PP-Borealis RF365MO Precision Mold Design & Tooling Guide<\/h2>\n

Molding an optical-grade copolymer requires careful gate design and uniform mold temperature management to protect clarity and prevent sink marks:<\/p>\n

    \n
  • Preserving High Clarity (Mirror-Surface Molds):<\/strong> Any microscopic roughness on the mold core or cavity will scatter light, causing haze. Jucheng\u2019s tooling division uses hardened mirror-polished S136 stainless steel, ensuring a pristine smooth finish directly from tool release.<\/li>\n
  • Optimizing Flow & Shear Stress:<\/strong> To prevent “blush” marks and visible weld lines, we analyze gate locations via Moldflow simulation during DFM. We engineer wide valve gates or highly balanced hot runner tips to reduce local shear heating.<\/li>\n
  • Cooling & Shrinkage Controls:<\/strong> Copolymer shrinkage runs between 1.0% and 2.0% depending on part thickness. We keep mold temperatures uniform at 30\u00b0C to 40\u00b0C (86\u00b0F\u2013104\u00b0F) using CNC-machined conformal cooling loops to eliminate warpage and prevent sink marks.<\/li>\n
  • \u52a0\u5de5\u6e29\u5ea6\uff1a<\/strong> Melt temperatures are managed at 210\u00b0C\u2013260\u00b0C (410\u00b0F\u2013500\u00b0F). High-speed injection profiles are applied, supported by an optimized holding pressure of 200\u2013500 bar to secure structural density.<\/li>\n<\/ul>\n<\/section>\n
