Why choose MingLi?

Instead of the materials mentioned about, MingLi provide special material, PEEK(Polyetheretherketone).

PEEK (Polyetheretherketone) is a special material for plastic gears due to its exceptional properties and performance characteristics. PEEK is a high-performance thermoplastic that offers several advantages for gear applications. Here are some key reasons why PEEK is considered special:

1. High Temperature Resistance: PEEK can withstand high temperatures up to 250°C (482°F) without significant loss of mechanical properties. This makes it suitable for applications where gears need to operate in elevated temperature environments.
2. Excellent Mechanical Properties: PEEK exhibits excellent mechanical properties, including high strength, stiffness, and fatigue resistance. It has a high tensile strength and modulus, allowing it to handle heavy loads and high stresses.
3. Wear Resistance: PEEK has excellent wear resistance, making it suitable for gears subjected to high friction and abrasive conditions. It can withstand repetitive sliding or rolling motion without significant wear or degradation.
4. Chemical Resistance: PEEK is highly resistant to chemicals, solvents, and many harsh substances, making it suitable for applications where gears come into contact with aggressive fluids or environments.
5. Low Friction and Self-Lubricating: PEEK has low friction characteristics, which reduce the need for additional lubrication in some applications. It exhibits self-lubricating properties, allowing it to operate smoothly and efficiently without the need for external lubricants.
6. Dimensional Stability: PEEK has excellent dimensional stability, meaning it maintains its shape and dimensions even under fluctuating temperature and humidity conditions. This ensures consistent and accurate gear performance over time.
7. Electrical Insulation Properties: PEEK is an excellent electrical insulator, making it suitable for gear applications that require electrical isolation or where electrical components are in close proximity to the gears.
8. Biocompatibility: PEEK is biocompatible and widely used in medical and healthcare applications, such as implantable devices and surgical instruments. This property allows for the utilization of PEEK gears in medical gear systems.
