Working principle of different types of die furnace

The mold furnace heated by electricity generates heat through the electricity through the heating body and transfers heat to the mold through convection and radiation. Common heating bodies include heaters made of superalloy wires, which are heated and transmit heat around the heat.

The gas-heated mold furnace produces high temperature flame and flue gas by burning natural gas or liquefied gas, and these high temperature media transfer heat to the mold by radiation and convection. Gas heating furnace is usually equipped with inlet burner and high pressure fan, forming hot air circulation, uniform heating mold

Electromagnetic heating uses the principle of electromagnetic induction to generate induced eddy currents inside the mold, which generates heat and heat the mold. This technology has the advantages of fast heating speed, accurate temperature control and energy saving.

The trolley-type mold preheating furnace is installed on the stage car through the workpiece, and the intelligent temperature control system is started. The internal circulation fan works, the heating system is opened, and the furnace heats up quickly. The hot air circulation forms a evenly distributed dry and hot flowing air layer to complete the transfer of heat and quality.
