2K injection moulding can inject with 2 different plastic materials or 2 different colours. It will more efficient and economical. For certain products we need 2 injection steps for injection moulding. We call this 2K injection moulding. With 2K injection moulding, 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.
