What is PEEK (Polyetheretherketone)?
PEEK is a high-strength, semi-crystalline thermoplastic polymer favored for its excellent thermal stability, chemical inertness, and mechanical durability. The chemical structure of PEEK consists of three benzene rings linked by ketone and ether groups. This structure, composed of a repeating sequence of benzene rings linked by ketone and ether groups, gives it a robust and stable semi-crystalline structure.
First synthesized in 1977 and commercially produced in 1981, this material is characterized by its ability to operate continuously at temperatures up to 250°C while maintaining excellent mechanical and electrical properties. Furthermore, it operates reliably in high-pressure water or steam environments up to 300°C. It also exhibits high mechanical strength and rigidity over a wide temperature range, as well as excellent creep resistance and abrasion resistance. Another key characteristic of PEEK is its natural flame retardancy, resulting in a very low risk of producing toxic gases.
Advantages of PEEK in Injection Molding

Professional PEEK Injection Molding Technology Delivers Consistent Quality and Performance
Our engineers design barrel dimensions based on the material of each PEEK polymer. This minimizes the residence time of the thermoplastic at its melt temperature, preventing material degradation and ensuring that every part we mold maintains the material’s optimal performance. Additionally, we have a specially designed control system for processing high-performance PEEK polymers. During molding, probes are placed in each mold cavity to monitor temperature and pressure to maintain optimal conditions, thus optimizing the quality and performance of every high-temperature polyetheretherketone (HT PEEK) component we produce. An additional feature of Elimold’s injection molding equipment is our injection compression technology. This technology allows us to compress or “imprint” parts while the mold is cooling.

Comparison of PEEK and PEI Injection Molding
In the field of injection molding, the core comparison between PEEK and PEI lies in their performance and cost. Both plastics possess similar properties such as high-temperature resistance and corrosion resistance. While their performance is similar, their costs differ significantly (typically, PEEK is 2-3 times more expensive than PEI). Although other plastics (such as PPS and LCP) may be comparable to PEEK and PEI in some aspects, they cannot replace PEEK and PEI in key indicators such as biocompatibility and long-term fatigue strength. Therefore, engineers must weigh performance and cost to select the optimal material.
FAQ
The typical tolerance for PEEK injection molding is ±0.05mm. Achieving precise tolerances depends on a variety of factors, including mold design, machine performance, and processing conditions. Proper mold maintenance and molding parameter control are crucial for consistently achieving the desired tolerances.
PEEK can be overmolded or used in multi-component injection molding, but this requires careful consideration of material and process conditions. Overmolding involves molding a PEEK part onto another material (such as metal or other plastics) to create a composite part with enhanced properties.
The recommended wall thickness for PEEK injection molded parts is typically 1.5mm to 5mm. While thinner wall thicknesses are possible, this requires careful mold design and precise process parameter control to ensure part quality and avoid defects such as warpage or incomplete filling.
We have professional mold designers and experienced technicians, and have introduced over 180 sets of advanced mold manufacturing equipment, with an annual mold production capacity of up to 1300 sets.
For products with low precision requirements, we can provide reverse engineering services based on the sample. However, if you can provide 2D or 3D drawings, it will help us understand your needs more accurately and provide you with a quote faster.
You need to provide 2D and 3D drawings so that we can provide a mold quote and start production faster. We support 2D drawing formats including AI, PDF, DWG, CAD, DXF, DLG, etc. We support 3D drawing formats including STP, STEP, etc.
Our factory strictly adheres to the precision requirements of the drawings you provide for installation and production. We will also communicate with you regarding the mold usage and precision requirements. If the mold does not meet your requirements and is due to a manufacturing problem on our part, our factory will be responsible for arranging rework. However, if the product is scrapped due to errors in your drawings, a separate solution will be required.
Depending on the application requirements, other alternatives can be considered, such as high-performance nylon, polyetherimide (PEI), and polyphenylene sulfide (PPS). However, these materials may not achieve the same superior performance as PEEK.
PEEK materials can maintain their mechanical properties at continuous temperatures up to 260°C. Compared to metals, they offer superior corrosion resistance and lighter weight while providing a similar strength-to-weight ratio.
