De-wax Furnace

Horizontal vacuum de-wax furnace is used for de-wax or pre-sintering process in vacuum or in certain gas for materials such as stainless steel, cemented carbide, super alloy, heavy alloy, ceramic, magnetic alloy, carbide, boride, nitride, oxide and intermetallic compound.
       Horizontal water cooling structure is adopted in this furnace, with front door or double doors. Heat element can be graphite or NiCr alloy or other materials while heating shield can be graphite or other materials depending on working temperature and customer' demand. Heat elements are distributed in several heating zone, in which independent temperature control system with PID adjustors is adopted to ensure accurate temperature control.
       Deliberately designed multi-lever water cooled butterfly wax collector and sealed furnace body are adopted. Complete de-wax is realized by directional gas flow and avoidance of corners in the furnace.  Gas cooling system inside or outside furnace can be added to the furnace to speed up cooling of materials leading to shorter working cycle and higher efficiency.
