LCP-Sumitomo Sumikasuper E6008 High-Frequency Dielectric & Micro-Flash Matrix<\/h2>\n

Molding an ultra-high heat resistant, 40% glass-fiber reinforced LCP like Sumikasuper E6008 requires precise gating, extreme thermal limits, and advanced venting to prevent outgassing:<\/p>\n

Contr\u00f4le des bavures au niveau micron (pr\u00e9cision d'outillage)<\/p>\n

Because Sumikasuper E6008 exhibits extreme flowability (low viscosity) during peak standard molding at 360\u00b0C, molten resin can seep easily into minor mold gaps, causing parting line flash. Jucheng\u2019s tooling division uses 5-axis CNC machines to achieve micro-tolerances, keeping mold parting clearances strictly within 0.005mm on premium S136 stainless steel mold cavity blocks.<\/p>\n<\/div>\n

Matrice de contr\u00f4le uniforme de la temp\u00e9rature<\/p>\n

We maintain mold temperatures at 80\u00b0C\u2013120\u00b0C (preferably 110\u00b0C\/230\u00b0F) using pressurized oil temperature controllers. High mold temperatures maximize surface gloss, reduce weld lines, and prevent surface glass-fibers from floating, ensuring a smooth and non-fibrous finish.<\/p>\n<\/div>\n
