PPS-Polyplastics Durafide 1140A6 Tooling & Flash Control Guide<\/h2>\n

Molding a linear 40% glass-fiber reinforced PPS like Durafide 1140A6 requires strict control of parting line clearances to prevent flashing, alongside high mold temperatures:<\/p>\n

\n
\n

Controllo delle bave a livello di micron (precisione dell'attrezzatura)<\/p>\n

Because Durafide 1140A6 exhibits high flowability (low melt viscosity of 260 Pa\u00b7s), 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

\n

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

Pressurized oil heaters are mandatory to keep mold temperatures at 130\u00b0C\u2013150\u00b0C (266\u00b0F to 302\u00b0F). Low mold temperatures (below 90\u00b0C) prevent the optimal semi-crystalline phase from forming, which severely degrades mechanical strength, chemical resistance, and dimensional stability over time.<\/p>\n<\/div>\n

\n

Gestione dell'usura abrasiva elevata delle fibre<\/p>\n

Le fibre corte di vetro 40% agiscono come mezzo abrasivo ad alte velocit\u00e0 di iniezione. La divisione utensili di Jucheng previene l'erosione della cavit\u00e0 costruendo stampi con acciaio per utensili premium temprato (H13) trattato termicamente a 50\u201352 HRC e lucidato a specchio, garantendo precisione della linea di divisione a lungo termine e parti senza bave.<\/p>\n<\/div>\n

\n

Essiccazione con essiccante e scarico dei volatili<\/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. Additionally, we cut precise venting slots (0.015mm depth) along the parting line to exhaust volatile gases during high-melt runs.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
