Scratch-free Surface Finishes

The Need

When it comes to specialized applications like superlative surfacing, finding a contract manufacturing partner that can reliably meet advanced finishing requirements can be a struggle.

At Pulse Technologies, we specialize in advanced manufacturing operations and possess in-house expertise to develop innovative approaches for complex device demands. One such example of this is the development of uniform, ultra-precise, and scratch-free surface finishes utilized in high blood flow devices such as heart pumps.

Heart pumps, which rely on efficient blood flow to prevent complications such as hemolysis, typically necessitate a surface roughness of sub-5 Ra. Consistently achieving this stringent specification can be challenging for organizations that lack expertise in advanced processing methods.

The Solution

To address these challenges, Pulse developed a proprietary scratch-free process that is consistent and scalable. While used thus far primarily for high blood-flow devices, we believe such surface finishes may also lend themselves to a myriad of other applications.

Benefits of Pulses’ scratch-free surface process include:

 

  • Precise and consistent surfaces with no machining lines
  • Surface profiles down to 0.2 micron Ra
  • An automated process that is repeatable and scalable
  • Can be used in conjunction with electropolishing
Let us give your device the perfect surface.
