Polyphenylene Sulfide (PPS) Injection Molding Guide<\/h2>\n

PPS’s high fluidity makes it highly susceptible to flashing, while its semi-crystalline structure demands rigorous mold temperature control:<\/p>\n

    \n
  • S\u1ea5y Tr\u01b0\u1edbc:<\/strong> While PPS has low water absorption, we dry raw resin at 120\u00b0C\u2013140\u00b0C (248\u00b0F\u2013284\u00b0F) for 3\u20134 hours. This eliminates surface splay and prevents weld-line micro-voids, securing cosmetic and physical perfection.<\/li>\n
  • Nhi\u1ec7t \u0111\u1ed9 n\u00f3ng ch\u1ea3y:<\/strong> Set between 295\u00b0C and 330\u00b0C (563\u00b0F to 626\u00b0F). Processing temperatures must not exceed 350\u00b0C to prevent thermal degradation and outgassing.<\/li>\n
  • Nhi\u1ec7t \u0111\u1ed9 khu\u00f4n t\u1edbi h\u1ea1n:<\/strong> Pressurized oil heaters are mandatory to keep mold temperatures at 120\u00b0C\u2013150\u00b0C (248\u00b0F to 302\u00b0F). Low mold temperatures (below 90\u00b0C) prevent correct crystalline formulation, severely degrading structural rigidity and heat deflection properties.<\/li>\n
  • Micron-Level Flash Control:<\/strong> Due to PPS’s low melt viscosity, flash can occur even at mold gaps as small as 0.01mm. Jucheng\u2019s in-house tooling division uses 5-axis CNC machines to achieve ultra-tight tolerances (parting line clearances within 0.005mm) to secure zero-flash parts.<\/li>\n
  • Low Shrinkage:<\/strong> Volumetric shrinkage is exceptionally low (typically 0.2% to 0.5% for GF40 grades). The extremely high dimensional stability makes PPS an ideal replacement for aluminum castings.<\/li>\n<\/ul>\n<\/section>\n

    • Fluid & Chemical Handling:<\/strong> Chemical chemical pump housings, boiler water mixing valves, gas flow meters, hot-water pump gears, and high-pressure gaskets.<\/li>\n
