果を奏する。[Effects of the Invention] As explained above, according to the method for manufacturing a heat insulating profile of the present invention, the main body and the frame for forming a heat insulating part of a profile in which a frame for forming a heat insulating part is provided in the main body. A core material made of a thermoplastic resin containing a foaming agent and a surface material made of a thermoplastic resin and located between the core material and the frame for forming the heat insulating part are placed in the hollow part formed by the After heating the shape to foam the core material and forming a heat insulating part having a surface material on the outer surface, the frame for forming the heat insulating part is separated to form a heat insulating shape consisting of a main body part and a heat insulating part. There is no need to perform sizing on the insulation part.
In addition, since the material to be foamed is a solid core material, it is extremely easy to handle, and since the foaming pressure can be controlled by adjusting the mixing ratio of the foaming agent, it is easy to manage during manufacturing. In addition, it can be manufactured without using a large mold or the like, and as a result, productivity can be significantly improved and costs can be reduced. In addition, by using a surface material that foams less than the core material or does not foam, the surface of the insulation part can be molded well.
Furthermore, there are many effects such as being able to apply designs and decorations to the surface of the heat insulating part at the same time as forming the heat insulating part.
