Polyamide (PA\/Nylon) Injection Molding Manufacturing Guide<\/h2>\n

Nylon is highly hygroscopic and highly crystalline. Failure to control moisture or thermal crystallization parameters will lead to surface splay and mechanical degradation:<\/p>\n

    \n
  • S\u1ea5y Tr\u01b0\u1edbc:<\/strong> Nylon absorbs atmospheric moisture aggressively. Moisture levels must be kept below 0.20% (ideally <0.10% for structural parts) to prevent polymer chain degradation. Dry in desiccant dryers at 80\u00b0C\u2013100\u00b0C (176\u00b0F to 212\u00b0F) for 4\u20136 hours.<\/li>\n
  • Nhi\u1ec7t \u0111\u1ed9 n\u00f3ng ch\u1ea3y:<\/strong> Processed between 230\u00b0C and 280\u00b0C (446\u00b0F to 536\u00b0F) for PA6, and 260\u00b0C to 300\u00b0C (500\u00b0F to 572\u00b0F) for PA66. Exceeding 310\u00b0C will result in polymer thermal decomposition.<\/li>\n
  • Nhi\u1ec7t \u0111\u1ed9 khu\u00f4n:<\/strong> Managed between 60\u00b0C and 100\u00b0C (140\u00b0F to 212\u00b0F). For glass-filled grades, mold temperatures up to 120\u00b0C are recommended to prevent glass fibers from floating to the surface, ensuring a smooth and glossy finish.<\/li>\n
  • T\u00ednh to\u00e1n \u0111\u1ed9 co ng\u00f3t:<\/strong> Nylon’s shrinkage is high and anisotropic (1.0% to 2.5% for unreinforced grades, reducing to 0.3% to 0.8% with 30% glass filling). Tooling designs must be strictly optimized for each specific grade.<\/li>\n
  • Post-Molding Moisture Conditioning:<\/strong> Nylon components absorb ambient moisture post-molding, which increases toughness but slightly swells dimensions. Our engineers calculate this dimensional variance beforehand to ensure end-use accuracy.<\/li>\n<\/ul>\n<\/section>\n
