When generally there is a huge temperature fluctuation in the Plastic Gear Rack application form environment, when the diameter is large or when presently there is load upon its keyway, metal hub made of S45C or stainless may sometimes be used. In these cases, one’s teeth portion and the hub part are attached as well as screws. If it’s extremely hard to screw with each other, two parts are fused jointly and converted to fused gears. Ever-Power’s fused gears are designed so that the holding strength of the fused surface is stronger than the tooth strength.
The positive characteristics of plastic gears include being lightweight, non-rusting, peaceful, injection molding enabling low priced and huge production, and able to operate without lubrication by mating with metal gears. On the other hand, low strength, tendency to carry heat, large dimensional modify including backlash in comparison to metal, etc. are a number of the points requiring caution. The degree of dimensional adjustments that happen with plastic gears rely on the capability to resist temperature alter, moisture absorption price and resistance to chemical substances.
So far as the applications of plastic-type gears, they are found in varying industries such as 
food production machines, gadgets, chemical, toy, and medical devices industries.
Our engineering department might help in customizing gears to your drawings and specifications.
