Abstract:
A method for making a shoebox includes preparing a pulp tank and a mold which includes a first upper mold, a first lower mold and a second lower mold; a step of forming a flat sheet of a semi-final product which includes closing the first upper and lower molds to produce the semi-final product; a step of vacuum suction and mold movement which includes vacuum sucking the semi-final product to the first upper mold, moving the first upper mold to above the second lower mold; a step of hot pressing of the semi-final product into a flat sheet of a final product with patterns and fold lines by closing and heating the first upper mold and the second lower mold; and a step of separating the first upper mold and the second lower mold, taking out the final product and folding it into a shoebox.
