What type of plastic is used for gears?
Plastic materials for gears Most plastic gears are made from nylon and acetal. But nylon absorbs moisture with resultant changes in properties and dimensions. Acetal copolymers provide long-term dimensional stability as well as high fatigue and chemical resistance over a wide temperature range.
How are small plastic gears made?
Plastic gears are manufactured with the same machining process as are metal gears, usually milling or hobbing. The very low cutting forces permit high infeed rates. This reduces manufacturing cost. Milling with high rates of infeed may produce a wavy, rough surface which may seem detrimental to long-term performance.
Can polyethylene plastic be repaired?
One of the universal truths about polyethylene is that it is difficult to repair. Fortunately, it is a material that rarely needs repair, but there will be times. Shallow scratches and gouges are sometimes best lived with. Unless quite deep, they are cosmetic in nature and will not impact the integrity of the hull.

Why is nylon used for gears?
Many times, nylon is used as a gear material in order to reduce the noise of a metal gear train or to reduce vibration. Nylon gears can also be introduced as a failsafe in a complex drivetrain.
What are POM gears?
Generally, POM, PA, and PC are used as materials for injection molded plastic gears, among which POM is most abundantly used [1]. For POM gear, their use for high tooth root stress is limited to ca. 40 MPa at 80 °C and working temperature of POM is limited due to its low melting temperature (ca. 160 °C).
Step 1: Materials Needed to Fix Broken Gear
you need a plastic steel epoxy, Popsicle stick, any mixing medium for your epoxy mixture and brush and detergent soap or dish washing liquid.
Step 2: Cleaning
Be sure that your gear is free from oil and dust. use dish washing or powdered soap and brush to clean the gear
Step 4: Curing
wait for an hour to harden the epoxy, since the epoxy is not hard enough and the epoxy is flowing slowly, you need to monitor the flowing or moving of the epoxy not to stuck in one area of the gear
Step 5: Moulding the Teeth
After an hour the resin will going to be hard, just like a clay, position the new mold gear in its gear partner, then rotate slowly to adapt the teeth of the other gear by the way you need to put some grease on the other gear so that the epoxy will not stick to the other gear. rotate it slowly till the rotation will fit to each gear.
Step 6: Total Curing
remove the gear to the gear box assembly and cure it on a well ventilated area for a day
Step 7: Cured Epoxy Gear
Install the hardened gear in the gear box, assemble the parts. this gear part belongs to my meat grinder.
