Typical applications: product packaging, household items (tableware, trays, etc.), electrical (transparent containers, light diffusers, insulating films, etc.).

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.

Our two-shot injection molding company is ISO 14001:2004, ISO/TS 16949:2009, and WBENC certified. View our Certifications page.

Our two-shot injection molding company is located in Bad Axe, Michigan. You can drop us a note online, give us a call at 989-269-9791 or email us at plasticsales@geminigroup.net.

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.

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.

Our expertise lies in two-shot overmolding and insert molding. In addition, we utilize in-house secondary processes and high levels of automation to lower labor costs and improve accuracy and lead times. Our team can determine the optimal processes for your part.

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.

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.

Chemical and physical properties: Most commercial PS is a transparent, amorphous material. PS has very good geometric stability, thermal stability, optical transmission properties, electrical insulation properties and a very slight tendency to absorb moisture. It is resistant to water and dilute inorganic acids, but can be corroded by strong oxidizing acids such as concentrated sulfuric acid, and can swell and deform in some organic solvents. Typical shrinkage is between 0.4~0.7%.

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.

Make informed decisions before full-scale production with our rapid prototyping capabilities. We evaluate the design and identify potential issues quickly and cost-effectively to speed up the product development process.

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.

Injection mold process conditions:Drying: Unless stored improperly, drying is usually not required. If drying is required, the recommended drying conditions are 80°C and 2 to 3 hours.Melting temperature: 180~280℃. For flame retardant materials, the upper limit is 250°C.Mold temperature: 40~50℃.Injection pressure: 200~600bar.Injection speed: It is recommended to use a fast injection speed.Runners and Gates: All conventional types of gates can be used.

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.

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

QUANDA’s advanced extrusion technology and professional staff are able to provide global customers with high-quality engineering plastics and high-precision fabrication services.

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.

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.
