PC-SABIC Lexan 3412 Tooling & Glass Fiber Processing Guide<\/h2>\n

Molding an amorphous standard composite like Lexan 3412 requires strict moisture control and optimized gating to prevent abrasive tool wear and warpage:<\/p>\n

20% short glass fibers act as an abrasive medium under high injection speeds. Jucheng\u2019s tooling division prevents cavity erosion by constructing molds with premium S136 stainless tool steel hardened to 48\u201352 HRC and machined on our 5-axis CNCs, ensuring long-term parting line precision and flash-free parts.<\/p>\n<\/div>\n

\n

Eliminating Floating Fibers (Surface Quality)<\/p>\n

If the mold temperature is cold, the polymer matrix freezes too fast, allowing fibers to rise to the skin layer (causing a rough, whitish surface). We utilize dynamic high mold temperatures (80\u00b0C\u2013115\u00b0C \/ 176\u00b0F\u2013239\u00b0F) to keep the surface matrix resinous and glossy.<\/p>\n<\/div>\n

PC is highly sensitive to moisture at high melt temperatures. Wet molding results in rapid hydrolytic chain cleavage, causing severe splay, gas bubbles, and a major drop in impact strength. We desiccant dry Lexan 3412 resin at 120\u00b0C (248\u00b0F) for 3\u20134 hours, keeping moisture below 0.02%.<\/p>\n<\/div>\n

Processing barrel temperatures are maintained between 280\u00b0C and 310\u00b0C (536\u00b0F to 590\u00b0F) to ensure homogeneous melting. Mold temperatures are kept at 80\u00b0C to 110\u00b0C (176\u00b0F to 230\u00b0F) using pressurized water heaters to maximize mechanical toughness and gloss.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
