Fabrication Guidelines for Ultem 1000<\/h3>\n

Coolant Sensitivity:<\/strong>
\nUltem is highly sensitive to certain oils and solvents, which can cause immediate stress cracking (crazing). Tip:<\/strong> We use strictly compatible water-soluble coolants or air-blast cooling to ensure material integrity.<\/p>\n

Annealing Requirements:<\/strong>
\nMachining induces internal stress in PEI. Tip:<\/strong> For parts with tight tolerances or complex geometry, we perform in-process annealing to relieve stress and prevent warping after the final cut.<\/p>\n

Tooling Selection:<\/strong>
\nUltem is relatively brittle and abrasive. Tip:<\/strong> We use sharp, positive-rake carbide tools with polished flutes to shear the material cleanly, preventing heat buildup and surface smearing.<\/p>\n

Clamping Care:<\/strong>
\nUltem can crack under localized high pressure. Tip:<\/strong> We utilize vacuum tables or soft-jaws with distributed pressure to hold parts securely without inducing stress risers.<\/p>\n<\/div>\n

Primary Applications<\/h3>\n

Aerospace & Aviation<\/strong>
\nElectrical connectors, lighting housings, and thermal insulators requiring high flame resistance and low weight.<\/p>\n

Medical Devices (ISO 13485)<\/strong>
\nSurgical instrument handles, sterilization trays, and manifolds requiring repeated autoclaving resistance.<\/p>\n

Electronics & Semiconductor<\/strong>
\nBurn-in sockets, high-voltage switches, and wafer handling components requiring excellent dielectric properties.<\/p>\n

Food Processing<\/strong>
\nFluid manifolds and scraper blades requiring FDA compliance and resistance to hot water\/steam cleaning.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
