What is Overmolding?

what-is-overmolding
Overmolding is an advanced plastic injection molding technique used to combine two or more thermoplastic materials into a single, unified part. This process begins by injecting the first thermoplastic, known as the substrate, which forms the core structure of the product. A second material, called the overmold, is then injected either around or onto the substrate, bonding with it as the materials cool. The overmolding technique enhances the durability, functionality, and aesthetics of products, commonly used in high-volume production for industries that require high-performance parts, such as automotive, medical devices, and electronics.
 
At RapidDirect, we specialize in custom plastic overmolding to boost the functionality and visual appeal of your components. Our expert team and advanced technology deliver seamless bonds between materials, ensuring top-quality results.

Plastic over Plastic

Crucial for mass production, involves machining, and assembling durable molds from steel or aluminum to ensure precise and repeatable part geometries.

  • Aluminum and steel injection mold.
  • Achieves detailed geometries.
  • Ideal for mass production.

Rubber Over Plastic

Overmolding improves product functionality and aesthetics by fusing different materials into one part, adding features like soft grips and multi-color designs for enhanced usability

  • Improves strength and lifespan.
  • Combines different materials seamlessly.
  • Offers color and texture options.

Plastic Over Metal

Insert molding integrates metal or other materials into plastic parts during molding, enhancing strength and reducing assembly time for components with embedded features.

  • Reduces assembly steps.
  • Enhances component durability.
  • Lowers production expenses.

Tooling Solutions

Rapid Tooling

Get easy design feedback and validation through superior quality prototype tooling. Create small batches of plastic molded parts with excellent injection molding prototypes. We excel at manufacturing prototype molds within days to ensure you perform functional tests and validate market interest. 

Our molds with steel cavities and cores typically have a shot life of 1,000 to 5,000 shots and can be manufactured within two weeks.

Production Tooling

We create high-quality production molds for high-volume plastic parts production. With high-strength, durable tool steel material, our production tooling is suitable for producing hundreds of thousands of parts. We can vary materials and construction methods according to your unique requirements.

Our high performance steel tool is capable of enduring up to 10,000 shots, and generally parts can be produced within 3 weeks.

RapidDirect's Overmolding Finishes

Our SPI finishes range from Grade 3 diamond/high polish to 320 stone low polish. The available finishing options 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, and SPI D-3.
There is no secondary polishing or grinding, which means that our parts will display marks from the tooling process.
