Overmolding Technology for Fluid Connection

Overmolding is an injection molding process in which one thermoplastic material is applied over another material to form one single part.  Overmolding can be applied to a wide range of thermoplastic materials and is increasing finding its way into the single-use technology market as the suppliers realize its potential benefits to single-use fluid path connections, such as increased strength, protect and improve a part or end product, while reduing cost, labor and materials.

Advantages of Overmolding

  • Improved component reliability by eliminating the needs for secondary steps (e.g., bonding, connection, assembly), therefor reduce operation and labor costs in manufacturing process.  
  • Overmolded components ensure proper alignment, provide integrally bonded connection with improved strength, realibility and product integrity.
  • Improved design flexibility, part strength and functional performance.
  • Elimiate potential bio-engress that can occur with use of cable ties and crimps.
  • Increase the productivity by reducing time, preventing product loss and contamination.

Meissner BioLink™ Modular Overmolding Technology              BioLink™ modular overmolding consists of two basic components: (1) lengths of BioFlex® TPE tubing with overmolded unitized end-fittings, and (2) polypropylene modules and filter adaptors injection molded out of the exact same resin as the bulk of filter product portfolio. All connections are created via automated welding processes that result in permanent thermal bonds between fluid path components with a smooth inner bore.  Learn More.
