2K injection molding, also known as two-shot or dual-shot injection molding, is a manufacturing process that combines two different materials into a single part. This technique involves injecting one material into a mold cavity to form the initial shape and then injecting another material on top of it to create additional features or enhance the properties of the part.

The Process of 2K Injection Molding
In 2K injection molding, the first shot is typically made using a rigid plastic material such as polypropylene (PP) or acrylonitrile butadiene styrene (ABS). This forms the base layer of the part. The second shot can be made with either another rigid plastic or a different material altogether, such as thermoplastic elastomers (TPE), thermoplastic polyurethane (TPU), or liquid silicone rubber (LSR).
The two shots are injected sequentially into separate cavities within the same mold. The first shot creates an initial shape while leaving specific areas open for subsequent injections. Once the first shot cools and solidifies, the mold rotates or moves to align with another set of cavities where the second shot will be injected.

Liquid Silicone Rubber Injection Molding
One of the materials commonly used in 2K injection molding is liquid silicone rubber (LSR). LSR offers several advantages, including excellent flexibility, durability, and resistance to extreme temperatures. It is often used for applications that require tight seals or soft-touch surfaces.
In the 2K injection molding process, LSR can be combined with a rigid plastic material to create parts with enhanced functionality and improved aesthetics. The combination of different materials allows for greater design freedom and opens up possibilities for creating complex geometries that would be difficult to achieve using traditional manufacturing methods.
Conclusion
Overall, 2K injection molding is a versatile manufacturing process that enables the production of complex parts with varying properties. By combining different materials in a single mold, manufacturers can create products that offer enhanced functionality and improved performance. Companies like JVTECH are leading the way in this field by utilizing advanced technologies and providing tailored solutions to meet their clients’ specific needs.
