What certifications do you have?
Our two-shot injection molding company is ISO 14001:2004, ISO/TS 16949:2009, and WBENC certified. View our Certifications page.
What materials do you work with?
We work with a variety of plastic resins. For a complete list, please visit our Materials page.
Who manufactures your tooling?
We design and manufacture most trim and fabrication tooling, as well as assembly fixtures, in-house. We’ll occasionally build prototype and production molds in-house, but we’ve found it’s usually more cost-effective to design in-house and partner with a dedicated, US-based moldmaker for the manufacturing.
My project requires an NDA. How do I submit that?
You can attach your NDA to our RFQ form or send it directly to plasticsales@geminigroup.net.
Do you offer molding options other than two-shot injection molding?
Two-shot injection molding is just one of our many plastic molding capabilities. We also specialize in:
- Profile extrusion
- Technical blow molding
- Compression molding (including Baypreg and Azdel)
This breadth of experience enables us to evaluate multiple processes and materials and recommend the optimal combination for your unique application.
In fact, 9 out of 10 of our largest customers purchase products from two or more of our processes.
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.
