Two shot injection molding / 2K molding
Increasing cleanliness and hygiene
- Eliminates dead space and potential bacteria growth in the finished product
- Eradicates the risk and cost of assembly
- Provides greater design latitude, e.g. flashless options
- Increases cleanliness and hygiene
Enhanced options for more hygienic designs
Trelleborg Sealing Solutions is at the forefront of tool, process and automation technology for 2K or two shot liquid injection molding, also referred to as a two component or 2-shot processing. In a fully automated and closed loop system, either a combination of thermoplastic and liquid silicone or two dissimilar grades of liquid silicone are co-molded into a bonded component that offers a wealth of benefits in both assembly and function of the finished product.
A second process option for two component parts, suited for lower production runs and commonly applied by Trelleborg Sealing Solutions is overmolding. Here, Liquid Silicone Rubber is injected over either a thermoplastic or metal component to create a fully bonded part.
