Enabling solutions for challenging applications



Combining different materials to a fully-bonded solution offers new possibilities in design and size for the most complex applications. Additionally, multicomponent products can minimize risk and increase hygiene for the component and the complete assembly, while reducing total cost-of-ownership.To get more news about 2k injection moulding, you can visit asm-mold.com official website.

Trelleborg Healthcare & Medical offers fully-bonded, molded combinations from a full range of engineered and high-spec polymers, including silicones, elastomers, thermoplastics, TPEs, and metals.
One of our most outstanding capabilities is the simultaneous injection of liquid silicone rubber (LSR) in combination with engineered plastics, Multicomponent LSR Technology. In what is commonly referred to as 2K, 2-shot, multicomponent 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.
Enhanced processing options for more hygienic designs

Trelleborg Healthcare & Medical is at the forefront of tool, process and automation technology for multicomponent LSR liquid injection molding. In a fully automated and closed loop system, either a combination of thermoplastic and LSR or two dissimilar grades of LSR 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, LSR is injected over either a thermoplastic or metal component to create a fully bonded part.The resulting design of sealing element proved to be highly cost effective. Total cost was reduced by eliminating assembly cost and risk and using a fully automated process. The design enabled an effective sealing solution within smallest geometries. The avoidance of dead space leads to higher hygiene with a highly reduced potential for bacterial growth. The component proved highly effective, and the same concept is being used across the customer’s product range.
