Two and More Component Solutions with Two Shot Injection Molding
Increasing cleanliness and hygiene with 2C LSR technology
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 as 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:
Offers designers much more latitude in design solutions
Can integrate multiple components into one fully-bonded solution
Single component is more robust than an assembly of individual parts
Provides lighter weight components
Risks and costs associated with secondary assembly can be avoided
Lowers cost by reducing the number of components in the customer’s supply chain
Increases cleanliness and hygiene by eliminating dead space and potential bacteria growth in the finished product
Enhanced processing options for more hygienic designs
Trelleborg Healthcare & Medical 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 Healthcare & Medical is overmolding. Here, Liquid Silicone Rubber is injected over either a thermoplastic or metal component to create a fully bonded part.
