RFP Title

 

Non-Contact Dispensing of Highly Viscous Fluids with High Precision, and Low Waste/Stringing
RFP Description
NineSigma, representing a Global Dispensing Corporation, invites proposals for systems, components, and methods to enable the non-contact dispensing of highly viscous fluids with high precision and accuracy, with low waste and no stringing.
Background

Highly viscous and non-Newtonian fluids can be challenging to transport, package and dispense due to their unique properties.  Many molten polymers are non-Newtonian fluids, as are many commonly found substances such as syrup, honey, adhesives, starch suspensions, paint, blood, and shampoo.  Many of these materials are sticky or fiber forming.  Often times, custom components are needed to handle the particular properties of the fluid to be dispensed.

 

A common strategy to increase the ease of handling a highly viscous fluid is heating to reduce viscosity.  While this can increase the ease with which these liquids can be handled, they still have a tendency to string when dispensed.  This stringing increases waste, errant dispensing, and cleaning time, while decreasing speed and final product quality.  NineSigma’s client is seeking systems, components, methods and expertise to enable the non-contact dispensing of highly viscous fluids with high precision and accuracy, with low waste and no stringing.

 

Key Success Criteria

The successful technology will:

  • Prevent fluid stringing, improve dispense cleanliness (leads to Improved product/process quality)
  • Stated objective within the following typical conditions:
    • Dispensing of a highly viscous fluid (500-2000 centipoise (0.5 – 2 Pa*s))
    • At 20-50 Hz
    • Typical substrate speeds 50-500 ft/min (15 – 150 m/min)
    • In bead patterns approximately 1/8” x 3” (3 x 75 mm)
    • At temperatures 250 – 350 F (120 – 177 C)
    • Will work with multiple viscous liquids
  • Be applicable to a manufacturing environment

 

Possible Approaches

Possible approaches might include, but are not limited to:

  • Novel valves, pumps, dispensing heads, and other dispensing system components designed to reduce errant dispensing and stringing
  • Positive displacement, jetting, and other dispensing systems

 

 

Approaches not of Interest

The following approaches are not of interest:

  • Fluid formulation alterations

 

 

Items to be Submitted

Your response should address the following:

  • Non-confidential description of proposed viscous liquid dispensing technology, system or components including:
    • Mechanism of stringing and waste prevention
    • Operating speed capabilities
    • Temperature compatibility
    • Ability of system or components to facilitate the deposition of defined patterns and demonstrate quality
    • Ability of system or components to operate in a manufacturing environment
  • Technical maturity of the approach (concept, prototype, ready to commercialize, commercialized)
  • Team description and related experience
  • Intellectual property status
  • Proposed collaboration type
  • Etc.
