Frequently Asked Questions
What plastic materials do you use for gears?
Common materials include POM (Delrin), PEEK, Nylon (PA66), PTFE, UHMW-PE and PC/ABS. Material selection depends on load, speed, temperature and chemical environment.
Can you produce plastic gears by injection molding?
Yes. For high-volume programs, we can support injection molding. For prototypes and low volumes, we machine from bar stock.
Are plastic gears suitable for high-speed applications?
Plastic gears are suitable for moderate-speed, low-to-medium load applications. For high-speed or high-load applications, metal gears are recommended.
Can you produce glass-fiber reinforced plastic gears?
Yes. Glass-fiber reinforced nylon and PEEK can be used for higher strength and stiffness. Specify the reinforcement requirement on your drawing.
