* The net weight each piece is generally within the range of ±12%,occasionally 15% allowed. unless special requirements.
   with the wearing of the mold during the extrusion process, the weight of the products will be relatively light when the mold is new, and will be     relatively heavy after the mold is worn.
*Upper end of the ceramic honeycombs is flat, below end of the ceramic honeycombs can be Flat, with one slot , or with Cross Slots.
