Two-Shot Molding

Custom Silicone/Thermoplastic Molding Capabilities for Medical Device Manufacturers

Saint-Gobain, a world leader in the development of high-performance polymer products, offers an innovative, cost-saving solution for medical OEMs. Two-shot silicone-thermoplastic molding technology enables the development of medical device components that combine silicone and thermoplastic materials in one process.

Traditional molding involves separately molding silicone and thermoplastic components, then assembling them using secondary processing steps to create one medical device component.  Two-shot molding eliminates these secondary operations by combining materials in a single, molding cycle. This reduces tooling requirements—eliminating the cost and lead-time of a second mold and its validation—while also improving part-to-part consistency and overall performance.

Features & Benefits of Two-Shot Molding

We can help you design components to maximize the material property benefits of both silicone and thermoplastic and create a process that can mold them with extreme precision and reliability.

Reduced Cost
  • Reduced part handling & validation costs

Greater Design Freedom
  • Elimination of adhesives and assembly

Product to Market Faster
  • Reduced lead-time

Increased Bond Strength & Part-to-Part Quality
  • Leverage characteristics of Substrates that bond to silicone: polycarbonate, ABS alloys, PEEK (Non-BPA), polysulfone (Non-BPA), PBT (Non-BPA), nylon (Non-BPA)

Saint-Gobain Medical is an established and reliable brand around the world and that provides trust and security that they can deliver when it matters most.
