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

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

Gestion de l'usure abrasive \u00e9lev\u00e9e des fibres<\/p>\n

Les fibres de verre courtes 40% agissent comme un milieu abrasif \u00e0 des vitesses d'injection \u00e9lev\u00e9es. La division outillage de Jucheng \u00e9vite l'\u00e9rosion de la cavit\u00e9 en construisant des moules en acier \u00e0 outils tremp\u00e9 de qualit\u00e9 sup\u00e9rieure (H13) trait\u00e9 thermiquement \u00e0 50\u201352 HRC et poli miroir, garantissant une pr\u00e9cision \u00e0 long terme du plan de joint et des pi\u00e8ces sans bavures.<\/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

\n

Pr\u00e9-s\u00e9chage et \u00c9vents de D\u00e9gazage<\/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
