PEEK Mouldings

_______________________________________________________________________________________________________________________________________________________________________

PEEK mouldings are advanced plastic components manufactured using injection moulding or precision machining of polyetheretherketone (PEEK), a high-performance thermoplastic known for its outstanding combination of mechanical strength, chemical inertness, and thermal stability. These moulded parts are widely used across demanding industries such as aerospace, automotive, medical, electronics, and chemical processing due to their ability to withstand harsh environments and maintain dimensional accuracy.

PEEK mouldings offer excellent tensile strength, stiffness, and wear resistance, making them ideal replacements for metals and ceramics in applications requiring lightweight yet durable parts. Their high continuous service temperature of up to 260°C (500°F) allows them to perform reliably in high-heat environments without losing mechanical integrity or shape.

The chemical resistance of PEEK ensures long-term durability against acids, bases, solvents, and hydrolysis, which is critical in medical implants, fuel system components, and chemical processing equipment. Additionally, PEEK’s low friction coefficient and excellent fatigue resistance enhance the lifespan of moving parts such as gears, bearings, and valve components.

Key Benefits

Superior Mechanical Properties: High strength, toughness, and stiffness for demanding structural applications.

Thermal Stability: Maintains performance under continuous high temperatures and thermal cycling.

Chemical Inertness: Resistant to a broad spectrum of aggressive chemicals and solvents.

Lightweight: Reduces overall system weight, improving efficiency and energy consumption.

Precision Moulding: Supports complex geometries and tight tolerances for custom and high-volume production.

Biocompatibility: Suitable for medical devices and sterilizable components.

Applications span aerospace fuel and hydraulic systems, automotive engine and transmission parts, medical surgical instruments and implants, electronic housings and connectors, and industrial seals and gaskets.

By choosing PEEK mouldings, manufacturers benefit from a high-performance polymer solution that delivers long service life, reduced maintenance, and enhanced reliability in the most challenging environments, helping to replace heavier, less durable traditional materials.
