High-Temp Crystallization & Flash Prevention Matrix<\/h2>\n

Molding an ultra-high heat resistant, 40% glass-fiber reinforced PPS like Torelina A504FG requires strict mold temperature control and abrasive-wear prevention:<\/p>\n

Because Torelina A504FG exhibits extreme flowability (low viscosity) during peak standard molding at 310\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

Oil-Heated Mold Temperature Matrix (Crystallization)<\/p>\n

We maintain mold temperatures at 130\u00b0C\u2013150\u00b0C (266\u00b0F to 302\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

\uc608\ube44 \uac74\uc870 \ubc0f \ud0c8\uae30 \ubca4\ud305<\/p>\n

We dry raw resin in desiccant hopper dryers at 120\u00b0C\u2013140\u00b0C (248\u00b0F\u2013284\u00b0F) for 3\u20134 hours. This eliminates surface splay and prevents weld-line micro-voids, keeping internal moisture strictly below 0.02%. Precise venting slots (0.015mm depth) are cut along parting lines to exhaust gas during high-melt runs.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
