PEEK parts customization

With deep expertise in materials and processing capabilities, Junhua provides PEEK-based mechanical component solutions - bushings, gears, sealing rings, sliders, valve plates, etc., helping equipment significantly improve wear resistance, reduce lubrication dependency and extend service life.

Core Material

PEEK (recommended) - High wear resistance, high temperature resistance, chemical resistance, suitable for critical load-bearing and sliding parts.

Typical Benefits

Reduce maintenance downtime, extend component life, lower lubrication costs, weight reduction and improved reliability.

Delivery Capability

From material selection → molds → injection molding/extrusion/machining → mass production, supporting rapid prototyping.

Industry Pain Points

  • Severe friction and wear, short part life leading to frequent replacement.
  • High dependence on lubrication, high maintenance costs and downtime.
  • Complex media (oil/water/acid-base) causing corrosion and performance degradation.
  • High requirements for assembly and tolerances, requiring long-term dimensional stability.

Targeted Solutions

What is PEEK?

PEEK and its modified composite materials show excellent performance under high temperature and high humidity conditions. PEEK have excellent chemical corrosion resistance, self-lubricating, and wear-resistant properties, so it has become the most ideal material to replace copper alloys and ordinary rubber. Compared with them, PEEK has longer service life which can reduce equipment operating costs, improve equipment operating reliability.

what is peek

High Temperature Performance

PEEK's performance can remain stable in the temperature range from -196°C to 260°C. Under extreme working conditions, it can withstand 300"C for a short time. The performance of PEEK is still reliable even in high temperatures of several kilometers underground work environment.

High Strength and Wear Resistance

Compared with other plastics, PEEK is resistant to compression, impact and also have good fatigue resistance. PEEK is durable in mechanical equipment and wear-resistant environments.

Double the Service Life

PEEK sealing solutions can improve the part service life. Some domestic chemical companies use the PEEK5600FE20 polytetrafluoroethylene modified material designed by JUNHUA PEEK to replace the original material, the service life of the wear parts can even be extended by 1.3-3 times.

Corrosion Resistance

PEEK is chemically inert, and has no reaction to most acids, oils, greases and all other organic and inorganic solvents or enzymes, and can still maintain good strength and dimensional stability.

Self-lubricating

PEEK has low friction coefficient, low running resistance, can be used without oil in some working conditions. The equipment is cleaner, thus improving process reliability, improving energy efficiency and saving costs.

More dom in Design

Injection molds can be used for rapid injection molding of large quantities of complex special-shaped parts, and the cost is low compared to machining.

Common PEEK Grades and Properties

PEEK is a high-temperature thermoplastic with a high glass transition temperature (143°C) and melting point (343°C), and a heat deflection temperature under load of up to 316°C (for grades reinforced with 30% glass or carbon fiber).

1. PEEK5600G (brown-gray/khaki) is made from pure polyetheretherketone resin and offers the best toughness and impact resistance of all PEEK grades. Pure PEEK can be sterilized using convenient methods (steam, dry heat, ethanol, and gamma-rays), and the raw materials used in its manufacture comply with EU and US FDA food compatibility regulations. These characteristics make it widely used in the medical, pharmaceutical, and food processing industries.

2. PEEK5600LF30 (black) The addition of PTFE, graphite, and carbon fiber makes PEEK5600LF30 a bearing-grade plastic. Its superior tribological properties (low coefficient of friction, wear resistance, and high peak pressure limit) make it an ideal material for this class of friction applications.

3. PEEK5600GF30 (Brown-Gray): This material is a reinforced grade of plastic filled with 30% glass fiber. It offers superior rigidity, creep resistance, and dimensional stability compared to PEEK, making it ideal for structural parts. It can withstand fixed loads for extended periods at high temperatures. If PEEK5600GF30 is used as a sliding component, its suitability should be carefully verified, as the glass fiber can scratch mating surfaces.

4. PEEK5600CF30 (Black): This material is reinforced with 30% carbon fiber. It offers superior mechanical properties (higher elastic modulus, mechanical strength, and creep resistance) and wear resistance compared to PEEK5600GF30. Furthermore, carbon fiber-reinforced plastic has 3.5 times the thermal conductivity of unreinforced PEEK, dissipating heat more quickly from the bearing surface.
