TPU-BASF Elastollan 1185A Tooling & Process Optimization Guide<\/h2>\n

Molding an amorphous high-performance elastomer like Elastollan 1185A requires strict thermal boundaries and low-stress mold setups to prevent flashing:<\/p>\n

Because Elastollan 1185A has high 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

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\u2013220\u00b0C.<\/p>\n<\/div>\n

TPU is highly hygroscopic. Moisture causes hydrolytic polymer chain cleavage, making surgical parts brittle. We dry raw material in desiccant hopper dryers at 80\u00b0C\u201390\u00b0C (176\u00b0F to 194\u00b0F) for 2\u20133 hours, keeping moisture below 0.02% before molding, protecting dynamic mechanical tensile bonds.<\/p>\n<\/div>\n

Like standard TPU, Elastollan 1185A 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
