What is Surface Rotational Friction (SRF)?

When the motor in PostProcess machine starts, a vibratory motion is initiated, moving whatever media/part mixture is sitting within the part envelope in a circular motion along the Y (vertical) axis. While the parts are suspended, the media/detergent mixture will rotate due to the circulating motion. This motion will ensure uniform exposure of the part to the media/detergent mixture and provide consistent results. This summarizes the Rotational component of the SRF technology. The Surface Rotational Friction would not be possible without its three main components:

• Proprietary Detergent
  • The proprietary detergent was designed by PostProcess chemists to optimize the mechanical, abrasive energy provided by the media. The detergent ensures the additive manufactured part being processed can circulate through the media and wash away any broken-down media or part material that accumulates during processing. By optimizing the media, consistency throughout the batch is ensured.
• Proprietary Abrasive Media
  • Extensive research has been done to test various abrasive media materials, shapes and sizes to determine the most effective combination specific to additive manufactured materials. For a one-size-fits-all approach, you can address multiple materials in one batch. Alternatively, specific material, density, shape, and size can be setup, and tailored to your part material and geometry.
• AUTOMAT3D Software
  • Controls the friction force that a part is experiencing to provide process flexibility
  • The software comes pre-loaded with four different customizable agitation settings
  • Process monitoring such as tank level, smart cycle times etc.
