Abstract
An asymmetric mold core for forming curved floor openings in pallets is taught. The mold core contains: a base, the base attachable to a frame in a rotomold, a bottom section integral at a distal end to the base, the bottom section comprising a bottom convex curve having a bottom convex curve radius and a bottom convex curve rotational center, a top section integral at a distal end to the base, the top section comprising a top convex curve, the top convex curve having a top convex curve radius and a top convex curve rotational center, the top convex curve radius being different from the bottom convex curve radius and the top convex curve rational center differing from the bottom convex curve rotational center; a first side section, the first side section positioned and integral at a distal end to the base and positioned between and integral with the bottom section and the top section; a second side section the second side section positioned and integral at a distal end to the base and positioned between and integral with the bottom section and the top section, the second side section positioned parallel to the first side section; and a face.
