- the existing continuous extrusion molding apparatus exclusively conveys the forming raw material in the horizontal direction while kneading the forming raw material with the biaxial screw arranged horizontally.
- a “ram type” extrusion apparatus is used.
- a “ram type” extrusion molding apparatus is used in the manufacture of a structure that deforms due to its own weight when extruded in the horizontal direction (for example, a honeycomb structure having a large diameter).
- the larger the size the smaller the quantity that can be produced with one molding material input, and the more the number of molding material inputs.
- the influence of the above-mentioned “raw material loss at the seam of the forming raw material” on the production efficiency increases, which is not preferable.
