PEEK gears (liquid transport)

PEEK gears used in liquid delivery systems

The main trends in the industry are: improving performance and efficiency, reducing weight and miniaturization while reducing costs. In gear applications, engineers are looking for new materials to replace existing metal materials, or to improve typical polymer material solutions to meet the high requirements of future systems for high performance. Because different types of loads are always sent at the same time, gears need to meet multiple complex needs. The normal operation of gears depends on good friction and mechanical properties, resistance to corrosive media, durability and heat resistance, and dimensional accuracy.

Polyetheretherketone (PEEK) is a new type of high-performance special engineering plastic that has a production and use history of more than 30 years.

PEEK gear characteristics and advantages

◆ High temperature resistance – the long-term use temperature certified by UL in the United States is 260°C. Even when the temperature reaches 300°C, it can still maintain good mechanical properties.

◆ Wear resistance – In many extremely harsh application environments such as high temperature, high load, and strong corrosion, PEEK polymers and their composite materials have good wear resistance.

◆ Self-lubricating – It has a low friction coefficient, can achieve oil-free lubrication, and can work for a long time in media such as oil, water, steam, weak acid and alkali.

◆ Corrosion resistance – insoluble in common solvents, and has good corrosion resistance to various organic and inorganic chemical reagents.

◆ High strength : It has good mechanical strength among plastics. It also has high rigidity and surface hardness.

◆ Easy to process – parts can be directly processed by injection molding process. Post-processing such as turning, milling, drilling, tapping, bonding and ultrasonic welding can be performed.

◆ Long life

◆ Low energy consumption

◆ Lightweight

◆ Low noise

Service scope:

In recent years, Junhua PEEK’ PEEK high-performance polymer materials have been successfully used as an alternative material in a wide range of industries. In response to the continued development of this trend, Jiangsu Junhua has sufficient resources to help customers in gear design, sample processing, mold opening and injection molding, mass production and application development. The existing processing technologies include gear hobbing, direct injection molding, gear shaping and other processes.

Junhua PEEK was established in 2007. Relying on the previous 16 years of experience in PEEK R&D and production, it has become a joint-stock company with a full industrial chain that integrates the R&D, production and sales of PEEK resin raw material polymerization, PEEK sheet, rod, tube and other profile continuous extrusion molding, and finished parts. It has production and sales subsidiaries in many cities in China, and its products are sold to foreign and domestic markets such as Europe, America, and Southeast Asia.

The main trends in the industry are: improving performance and efficiency, reducing weight and achieving miniaturization while reducing costs. PEEK gear applications require finding new materials to replace existing metal materials or to improve typical polymer material solutions to meet the high performance requirements of future systems.

PEEK gears are widely used due to their advantages such as light weight, wear resistance, self-lubrication, low noise, corrosion resistance and high temperature resistance.

Junhua PEEK can provide customers with the determination and selection of gear raw materials, surveying and mapping, gear design, mold opening and injection molding, sample processing, and even mass production. It also provides application scenarios, working conditions and PEEK gear solutions.
