PC-Sabic Lexan 141R Tooling & Demolding Optimization Guide<\/h2>\n

While Lexan 141R contains an internal release agent, its high melt viscosity and amorphous nature require precise engineering parameters to prevent stresses and drag marks:<\/p>\n

    \n
  • Compensating for Amorphous Shrinkage:<\/strong> Polycarbonate has low, uniform shrinkage (typically 0.5% to 0.7%). Jucheng’s tooling division uses 5-axis CNC machines to mill precise mold cavities with conformal cooling loops, preventing uneven cooling and thermal warping.<\/li>\n
  • \u53b3\u683c\u306a\u4e88\u5099\u4e7e\u71e5\uff1a<\/strong> PC is highly hygroscopic. Moisture levels must be kept strictly below 0.02% to prevent hydrolytic degradation, splay, and bubbles. We dry the raw resin in desiccant hopper dryers at 120\u00b0C (248\u00b0F) for 3\u20134 hours prior to molding.<\/li>\n
  • \u6eb6\u878d\u6e29\u5ea6\u3068\u91d1\u578b\u6e29\u5ea6\u306e\u5236\u5fa1\uff1a<\/strong> Processing barrel temperatures are maintained between 280\u00b0C and 320\u00b0C (536\u00b0F to 608\u00b0F). Mold temperatures are kept at 80\u00b0C to 120\u00b0C (176\u00b0F to 248\u00b0F) to ensure maximum gloss and reduce residual internal molding stresses.<\/li>\n
  • Optimizing Draft & Ejection:<\/strong> Because PC contracts tightly onto cores during cooling, deep-draw parts require draft angles of at least 1.5\u00b0 to 2\u00b0. S136 stainless steel mold cavity blocks, mirror-polished, are used to prevent drag marks.<\/li>\n<\/ul>\n<\/section>\n
