PURPOSE:To quickly set irradiated gelcoat and the like by uniformly heating respective parts of stock resin by a method wherein the setting of the stock is accelerated by irradiating infrared rays over thermosetting synthetic resin stock before setting. CONSTITUTION:By turning the ON/OFF switch 23 of a control device 13 ON under the condition that a form B, onto which gelcoat has been applied, is positioned below the far infrared radiators 12 of a far infrared curing device A by being seated on a work table 11, the far infrared radiators 12 are heated by the electric current sent from a power source 18, resulting in irradiating far infrared rays over the gelcoat. In this case, the far infrared rays are recognized with a remote measuring thermometer 19, resulting in allowing to input the temperature signal of the far infrared radiators 12 in a controlling circuit section 24, which actuates the tap changing-over motor 21 of a variable transformer 20 so as to control the electric current applied to the heaters 15 at the far infrared radiators 12 in order to feed-back control the temperature of the far infrared radiators 12 by aiming at the set temperature of a temperature setter 22, resulting in radiating far infrared rays having the desired wavelength from the far infrared radiators 12 so as to allow to remarkably accelerate the setting of the gelcoat. |
