For gears and general mechanism parts PA66 usually wins; for parts that need impact at low temperature, PA6 is often the better choice.<\/p>\n<h3>How much glass fill do you recommend?<\/h3>\n<p>30 % is the default for structural parts and gives the best balance of stiffness, impact and cost. Go to 50 % only when the load path genuinely needs it \u2014 surface finish and weld-line strength both suffer.<\/p>\n<\/p><\/div>\n<h2>Related materials<\/h2>\n<ul class=\"related\">\n<li><a href=\"\/tr\/abs-injection-molding\/\">ABS Injection Molding<\/a><\/li>\n<li><a href=\"\/tr\/pc-injection-molding\/\">PC Injection Molding<\/a><\/li>\n<li><a href=\"\/tr\/pp-injection-molding\/\">PP Injection Molding<\/a><\/li>\n<li><a href=\"\/tr\/pe-injection-molding\/\">PE Injection Molding<\/a><\/li>\n<li><a href=\"\/tr\/pom-acetal-injection-molding\/\">POM Injection Molding<\/a><\/li>\n<li><a href=\"\/tr\/acrylic-pmma-injection-molding\/\">PMMA Acrylic Injection Molding<\/a><\/li>\n<\/ul>\n<p><a href=\"\/tr\/injection-molding\/\">\u2190 All Injection Molding Solutions<\/a><\/p>\n<div class=\"cta\">\n<h2>Send us your Nylon drawing<\/h2>\n<p>Upload a 3D model or a 2D drawing and we will come back with a DFM review, a tooling cost and a piece price \u2014 usually within two working days.<\/p>\n<p>    <a class=\"btn\" href=\"\/tr\/iletisim\/\">Request a quote<\/a>\n  <\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Nylon is the material engineers specify when a part has to move.
