ABSTRACT:
An insulated mold for thermoplastics, has a recessed mold area and an elevated land area. An insulating material is deposited in the mold area and a hard layer of metal is deposited on the insulating layer. The land protects the insulating layer from delamination. Also, in some embodiments, a transition between the land and the recessed mold area is provided. The protective member may also be employed to hold down the edge of the insulating layer and to shield the edge from molten thermal plastics, thereby preventing delamination.
