AI Technical Summary
In existing technologies, the heat dissipation during billet transfer is severe, and the temperature fluctuates greatly. Traditional heating methods have slow heating rates, low temperature control accuracy, uneven heating of molds, and short service life.
Electromagnetic induction coils are used to heat the billet and mold in situ. Combined with a feedback adjustment system, rapid heating and precise temperature control are achieved. Positioning and guidance are provided by a bracket and a cylindrical graphite pad, and a chamfered structure is designed to reduce flow resistance.
It achieves rapid heating of the billet and stable temperature control, reduces heat loss and thermal stress damage to the mold, improves forming quality and mold life, and shortens the thermoforming cycle.
