POM (Polyformaldehyde)

POM (full name: Polyformaldehyde) is an engineering plastic with no side chain, high density, high crystallinity, and linear polymer. It is known as “plastic steel” and has comprehensive and excellent properties, such as wear resistance, high hardness, and impregnation resistance. , Good rigidity (tensile elastic modulus), chemical stability, anti-segregation, and dimensional stability. POM is widely used in the automotive industry, electronic and electrical products, daily necessities, pipes and accessories, precision instruments, etc., and can replace metals such as bronze, zinc, and tin.
Automotive industry: POM is widely used in the automotive industry because the mechanical parts made of POM have the advantages of high mechanical strength, hardness, good wear resistance, low friction coefficient, easy maintenance, cost reduction, etc., and can be used in automobiles. Instead of the brass half-shank and planetary gears. It not only saves copper but also improves the service life.
Electrical and electronic industry: POM has the advantages of low power consumption, high dielectric strength, insulation resistance, and high arc resistance and is widely used in the electrical and electronic industry.
Agricultural Machinery: Hand sprayer parts, planter joints, transport parts, milking machine parts, irrigation housings, valves, joints, water bushings, etc.

How to Design Plastic Gears

Plastic gears are made of thermoplastic resin that changes shape when heated. This process, called injection molding, is commonly used to produce gears for various applications. Experts recommend that you consider the application for which you are designing the gear before beginning the design process. For example, if you’re making gears for a machine, make sure you know the torque and speed of the machine. Then, gears are designed according to these characteristics.
Then, the tooth flanks are designed to minimize the effects of molding stress and maximize load-carrying capacity. The tooth size of plastic gears is essential for load carrying capacity. However, smaller teeth are more prone to dental errors and may experience more stress. To avoid these problems, choose plastic gears with a slightly narrower face than steel gears. This will reduce the chance of mechanical interference. Finally, design gears with a diameter greater than 1.
Plastic gears have several advantages over metal gears. They are easy to process and have excellent strength and elasticity. Plastic gears can be made from unfilled nylon, acetal, or polyamide. Many of these come in standard shapes, including rectangles, squares, and circles. If you need a lot of plastic gears, it’s cheaper to make them by molding. These plastic gears are also an excellent choice for various applications.

Where are plastic gears’ applications?

While there are many uses for plastic gears, the automotive industry has seen the most significant growth in recent years. As amenities and competitive advantage become increasingly important to automakers, they attempt to integrate gears and motors into vehicle subsystems. These components range from liftgates and seats to electronic throttle bodies and turbo controls.
The first consideration in choosing a plastic gear material is its strength. The material must be rigid enough to withstand the expected loads and resist dimensional changes due to changes in environmental conditions. Vendors can provide helpful information about these properties. Additionally, we test the prototype gears under realistic conditions before working in production. In addition to plastic gears, other materials can be used for these applications.
The advantage of plastic gears is that they are inexpensive to manufacture. They are also easy to process and working in the short run. However, the disadvantage of plastic gears is that they have high dimensional tolerances. Fortunately, we design the plastic gears with a low coefficient of friction. Plastic gears can handle higher loads and speeds and are less likely to break or jam. The key is to choose an experienced and reliable manufacturer.
