3D Fiber Mold Sidewall Profile for Easy Stacking Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fiber-containing materials are difficult to stack and unstack due to strong adhesion and friction between the fibers, leading to increased force requirements and potential damage during handling.
Innovation Solution
A three-dimensional molded body with a circumferential side wall featuring a degressive profile, reducing contact surfaces by varying the cross-section from the edge to the base, and incorporating undercuts and stacking shoulders to facilitate easy stacking and unstacking.

1Volume of moving object
If molded parts made of fiber-containing material are stacked to reduce transport space, then space requirement is reduced, but strong adhesion and friction between fibers cause difficulty in stacking and unstacking, requiring great force and potentially damaging the molded parts
Solution Approach 1:
The molded part features an asymmetric side wall profile where the cross-sectional area varies along the height, creating a tapered geometry that reduces contact surface area between stacked parts. This asymmetric design allows the side walls to slide past each other more easily during stacking and unstacking, reducing adhesion and friction effects while maintaining compact transport volume
Solution Approach 2:
The side wall is designed with locally varying properties - the cross-sectional area changes at different heights of the molded part. This local variation in geometry creates zones of different contact pressure and friction when stacked, with reduced contact at critical areas, thereby facilitating easier separation while maintaining overall structural integrity

AI summary
A three-dimensional molded body of fiber-containing material and a method for producing a three-dimensional molded body of fiber-containing material are described. The molded body has a circumferential side wall that surrounds an interior of the molded body. The side wall has a degressive profile at least in portions, between an edge region and a base region, where the cross section of the side wall in the base region is smaller than the cross section in the edge region.
