How this part is made
Resin Selection
Premium, unreinforced polyetheretherketone (PEEK) resins are sourced to ensure structural integrity.
Extrusion Molding
PEEK resin is extruded into dense rods under high temperatures, maintaining material purity.
Thermal Annealing
Extruded PEEK rods undergo annealing to relieve internal stresses, ensuring dimensional stability.
Precision Grinding
CNC lathes machine the blanks, and centerless grinders achieve spherical roundness and surface quality.
Quality Audit
Spheres are checked for roundness and diameter using digital micrometers and roundness gauges.
Material selection notes
The polyether ether ketone (PEEK) material utilized in PEEK Ball exhibits exceptional dielectric insulation (up to 80 kV/mm) and zero moisture absorption (<0.01%). It withstands thermal cycling between cryogenic temperatures and +260°C without embrittlement or dimensional degradation in demanding industrial environments.

Frequently Asked Questions
What is the largest PEEK Ball you manufacture?
We manufacture PEEK Balls up to 310mm diameter — one of the largest sizes available globally from any PEEK Ball manufacturer. Standard sizes from 5mm to 310mm available with large-diameter sizes (150mm, 200mm, 250mm, 300mm, 310mm) particularly suited for high-pressure industrial valve applications.
Can PEEK Balls replace stainless steel balls in corrosive chemical valves?
Yes. PEEK Balls are used to replace stainless steel balls in valves handling acids, chloride solutions, and aggressive chemicals where steel corrodes. PEEK is lighter, non-corrosive, chemically resistant, and dimensionally stable — preferred for chemical service where both corrosion resistance and mechanical strength are required.
Are PEEK Balls suitable for steam sterilization?
Yes. PEEK is hydrolysis-resistant and withstands repeated SIP (steam-in-place) sterilization cycles — used in pharmaceutical process valves and food equipment requiring autoclave sterilization.
What is the difference between PEEK Ball and PTFE Ball?
PEEK Balls are mechanically stronger (tensile up to 100 MPa) and better for high-pressure applications. PTFE Balls have lower friction and broader chemical resistance including HF acid resistance. Both are manufactured by HEMSUN from 5mm to 310mm diameter.
What makes PEEK better than other engineering plastics?
PEEK offers a unique combination of high mechanical strength, creep resistance, high-temperature resistance (+250°C), and chemical inertness.
Is PEEK resistant to acids and bases?
Yes. PEEK has excellent chemical resistance to a wide range of organic solvents, acids, and bases, although it is soluble in concentrated sulfuric acid.
What is the maximum operating temperature of PEEK balls?
PEEK balls can operate continuously at temperatures up to +250°C, and can withstand short-term exposure up to +300°C.
Do PEEK balls absorb water?
PEEK has very low moisture absorption (less than 0.1% at saturation), making it extremely stable in steam and water applications.
Are PEEK balls food safe and biocompatible?
Yes. Unreinforced PEEK is inherently food safe, biocompatible, and USP Class VI compliant, making it standard in chromatography and medical devices.
Why are PEEK balls more expensive than PTFE?
PEEK resin is a premium specialty polymer with high raw material cost, and it requires high temperatures and specialized equipment to extrude and grind.
