Fabrication Guidelines for Nylon<\/h3>\n

Moisture Management:<\/strong>
\nNylon absorbs water (hygroscopic), which causes it to swell. We recommend machining dry stock and accounting for approx. 2-3% growth in humid environments during the design phase.<\/p>\n

Coolant Strategy:<\/strong>
\nNylon has a relatively low melting point compared to high-performance plastics. Sharp tools and abundant coolant are essential to prevent the material from melting and gumming up the cutter.<\/p>\n

Tooling:<\/strong>
\nVery sharp, positive rake HSS or Carbide tools are best. Dull tools will generate excess heat, causing the nylon to smear and leaving a poor surface finish.<\/p>\n

Deburring:<\/strong>
\nNylon can be difficult to deburr because burrs tend to fold over rather than break off. We use specialized cryogenic deburring or manual trimming to ensure clean edges.<\/p>\n<\/div>\n

Primary Application Industries<\/h3>\n

Automotive<\/strong>
\nKey Parts:<\/em> Air intake manifolds, engine covers, oil pans, bushings.
\nWhy Nylon:<\/em> Withstands high temperatures and oil exposure while significantly reducing vehicle weight.<\/p>\n

Industrial Machinery<\/strong>
\nKey Parts:<\/em> Conveyor rollers, wear pads, pulleys, gears.
\nWhy Nylon:<\/em> High wear resistance and self-lubricating properties reduce maintenance downtime.<\/p>\n

Electrical & Electronics<\/strong>
\nKey Parts:<\/em> Coil bobbins, cable ties, insulating washers, connector housings.
\nWhy Nylon:<\/em> Good dielectric strength and toughness make it ideal for protecting electrical components.<\/p>\n

Consumer Products<\/strong>
\nKey Parts:<\/em> Power tool housings, sports equipment bindings, furniture casters.
\nWhy Nylon:<\/em> Impact resistance ensures durability against drops and heavy usage.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
