TPU-BASF Elastollan 1185A Tooling & Process Optimization Guide
Molding an amorphous high-performance elastomer like Elastollan 1185A requires strict thermal boundaries and low-stress mold setups to prevent flashing:
미크론 수준 플래시 제어(툴링 정밀도)
Because Elastollan 1185A has high flow capabilities, the molten resin can seep easily into minor mold gaps, causing parting line flash. Jucheng’s 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.
금형 온도 매트릭스(냉각 제어)
We maintain mold temperatures at 20°C–40°C (68°F to 104°F) 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°C–220°C.
건조제 건조 프로토콜(가수분해 방지)
TPU is highly hygroscopic. Moisture causes hydrolytic polymer chain cleavage, making surgical parts brittle. We dry raw material in desiccant hopper dryers at 80°C–90°C (176°F to 194°F) for 2–3 hours, keeping moisture below 0.02% before molding, protecting dynamic mechanical tensile bonds.
고탄성 수축 보상
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.
Key Application Fields for TPU-BASF Elastollan 1185A
- Municipal Fluids & Potable Water Systems: Faucet mixing valve seals, water meter connection rings, domestic water piping gaskets, chemical-resistant hoses, and couplers.
- Automotive Engineering & Under-the-Hood (IATF 16949): High-temperature dust bellows, steering rack protective sleeves, vibration-damping grommets, and chassis oil seals.
- Medical Diagnostics & Food Service: Biocompatible fluid connector seals, food-safe storage gaskets, medical monitor dampers, and drug-delivery syringe seals.
