ていた。However, bonding using adhesive requires pretreatment of the joint surface, and the adhesive must be applied uniformly.
``Furthermore, it is difficult to work because the cracks that occur after joining must be treated, and there are problems with stability due to the large joint strength. Mechanical fastening methods also require pilot holes to be drilled at the joints, and Many problems remained in the process, such as the need to align holes, insert parts, and perform fastening work.

材は強固に接合されろ。Then, due to the heat, only a portion of the plastic material becomes soft and fluid, and this portion has a high deformability. When a joining member (for example, a bottle) is pushed into such a portion, the plastic material flows into a convex or concave locking portion formed on the outer peripheral surface or inner surface of the joining member and fills the locking portion. Cool and solidify in this state. The fixed plastic material flowing into the locking portion works together with the locking portion to generate a mechanical restraining force, and the plurality of plastic materials are firmly joined.
