Design Guidelines
The mould core-cavity approach
Consider core-cavity approaches when possible
As an alternative to deep ribs, consider using the illustrated type of core-cavity approach to produce a similar geometry.
This mould will be faster and less expensive to manufacture, and the quality of the final part will be improved (polishing is much easier on core-cavity geometries than down inside deep ribs).

Deep Rib Approach
Box designed with walls as ribs. Higher cost to machine and polish cavity.
|
Core Cavity Approach
Box designed thru core-cavity method. Can get to features with bigger faster cutter. Easier and faster to polish.
