Insert & Soft Touch Molding
Taurus Engineering creates parts using multiple materials and components without requiring assembly, or thermoplastic elastomer (TPE) over a rigid plastic or metal substrate for a soft-touch feel.
Soft Touch Molding

Insert Molding

Insert molding combines two or more components into a single finished part. A pre-manufactured component (e.g., metal or plastic) is placed in the mold cavity, and resin is injected around it to create a unified product. This process eliminates the need for additional assembly and is ideal for complex parts used in medical devices like connectors, infusion sets, IV catheters, valve swivels, and heat exchangers.

Taurus Engineering uses the best molding technique—whether injection, compression, or transfer molding—based on part complexity, production volume, and desired material properties.

Insert molding
Insert molding example: Medical Device Connector utilized in the Nero market with 21 overmolded gold plated 0.068″ diameter pins. A Multi cavity tool was designed to accomplish the specified assembly. Taurus Engineering designed automation around the process using bowl feeder systems accompanied with a robotic system placing pins into the mold for maximum productivity.

Soft Touch Overmolding

Soft Touch overmolding enhances product design with a soft, rubber-like surface for better grip and comfort. Using thermoplastic elastomer (TPE), we create a seamless bond between soft and rigid materials, improving functionality and durability.

Our process involves molding a substrate (plastic or metal), applying a TPE layer, and curing it to form a strong bond. Benefits include:

  • Comfortable, non-slip grip
  • Multi-color design options
  • Adds flexibility to rigid parts
  • Eliminates assembly steps
  • Ideal for medical components and devices
