PVDF sits between ordinary engineering plastics and the fluoropolymers: chemically tough like PTFE but with better strength and stiffness. That combination shapes how it machines.
PVDF (polyvinylidene fluoride) is a semi-crystalline fluoropolymer with excellent chemical resistance, good UV stability and useful dielectric properties. It is common in semiconductor wet-process equipment, chemical and fluid handling, and components where purity and chemical exposure matter together.
Sharp, high-positive tooling and controlled surface speed to cut rather than rub; light, distributed clamping with soft jaws; cooling where heat builds; and a deburring method matched to the part — fine features are protected from abrasive tumbling. Parts are measured after they have settled, on a temperature-controlled CMM.
Plastic tolerances are quoted realistically rather than optimistically: machined plastics are typically held to around ±0.05 mm on critical features, and tighter values are discussed per part, because thermal expansion and stiffness set a physical limit that no machine overrides.
