Domande frequenti (FAQ)<\/h2>\n
\n
\n
Q: What makes Ultem \/ PEI an outstanding choice for electronic and electrical environments?<\/div>\n
A: Ultem exhibits unmatched dielectric strength (making it an extraordinary high-voltage insulator) paired with a high continuous service threshold of 170\u00b0C and a natural UL94 V-0 flame rating. This makes it ideal for dense circuit housings and aerospace components where safety and isolation are mandatory.<\/div>\n<\/div>\n
\n
Q: How does AluCarbon Tech prevent chipping and cracking during Ultem machining?<\/div>\n
A: Ultem is a notoriously amorphous, rigid, and brittle plastic that easily cracks or experiences micro-crazing under high cutting stress. Our technical team prevents this by running dedicated sharp, high-rake positive tooling pathways and modifying feed parameters, combined with dry air-blast cooling to keep the part entirely free of localized thermal shocks.<\/div>\n<\/div>\n
\n
Q: Can machined PEI parts withstand repeated chemical sterilization cycles?<\/div>\n
A: Yes. Ultem 1000 is highly resistant to steam autoclaving, gamma radiation, and aggressive chemical sterilants. This makes it a preferred premium metal replacement polymer for reusable medical devices, surgical equipment, and lab fluidic blocks.<\/div>\n<\/div>\n
\n
Q: What is the standard minimum order quantity (MOQ) for custom PEI parts?<\/div>\n
A: AluCarbon Tech implements no minimum order volume. We proudly assist engineering teams globally from one-off functional prototypes for experimental validation to extensive high-volume production batches exceeding 1,000+ components.<\/div>\n<\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"
