Processing Options
PEEK (Polyether Ether Ketone) can be processed using various methods depending on the application requirements. Here’s an overview of the primary processing options:
• Injection Molding
Process Overview: PEEK pellets are melted and injected into a mold cavity to produce complex shapes with high precision. It is the most common method for mass production of PEEK parts.
Advantages: Produces high-precision components with excellent surface finish and tight tolerances. Suitable for producing large volumes.
Applications: Automotive parts, medical components, and electronic housings.
• Extrusion
Process Overview: PEEK is melted and forced through a die to create continuous profiles like rods, sheets, and films.
Advantages: Ideal for producing semi-finished products like bars and tubes that can be further machined.
Applications: Pipes, insulation coatings, and sheets for further machining.
• Compression Molding
Process Overview: PEEK powder is placed into a heated mold and compressed under high pressure to form solid components.
Advantages: Suitable for producing thick-walled or large components that are difficult to produce using injection molding.
Applications: Structural components, heavy-duty industrial parts.
• 3D Printing (Additive Manufacturing)
Process Overview: PEEK is printed using Fused Filament Fabrication (FFF) or Selective Laser Sintering (SLS). In FFF, a filament is extruded layer by layer; in SLS, powdered PEEK is sintered with a laser.
Advantages: Enables the production of complex geometries and customized parts with reduced material waste.
Applications: Prototyping, customized medical implants, aerospace components.
• Machining
Process Overview: PEEK sheets, rods, or tubes produced via extrusion or compression molding are machined using CNC techniques to achieve high-precision parts.
Advantages: Allows for the creation of parts with extremely tight tolerances and complex designs.
Applications: Gears, bushings, medical devices.
