Pattern Piping on Silicone Rubber

Facts and Feasibility

  • Pattern Piping is a surface treatment technique.
  • Multi-color: pitch of 0.35mm to 0.40mm, depending on the design.
  • Complicated pattern
  • Piping: thickness of 0.70mm to 0.80mm; width of 0.35mm to 0.40mm.
  • Sharpness of tip-top: Obtuse angle is preferred with a width of at least 0.35mm.
  • Maximum of 3 layers of colored stack-up.



  • It is due to infeasibility of mold manufacturing to capture any undercuts.
