TPU-Lubrizol Estane 58211 Tooling & Processing Guide<\/h2>\n

Molding an amorphous high-performance elastomer like Estane 58211 requires strict thermal boundaries and low-stress mold setups to prevent flashing:<\/p>\n

Controle de Rebarbas em N\u00edvel de M\u00edcron (Precis\u00e3o de Ferramentas)<\/p>\n

Because Estane 58211 has exceptional flow capabilities, the molten resin can seep easily into minor mold gaps, causing parting line flash. Jucheng\u2019s tooling division uses 5-axis CNC machines to achieve micro-tolerances, keeping mold parting clearances strictly within 0.005mm on premium S136 stainless steel mold cavity blocks.<\/p>\n<\/div>\n

\n

Mold Temperature Matrix (Crystallization)<\/p>\n

We maintain mold temperatures at 20\u00b0C\u201340\u00b0C (68\u00b0F to 104\u00b0F) using pressurized water chillers. Keeping tools cold is critical to freeze the soft elastomeric phase quickly, allowing for automatic, warp-free ejection. Melt temperatures are controlled at 190\u00b0C\u2013210\u00b0C.<\/p>\n<\/div>\n

\n

Protocolo de Secagem com Dessecante (Preven\u00e7\u00e3o de Hidr\u00f3lise)<\/p>\n

TPU is highly hygroscopic. Moisture causes hydrolytic polymer chain cleavage, making surgical parts brittle. We dry raw material in desiccant hopper dryers at 100\u00b0C\u2013110\u00b0C (212\u00b0F to 230\u00b0F) for 3\u20134 hours, keeping moisture below 0.02% before molding, protecting dynamic mechanical tensile bonds.<\/p>\n<\/div>\n

Compensa\u00e7\u00e3o de Alta Retra\u00e7\u00e3o El\u00e1stica<\/p>\n

Like standard TPU, Estane 58211 exhibits high shrinkage (typically 1.0% to 2.0% depending on hardness and grade). Our tooling division scales mold cavities precisely to compensate for this shrinkage, ensuring exact dimensional results verified by Zeiss CMM.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
