Fabrication Guidelines for Ultem<\/h3>\n

Coolant Selection:<\/strong>
\nUltem is sensitive to stress cracking. Standard petroleum-based coolants can cause immediate failure. We use non-aromatic, water-soluble coolants or air blast specifically tested for amorphous plastics.<\/p>\n

\u5de5\u5177\uff1a<\/strong>
\nCarbide tools are required, especially for glass-filled grades (Ultem 2300) which are highly abrasive. We use tools with positive rake angles to cut freely and reduce heat generation.<\/p>\n

Clamping Strategy:<\/strong>
\nTo avoid cracking, clamping forces must be distributed evenly. Soft jaws and vacuum tables are preferred. We avoid point-loads or overtightening vices.<\/p>\n

Annealing:<\/strong>
\nDue to internal stresses from the extrusion process, Ultem stock should often be annealed before machining critical dimensions to ensure the part doesn’t warp after material removal.<\/p>\n<\/div>\n

Primary Application Industries<\/h3>\n

\u822a\u7a7a\u5b87\u5b99<\/strong>
\nKey Parts:<\/em> Electrical connectors, lighting housings, air vent components.
\nWhy Ultem:<\/em> Meets strict Flame, Smoke, and Toxicity (FST) standards required for aircraft interiors.<\/p>\n

Medical Devices (ISO 13485)<\/strong>
\nKey Parts:<\/em> Surgical instrument handles, sterilization trays, endoscopic components.
\nWhy Ultem:<\/em> Can withstand repeated autoclaving (steam sterilization) cycles without degrading.<\/p>\n

Electronics<\/strong>
\nKey Parts:<\/em> High-voltage switches, connectors, coil bobbins, burn-in sockets.
\nWhy Ultem:<\/em> High dielectric strength and stable electrical properties over a wide temperature range.<\/p>\n

Food Industry<\/strong>
\nKey Parts:<\/em> Probes, manifolds, sight glasses.
\nWhy Ultem:<\/em> FDA compliance (Unfilled grades) and resistance to hot water and steam cleaning.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
