The plastic double spur gear is a type of plastic gear which has two spur gears piled together. Generally speaking, they have different dimensions of diameters.

The most common plastic gears are spur gears, cylindrical worm gears, and helical gears. Almost all gears made of metal can be made of plastic.
Compared with plastic gears of the same size, metal gears work well and have good dimensional stability when temperature and humidity change. But compared with metal materials, plastic has many advantages in terms of cost, design, processing, and performance.
Compared to metal molding, the inherent design freedom of plastic molding ensures more efficient gear manufacturing. Products such as internal gears, gear sets, and worm gears can be molded from plastic, which is difficult to develop from metal materials at a reasonable price. Plastic gears have a wider application area than metal gears, so they push the gears towards higher loads and more power. The plastic gear is also an important material that meets low-quiet operation requirements, which require high precision, a new tooth profile, and materials with excellent lubricity or flexibility.
Plastic gears are lighter and more inert than metal gears. They can be used in environments where metal gears are easily corrupted and degraded, such as water meters and chemical equipment control. Gears made of plastic generally do not require secondary processing, so compared to stamped and machined metal gears, a cost reduction of 50% to 90% is guaranteed.
