With the progress of the times, the requirements of people on home decoration are increasing day by day. In the indoor home industry, a special-shaped piece is a decoration which is often used. At present, the special-shaped piece is mostly made of wood or plate materials and then cut and polished to be made into a desired shape. But wood or composite boards are easily deformed, cracked, not waterproof, not damp-proof. An improved way is to make the dysmorphism piece after opening the grinding apparatus with glass steel, and this kind of way has solved deformation, fracture, dampproofing and waterproofing's problem, but the inside cavity of dysmorphism piece has hollow reverberation when knocking, greatly reduced customer's user experience. Another improved method is to make the shaped decoration from metal. Simple small-size cube metal makes the piece, and its hollow inside can fill panel, aluminium honeycomb, makes its sheet metal more firm, non-deformable, and the sensation of knocking is like solid panel. However, the inner space of the special-shaped piece is different in size, and the corners of the special-shaped piece cannot be filled with the special-shaped piece, so that the special-shaped piece is partially hollow. For large-sized metal fabricated parts, the interior thereof cannot be filled with sheets and aluminum honeycombs. Large-format metal articles are therefore usually hollow in the building material industry. The hollow position obviously feels hollow when the knocking sound is generated in the using and selling processes, and the experience sense defect of the furniture is caused.
