PROBLEM TO BE SOLVED: To reduce the warpage and prevent the surface crack from developing in a hardened material after curing by a method wherein an extrusion-molded body on a lower stage tray is surrounded by the leg parts and plates of the tray so as to be brought in a closed state. SOLUTION: Tray leg parts 1 and 2 are provided parallel to each other at the right and left lower parts of a carrying surface A. In addition, between the leg parts, every one plate 4 is provided at the front and the rear of a tray. An extrusion-molded body is surrounded by the tray leg parts 1 and 2 and the two plates 4. As the material of the plate 4, metal or heat resistant resin, which either deforms nor breaks under hot and humid curing conditions, is employed. In order to prevent the plate 4 from deforming due to the difference between thermal expansion coefficients, the preferable material of the plate 4 is the same as that of the tray. In order to improve the airtightness of the tray under the state that trays are stacked, a seal cushioning material 3 is especially preferably provided as some part of the plate 4 at the lower part of the plate 4. As the seal cushioning material 3, rigid rubber, foamed rubber or the like, which has elasticity and enhances the adhesion between the plate 4 and the tray 1 is preferable. |
