f:i'l! Since the bond is bonded and the pressure is applied, the force is strong and the force is increased (1).In contrast, in the case of bonding outside the mold, although the resin itself is in a softened state in the contact area of the resin, The temperature is lower than that of the iCB inside the mold, and the bonding force is inevitably excessive because the iCB is discharged into the flame and the pressure is released.In addition, in the case of foam, it As the temperature drops during discharge and foaming, the bond becomes even weaker.

In other words, a large number of resin strips are gathered outside the mold and the individual strips are joined together using the so-called all-outside-mold joining method, while different resins are joined inside the mold and joined under high temperature and pressure. We are trying to achieve the same bonding strength as the so-called in-mold bonding method.
