High Quality Process for Pilot Runs, Low-Volume Production, and Bridge Tooling
Overmolding is a manufacturing process that involves molding two or more materials together to create a single component.
This process is used to improve the product’s functionality, aesthetics, and durability by incorporating different materials with varying properties into a single part. Overmolding can also be used to create a soft-touch grip or provide additional protection to electronic components.
The two-shot molding process is one particular type of overmolding. Nonetheless, at XTmade, we distinguish between these two. We usually refer to the overmolding process as an injection molding process that requires two injection cycles to complete.
Our team of experienced engineers and technicians work closely with our clients to select the most suitable materials and develop the optimal molding process for their project.
XTmade takes on the challenging overmolding applications. From overmolded medical devices to industrial applications, plastic overmolded components provide superior performance. By overmolding plastic onto or into metal, or plastic onto plastic we are able to create a more-consistent and higher-quality product with superior performance. In addition, it can eliminate complicated assembly and post-molding processes.
With our expertise, we are able provide design feedback for your challenging overmold applications. Our engineers will work with your team to offer solutions that optimize your design concept.
Overmolded products provide:
Of note, it is important to ensure that the plastic material for overmolding is chemically compatible with the substrate. When the overmold material does not chemically bond well with the substrate, the two materials can be mechanically bonded by incorporating holes or ribs on the surface of the substrate.
SPI Finishes
Range of finishes from Grade 3 diamond / high polish to 320 stone low polish. Finishes include: SPI A-1 SPI A-2 SPI A-3 SPI B-1 SPI B-2 SPI B-3 SPI C-1 SPI C-2 SPI C-3 SPI D-1 SPI D-2 SPI D-3
As Molded
No secondary polishing or grinding. Part will show tooling marks.
Other Mold Texturing
XTmade can match other mold textures upon request.
Overmolding involves molding plastic on plastic or plastic on metal to create a high-strength bond between the injection molded part and the overmolded part. As everything happens in a single operation, the need for assembly is eliminated. Although, this process may sound similar to two-shot molding, its single step process sets the two appart.
Common applications include creating two-tone aesthetics, gaskets and seals, and adding grips and buttons or hardware components to plastic parts.
XTmade works with leading manufacturers from different industries to support growing demands and streamline their supply chain. The digitalization of our custom injection molding services helps more and more manufacturers bring their idea to products.
We offer high standard overmolding services, support low volume manufacturing, fast delivery, and quick respond within 24 hours.
