Manufacturing method of honeycomb formed body and manufacturing method of honeycomb structure
The invention provides a manufacturing method of a honeycomb formed body and a manufacturing method of a honeycomb structure, aiming to obtain a large number of honeycomb formed bodies and honeycomb structures from a predetermined amount of forming raw material while suppressing occurrence of defective products. The manufacturing method of a honeycomb formed body includes a forming step of extruding a coupled forming raw material billet 19 from a honeycomb body forming die 41 to obtain a honeycomb-shaped formed product 20, the coupled forming raw material billet having a colorant 15 applied on the coupling surface of at least one forming raw material billet 11 two interconnected forming raw material billets 11; a cutting step of cutting the formed product 20 to obtain a plurality of honeycomb formed bodies; and a screening step for screening the plurality of honeycomb formed bodies into a colorant-containing honeycomb formed bodies showing the colorant on the cutting surface and a colorant non-containing honeycomb formed bodies without showing the colorant on the cutting surface.
