PEEK (polyether ether ketone) is a thermoplastic material known for its high mechanical strength, heat resistance, impact resistance, flame retardancy, chemical resistance, rigidity, and long service life. It is widely used in industries such as automotive, aerospace, and medical devices. The manufacturing of thermoplastic resins typically employs traditional molding methods, including injection molding, extrusion molding, compression molding, and CNC machining.
Injection molding is suitable for high-volume, efficient production, enabling the rapid manufacturing of complex-shaped parts with consistent dimensions.
Melting: PEEK pellets are melted under high temperature.
Injection: The molten PEEK material is injected into a mold.
Cooling: The material inside the mold cools and solidifies into the desired shape.
Ejection: The solidified part is removed from the mold.
High production speed and efficiency
Excellent surface finish and dimensional accuracy
Ideal for mass production
Requires high-temperature, high-pressure equipment; mold costs are relatively high
The extrusion process is suitable for producing linear products such as pipes, rods, sheets, and films. Its main advantages include continuous production capability and high dimensional stability of the finished products.
Melting: PEEK material is heated and melted inside the extruder.
Extrusion: The molten material is forced through a die to form continuous profiles (e.g., tubes, rods, sheets).
Cooling & Hauling: The extruded profile is rapidly cooled and pulled to the desired length.
Annealing: Annealing at 160–200°C for 2–4 hours to relieve internal stresses.
Cutting: The cooled profile is cut to the required length as needed.
Capable of producing complex cross-sectional profiles (rods, sheets, pipes, custom shapes) with high design flexibility
Strong material orientation, resulting in superior mechanical properties
Simple and efficient process
Machining solid PEEK using traditional techniques such as turning, milling, drilling, and grinding.
Material Preparation: Use PEEK sheets, rods, or pre-formed blanks.
Fixture Setup: Secure the material on the CNC machine.
Programming & Machining: Program based on CAD/CAM data and perform machining operations like milling, turning, and drilling.
Inspection & Post-Processing: Check machining accuracy and surface quality, then conduct necessary post-processing (e.g., deburring, polishing).
Suitable for small batches, high-precision, or specially shaped parts.
Low material utilization, resulting in higher costs.
Requires controlled cutting speeds to prevent overheating and deformation of the material.
Suitable for manufacturing complex-shaped parts or small-batch production.
Mold Preheating: Preheat the mold to an appropriate temperature to improve molding efficiency.
Mold Filling: Evenly fill the preheated mold with PEEK material.
Heating & Pressing: Apply high temperature and pressure to melt the PEEK and ensure it fully fills the mold.
Cooling & Demolding: Gradually cool the mold, then demold the part after solidification.
Suitable for large, thick-walled, or low-stress parts.
Minimal material waste, resulting in lower costs.
Longer production cycle and lower precision compared to injection molding.
High flexibility in small-batch production.
