Thanks to its five core advantages—exceptional dimensional stability, high-temperature resistance, cleanliness and low dust generation, electrical insulation and antistatic properties, and wear resistance and self-lubrication—PEEK is rapidly replacing traditional materials such as metal, epoxy boards, and bakelite in precision tooling and fixtures, becoming the material of choice for high-precision and high-tech manufacturing processes in the semiconductor, electronics, and precision manufacturing industries.
Robotic Automation Gripper Fixtures
Gripper pads, positioning grippers for collaborative robots, and core components for six-axis robotic arm loading/unloading grippers: used for gripping glass, lithium-ion battery electrodes, smartphone mid-frames, camera lenses, and more; soft texture and burr-free, preventing crushing or scratching of high-gloss workpieces; self-lubricating dry gripping eliminates the need for lubricating grease, preventing oil contamination of battery cells and precision electronic components; Anti-static modified PEEK eliminates the risk of electrostatic discharge damaging semiconductor components during handling.
Internal Guide Bushings for Grippers
Designed to withstand millions of high-frequency opening and closing cycles, these wear-resistant bushings replace copper bushings, require no maintenance, reduce weight by 55%, and lower the gripper’s no-load power consumption.
Semiconductor & Wafer Precision Fixtures
Wafer clamps and wafer tweezers are used to hold wafers during cutting, polishing, and coating processes; they remain distortion-free even after prolonged exposure to high temperatures of 250°C. With low outgassing and low outgassing rates, they prevent dust and impurities from contaminating wafers in cleanroom environments. Anti-static models prevent electrostatic discharge from damaging chip circuits.
PEEK Wafer Holder
Ultra-high purity and dust-free, preventing wafer contamination; resistant to immersion in cleaning solutions without degradation. High-temperature resistant, suitable for high-temperature manufacturing processes. Extremely high volume resistivity, isolating the wafer from the metal chamber of the equipment to prevent electrical leakage from interfering with plasma and RF processes.
Chip Aging Test Socket Base
Under high-temperature operating conditions of 240°C, aluminum and epoxy boards are prone to high-temperature deformation and misalignment, whereas PEEK maintains dimensional stability, provides electrical insulation for probe signals, prevents electrical leakage, and avoids probe jamming due to thermal expansion.
Mobile Phone Manufacturing Fixtures
Positioning fixtures and high-temperature carriers are exposed to instantaneous high temperatures from lasers; PEEK, when in close proximity to the heat source, does not soften, smoke, or deform, ensuring consistent positioning accuracy.
Fixtures for Lithium-Ion Battery Production Lines
The cell positioning jig features structural stops and anti-expansion pressure resistance, precisely securing each battery cell in place, with excellent insulation properties. It operates stably at 250°C over the long term and does not deform or soften under normal module operating temperatures or in short-term high-temperature environments. It is resistant to chemical corrosion and offers long-term durability.
Key Advantages of PEEK Fixtures Over Aluminum, Steel, and Bakelite
| PEEK Clamps | Aluminum Alloy Clamps | Bakelite/POM Clamps | |
| Product Protection | Does not damage high-gloss or brittle workpieces | Prone to scratching glass and plastic parts | Prone to shedding powder that can contaminate products |
| Temperature Resistance | Long-term exposure to 250°C | Deforms at temperatures ≤150°C | Softens at temperatures ≤80°C |
| Insulation and Anti-Static Properties | Insulating and anti-static | Insulating washers required for electrical conductivity | Insulating but not resistant to high-temperature solvents |
| Weight | 50% lighter than aluminum alloy | Relatively heavy | Lightweight but lacks rigidity |
| Chemical Resistance | Resistant to most solvents, acids, and alkalis | Prone to oxidation and corrosion | Prone to swelling when exposed to organic solvents |
