Tungsten Disulfide (WS2) is an excellent coating for bearings where conventional lubricants can not be used or where the application requires the insurance of a permanent lubricant for extended wear life as in gear motors or transmissions. From miniature bearings used in dental hand pieces to large bearings for electrical power plants, the WS2 low friction coating extends wear life 2 to 5 times. Bearings with the WS2 coating applied by Micro Surface will have a blue-gray color.
Injection Molding Coating
  • All Mold Components that Contact Resin
  • Slides
  • Gibs
  • Inserts
  • Investment Casing Tooling
Improves Resin Flow & Mold Release 3 to 9% and increases productivity from 4 to 8% on average. Does not transfer to finished parts and provides longer lasting release than alternitives such as mold spray.
Automotive
  • Main Enginer Bearings
  • Rod Bearings
  • CV Joints
  • Transmissions
  • Differentials
Automotive parts coated with Tungsten Disulfide have lower friction which in turn provide longer wear life, reduced squeaking and noise, better gas milage and reduced fuel costs by requiring less energy.
Gears
  • Office Equipment
  • Pulp & Paper Handling Devices
  • Dry Lube for Clean Rooms
  • Automotive Transmissions
  • Rear End Differentials
  • High Load Heavy Equipment
  • Generators
Gears coated with Tungsten Disulfide exibit lower friction and as a result have a longer wear life.
Ball Screws
  • Thompson Shafts
  • THK IKO
  • NSK Linear Actuation Devices
Ball screws coated with Tungsten Disulfide run smoother from having lower friction and as a result will have longer life.
Shafts
  • Motor Drives
  • Internal / External Spline Shafts
  • Acme Threads
  • Dental Motors
  • Medical Motors
  • Turbine Engines
Shafts coated with WS2 have longer life because they are run smoother with less friction.
Wear Plates & Gibs
  • Injection Molds
  • Canning Machines
  • Tooling
Wear Plates & Gibs are able to function at high temperatures with a lower Coefficient of Friction extending wear life.
Chains
  • Roller Chain
  • Link Assemblies
  • Glass Plants
  • Paper Mills
  • Food Processing
  • Clean Rooms
  • Machine Assembly
Chains coated with Tungsten Disulfide are able to run without wet lubrication and also benefit from lower friction.
Valves
  • Servo Valves
  • Solenoid
  • Needle
  • Metering Valves
  • Ball Valves
  • Automotive Fuel Injection Systems
  • Diesel Hydraulic Valves
  • Nuclear Systems
Tungsten Disulfide coated Valves benefit from lower friction and in turn longer wear life.
Hardware, Connectors, & Disconnect Parts
  • Stainless Steel Components
  • Hyrdaulic, Fuel, & Air components where galling is a problem
After being coated with WS2 hardware has lower friction making it easier to assemble and disassemble and also prolongs wear life.
Cutting Tools
  • End Mills
  • Roughing Mills
  • Jig Reamers
  • Drills
  • Taps

Spiral Flow & Mold Release Improvement

A sprial flow study conducted by Western Washington University showed improvements of 3% to 9% in resin flow following Tungsten Disulfide (WS2) coating. The study was conducted to quantify flow enhancement afforded by the Tungsten Disulfide (WS2) coating when applied to injection, blow and extrusion molding/tooling. This return on investment to customers is experienced in improved product quality due to reduced operating pressure and temperatures, as well as significantly lower operating costs resulting from faster cycling and increased tool life.
