  • Reduce lapping times from hours to minutes
  • Reduce slurry usage and waste from gallons to pints
  • Achieve a reflective finish in a single step, eliminate hand polishing
  • Cleaner process, cleaner parts
  • Process a wide variety of materials

Why Engis?

  • Engis is a micronizer – we purify, precision grade, disperse, and custom formulate our slurries, where others are simply repackaging. We are unequaled in our ability to precisely characterize and control particle size distributions (PSD).
  • Applications expertise – our engineers can provide the full process recommendation for your part/material - not only the best slurry formulation but also the polishing machine, lap plate or pad, accessories, and process settings.
