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.

This breadth of experience enables us to evaluate multiple processes and materials and recommend the optimal combination for your unique application.

From concept to production, our tailored design and engineering capabilities deliver cost-effective solutions for two-shot injection molded parts. We have the experience and confidence to take full design responsibility or serve as a design partner.

Two-shot design can deliver a competitive advantage far above other molding processes, especially for complex parts. Learn the benefits of the process and explore the special design requirements needed to make it work in this free guide created by engineers, for engineers.

Our specialized press-to-press transfer technique allows us to mold 360-degrees. It’s ideal when your application requires molding over metal inserts such as fasteners and magnets or other substrates such as structural reinforcements.

Our two-shot injection molded parts contribute to the success of major industrial sectors, including automotive, lawn & garden, heavy equipment, and consumer products. Explore the wide range of uses for our two-shot injection molding solutions.

These are Injection molding products made from various functional engineering plastics, including fluoroplastic. With our extensive know-how, we can propose the appropriate molded product shape from the design stage onwards. We also respond to customer requests such as "I don't know what design is suitable for molding" and "I don't have time to design and draft."

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.

●We have a track record of launching over 2,000 products.●All processes from molding to inspection and packaging are carried out in a clean room. (Varies depending on size)●Since we do everything from mold design and production to molding in-house, we can provide faster and more accurate service.●We can handle sizes as small as 10mm x 10mm x 10mm to as large as 500mm x 500mm x 500mm. (These are approximate sizes.)●We can handle lots starting from 100 pieces. (Please contact us for details on size, etc.)●For quantities of less than 100 pieces, we can also provide PTFE machined products.●It is also possible to carry out cutting after injection molding.

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.

We’ve worked with hundreds of materials and additives, so we can accurately predict how processing will affect appearance. This expertise allows for precise color-matching and replication of design intent, enhancing visual appeal and brand identity.

There are hundreds of materials suitable for two-shot injection molding and thousands of ways to adjust, blend, and fine-tune them. Our material experts can help you choose compatible materials that will form a molecular bond while simultaneously meeting the requirements of your part.

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. Request a quote today to see if two-shot molding is the right solution for you.
