### Highlights Of PEEK Injection Molding

PEEK injection molding is a polyetheretherketone (PEEK) product manufactured using injection molding. It inherits all the advantages of PEEK resin while achieving complex structures and high dimensional accuracy through precision injection molding:

- Excellent Thermal Stability: Can operate continuously at 260°C, with short-term temperature resistance approaching 300°C, and can withstand repeated thermal shocks without deterioration.
- Superior Chemical Resistance: Stable to most industrial chemicals, including fuels, hydraulic fluids, acids, alkalis, and many solvents.
- Excellent Mechanical Strength and Toughness: Maintains rigidity and impact resistance at high temperatures, and is not easily deformed or broken.
- Excellent Sliding Properties: Low coefficient of friction and high wear resistance, particularly suitable for moving parts in unlubricated or harsh conditions.
- Stable Electrical Properties: Low dielectric constant with minimal influence from frequency and temperature, making it ideal for high-frequency and high-voltage insulation.
- Hygiene and Safety: Complies with FDA, USP Class VI, and RoHS requirements, suitable for medical and food contact applications.

### PEEK Injection Molding Process Techniques

Although PEEK has a high melting point and high melt viscosity, with proper process control, it can achieve high-precision molding of complex shapes:

- Raw Material Drying

- Before injection molding, it must be vacuum dried at above 150°C for at least 4 hours to ensure a moisture content below 0.02%.

- Temperature Setting

- Barrel: 360–400°C (slightly lower at the beginning, slightly higher at the end)
- Nozzle: 370–400°C
- Mold: 160–190°C, ensuring uniform crystallinity.

- Injection Strategy

- Use segmented injection: low-speed filling of the runner, high-speed mold filling to reduce shear stress and warpage.
- Maintain high holding pressure to ensure density.

- Mold and Design

- The mold must have a good heat conduction and venting system to avoid air entrapment and scorching.
- During design, ensure uniform wall thickness to reduce stress concentration.

- Post-processing Optimization

- Aging treatment at approximately 180°C can be performed to further release internal stress and improve dimensional stability and mechanical properties.

### Applications of PEEK Injection Molding

Due to its high designability and stable performance, PEEK injectin molding has found innovative applications in the following industries:

- Artificial Intelligence: Humanoid robot components
- Semiconductor Manufacturing: Wafer carriers, vacuum chamber components, electrostatic chuck insulation components
- Energy Equipment: Nuclear power plant components, high-temperature structural components for solar thermal power generation systems
- High-End Industrial Equipment: High-temperature guide components for textile machinery, heat-resistant components for printing presses
- Medical Implants: Spinal fixation systems, wound repair implants
- Precision Instruments: Core components for mass spectrometers and gas chromatographs
- Sporting Goods: Lightweight, high-temperature resistant parts for high-end bicycles and racing cars
