Synthetic hydrocarbon grease is the safest default for most POM, PA66, and PBT gear systems, while silicone or PFPE options fit lower-load or extreme-environment programs.
Noise is usually driven by tooth profile error, backlash mismatch, alignment issues, surface finish, or housing resonance rather than by material choice alone.
POM, nylon, PBT, and PEEK each fit different load, humidity, temperature, wear, and regulatory conditions, so the right answer depends on the end-use profile.
Mold precision, shrinkage control, environment, wear, and stable molding parameters all directly affect backlash and long-term positioning accuracy.
Resin preparation, tool design, gate strategy, cooling, and validation discipline shape final tooth accuracy and repeatability.
Look for material competence, tolerance capability, mold validation steps, certification, lead-time realism, and application-specific evidence.
Cavity accuracy, steel choice, shrinkage compensation, cooling design, and dimensional verification determine whether the mold can hold stable gear geometry.
