상품상세정보

This machine is a Vacuum Rapid Heated Pressing Furnace (VRHP or RHP) designed for making dense pallets under vacuum or the protective gas environment. A 15 kW temperature controllable induction heater is integrated into the system, which provides sufficient power for rapidly heating the graphite pressing die up to 1700 ℃. The Induction coil is built inside of stainless steel vacuum chamber. An electric hydraulic press is inserted from the bottom of the chamber, providing up to 5 tons pressing force.
