The mold design must meet the structural requirements of pulp molded products, and the structure of pulp molded products must not only meet the conditions of use and molding process, but also meet the requirements of mold design and manufacturing.
Therefore, before designing pulp molding molds, the structure of pulp molding products must be fully analyzed and studied in order to coordinate and unify the economic rationality and technical feasibility of product design and mold design.
During the molding process of pulp molded products, pulp molded products must enter the mold multiple times to finally complete the product manufacturing process. This is because pulp molded products are formed on a single convex or concave mold. After molding, they must be placed in the mold cavity after the convex and concave molds are closed. Transfer, the wet paper blank transferred to the shaping mold is pressurized and heated in the shaping mold and then formed.
Therefore, pulp molding molds are divided into forming molds, shaping molds, shaping molds, transfer molds and die-cutting molds, etc. There are two types of molding processes, one is adsorption molding and the other is compression molding. Compression molding molds are somewhat similar to rubber plastic molds, while adsorption molding molds are more special and complex.
