ABS-LG Chem HF380 Tooling & Cycle Time Optimization Guide<\/h2>\n

Molding an ultra-high fluidity resin like LG HF380 requires strict control of parting line clearances to prevent flashing, alongside thorough drying to prevent splay:<\/p>\n

    \n
  • Micron-Level Flash Control (Tool Precision):<\/strong> Because HF380 has high flow capabilities, the molten resin can easily seep into mold parting line gaps, causing unsightly flashing. Jucheng\u2019s tooling division uses 5-axis CNC machines to achieve extremely tight tolerances, keeping mold clearances strictly within 0.01mm on premium S136 stainless steel mold cavity blocks.<\/li>\n
  • Eliminating Moisture Splay:<\/strong> ABS is hygroscopic. We pre-dry the raw resin in desiccant hopper dryers at 70\u00b0C\u201380\u00b0C (158\u00b0F to 176\u00b0F) for 2\u20133 hours. This completely eliminates moisture-induced silver streaks and preserves high tensile strengths.<\/li>\n
  • Melt and Mold Temperature Control:<\/strong> Processing barrel temperatures are maintained between 200\u00b0C and 230\u00b0C (392\u00b0F to 446\u00b0F). Mold temperatures are kept at 40\u00b0C to 80\u00b0C (104\u00b0F to 176\u00b0F) to ensure uniform surface gloss and prevent residual thermal stresses.<\/li>\n
  • Conformal Cooling for Short Cycles:<\/strong> Highly fluid resin fills cavities rapidly, meaning cooling is the cycle bottleneck. We machine balanced, conformal cooling circuits directly into core blocks to speed up heat dissipation, further reducing cycle times.<\/li>\n<\/ul>\n<\/section>\n
