Patent ID: 8163211

Claim:
A method for manufacturing a panel comprising the steps of: spraying a coating material onto an outer thin plate; providing a non-foam material of a foamable filler on the outer thin plate; providing an inner thin plate over the outer thin plate to form a space between the inner and outer plates, wherein the space contains the non-foam material; intermittently applying a thermosetting adhesive to a perimetrical edge part of the outer thin plate, wherein the adhesive is partially and intentionally removed from the perimetrical edge part; turning up the entire perimetrical edge part of the outer thin plate to fix the perimetrical edge part to a perimetrical edge part of the inner thin plate; placing the fixed assembly into a baking coating heating device to bake the coating material and foam the non-foam material so that it fills into the space; simultaneously curing the adhesive with the baking coating heating device; and releasing air contained in the space during foaming through omissions of the adhesive.
