Liquid Crystal Polymer (LCP) Manufacturing & Tooling Guide<\/h2>\n

LCP\u2019s highly oriented molecular chains in the melt state provide great strength, but also lead to unique challenges like anisotropic shrinkage and weld-line weakness:<\/p>\n

    \n
  • S\u1ea5y Tr\u01b0\u1edbc:<\/strong> LCP is slightly hygroscopic. We pre-dry the resin in desiccant dryers at 140\u00b0C\u2013160\u00b0C (284\u00b0F\u2013320\u00b0F) for 4\u20136 hours, maintaining moisture levels under 0.01% to prevent visual splay and mechanical weakness.<\/li>\n
  • Nhi\u1ec7t \u0111\u1ed9 n\u00f3ng ch\u1ea3y:<\/strong> Managed between 310\u00b0C and 360\u00b0C (590\u00b0F to 680\u00b0F) depending on the specific LCP type (Type I vs Type II polymer structures).<\/li>\n
  • Nhi\u1ec7t \u0111\u1ed9 khu\u00f4n:<\/strong> Managed between 60\u00b0C and 120\u00b0C (140\u00b0F to 248\u00b0F). Higher mold temperatures are recommended for high-temperature LCP grades to improve molecular blending at weld lines.<\/li>\n
  • Weld-Line Management:<\/strong> LCP molecules align heavily along the flow direction. This orientation causes weld lines (where two flow fronts meet) to be mechanically weak. Jucheng\u2019s tooling engineers utilize advanced Moldflow analysis to position gates strategically, shifting weld lines away from load-bearing structures.<\/li>\n
  • Anisotropic Shrinkage Control:<\/strong> Shrinkage is almost zero in the flow direction (0.0% to 0.1%), but perpendicular to the flow, it can reach 0.3% to 0.5%. Our in-house tooling division uses 5-axis CNC machines to precisely machine mold dimensions to compensate for this variance.<\/li>\n<\/ul>\n<\/section>\n
