Description of the Related Art Conventionally, plastic moldings have been widely used in various fields such as automobile materials, building materials, electrical products, and particularly aluminum sash frames, automobile window frames, various switches and knobs for electrical products. As shown in the figure, the part to be attached to the main body is made of hard and tough hard plastic, and the other part is made of soft plastic or elastomer such as rubber to prevent rainwater from entering or to be touched by human hands. In many cases, it is made to feel good, and even if it is hit by the human body, there is no injury or damage to the material.

In the case of the integration method using an adhesive, since both members are different from each other, defective adhesion often occurs and defective products often occur. In addition, since an organic solvent is used in almost all cases when using an adhesive, it is not preferable in terms of hygiene, and it is very complicated in manufacturing. In addition, in the method of fitting both members, the mold for forming each member is complicated and expensive, and the fitting work is very complicated. Therefore, there is a strong demand for a method capable of providing a composite plastic molded product composed of a hard plastic and a soft plastic without using the adhesive or the male-female type fitting as described above.

である。Conventionally, a very large number of hard plastics and a very large number of soft plastics are known, and it is considered that it is impossible to simply bond the two by fusion. In particular, the non-polar material such as polypropylene resin is almost impossible to be bonded except for the same kind, but according to the detailed study of the present inventor, such an inert polypropylene resin can be used. On the other hand, among various soft plastics, it was found that only a thermoplastic elastomer was easily fused.
