PS-Trinseo STYRON A-tech 1175 Tooling & Flow Line Prevention Guide<\/h2>\n

STYRON A-tech 1175 is an amorphous HIPS with a low mold shrinkage rate, but managing weld-line weakness and internal stresses is key to preserving its ESCR properties:<\/p>\n

    \n
  • Optimizing Weld Line Integrity:<\/strong> In refrigeration and food contact parts, weld lines (where melt flows meet) are highly vulnerable to stress cracking. Jucheng\u2019s tooling division conducts extensive Moldflow simulations during our free 24-hour DFM phase to position gates strategically, shifting weld lines away from high-stress areas.<\/li>\n
  • Mold Temperature Control (Surface Gloss):<\/strong> We maintain elevated mold temperatures at 40\u00b0C\u201365\u00b0C (104\u00b0F to 149\u00b0F) using pressurized temperature controllers. High mold temperatures maximize surface gloss, reduce flow marks, and minimize molded-in residual stresses.<\/li>\n
  • \u79d1\u5b66\u7684\u306a\u5c04\u51fa\u30d7\u30ed\u30d5\u30a1\u30a4\u30ea\u30f3\u30b0\uff1a<\/strong> Processing melt temperatures are kept between 200\u00b0C and 250\u00b0C (392\u00b0F to 482\u00b0F). Slow to moderate injection speeds combined with progressive packing pressures are applied to avoid rubber-phase shear degradation.<\/li>\n
  • \u4e88\u6e2c\u53ef\u80fd\u306a\u4f4e\u53ce\u7e2e\u7387\uff1a<\/strong> STYRON A-tech 1175 exhibits a low, uniform shrinkage rate of 0.4% to 0.8%. This enables our 5-axis CNC machining center to cut precise, tight-tolerance mold cavities.<\/li>\n<\/ul>\n<\/section>\n
