Polyethylene (PE) Manufacturing & Tooling Guide<\/h2>\n

Due to PE\u2019s semi-crystalline nature and highly dynamic molecular shrinkage, strict control of scientific molding boundaries is mandatory:<\/p>\n

    \n
  • \u4e88\u5099\u4e7e\u71e5\uff1a<\/strong> Normally not required due to PE’s low water absorption (<0.01%). If stored in high-humidity conditions, pre-dry at 70\u00b0C\u201380\u00b0C (158\u00b0F\u2013176\u00b0F) for 1\u20132 hours.<\/li>\n
  • \u6eb6\u878d\u6e29\u5ea6\uff1a<\/strong> Set between 180\u00b0C and 260\u00b0C (356\u00b0F to 500\u00b0F). Exceeding 280\u00b0C can result in chemical chains fracturing and material yellowing.<\/li>\n
  • \u91d1\u578b\u6e29\u5ea6\uff1a<\/strong> Managed between 20\u00b0C and 60\u00b0C (68\u00b0F to 140\u00b0F). Higher mold temperatures improve mechanical strength and gloss but increase volumetric shrinkage.<\/li>\n
  • \u53ce\u7e2e\u5236\u5fa1\uff1a<\/strong> Volumetric shrinkage is exceptionally high, typically 1.5% to 3.0% depending on part thickness and density. Jucheng\u2019s tooling engineers calculate customized drafts and gates during DFM to prevent sink marks.<\/li>\n
  • Venting Design:<\/strong> PE processing is prone to gas entrapment. Precise venting channels of 0.02mm to 0.03mm are machined on the mold parting lines to prevent diesel burns.<\/li>\n<\/ul>\n<\/section>\n

    • Medical & Laboratory (ISO 13485):<\/strong> Disposable pipettes, diagnostic cassettes, protective syringe caps, sample tubes, and reagent bottle closures.<\/li>\n
    • Automotive Engineering (IATF 16949):<\/strong> Windshield washer fluid reservoirs, expansion tanks, protective wire harness shields, and inner trim brackets.<\/li>\n
    • Packaging & Closures:<\/strong> Child-resistant pharmaceutical caps, living-hinge snap-top closures, chemical-resistant containers, and food storage containers.<\/li>\n
    • Consumer & Outdoor Gear:<\/strong> Heavy-duty logistics crates, structural household brackets, impact-resistant protective cases, and sports equipment.<\/li>\n<\/ul>\n<\/section>\n<\/div>","protected":false},"excerpt":{"rendered":"
