suitable for your products.
GL Plastics is happy to advise you as a strong 2K injection moulding partner. Both when selecting the suitable materials and when determining the optimum processing method. In this way we ensure that the end product exactly meets or exceeds your expectations.
