We specialize in high-performance engineered plastic parts that enable superior component reliability and performance in the aerospace, medical, automotive, and semiconductor industries.
Are you struggling with delivery delays or critical dimensional errors? Our PEEK CNC machining services ensure on-time delivery of high-precision parts with tolerances as close as ±0.005 mm to solve the manufacturing challenges you face in your application.
PEEK CNC machining is a high-precision subtractive manufacturing process that produces complex, close-tolerance parts from PEEK. PEEK is a high-performance thermoplastic that is highly regarded for its mechanical strength, chemical resistance, and thermal stability. The process uses computer-controlled CNC machines (such as 3-, 4-, or 5-axis systems) to cut, drill, mill, and shape solid PEEK material into dimensionally accurate finished parts.
The process is commonly used in industries such as aerospace, medical, semiconductor, and automotive. The parts are used in applications where high temperatures, frequent sterilization, corrosive chemicals, or continuous mechanical stress are not compromised.
PEEK is renowned for its exceptional strength, stiffness, and durability. Below is a summary of its key mechanical properties:
| Property | Typical Value | Unit | Test Standard |
|---|---|---|---|
| Tensile Strength | 90–100 | MPa | ISO 527 / ASTM D638 |
| Tensile Modulus | 3,600–4,000 | MPa | ISO 527 / ASTM D638 |
| Elongation at Break | 20–30 | % | ISO 527 / ASTM D638 |
| Flexural Strength | 140–160 | MPa | ISO 178 / ASTM D790 |
| Flexural Modulus | 4,000–4,300 | MPa | ISO 178 / ASTM D790 |
| Compressive Strength | 120–150 | MPa | ASTM D695 |
| Impact Strength (Notched Izod) | 3.5–4.0 | kJ/m² | ISO 180 / ASTM D256 |
| Hardness (Rockwell) | R126–R130 | — | ASTM D785 |
| Density | 1.30–1.32 | g/cm³ | ISO 1183 / ASTM D792 |
We deliver reliable, high-precision PEEK machining solutions that meet the strict demands of aerospace, medical, automotive, and semiconductor industries.
With 5 years of CNC machining experience, we can achieve the tightest tolerances with our advanced PEEK CNC machining capabilities. We always maintain a tolerance of ±0.01 mm, thus avoiding assembly failures and ensuring that your critical components fit and function perfectly. Our strong quality management system certified by ISO 9001 and IATF 16949 provides a solid foundation for every process.
While PEEK is a high-performance thermoplastic known for its excellent natural surface quality, various post-processing treatments can further enhance its functionality, aesthetics, and suitability for specialized applications. Below is a table outlining the common surface treatment options available for PEEK machined components:
| Surface Treatment | Description | Benefits | Appearance | Typical Applications |
|---|---|---|---|---|
| Polishing | Mechanical process to smooth and refine the PEEK surface. | Improves shine, reduces friction, and enhances cosmetic appeal. | Smooth, semi-gloss to glossy | Medical instruments, high-precision components, display parts |
| Bead Blasting | Fine glass beads are blasted to create a uniform surface texture. | Removes machining marks, creates a matte finish, and improves grip. | Matte, textured | Industrial housings, hand-held tools, non-reflective parts |
| Machined Finish | Surface straight from precision CNC machining, often sufficient for PEEK. | Maintains tight tolerances and surface flatness with minimal processing. | Natural, slightly matte | Structural parts, aerospace brackets, automotive bushings |
| Laser Marking | High-precision laser used to engrave or mark part surfaces. | Enables permanent part identification without damaging mechanical integrity. | Crisp, high-contrast marks | Medical parts, traceable components, branding or labels |
| Custom Coatings | Specialized coatings (e.g., PTFE-based) applied for specific performance needs. | Enhances wear resistance, reduces friction, or adds chemical shielding. | Coated, varies by formula | Bearings, pump parts, sealing surfaces, sliding components |
Note: Unlike metals, PEEK cannot be anodized or powder coated. Instead, surface finishing focuses on enhancing its inherent polymer characteristics for specific functional or cosmetic purposes.
At VMT, we specialize in CNC machining PEEK for high-precision applications, but our capabilities go beyond that. We also offer advanced 3D printing for rapid prototyping and complex part geometries, as well as extrusion services to produce high-quality PEEK rods, tubes, and sheets.
Laser cutting uses focused laser beams to precisely cut thin PEEK sheets. It allows for clean edges, tight detail, and minimal mechanical stress, making it suitable for creating gaskets, seals, and electronic insulation parts.
PEEK extrusion involves melting the material and pushing it through a die to create continuous shapes like rods, tubes, and profiles. It’s suitable for manufacturing stock shapes or semi-finished products used in further machining or cutting.
Using specialized high-temperature printers, PEEK filament is melted and deposited layer-by-layer. 3D printing enables rapid prototyping and the production of complex geometries with minimal material waste and shorter lead times.
