Advantages of POM plastic raw materials for making gears

Metal gears perform well and have good dimensional stability with changes in temperature and humidity compared to plastic gears of the same size. But plastics have many advantages over metal materials in cost, design, processing and performance.

 The inherent design freedom of POM plastic molding ensures more efficient gear manufacturing compared to metal molding. Products such as internal gears, gear sets, worm gears, etc. can be molded from plastics, which are difficult to mold using metal materials at a reasonable price. Plastic gears are used in a wider range of applications than metal gears, so they drive the development of gears that can withstand higher loads and transmit more power. Plastic gears are also an important material that meets low-quiet operation requirements, which requires the emergence of high-precision, new tooth shapes and materials with excellent lubricity or flexibility.

Gears made of POM plastic generally do not require secondary processing, so compared to stamped parts and machined metal gears, the cost is reduced by 50% to 90%. POM plastic gears are lighter and more inert than metal gears, and can be used in environments where metal gears are prone to corrosion and degradation, such as the control of water meters and chemical equipment.

 Compared with metal gears, POM plastic gears can deflect and deform to absorb the effects of impact loads, and can better disperse local load changes caused by shaft deflection and misaligned teeth. The inherent lubricating characteristics of many plastics make them ideal gear materials for printers, toys and other low-load operating mechanisms, lubricants not included here. In addition to operating in a dry environment, gears can also be lubricated with grease or oil.
