Micro-surface texturing enhances elastomeric seal performance without increasing injection pressure. This study developed a novel CFD method to simulate rubber flow in textured molds, proving manufacturing viability.

Area of Science:

  • Materials Science
  • Tribology
  • Computational Fluid Dynamics

Background:

  • Micro-surface texturing is a proven technique for improving elastomeric seal friction and wear.
  • Understanding the complex flow behavior of high-viscosity elastomers during injection molding is crucial for process optimization.

Purpose of the Study:

  • To evaluate the injection process of high-viscosity elastomeric materials into molds featuring wall micro-protusions.
  • To develop and implement a novel computational fluid dynamics (CFD) methodology for analyzing micro-scale and macro-scale rubber flow behavior.

Main Methods:

  • A novel CFD methodology was developed and implemented in OpenFOAM.
  • Micro-scale analysis quantified flow perturbations and calculated equivalent wall shear stress.
  • Reduced order modeling integrated micro-scale results into macro-scale simulations.

Main Results:

  • Simulations were performed for both an academic straight pipe and a real-world D-ring seal mold.
  • Textured walls were shown not to increase the required injection pressure in either case.
  • The manufacturing process is not adversely affected by the use of textured molds.

Conclusions:

  • The developed CFD methodology accurately simulates rubber injection into textured molds.
  • Micro-surface texturing of elastomeric seals is a viable manufacturing approach.
  • Textured seals can be produced without compromising the injection molding process or increasing energy consumption.
