The 2K or ‘two-shot’ injection moulding process opens a world of possibilities for component performance and/or cost reduction. Simply put, it allows us to combine multiple polymers in a single process, creating individual parts that perform multiple functions.
The advantage of 2K compared with over-moulding is the first material injected is still hot and clean, enabling the best possible bond, and a much-reduced risk of burning.
Because of the chemical bond created between the two materials, outstanding adhesion is achieved; all without the thermoplastic portion requiring a chemical pre-treatment. The outcome of this is both an efficient and cost-effective process.
COBA Plastics Moulding is already working with existing customers on some exciting product lines in the automotive and homeware sectors.
One of the most in-demand functions for a 2K part is when the rigidity of one material such as nylon is required for structural integrity, whilst a second softer material allows flex or can act as seal between the component and its surrounding in the finished product.
