PEEK Profiles

You are here: Home / PEEK Profiles

PEEK (polyetheretherketone) is polyetheretherketone (PEEK for short), which is a linear aromatic polymer compound containing chains in the main chain of the molecule. Its structural unit is oxygen-p-phenylene-oxy-carbonyl-p-phenylene, which is semi-crystalline and thermoplastic. Processed into PEEK plate, PEEK rod, PEEK tube, PEEK ring, PEEK sheet, PEEK filament, PEEK film, etc. by powder, particle molding, extrusion process.

What Is PEEK Extrusion Profiles

What Is PEEK Profiles

Peek Extrusion Profiles is the process of transforming peek alloy into cross-sectional profiles. The end-results have a wide range of uses, and can be easily machined and yet offer strength and stability. While you do get custom peek extrusion shapes, there are three main types of peek extrusion profiles, each serving its own purpose for unique projects.

These profiles include hollow, semi-hollow, and solid extrusion profiles.

  • Solid peek extrusions have no voids or openings. These solid structures have a wide variety of uses, including creating compact, cross-sectional structures, structures with or without protrusions, curved shapes, wrap-around shapes, and more! This process is usually lower-priced due to the fact that it’s easier and faster to extrude.
  • Semi-hollow peek extrusions are only partially enclosed. A semi-hollow extrusion usually includes shapes that are circular or rectangular but require a gap on one side. This can become confusing as a solid shape can also include a partially enclosed void. The difference lies in the size of the respective gap.
  • Hollow Peek extrusions are shapes that are completely hollow anywhere in the cross-section. This means that the void or opening can include a specific shape, be molded into a variety of different shapes, or include more than one void extruded into a specific profile.

The Application Of PEEK Profiles

Peek profiles are widely used in aerospace, automobile manufacturing, electrical and electronic, medical and food processing, petroleum machinery pipelines and other fields.

PEEK special engineering plastics mainly include PEEK-450G (pure resin), PEEK450GL30 (containing 30% glass fiber), PEEK450CA30 (containing 30% carbon fiber), PEEK450FC30 [containing 30% (carbon fiber + graphite + PTFE) these four grades . The profile has outstanding characteristics and advantages such as high temperature resistance, wear resistance, hydrolysis resistance, chemical corrosion resistance, high strength and self-lubrication. Therefore, the profile also has good machinability, can be milled, turned, ground, carved and ultrasonic welded, with rigidity and toughness. The processing requirements can be met by using common machining equipment, but special engineering plastics differ from metal materials and general engineering plastics in terms of thermal expansion, heat dissipation, elasticity, etc. The following precautions are proposed for users’ reference when machining.

  1. According to the materials of different grades, the processing tools are selected. Generally, alloy knives can be used, tungsten steel knives can be selected, and diamond knives are better. The hardness of the white steel knife is too low, it is easy to wear, and it is not usable;
  2. Use coolant when necessary to reduce wear and heat conduction; this picture is machining
    During the process, the high temperature caused by the friction between the end face of the tool and the product leads to the melting of the material.
  3. It is good to increase the speed of the lathe to improve the machining effect by setting the feed amount to a small value;
  4. The material of PEEK450CA30 is particularly easy to damage the knife, and the size is relatively easy to change, so it is necessary to sharpen the knife or change the knife frequently. Therefore, in the process of processing, it is necessary to ensure that the turning tool must be sharp. After the blade is worn, the turning surface will heat up, causing the surface of the product to be rough or poor in size.
  5. This material has good toughness, and the scrap is not easy to break. It is necessary to clean up the scrap in time to avoid the entanglement of the scrap resulting in poor products.
