ST. AUGUSTIN, Germany—Hennecke Inc. has developed a high-pressure machine to mold polyurethane elastomers.
Unlike low pressure machines, the high pressure Elastoline HP machines can save material, according to the company. It also does away with the need to clean with solvents between jobs, Hennecke said.
"It is tricky to design high pressure machine components for hot temperature and elastomer processing," Frank Koester, sales manager for elastomer metering machines said in a statement. "For mixing at high pressure, one needs over 100 bar pressure. The energy of the pressure has a a massive influence on elastomer components. Mixing temperatures can be between 45°C and 100°C. At this temperature the mixture is much less viscous than at 20-25°C which is normally used."
