Fabrication Guidelines for Nylon 6\/6 (PA66)<\/h3>\n

Moisture & Tolerance Control:<\/strong>
\nPA66 is hygroscopic and will swell as it absorbs moisture. Tip:<\/strong> We recommend machining parts “dry-to-print” and accounting for approximately 1.5% to 2% dimensional growth in humid assembly environments.<\/p>\n

Heat Management:<\/strong>
\nWhile PA66 has a higher melting point (260\u00b0C) than PA6, it is still heat-sensitive. Tip:<\/strong> We use ultra-sharp, high-rake carbide tools and abundant coolant to prevent surface melting and “gumming” of the cutting flutes.<\/p>\n

Stress Relieving:<\/strong>
\nExtruded PA66 rod and plate often contain internal stresses. Tip:<\/strong> For parts with critical flatnesses, Jucheng utilizes a rough-machining followed by a resting period or annealing cycle before final finishing.<\/p>\n

Deburring Strategy:<\/strong>
\nNylon 6\/6 is tough and produces stringy burrs. Tip:<\/strong> We utilize specialized high-speed routing and manual trimming under magnification to ensure all edges are clean and burr-free for electronic assemblies.<\/p>\n<\/div>\n

Primary Applications<\/h3>\n

Automotive Engine Zone<\/strong>
\nConnectors, wire loom holders, and fluid reservoirs that must withstand heat, oils, and vibrations under the hood.<\/p>\n

Industrial Drive Systems<\/strong>
\nGears, sprockets, and pulleys where PA66’s high strength and self-lubricating properties reduce noise and maintenance.<\/p>\n

Electrical & Electronics<\/strong>
\nInsulators, terminal blocks, and connector housings requiring high dielectric strength and UL94 flammability compliance.<\/p>\n

Consumer Appliances<\/strong>
\nMoving mechanical parts in washing machines, dishwashers, and power tools where toughness and chemical resistance are key.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
