The Main Application Fields of Peek Sheet Rod
The automotive and other (including aviation) transportation markets account for about 50% of PEEK resin consumption, semiconductor manufacturing equipment accounts for 20%, general mechanical parts such as compressor valves account for 20%, and medical equipment and analytical instruments account for 10% of the market.
Automobile and other transportation machinery
The market for PEEK resin is growing particularly rapidly in the automotive parts market, especially parts around the engine, gearbox parts, steering parts, etc. PEEK plastic is used to replace some traditional high-priced metals as manufacturing materials. As the automotive industry adapts to the requirements of miniaturization, lightweighting and cost reduction, the demand for PEEK resin will continue to grow. A European model has 44 parts that use PEEK plastic instead of traditional metal products.
IT manufacturing field
Semiconductor manufacturing and the electrical and electronic industry are expected to become another growth point for the application of PEEK resin. In the semiconductor industry, in order to achieve high functionality and low cost, larger silicon wafers and more advanced manufacturing technology are required. Low dust, low gas emission, low ion dissolution, and low water absorption are special requirements of semiconductor processes for various equipment materials, which will be where PEEK resin will show its strengths.
Office machinery parts
For the separation claws, special heat-resistant bearings, chains, gears, etc. of copiers, when PEEK resin is used instead of metal as its material, the parts can be lightweight, fatigue-resistant, and oil-free lubrication can be achieved.
Wire coating field
PEEK coating has good flame retardancy and does not require the addition of any flame retardant. Its flame retardancy level can reach UL94 V-0. PEEK resin also has the advantages of anti-peeling and radiation resistance (109rad), so it is used in special wires in military, nuclear energy and other related fields.
Plates, rods and other fields
In the application of PEEK in some special fields, it is often encountered that there are many varieties of small quantities. At this time, it is very beneficial to use rods, plates and other profiles for mechanical processing and manufacturing.
Fiber field
PEEK fiber (including monofilament) industrial filter cloth, industrial brush and other products. In the field of composite materials, the charm of PEEK fiber lies in its thermoplasticity and high temperature resistance. In addition to heat resistance, the appeal of industrial filter cloth and industrial brushes also lies in their chemical resistance and wear resistance.
Medical analysis equipment field
Because PEEK can withstand repeated high-pressure sterilization, it can be used to manufacture endoscope parts and dental descaling devices in medical devices. In addition, due to its high strength and low solubility, PEEK has been used in liquid chromatography columns, tubes, accessories, etc. for instrument analysis. Moreover, due to its good compatibility with the human body, PEEK has successfully replaced traditional titanium metal as an artificial bone material.
4 Processing Methods for Peek
Compression Molding
- In compression molding, the plastic material is preheated and placed into the mold cavity. The mold is closed under pressure and heated. After the part cools, it is removed from the mold and flash is removed. This process works very well for reinforced polymers and is the standard manufacturing method for making PEEK parts.
- Compression molding produces parts with a good surface finish. Setup times are very fast and setup costs are relatively low. However, it cannot handle geometries with undercuts, and the processing time and part consistency are not as good as injection molding.
Injection Molding
- Injection molding is one of the most common processing methods for producing plastic parts, including PEEK. In injection molding, molten plastic is injected (i.e. forced) into a mold at high pressure. After cooling and solidification, the part (or parts) are removed from the mold. Minimal post-processing is required, usually in the form of trimming flash and excess plastic.
- Injection molding is suitable for thin-walled parts and can produce complex parts with fine details. Injection molding produces parts with good surface finish and high dimensional accuracy. From a production perspective, its advantages include high productivity and low labor costs. Disadvantages are high tooling requirements, long lead times, and high costs.
Extrusion
- Extrusion is used to make polymer parts with constant cross-sections, including tubing. It is another common manufacturing process for PEEK parts. The heated plastic is passed through an open mold under high pressure.
- Production costs tend to be low, setup times are fast, and initial costs are relatively low. However, precision is not as high as injection molding, and it is only suitable for parts with uniform cross-sections.
Centrifugal Molding
- In centrifugal casting (sometimes called rotational molding, centrifugal molding, or rotomolding), molten polymer material (such as PEEK) is placed in a mold and sealed. The mold and polymer are heated until the polymer is liquid. The mold is then rotated on multiple axes. Centrifugal forces evenly distribute the polymer over the mold's inner surfaces. This manufacturing method can be used to make complex hollow parts with thin walls and very low residual stresses. It is well suited to reinforced materials.
- Centrifugal molding provides an excellent surface finish with limited tooling costs. It is well suited for both short and long runs. Its main disadvantages are a lack of precision and low production speeds compared to injection molding.

Peek rod is a kind of semi-finished profile extruded with PEEK raw material, which has the characteristics of high temperature resistance, high wear resistance, high tensile strength and good flame retardancy. Peek rod can be used to process various specifications of PEEK parts, and can be used to manufacture mechanical parts with high requirements, such as gears, bearings, valve seats, sealing rings, pump wear rings, gaskets, etc. The parts processed with PEEK rods are widely used in key connectors in aerospace, medical, semiconductor, pharmaceutical and food processing industries.
The density of pure peek rod is about 1.35, and that of modified peek rod is about 1.42. However, it should be noted that the outer diameter of PEEK rod is generally larger than the calibrated one, so the weight of single peek rod should be based on the actual outer diameter. For example, the control sizes of 10 mm peek rods from different manufacturers are different, some of which are 10.5, 10.8 or even 11, resulting in different weights.
