Induction Heater for Extruder

Specifications

Description:

Induction heaters are mainly applied to plastic (rubber) injection machine, extrusion machine, blown filming machine, wire drawing machines, plastic pipes, cables, etc. The heating method known as induction heating occurs when an electrically conductive material is placed in a varying magnetic field. Induction heating is a rapid form of heating in which a current is induced directly into the part (e.g. barrel) being heated. Induction heating is a non-contact form of heating. A typical induction heating system consists of the induction heating power supply, an induction heating coil, and a water-cooling source, which cools the coil and several internal components inside the power supply. The induction heating power supply sends alternating current through the induction coil, thus generating a magnetic field. When a work piece is placed within the coil and enters the magnetic field, eddy currents are induced within the work piece, generating precise and localized heat without any physical contact between the induction coil and the work piece. The advantages of induction heaters include 1) substantial energy-saving (save 30%-75%), 2) higher thermal efficiency, 3) lower work temperature, 4) longer usage life, 5) faster heating-up, 6) less and easier maintenance. It thus reduces total cost over the long run.
