Title:

METHOD OF MANUFACTURING HOT FORMED OBJECT, AND DEVICE AND METHOD FOR CONTINUOUS HIGH-FREQUENCY HEATING.

Document Type and Number:

WIPO Patent Application WO/2002/090081

Kind Code:

A1

Abstract:

A method of manufacturing a hot formed object, comprising the steps of filling forming material into a plurality of forming dies and moving the forming dies continuously to a heating zone by a conveyor means, the heating zone being divided in a plurality of sub zones having power source means and power supply means, whereby, since a high frequency is applied from the power supply means to the forming dies, the forming material is heat-formed but, since the heating zone is divided into a plurality of parts, the occurrence of the concentration of a high frequency energy can be suppressed or avoided even if the scale of equipment is large.
