I would like to understand what’s the best optimization in terms of design for a single mold, dual cavity of a two-part box (top and bottom parts) which should be hold together with 4 screws without any clip. For other reasons not drawn, both parts should be roughly the same height – therefore the box is cut in the middle.
From a manufacturing point of view only, which following injection molding option is better for a single mold with two cavities?
Option A:
- to have 4 pillars on both bottom and top parts, that are at same height of each part. Basically, the 4 screws will be inside the pillars in the middle of the box.
Option B:
- to have 4 pillars on one part ONLY, that are at the double height of that part. The 4 screws will be close to the main wall of the other part.
