2K injection molding

2K injection molding: product injection molding with 2 different plastic materials or 2 colours : efficient and economical.

Where the K come from?

The K in ‘multi-K’ comes from the German word for component – “komponente”. So, if you see a reference to 2K or 3K moulding, it simply means that two or three different materials, or components, are used in the moulding process. Materials commonly used include thermoplastics and thermosets, plus liquid silicone rubber.

For certain products we need 2 injection steps for injection moulding. We call this 2K injection moulding. With 2K injection mold, two materials with different properties, colours or levels of hardness are processed into one end product in one injection moulding process. This saves costs.

With the 2K technique a possible assembly step is prevented. The choice for a 2K or 2-component injection moulding process is primarily based on a cost advantages, design features or aesthetic preferences.
