Catheter Mandrels

Wytech specializes in precision grinding and machining solutions for complex geometry mandrels used as catheter manufacturing aids and tools ranging from various applications, including reflow to bonding, cutting, tipping, and welding.

Combined with our sister company, Mountain Manufacturing Technologies, we are your single source for R&D mandrels and production mandrels.

Common Mandrel Geometrics

Engineering of mandrel features can dramatically improve catheter assembly output and significantly reduce scrap by enhancing the precision of the catheter manufacturing process. Below are categories of common mandrel geometrics that assist in assembly manufacturing.

Design Features Include:

  • Eccentric
  • Flat
  • Grooved
  • Hollow Core
  • Notched
  • Shaped

We are adept at working with a variety of materials, including:

Wytech can manage the entire supply chain of your catheter mandrel needs. If your application requires a more lubricious surface finish, we will connect you with our preferred PTFE Coating Partner, Applied Plastics.
