Plastic gears are used in automobiles, watches, sewing machines, structural control facilities and even missile accessories. Plastic gears are also used in many other fields, such as damping drives for ventilation and air conditioning systems (HVAC), valve drives in mobile facilities, automatic sweepers in common rooms, and power spirals for controlling surface stability on small aircraft. In the field of military equipment, screw gauges and control devices. Optional materials are POM, ABS, PA66, PVC, PEEK, etc.
PEEK gear is a high-performance plastic gear made of polyetheretherketone (PEEK) material. It has the characteristics of high temperature resistance, self-lubrication, high wear resistance, corrosion resistance and lightweight. Its long-term use temperature can reach 260°C, the friction coefficient is low, and no additional lubricant is required. It is suitable for high-load and high-frequency start-stop scenarios. PEEK gears are manufactured through injection molding process, with a precision of 7-9, high transmission efficiency and low noise. It is mainly used in aerospace, automobile, medical equipment and industrial robots, such as aircraft engine parts, automobile gearboxes, surgical instruments and robot joints, etc., to meet the needs of lightweight, corrosion resistance and efficient transmission, and become an important choice to replace traditional metal gears.

In the vast field of plastic parts processing, we focus on providing high-quality plastic gear customization processing services to global customers. We are committed to creating plastic gear products with excellent performance and precise matching for you through advanced processes and technologies.
● Material selection: We select high-quality plastic raw materials such as polyamide (PA), polyoxymethylene (POM), polycarbonate (PC), etc. to ensure the wear resistance, corrosion resistance and high strength of the gears.
● Precision control: Use advanced CNC processing equipment and precision measuring tools to ensure that the key dimensions of the gears, such as tooth shape, tooth pitch, tooth height, etc., are accurate and correct to meet the requirements of high-precision transmission.
● Heat treatment and surface treatment: According to customer needs, the gears are subjected to necessary heat treatment to enhance their mechanical properties, and surface treatment is performed to improve wear resistance and corrosion resistance.
● Quality control: Implement a strict quality control process from raw material inspection to finished product testing to ensure that each batch of gears meets industry standards and customer requirements.
● Lightweight: Compared with metal gears, plastic gears are lighter, which helps to reduce the overall weight of the equipment and improve operating efficiency.
● Low noise: Plastic gears generate less noise during operation, which helps to improve the working environment and enhance user experience.
● Corrosion resistance: Excellent corrosion resistance enables plastic gears to maintain long-term stable operation in harsh environments.
● Cost-effectiveness: The processing cost of plastic gears is relatively low, and they are easy to mass-produce, which helps to reduce overall costs.
● Automation equipment: Plastic gears are widely used in transmission systems in automation equipment, such as robots, automated production lines, etc., to achieve precise and efficient transmission control.
● Household appliances: In household appliances such as washing machines, blenders, and vacuum cleaners, plastic gears play a key transmission role to ensure the normal operation of the equipment.
● Auto parts: With the development of the lightweight trend, plastic gears are increasingly used in auto parts, such as steering systems, transmission systems, etc.
● Medical equipment: In medical equipment, plastic gears provide reliable transmission support for precision medical equipment with their low noise and corrosion resistance.
Material properties
● High temperature resistance: long-term use temperature can reach 260℃, short-term high temperature resistance of 300℃, suitable for extreme working conditions such as engines and high-temperature reactors.
● Self-lubrication: low friction coefficient (0.1-0.3), no need for additional lubricants, reduced maintenance costs, suitable for oil-free environments (such as food machinery).
● High wear resistance: the wear rate is only 1/4 of that of metal gears, and the tensile strength can reach 260MPa after carbon fiber reinforcement, which is suitable for high-frequency start-stop scenarios (such as robot joints).
● Corrosion resistance: except for concentrated sulfuric acid, it shows excellent resistance to chemical media such as organic solvents, weak acids and alkalis, and is suitable for chemical equipment.
● Lightweight: the density is only 1.3-1.4 g/cm³, which is about 1/5 of that of metal, significantly reducing the weight of the transmission system and improving fuel efficiency (such as automobile gearboxes).
Processing and performance
● Processing method: supports injection molding and precision processing, and can realize complex structural integrated design (such as integration of planetary reducer gears and bearing seats).
● Precision and efficiency: Gear precision can reach 7-9 levels, with high transmission efficiency and low noise (reduced by more than 15 dB compared to metal gears).
● Aerospace
Used in aircraft engine blades, landing gear, and seat adjustment mechanisms to meet lightweight and high temperature resistance requirements and help reduce fuel consumption.
● Automotive industry
Applied to engines, gearboxes, and electric power steering systems (EPS) to improve fuel economy and driving comfort. Typical cases include new energy vehicle drive motor gears.
● Medical equipment
Surgical robots, dental instruments, and imaging equipment meet biocompatibility and disinfection resistance requirements, such as PEEK joints replacing metal implants.
● Industrial robots
Joints and reducer core components to improve motion accuracy and operating efficiency. Tesla and Boston Dynamics have verified the maturity of its technology.
● Other fields
Chemical industry: Corrosion-resistant gears are used in reactors and pumps and valves; Electronics: Excellent insulation, used in semiconductor manufacturing equipment.
