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
  • Ph\u00e2n t\u00edch phun khoa h\u1ecdc:<\/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
  • Predictable Low Shrinkage:<\/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
