Fabrication Guidelines for POM-C (Copolymer)<\/h3>\n

Porosity Advantage:<\/strong>
\nUnlike Delrin, POM-C is produced without centerline porosity. Conseil :<\/strong> This is critical for parts that require pressure sealing or where bacteria could be trapped in internal voids.<\/p>\n

Chemical Resistance:<\/strong>
\nPOM-C offers better resistance to long-term exposure to hot water and high-pH (alkaline) cleaners. Conseil :<\/strong> Always specify POM-C for food processing wash-down environments or commercial plumbing components.<\/p>\n

Stabilit\u00e9 dimensionnelle :<\/strong>
\nPOM-C exhibits excellent dimensional stability due to low moisture absorption. Conseil :<\/strong> To achieve maximum precision, we recommend stress-relieved (annealed) stock, especially for large plates or asymmetrical parts.<\/p>\n

Burr Management:<\/strong>
\nWhile easy to machine, copolymer acetal can produce small, “fuzzy” burrs. Conseil :<\/strong> We utilize ultra-sharp, high-rake tools and optimized feed rates to ensure a clean, burr-free finish directly off the machine.<\/p>\n<\/div>\n

Applications principales<\/h3>\n

Food Processing Machinery<\/strong>
\nScraper blades, rollers, manifolds, and wear strips that must be FDA compliant and resistant to hot water cleaning.<\/p>\n

Composants pour dispositifs m\u00e9dicaux<\/strong>
\nInstrument handles, surgical trials, and diagnostic equipment parts requiring biocompatibility and chemical resistance.<\/p>\n

Fluid Handling & Plumbing<\/strong>
\nValve bodies, pump components, and fittings for high-pressure fluid systems where sealing integrity is vital.<\/p>\n

Automotive Fuel Systems<\/strong>
\nComponents requiring resistance to fuels, solvents, and environmental moisture over long service lives.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
