One of our most outstanding capabilities is the simultaneous injection of LSR in combination with technical plastics, 2C LSR technology. In what is commonly referred to ask 2K, 2-shot, multi-component injection molding or co-injection, our LSR experts employ highly advanced and sophisticated tool and process engineering to develop the most innovation solutions, combining two, three or more individual materials into one fully bonded, robust component.
Advantages of 2C LSR Technology:
Enhanced processing options for more hygienic designs
Trelleborg Sealing Solutions is at the forefront of tool, process and automation technology for 2C or two shot liquid injection molding. 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.
