In Plastics, Precision Matters

Specially Formulated Material, Made with a Proprietary Process

There are hundreds of good polymer materials on the market. Sometimes good doesn't cut it.

Powercore has the highest dimensional stability of any polyamide currently on the market and  is the result of decades of perfecting a process based on laboratory testing and real world feedback. We've staked our reputation on providing superior components - they start with the right material for the job. Capable of AGMA Class 10+

Specialists in Plastic Gear Design Engineering

You deserve to work with the experts. For more than 3 decades we have built a reputation and a business by focusing on engineering superior plastic gears. In the beginning, we had to translate what was known in metals to work in plastics. Over the years we've developed our own calculations, software and polymer specific design methods to ensure you get the a get the right gear for your application.

Decades of Real World Operational Data

You can benefit from other's testing. With tens of thousands of machined plastic gears in operation in the most critical and demanding application in the world - we've learned a few things. Every time we enter a new application we build on our knowledge and update our durability calculations and software. With hundreds of thousands of real world data points we've taken the guess work our of plastic gear design and life calculations.

Cast In Metal Core

Metal hubs gravity cast in Power-Core allow for optimal bonding of the metal core to the plastic outer surface, this bond is optimized for how plastics react in real-world operating conditions and isn't achievable by any other production process such as extrusion, pressing or pressure molding. The metal core allows forces to be optimally transmitted to the working surface and ensures the metal hub doesn't separate from the plastic working surface, as is common in most plastic gears. The metal core allows drilled shafts and key slots to be finished with tolerance equal to steel.

Superior Dimensional Stability

AGMA Class 10+ gears. 

Power-Core has the lowest level of water absorption of all polyamides and thus the most negligible expansion properties. Power-Core has the highest dimensional stability of any polyamide currently on the market. Power-core also has far superior creep resistance to extruded or injection molded short glass fiber reinforced polymers and has extremely high impact strength even at temperatures below -50°C

Real World Material Reliability Calculations

Power-Core Gears can be calculated to last the necessary years for the application. Decades of data allows us to reliably estimate operating life of all our components. Power-Core® shows superior product life span and durability compared to other plastics.

  • High load bearing capacity
  • High abrasion resistance and product life
  • Exceptional wear properties in low lubrication and un-lubricated environments
  • the highest chemical resistance of all polyamides (pH range 2-14)
  • suitable for use over a wide temperature range from -40 °C to +100°C

White Paper: Polymer Gears Out Perform Metal Gears

Gears, especially in open gearing applications, share a set of well-known performance problems that crop up again and again across many different applications. The most common ones include excessive noise, vibration, heat, weight and corrosion. Gears also tend to be either over-lubricated or subject to wear, which respectively causes contamination from grease or metal particles.

  • Eliminate all lubrication 
  • Make your gear drives quiet 
  • Eliminate backlash
  • Learn to calculate plastic gears  to last the life of your application
