<p>PURPOSE: To provide a method for molding a raising seedling device designed to efficiently produce uniform raising seedling devices intended to reduce their cost by preventing developing molding defects and/or casting fins to the utmost. CONSTITUTION: In the method for molding a raising seedling device made of a synthetic resin in such fashion that the opening 2a... sides of many pots 2... communicate with one another, the bottom 2b... sides are independent of one another, and these bottoms 2b have holes 2d... respectively, an injection molding is conducted by using a mold to make a raising seedling device with no holes 2d... at the bottoms 2b... of the pots 2..., and these bottoms 2b... are punched with the holes 2d....</p> |
