Provided is a temperature control apparatus of a working machine that is inexpensive, energy-saving and capable of eliminating the temperature difference between a temperature in a room in which the working machine is installed and a temperature of a working area.

Temperature control apparatus of working machine

A thermoplastic polyester resin is fed into a twin extruder, wherein a resin is heated for melting, thereby removing moisture in the resin by evacuating and sucking from a vent port thereof, injecting a foaming agent into the resin to which is pushed out as a foaming sheet and, after that, forming the foaming sheet which is divided into a forming body and a trimming loss, whereby the trimming loss is crushed to obtain crushed materials which are provided so as to put the materials into the twin extruder as collection materials and recycle them.
