PEEK Machining

PEEK Machined Parts

Sunhy has a reputation for producing quality screw machine parts from PEEK plastic. We can machine intricate parts on our CNC Swiss machines and CNC turning centers.

Polyether ether ketone (PEEK) is a popular high strength plastic resin, ideal for parts that require strength and stiffness. It has an extremely high resistance to heat, moisture, and chemicals and can withstand multiple cycles in hot water or steam. PEEK also performs well in ultra-high vacuum environments.

PEEK has a machining cost factor of 0.9 when compared to steel 12L14.
