The Benefits of Two-Component Injection Molding

2. Injection molding repair offers an extremely versatile range of manufacturing options, as the nature of the process means that it’s suitable for a host of part and product designs and types. Beyond the standard injection molding process, even more versatility and efficiency can be achieved via two- component injection molding.

3. Mixed materials Co-injection molding In what might be considered the simplest form of two-component injection molding, two materials can be fed into the injection molding repair machine simultaneously and mixed as they are heated. In co-injection molding, two full material shots are injected into the cavity, one right after the other, resulting in the materials hardening around each other while becoming fully bonded.

4. Bi-injection molding: Multi-shot molding: In this process, different materials are fed into a mold cavity at different points, through different gates. They begin to harden before their meeting point within the cavity, resulting in a layered effect. In multi-shot molding, a “layering” effect is achieved by injecting partial shots of material in sequence into the mold cavity. The materials neither mix nor harden around one another.
