sustained contact pressure. In a seal or low-load sliding interface, that compliance may be useful; around a precision locating feature it can instead relax preload or shift the effective clearance. If PTFE remains the better chemical or friction choice, the design can respond with a larger support area, a metal or PEEK backing structure, a replaceable wear element, or a fit that is less sensitive to small movement. Validate the assembled geometry under representative load and temperature rather than assuming an unloaded machined dimension predicts service behavior.<\/p>\n<p>For close fits, specify which surfaces are functional and how the part is supported during measurement. A polymer can move with clamping force and temperature, so inspection conditions should be consistent with the drawing and the intended assembly\u2014not an improvised \u201ctight tolerance\u201d detached from use.<\/p>\n<\/section>\n<section id=\"sliding-and-chemistry\">\n<h2>\u0639\u0646\u062f\u0645\u0627 \u064a\u0647\u064a\u0645\u0646 \u0627\u0644\u0627\u0646\u0632\u0644\u0627\u0642 \u0623\u0648 \u0627\u0644\u0643\u064a\u0645\u064a\u0627\u0621<\/h2>\n<p>PTFE\u2019s low-friction and chemical-resistance profile makes it attractive for sliding, sealing, and chemically exposed parts. Its low strength relative to structural engineering plastics is the trade-off. A mating surface can also dominate wear: a rough, sharp, or contaminated counterface may damage the polymer regardless of its catalog description.

But a generic \u201cPEEK\u201d request can hide meaningful differences between unfilled, carbon-filled, glass-filled, and bearing grades. Fillers can improve one property while changing wear against a particular counterface, machining behavior, surface quality, or electrical characteristics. Match the exact grade to the contact pair and environment.<\/p>\n<p>For either polymer, check chemical compatibility against concentration, temperature, exposure duration, and stress.

PTFE\u2019s softness and tendency to deform can make thin walls, sharp corners, and clamping-sensitive features difficult to hold consistently. PEEK is more rigid, but stock condition, residual stress, heat, tool sharpness, and the order in which features are cut still matter. A deep bore released from a fixture may not measure exactly like the same bore while constrained.<\/p>\n<p>Share the part\u2019s functional datums, wall thicknesses, mating components, and the surfaces that control assembly. Agree whether a feature is measured after the part has stabilized and in what orientation. If the design needs a close fit, provide the mating size or fit range instead of asking the machine shop to infer it from an isolated nominal dimension.
