Custom PEEK Machining Services – High-Precision PEEK Plastic Machined Parts
PEEK (Polyether ether ketone) is one of the most advanced engineering thermoplastics, offering outstanding mechanical strength, dimensional stability, and resistance to heat and chemicals. Our PEEK machining services are designed to meet demanding requirements for precision plastic components used in aerospace, medical, electronics, and industrial environments.
With extensive experience in PEEK plastic machining, we manufacture custom PEEK machined parts with tight tolerances and complex geometries, using CNC turning, milling, and drilling processes tailored specifically for this high-performance polymer.
Applications of PEEK Machined Parts
PEEK machined components are used across industries where durability, high temperature resistance, and chemical inertness are essential. Common applications include:
-
Medical & Life Sciences: surgical tools, implant-grade components, and dental devices
-
Aerospace & Defense: lightweight structural components, brackets, and insulators
-
Semiconductor Equipment: precision alignment parts, wafer handling trays
-
Automotive & EV: electrical insulators, bushings, bearing cages
-
Oil & Gas: valve seats, wear rings, and sealing components
-
Food & Beverage Processing: FDA-grade parts with thermal and chemical resistance
Due to its excellent properties, PEEK is often chosen over metal or other plastics when weight reduction and reliability are critical.
Understanding PEEK Plastic Machining
PEEK is a challenging material to machine and requires careful control of cutting parameters. Its machinability is lower than softer plastics due to its high strength and thermal properties, but with the right tooling and strategies, high-precision results can be achieved.
Key aspects of PEEK machining include:
-
Thermal management: Excessive heat during machining can cause softening or surface degradation. Using proper coolant and feed rates is critical.
-
Tool selection: Carbide or diamond-coated tools are often used for durability and precision.
-
Material stress: To avoid stress cracking or deformation, PEEK must be machined in controlled environments, especially for thin-walled parts.
-
Surface finish and tolerances: With optimized processes, finishes down to 0.4 Ra and tolerances within ±0.01 mm are achievable.
Machining Processes Based on Part Shape
The machining process is tailored based on the geometry and performance requirements of the part. Here’s how we determine the best approach:
-
Simple parts (e.g., rings, spacers, washers): CNC turning with precise diameter control
-
Flat or contoured parts (e.g., manifolds, brackets): CNC milling using multi-axis setups
-
Complex geometries (e.g., housings, channels, micro-features): 5-axis CNC machining for accuracy and repeatability
-
Tight-tolerance bores or threads: Precision boring and tapping with real-time inspection
Additionally, PEEK is available in reinforced grades (with glass or carbon fibers) and medical- or FDA-grade options. These variants influence the selection of tools and process parameters.
