Questions About Two-Shot Injection Molding
What materials are best for two-shot injection molding?
The two-shot injection molding process combines two different plastic resins in one machining cycle. To realize the full benefits of this process, you should choose two compatible materials that can form a molecular bond while simultaneously meeting the functional requirements of your part. Learn about the most common two-shot injection molding materials in our Two-Shot Design Guide, or contact us if you need help choosing compatible materials.
What design considerations should be made for the two-shot injection molding process?
Two-shot injection molding is the ideal process for complex parts. As such, part design often requires a high level of refinement and sophistication. That’s why we’ve developed a Two Shot Design Guide. It provides the foundation you’ll need to start designing for the two-shot molding process.
How much does two-shot injection molding cost?
Two-shot injection molding eliminates the need for secondary processes such as welding and assembly. As such, piece prices tend to be lower for two-shot molded parts compared to multi-component single-shot assemblies. The tooling for two-shot, on the other hand, tends to be more complex and costly than single-shot. Therefore, two-shot injection molding is most cost-efficient for high-volume productions.
