How we deliver ‘under the hood.’

When you partner with us, you benefit from our full range of in-house processes and resident knowledge that accompanies your project from start to finish across our global network.

Reliable performance & quality

Decades of experience in optimizing mechanical performance, mesh analysis, and material selection, including backlash, pressure angle, sideroll ratio, root clearance, and contact ratio to account for stress and fatigue performance and thermal and humidity expansion.

Smooth actuation & low vibration

Deep expertise in gear design, DFM, material selection, and plastic gear manufacturing further supported by in-house coating expertise

Low noise & optimized weight

Highly skilled in a range of polymers (including glass-filled polymers) in addition to full DFX services

Speed to market

Comprehensive design to rapid prototype to initial production using the turnkey Q-drive or similar platforms

Cost effective

Streamlined end-to-end approach, beginning with a focus on design for cost (multiple processes in one, material choice & more)

Consolidated, stable supply

Vertical integration with advanced plastic injection molding technology further supported by complementary processes including extruded tubing, assembly, and motors, as well as a global manufacturing presence with facilities in the U.S., China, and Mexico

What our customers are saying
One particular capability where they really stand above competitors is project management. This is done in a professional way, and we have quite high complexity involved. They are doing an outstanding job.
Global Commodity Manager / Multi-national Medical Device Company
They’ve been a good partner – good communication and meeting our needs…Open and honest. Good partnership.
Business Unit General Manager / Global Medical Device Company
The Aptyx team did an excellent job converting brass gears to plastic. Because of the design challenges, deep expertise in gears and over-molding was crucial. They also converted an expensive, labor-intensive part with quality issues to two-shot molding, which dramatically reduced cost, improved quality, and easily met the production needs. Apytx came through for us because of very good program management and good technical expertise.
Lead Principal Engineer / Global Medical Device Company
Working with your team has been one of the best contract manufacturing interactions ever. They made the whole thing happen even when it was chaos on our end.
Director of Regulatory Affairs/Product Development Manager / Medical Device Startup
The team at Aptyx is a pleasure to work with. They understand & act like true partners. I routinely hold them up as the model of the type of supplier that we need.
