Ipsen China has begun work on several furnaces for a European automobile manufacturer and a top worldwide automotive OEM. Ipsen China will deliver a total of five pusher furnaces, all reaching completion within one month of each other. These atmosphere heat-treatment furnaces will all be installed and operational in 2014. Three furnaces will be used to heat treat automotive transmissions, and the other two will be used to heat treat rear-axle gears. These bottom charging, preheating, fully automatic carburizing furnaces keep atmosphere consistent and processes uniform. They have tight-fitting doors and multiple zones (a heating, hardening and two carburizing zones) that provide improved control and short cycle times.
