Fabrication Guidelines for Delrin AF<\/h3>\n

Distinctive Appearance:<\/strong>
\nDelrin AF is typically dark brown or chocolate in color due to the PTFE fibers. \u30d2\u30f3\u30c8:<\/strong> This makes it easily distinguishable from standard white or black POM during assembly and inspection.<\/p>\n

Cutting Temperature:<\/strong>
\nWhile the PTFE fibers provide lubrication, heat buildup can still cause material softening. \u30d2\u30f3\u30c8:<\/strong> We use sharp tools and high-volume air blast or water-soluble coolant to keep the material rigid for accurate cutting.<\/p>\n

Avoid Bonding:<\/strong>
\nDue to the high Teflon content, Delrin AF is almost impossible to glue or bond. \u30d2\u30f3\u30c8:<\/strong> Design your assembly using mechanical fasteners or interference (press) fits.<\/p>\n

Environmental Stability:<\/strong>
\nLike all acetals, Delrin AF has very low moisture absorption. \u30d2\u30f3\u30c8:<\/strong> It maintains its precise dimensions even in submerged or high-humidity environments, unlike Nylon.<\/p>\n<\/div>\n

High-Speed Sliding Bearings<\/strong>
\nBushings and sleeves in office equipment and conveyors that must operate silently without liquid lubricants.<\/p>\n

Medical & Laboratory Equipment<\/strong>
\nMoving parts in diagnostic machines where grease contamination would ruin sensitive samples or sensors.<\/p>\n

Consumer Electronics<\/strong>
\nInternal sliding mechanisms for cameras, lens actuators, and high-end audio-visual equipment.<\/p>\n

Industrial Automation<\/strong>
\nGuide rails, wear strips, and cam followers that require long-term durability and a low “breakaway” force.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
